Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a keyless entry system for a vehicle, and in particular, a technology for lighting a lamp for unlocking a vehicle door and illuminating the surroundings of the vehicle when receiving an unlock signal from a portable device. Belonging to the field.
[0002]
[Prior art]
  Conventionally, a keyless entry system for unlocking a vehicle door by remote control or by approaching the owner (occupant) of the vehicle is well known, and for example, as disclosed in JP-A-7-228191. In addition, a lamp that illuminates the road surface is provided near the door (door mirror), and when the unlock signal is received from the portable device, the door is unlocked and the lamp is turned on. Are known.
[0003]
[Problems to be solved by the invention]
  By the way, when providing a lamp like the above-mentioned conventional example, it is desirable to provide a plurality of lamps, for example, on the driver's seat side and the passenger seat side. In this way, when the surroundings of the vehicle are very dark, not only the driver but also the passenger can check the position of the handle and the foot of the door to be opened. In addition, even if there is no passenger, a burglar may be lurking in the vicinity of the passenger's side door, so the driver can check the situation on the passenger's side by lighting the lamp. Safety against burglaries and the like can also be improved.
[0004]
  When a plurality of lamps are provided as described above, normally, the plurality of lamps are turned on simultaneously. However, if a plurality of lamps are turned on at the same time, there is a possibility that the safety against a hidden robbery or the like is lowered. That is, for example, if the lamps on the side closer to and farther from the occupant carrying the portable device are lit simultaneously, the robber lurking on the far side is usually directed only to the side closer to the occupant's attention. The possibility of overlooking etc. increases. In addition, as the number of lamps increases, current consumption increases and battery consumption becomes a problem.
[0005]
  The present invention has been made in view of such a point, and an object thereof is to unlock a vehicle door and illuminate the surroundings of the vehicle when an unlock signal is received from a portable device. When the lamp is turned on, it is intended to improve occupant convenience, to reliably improve crime prevention and to suppress battery consumption as much as possible.
[0006]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention provides a plurality of lamps.(Driver side lamp and passenger side lamp)When an unlock signal is received from the portable device and the plurality of lamps are turned on, a specific lamp among the plurality of lamps is provided.(Driver side lamp)The lighting timing of other lamps(Passenger side lamp)Delayed against.
[0007]
  Specifically, in the first aspect of the invention, a locking / unlocking means for locking / unlocking the door of the vehicle, a lamp provided in the vehicle for illuminating the periphery of the vehicle by lighting, and a portable device for transmitting an unlock signal And an in-vehicle control means for unlocking the door of the vehicle by the locking / unlocking means and turning on the lamp when an unlock signal is received from the portable device. .
[0008]
  A plurality of the lamps are provided, and when the vehicle-mounted control means receives the unlock signal from the portable device and lights the plurality of lamps, the lighting timing of a specific lamp among the plurality of lamps Configured to delay with respect to other lampsThe plurality of lamps are a driver's seat side lamp provided on the driver's seat side of the vehicle and a passenger's seat side lamp provided on the passenger's seat side, and the vehicle-mounted control means further includes the driver's seat side lamp As a specific lamp, the lighting timing is delayed with respect to the passenger side lamp.Shall.
[0009]
  With the above-described configuration, by turning on the plurality of lamps, a plurality of occupants can check the position of the handle and the foot of the door to be opened, thereby improving the convenience of the occupant.In addition, since the passenger side lamp is lit first, the occupant's attention on the driver's seat outside the vehicle is first directed to the passenger side before riding,The possibility of overlooking lurking robbers and the like is reduced, and crime prevention can be improved with certainty.And since the driver's seat side lamp lights up when the occupant finishes confirming the safety on the passenger seat side, it is possible to sufficiently check the handle position and the feet of the driver's seat door.In addition, current consumption can be suppressed by the amount by which the lighting timing of the specific lamp is delayed.
[0010]
  Claim2In the invention of claim1In this invention, the side where the occupant before boarding is provided with the lamp that is lit on the outside of the vehicle when the lamp that is lit before the specific lamp is lit from the side on which the specific lamp is provided on the outside of the vehicle. It is assumed that a confirmation means capable of confirming the lower part of the vehicle is provided.
[0011]
  In this way, the confirmation means can confirm the lower part of the vehicle that is not normally visible on the opposite side of the vehicle with the occupant, and even if a burglar or the like crouches on that part, It can be discovered and crime prevention can be further improved.
[0012]
  Claim3In the invention of claim1 or 2In the invention, the portable device is configured to be able to transmit a command signal by operating an operation switch provided on the portable device, and the vehicle-mounted control means is configured to transmit another lamp of the specific lamp based on the command signal from the portable device. It is assumed that the lighting delay time is reduced.
[0013]
  As a result, the lighting delay time can be shortened according to the situation, and for example, it is possible to respond to a request to quickly illuminate the vicinity of the door to be opened with the specific lamp. Therefore, usability can be improved.
[0014]
  In the invention of claim 4, in any one of claims 1 to 3, the vehicle-mounted control means unlocks only the driver's seat door or receives all the doors when receiving the unlock signal from the portable device. When it is determined that only the driver's seat door is to be unlocked by determining the conditions for determining whether to unlock the driver's seat, the driver's side lamp is used as a specific lamp and its lighting timing is delayed with respect to the passenger's side lamp It shall be comprised so that it may make it.

[0019]
  Hereinafter, the signal processing operation performed by the CPU 4 of the transmitter 1 will be described with reference to FIGS. 4 and 5, and the signal processing operation performed by the CPU 16 of the vehicle-mounted device 15 will be described with reference to FIGS. 6 and 7. FIG. 3 shows the order of signals communicated between the transmitter 1 and the in-vehicle device 15 via the keyless transceivers 11 and 26.
[0020]
  First, in the signal processing operation of the CPU 4 of the transmitter 1, as shown in FIGS. 4 and 5, it is determined whether or not the operation of the unlock operation switch 6 is detected in the first step SA1, and this determination is not detected. If NO, the process proceeds directly to step SA3. If the determination is YES, the process proceeds to step SA2, and a pre-unlock signal including a predetermined ID code is transmitted to the vehicle-mounted device 15 via the keyless transceivers 11 and 26. Then, the process proceeds to step SA3.
[0021]
  In step SA3, it is determined whether or not the unlock request signal is transmitted from the in-vehicle device 15 as a response to the pre-unlock signal and the signal is received. When this determination is NO, the process proceeds to step SA5 as it is. When the determination is YES, the process proceeds to step SA4, and the ID code included in the unlock request signal is rewritten by a predetermined calculation as a response to the unlock request signal. After transmitting the unlock signal to the vehicle-mounted device 15, the process proceeds to step SA5.
[0022]
  In step SA5, it is determined whether or not the first unlock confirmation signal is received from the vehicle-mounted device 15 as a response to the unlock signal. When this determination is NO, the process proceeds directly to step SA7, while when the determination is YES, the process proceeds to step SA6, and a part (driver's seat door) of all the vehicle doors is unlocked on the display 8 of the transmitter 1. “Partial door unlock” is displayed, and the buzzer 10 is blown once before proceeding to step SA7.
[0023]
  In step SA7, it is determined whether or not the second unlock confirmation signal is received from the in-vehicle device 15 as a response to the unlock signal. When this determination is NO, the process proceeds to step SA9 as it is, while when the determination is YES, the process proceeds to step SA8 and "all door unlock" indicating that all the doors of the vehicle are unlocked on the display 8 of the transmitter 1. Is displayed, and the buzzer 10 is blown twice before proceeding to Step SA9.
[0024]
  In step SA9, it is determined whether or not the operation of the lock operation switch 5 has been detected. When this determination is NO in which the operation is not detected, the process proceeds to step SA11 as it is, and when the determination is YES, the process proceeds to step SA10 to transmit a pre-lock signal including a predetermined ID code to the vehicle-mounted device 15, and then to step Proceed to SA11.
[0025]
  In step SA11, it is determined whether or not the lock request signal is transmitted as a response to the pre-lock signal from the in-vehicle device 15 and the signal is received. When this determination is NO, the process proceeds to step SA13 as it is, and when the determination is YES, the process proceeds to step SA12 and a lock signal obtained by rewriting the ID code included in the lock request signal as a response to the lock request signal by a predetermined calculation. Is transmitted to the vehicle-mounted device 15, and then the process proceeds to Step SA13.
[0026]
  In step SA13, it is determined whether or not the lock confirmation signal is transmitted as a response to the lock signal from the in-vehicle device 15 and the signal is received. If this determination is NO, the process proceeds directly to step SA15 while the determination is YES. In step SA14, the process proceeds to step SA14, "lock" indicating that all the doors of the vehicle are locked is displayed on the display 8 of the transmitter 1, and the buzzer 10 is blown three times before proceeding to step SA15.
[0027]
  In step SA15, it is determined whether or not the operation of the light operation switch 7 is detected. When this determination is NO in which the operation is not detected, the process proceeds to step SA17 as it is. When the determination is YES, the process proceeds to step SA16, and a prelight signal (command signal) including a predetermined ID code is transmitted to the in-vehicle device 15. Then, the process proceeds to step SA17.
[0028]
  In the step SA17, it is determined whether or not the light request signal is transmitted as a response to the prelight signal from the in-vehicle device 15 and the signal is received. When this determination is NO, the process returns as it is. When the determination is YES, the process proceeds to step SA18, where a write signal (command) is rewritten by a predetermined calculation as an ID code included in the write request signal as a response to the write request signal. Signal) is transmitted to the in-vehicle device 15 and then the process returns.
[0029]
  When the determination at step SA15 is NO, the processing operation at step SA17 is omitted and the process returns. When the determination at step SA15 is YES, the processing at step SA18 is performed instead of the processing operation at step SA16. You may make it return by performing operation | movement.
[0030]
  On the other hand, in the signal processing operation of the CPU 16 of the in-vehicle device 15, as shown in FIGS. 6 and 7, in the first step SB 1, it is determined whether or not the ignition switch 18 is in the OFF state. When the determination is NO, the process returns as it is, while when the determination is YES when the switch is OFF, the process proceeds to step SB2 to determine whether or not the pre-unlock signal transmitted from the transmitter 1 has been received. When this determination is NO with no signal reception, the process proceeds directly to step SB4. When the determination is YES with reception, the process proceeds to step SB3, and the ID code included in the pre-unlock signal is sent as a response to the pre-unlock signal. The unlock request signal rewritten by a predetermined calculation is transmitted to the transmitter 1, and then the process proceeds to step SB4.
[0031]
  In step SB4, it is determined whether or not the pre-lock signal transmitted from the transmitter 1 has been received. When this determination is NO with no signal reception, the process proceeds to step SB6 as it is, while when the determination is YES with reception, the process proceeds to step SB5 and an ID code included in the prelock signal is set as a predetermined response as a response to the prelock signal. After the lock request signal rewritten by calculation is transmitted to the transmitter 1, the process proceeds to step SB6 (Note that the ID code rewriting in steps SB3 and SB5 is not necessarily performed).
[0032]
  In step SB6, based on the output signal of the door key cylinder switch 20, it is determined whether or not there is a door lock operation by the key cylinder. When this determination is NO with no door lock operation, the routine proceeds to step SB7, where it is determined whether or not a lock signal transmitted from the transmitter 1 and whose ID code matches is received. If NO when no lock signal is received, the process proceeds to step SB8.
[0033]
  In step SB8, based on the output signal of the door key cylinder switch 20, it is determined whether or not there is a door unlock operation by the key cylinder. If this determination is NO with no door unlock operation, the process proceeds to step SB9, where it is determined whether an unlock signal transmitted from the transmitter 1 and matching the ID code is received. If this determination is NO with no reception of the unlock signal, the process directly proceeds to step SB22.
[0034]
  When the determination at step SB6 is YES with a door lock operation, or when the determination at step SB7 is YES with reception of a lock signal, the process proceeds to step SB10, and if the door mirror is in a non-retracted state, the door mirror storage actuator 27 is operated to store the door mirror (note that the stored door mirror is returned to the original non-storage state by the operation of the door mirror storage actuator 27, but the return timing is the time when the unlock signal is received, This is when the ignition switch 18 is turned on or when a manual switch that can be operated by the passenger is operated). Then, in the next step SB11, the mirror surface driving actuator 28 is operated to drive the door mirror so that the mirror surface faces downward (the mirror surface directed downward is restored to the original by the mirror surface driving actuator 28). The return timing is the same as the return timing of the door mirror to the original non-retracted state). When the door is unlocked in the next step SB12, the door lock actuator 23 is operated to lock the door. In step SB13, a lock confirmation signal is transmitted to the transmitter 1 immediately after the door lock operation, and the horn 24 is blown three times or the hazard 25 is lit three times. After that, the process proceeds to step SB22.
[0035]
  When the determination at step SB8 is YES with a door unlock operation, or when the determination at step SB9 is YES with reception of an unlock signal, the process proceeds to step SB14, where some of the doors (driver's seat) A condition determining subroutine for determining whether to unlock only the door) or all the doors is executed, and in the next step SB15, it is determined whether or not it is determined that the predetermined condition is satisfied in the condition determining subroutine. judge.
[0036]
  When the determination in step SB15 is NO, the process proceeds to step SB16, and if the driver's seat door is locked, only the door lock actuator 23 of the driver's seat door is unlocked, and in the next step SB17, The door mirror light subroutine 1 relating to the lighting control of the door mirror light 22 is executed, and in step SB18, a first unlock confirmation signal is transmitted to the transmitter 1 immediately after the door unlocking operation, and the horn 24 is blown once. Alternatively, after the hazard 25 is turned on once, the process proceeds to step SB22.
[0037]
  On the other hand, when the determination in step SB15 is YES, the process proceeds to step SB19, where the door lock actuator 23 of all the doors is door-locked, and in the next step SB20, the door mirror light subroutine related to the lighting control of the door mirror light 22 2 is executed, and at step SB21, the second unlock confirmation signal is transmitted to the transmitter 1 immediately after the door unlocking operation, and the horn 24 is blown twice or the hazard 25 is turned on twice. After that, the process proceeds to step SB22.
[0038]
  In step SB22, it is determined whether or not the prewrite signal transmitted from the transmitter 1 has been received. If this determination is NO with no signal reception, the process proceeds directly to step SB24, while the determination is YES with reception. In some cases, the process proceeds to step SB23, and as a response to the prewrite signal, a write request signal in which the ID code included in the prewrite signal is rewritten by a predetermined calculation is transmitted to the transmitter 1 and then the process proceeds to step SB24 (note that the above step It is not always necessary to rewrite the ID code in SB23).
[0039]
  In step SB24, it is determined whether or not a write signal transmitted from the transmitter 1 and whose ID code matches is received. If this determination is NO with no reception of the write signal, the process returns as it is. When YES is received with the reception of the light signal, the process proceeds to step SB25, the door mirror light subroutine 3 relating to the lighting control of the door mirror light 22 is executed, and the process returns.
[0040]
  The condition determination subroutine performed in step SB14 will be specifically described with reference to FIG. 8. In the first step SC1, the door by the previous key cylinder is operated within a predetermined time before the door unlock operation by the key cylinder or the reception of the unlock signal. It is determined whether or not there has been an unlock operation. If this determination is NO, the process proceeds to step SC2, and the previous unlock signal is displayed within a predetermined time before the door unlock operation by the key cylinder or the unlock signal is received. It is determined whether or not there is reception. If this determination is NO, the process proceeds to step SC3, where it is determined that the condition is not satisfied, and the process ends.
[0041]
  On the other hand, when the determination at step SC1 is YES or when the determination at step SC2 is YES, the process proceeds to step SC4, and the door is locked by the key cylinder after the previous door unlock operation or the previous unlock signal is received. It is determined whether an operation or a lock signal has been received. When this determination is YES, the process proceeds to step SC3. When the determination is NO, the process proceeds to step SC5, and it is determined that the condition is satisfied, and the process ends.
[0042]
  That is, only the driver's seat door is unlocked first by the first door lock operation by the key cylinder, and the second door lock operation (or operation of the unlock operation switch 6 of the transmitter 1) is performed within a predetermined time from the operation. If you do, all doors will be unlocked. Similarly, only the driver's seat door is unlocked first by the first operation of the unlock operation switch 6, and the second operation (or door lock operation by the key cylinder) is performed within a predetermined time from the operation. All the doors are unlocked.
[0043]
  FIG. 9 shows a modified example 1 of the condition determination subroutine, in which it is determined whether or not the condition is satisfied depending on the locking / unlocking state of the driver's seat door. Specifically, in the first step SD1, it is determined whether or not the driver's seat door is unlocked. If this determination is NO in the locked state, the process proceeds to step SD2, where it is determined that the condition is not satisfied and the process ends. When the determination is YES in the unlocked state, the process proceeds to step SD3, where it is determined that the condition is satisfied, and the process ends.
[0044]
  In step SD1, instead of determining whether the driver's seat door is unlocked, it may be determined whether any of the doors is unlocked.
[0045]
  FIG. 10 shows a modification 2 of the above condition determination subroutine, which has an identification signal indicating whether the unlock signal itself is an all-door unlock signal or a partial door unlock signal (the first ON operation of the unlock operation switch 6). If there is a partial door unlock signal, and if it is the second ON operation within a predetermined time from the first ON operation, it has an all door unlock signal). By determining whether or not the condition is satisfied, it is determined. Specifically, in the first step SE1, it is determined whether or not the unlock signal is a full door unlock signal. If this determination is NO and the unlock signal is a partial door unlock signal, step SE2 is performed. On the other hand, when it is determined that the condition is not satisfied, the process ends. When the determination is YES, the process proceeds to step SE3, where it is determined that the condition is satisfied and the process ends.
[0046]
  The door mirror light subroutine 1 performed in step SB17 will be specifically described with reference to FIG. 11. In the first step SF1, as in step SB10, if the door mirror is in the non-retracted state, the door mirror retracting actuator 27 is operated. The door mirror is stored, and in the next step SF2, similarly to step SB11, the mirror surface drive actuator 28 is operated to drive the door mirror to face downward. By storing the door mirror in step SF1 and driving the mirror surface of the door mirror in step SF2, an occupant before boarding from the driver seat side on the outside of the vehicle to the lower part of the vehicle on the passenger seat side on the outside of the vehicle (from the door window) The lower part of the vehicle can also be seen (conversely, the lower part of the vehicle on the driver's seat side can also be seen from the passenger seat side).
[0047]
  In the next step SF3, the door mirror light 22 on the side opposite to the door unlocked in the above step SB16 (passenger seat side) is turned on, and in the next step SF4, after a predetermined delay time from the lighting, the door mirror light is unlocked in step SB16. The door mirror light 22 on the same side as the door (driver's seat side) is turned on, and the process ends.
[0048]
  The door mirror light 22 is turned off when the corresponding door is opened (detected by the door opening sensor 21), after a predetermined time has elapsed, or a turn-off operation switch or the like provided separately on the transmitter 1 is operated. When
[0049]
  FIG. 12 shows a modification of the door mirror light subroutine 1(Shown as a reference example different from the present invention)In this modified example, in step SG1, the door mirror light 22 on the same side (driver's seat side) as the unlocked door is turned on, and the process ends.
[0050]
  In the door mirror light subroutine 2 performed in step SB20, as shown in FIG. 13, all the door mirror lights 22 are turned on in step SH1 and the process is ended.
[0051]
  In the door mirror light subroutine 3 performed in step SB25, as shown in FIG. 14, the door mirror light 22 is turned on in step SH1 and the process is terminated.
[0052]
  FIG. 15 shows a first modified example of the door mirror light subroutine 3. In the first modified example, the door mirror light 22 provided on the driver's seat side or the light signal arrival direction side is turned on in step SJ1, and the process ends.
[0053]
  FIG. 16 shows a second modification of the door mirror light subroutine 3. In the second modification, in step SK1, the predetermined delay time in the current or next step SF4 is reduced and corrected (including setting the predetermined delay time to zero). ) And finish.
[0054]
  Next, the operation of the first embodiment will be described. First, when the unlock operation switch 6 of the transmitter 1 is turned on, a pre-unlock signal is transmitted from the transmitter 1 to the in-vehicle device 15. In the in-vehicle device 15 that has received the pre-unlock signal from the transmitter 1, the ID code included in the pre-unlock signal is rewritten by a predetermined calculation, and an unlock request signal including the rewritten ID code is transmitted from the in-vehicle device 15 to the transmitter. 1 is transmitted. In the transmitter 1 that has received the unlock request signal from the in-vehicle device 15, the ID code included in the unlock request signal is rewritten as a response to the unlock request signal, and an unlock signal including the rewritten ID code is received. It is transmitted from the transmitter 1 to the in-vehicle device 15.
[0055]
  Subsequently, the in-vehicle device 15 determines whether to unlock only the driver's seat door or to unlock all the doors when the unlock signal transmitted from the transmitter 1 is received and the ID codes match. If the condition determination result is not satisfied (when the first ON operation of the unlock operation switch 6 is performed), only the door lock actuator 23 of the driver's door is operated to unlock the door. To unlock the locked driver's seat door. At substantially the same time as the unlocking of the driver seat door, the passenger side door mirror light 22 on the opposite side of the driver seat door is turned on, and the driver side door mirror light 22 is turned on after a predetermined delay time from the lighting. That is, the lighting timing is delayed with respect to the door mirror light 22 on the passenger seat side using the door mirror light 22 on the driver seat side as a specific lamp. At substantially the same time as the unlocking of the driver's seat door, the door mirror is retracted by the door mirror retracting actuator 27 and driven by the mirror surface driving actuator 28 so that the mirror surface of the door mirror faces downward. When the front occupant lights the door mirror light 22 on the passenger seat side (the lamp that lights up before the specific lamp) from the driver seat side (the side where the specific lamp is provided) on the outside of the vehicle, It will be in the state which can confirm the vehicle lower part equivalent part. In other words, the door mirror retracting actuator 27 and the mirror surface driving actuator 28 correspond to a portion corresponding to the lower part of the vehicle on the passenger seat side outside the vehicle when the occupant before boarding lights the door mirror light 22 on the passenger seat side from the driver seat side on the vehicle outer side. The confirmation means which can confirm is comprised. When the modified example of the door mirror light subroutine 1 is executed, the door mirror light 22 on the driver's seat side is turned on substantially simultaneously with the unlocking of the driver's seat door. Thereafter, a first unlock confirmation signal is transmitted from the in-vehicle device 15 to the transmitter 1, and the horn 24 is blown once or the hazard 25 is lit once. In the transmitter 1 that has received the first unlock confirmation signal from the in-vehicle device 15, “partial door unlock” indicating the unlocked state of the partial door of the vehicle is displayed on the display 8 and the buzzer 10 is turned on once. Blow.
[0056]
  On the other hand, if the condition determination result is satisfied (when the second ON operation is performed within a predetermined time from the first ON operation of the unlock operation switch 6), the door lock actuator 23 of all the doors is set to the door. All doors are unlocked by unlocking (the driver's seat door is already unlocked, so other doors (passenger seat door and left and right rear seat doors) other than the driver's door are substantially unlocked. ) At this time, if the predetermined delay time has not passed since the lighting of the door mirror light 22 on the passenger seat side and the door mirror light 22 on the driver seat side is in a non-lighting state, the door mirror on the driver seat side is substantially simultaneously with the unlocking of all the doors. Although the light 22 is turned on, if the predetermined delay time has elapsed since the turning of the door mirror light 22 on the passenger seat side, the door mirror light 22 on the driver seat side has already been turned on, so there is no substantial change. . When the modified example of the door mirror light subroutine 1 is executed, the passenger side door mirror light 22 is turned on substantially simultaneously with the unlocking of the doors other than the driver's door. In other words, in this case, the lighting timing of the passenger side door mirror light 22 is delayed with respect to the driver side door mirror light 22, and the lighting timing of each door mirror light 22 corresponds to each door mirror light 22. The timing coincides with the unlocking timing of the driver's seat door and the passenger's seat door. Thereafter, a second unlock confirmation signal is transmitted from the in-vehicle device 15 to the transmitter 1, and the horn 24 is blown twice or the hazard 25 is lit twice. In the transmitter 1 that has received the second unlock confirmation signal from the in-vehicle device 15, “all door unlock” indicating the unlock state of all the doors of the vehicle is displayed on the display 8 and the buzzer 10 sounds twice. .
[0057]
  When the light operation switch 7 of the transmitter 1 is turned on, a prelight signal is transmitted from the transmitter 1 to the in-vehicle device 15 via the keyless transceivers 11 and 26. In the in-vehicle device 15 that has received the prewrite signal from the transmitter 1, the ID code included in the prewrite signal is rewritten by a predetermined calculation as a response to the prewrite signal, and a write request signal including the rewritten ID code is received. It is transmitted from the in-vehicle device 15 to the transmitter 1. In the transmitter 1 that has received the write request signal from the in-vehicle device 15, the ID code included in the write request signal is rewritten, and the write signal including the rewritten ID code is transmitted from the transmitter 1 to the in-vehicle device 15. The in-vehicle device 15 receives the light signal transmitted from the transmitter 1 and forcibly turns on the door mirror light 22 when the ID codes match. When the first modification of the door mirror light subroutine 3 is executed, the door mirror light 22 provided on the driver's seat side or the light signal arrival direction side is forcibly turned on. Further, the modification of the door mirror light subroutine 3 2, the lighting delay time (the predetermined delay time) of the driver side door mirror light 22 with respect to the passenger side door mirror light 22 is shortened, and the driver side door mirror light 22 is faster than usual. Light.
[0058]
  Further, when the lock operation switch 5 of the transmitter 1 is turned on, a pre-lock signal is transmitted from the transmitter 1 to the in-vehicle device 15 via the keyless transceivers 11 and 26. In the in-vehicle device 15 that has received the pre-lock signal from the transmitter 1, the ID code included in the pre-lock signal is rewritten by a predetermined calculation as a response to the pre-lock signal, and the lock request signal including the rewritten ID code is transmitted to the in-vehicle device 15. To the transmitter 1. In the transmitter 1 that has received the lock request signal from the in-vehicle device 15, the ID code included in the lock request signal is rewritten, and the lock signal including the rewritten ID code is transmitted from the transmitter 1 to the in-vehicle device 15. When the onboard device 15 receives the lock signal transmitted from the transmitter 1 and the ID code matches, the in-vehicle device 15 stores the door mirror and drives the door mirror so that the mirror surface faces downward, and the door lock actuator 23. Lock the door in the unlocked state. Thereafter, a lock confirmation signal is transmitted from the in-vehicle device 15 to the transmitter 1, and the horn 24 is blown three times or the hazard 25 is lit three times. In the transmitter 1 that has received the lock confirmation signal from the in-vehicle device 15, “lock” indicating the locked state of the vehicle door is displayed on the display 8 and the buzzer 10 sounds three times.
[0059]
  Accordingly, in the first embodiment, since the left and right door mirror lights 22 are lit, a plurality of passengers can confirm the handle position and the foot of the door to be opened, thereby improving the convenience of the passengers. In addition, since the lighting timing on the driver's seat side of the left and right door mirror lights 22 is delayed with respect to the passenger seat side, particularly when there is only one passenger (driver), the passenger must drive outside the vehicle before boarding. When the passenger is on the side of the seat, the passenger side door mirror light 22 is turned on first, so that the passenger's attention is first directed to the passenger's side and the possibility of overlooking a robbery lurking in the passenger's side is reduced. . In addition, when the door mirror light 22 on the passenger seat side is turned on, the door mirror is retracted and the mirror surface of the door mirror faces downward, so that the occupant before boarding can be moved from the driver seat side on the vehicle outer side to the passenger seat side on the vehicle outer side. The lower part of the vehicle (the part below the door window) can be seen, so even if a robber crouches at that part, it can be detected reliably and crime prevention Can be further improved. Then, when the passenger finishes confirming the safety on the passenger side, the door mirror light 22 on the driver's seat is lit, so that the door handle position and the feet can be sufficiently confirmed. Furthermore, current consumption can be suppressed by the amount of delay in the lighting timing of the door mirror light 22 on the driver's seat side.
[0060]
  When the modified example of the door mirror light subroutine 1 is executed, the lighting timings of the left and right door mirror lights 22 coincide with the unlocking timings of the doors corresponding to the left and right door mirror lights 22, respectively. The lock state can be easily understood, and the convenience of the passenger can be further improved.
[0061]
  Furthermore, the door mirror light 22 can be forcibly turned on at any time by turning on the light operation switch 7. In particular, when the modified example of the door mirror light subroutine 1 is executed, by turning on the light operation switch 7 before the driver door is unlocked and the other doors are unlocked, the door mirror light on the passenger seat side is turned on. 22 can be forcibly turned on, and usability can be improved. When the second modification of the door mirror light subroutine 3 is executed, the lighting delay time of the door mirror light 22 on the driver's seat side with respect to the door mirror light 22 on the passenger seat side is changed according to the situation by turning on the light operation switch 7. It can be shortened.
[0062]
  still,carThe lamps that illuminate both sides are not limited to the door mirror lights 22, but may be lamps provided on the side surfaces of the left and right roof rails, for example, and a plurality of lamps are provided on the opposite surfaces in the vehicle width direction of the vehicle as described above.IfGood. TheFurther, three or more lamps may be provided, and four lamps may be provided corresponding to the driver seat door, the passenger seat door, and the left and right rear seat doors, respectively.
[0063]
  (Embodiment 2)
  FIG. 17 shows a second embodiment of the present invention (the same parts as those in FIG. 1 are denoted by the same reference numerals and detailed description thereof is omitted), and the transmitter 1 is put into an operating state on the surface of the transmitter body 2. A power switch 12 is provided, and when the power switch 12 is turned on, an unlock signal is automatically output every predetermined period until a predetermined time (for example, about 1 minute) elapses. It is.
[0064]
  That is, in the second embodiment, the in-vehicle device 15 receives the unlock signal from the transmitter 1 and keeps the door unlockable when the electric field strength of the unlock signal is greater than a predetermined level. When it is detected by the handle switch 19 that the first door handle operation has been performed, the driver's seat door is unlocked and the second door handle operation has been performed within a predetermined time from the first door handle operation. When this is detected, all the doors are unlocked.
[0065]
  Hereinafter, the signal processing operation performed by the CPU 4 of the transmitter 1 will be described with reference to FIGS. 18 and 19, and the signal processing operation performed by the CPU 16 of the vehicle-mounted device 15 will be described with reference to FIGS.
[0066]
  First, in the signal processing operation of the CPU 4 of the transmitter 1, as shown in FIGS. 18 and 19, in the first step SL <b> 1, an elapsed time after the power switch 4 of the transmitter 1 is turned on is predetermined by a timer count. It is determined whether or not it is within the time (whether the ON operation of the power switch 4 is held for a predetermined time). When this determination is NO, the process proceeds to step SL3. When the determination is YES, the process proceeds to step SL2, and a predetermined period (for example, 0.5 to 1 second) set in advance for intermittent transmission of the unlock signal. It is determined whether or not elapses. When this determination is NO when the predetermined period has not elapsed, the process proceeds to step SL3. When YES, the predetermined period has elapsed, the process proceeds to step SL4, and a pre-unlock signal including a predetermined ID code is transmitted to the vehicle-mounted device 15. It progresses to step SL5 later. In step SL3, it is determined whether or not the operation of the unlock operation switch 6 has been detected. If this determination is NO, the process proceeds directly to step SL5. If the determination is YES, the process proceeds to step SL4. Then, the process proceeds to step SL5.
[0067]
  In steps SL5 and SL6, processing operations similar to those in steps SA3 and SA4 in the first embodiment are performed. In step SL7 after step SL6 when the determination in step SL5 is YES, the buzzer is operated for a predetermined period. 10 or the display 8 notifies the unlockable state, and proceeds to step SL8. On the other hand, when the determination in step SL5 is NO, the process proceeds directly to step SL8.
[0068]
  Subsequently, in steps SL8 to SL13, the same processing operations as in steps SA5 to SA10 in the first embodiment are performed, and a predetermined time elapses in step SL14 after step SL13 when the determination in step SL12 is YES. In the meantime, the transmission of the periodic unlock signal is prohibited and the process proceeds to step SL15. On the other hand, when the determination in step SL12 is NO, the process proceeds to step SL15 as it is.
[0069]
  Next, in steps SL15 to SL22, the same processing operation as in steps SA11 to SA18 in the first embodiment is performed. When the determination in step SL21 is NO, the process returns as it is, while when the determination in step SL21 is YES, the process proceeds to step SL15. Return after SL22.
[0070]
  On the other hand, in the signal processing operation of the CPU 16 of the in-vehicle device 15, as shown in FIGS. 20 and 21, in steps SM <b> 1 to SM <b> 9, processing operations similar to those in steps SB <b> 1 to SB <b> 9 in the first embodiment are performed, respectively. If YES in step S10, the process proceeds to step SM10 to determine whether the electric field strength of the received unlock signal is greater than the first predetermined level L1. When this determination is YES when the electric field strength is greater than L1, the process proceeds to step SM17 as in the case where the determination at step SM8 is YES with the door unlocking operation, while when the determination is NO when the electric field strength is ≦ L1, the process proceeds to step SM11. move on.
[0071]
  In step SM11, within a predetermined time from reception of the unlock signal, an unlock signal that is equal to or higher than a second predetermined value L2 (<L1) lower than the first predetermined value L1 and whose ID code matches is received. Determine if you did. When this determination is NO with no signal reception, the process proceeds to step SM13, similarly to when the determination at step SM6 is YES with a door lock operation, or when the determination at step SM7 is YES with reception of a lock signal. In steps SM13 to SM16, the same processing operation as in steps SB10 to SB13 in the first embodiment is performed, and then the process proceeds to step SM25. On the other hand, if the determination is YES with signal reception, the process proceeds to step SM12. It is determined whether or not a lock signal having an electric field strength equal to or higher than the second predetermined value L2 and matching the ID code is received after the reception unlock signal related to the determination of SM11. When this determination is YES with signal reception, the process proceeds to step SM25 through the processing operations of steps SM13 to SM16. When the determination is NO with no signal reception, the process proceeds to step SM25.
[0072]
  In step SM17, a condition determination subroutine is executed to determine whether only a part (driver's seat door) of all doors is unlocked, all doors are unlocked, or the locked state is maintained, In the next step SM18, it is determined how the condition determination result is.
[0073]
  When the determination in step SM18 is “lock maintenance”, the process proceeds to step SM25 as it is. When the determination in step SM18 is “partial door unlock”, the process proceeds to step SM19, and in steps SM19 to SM21, the same processing operations as those in steps SB16 to SB18 in the first embodiment are performed, and then to step SM25. move on. Further, when the determination in step SM18 is “all door unlocked”, the process proceeds to step SM22, and in steps SM22 to SM24, the same processing operations as those in steps SB19 to SB21 in the first embodiment are performed, and then the process proceeds to step SM25. . The specific processing of the door mirror subroutine 1 in step SM20 and the door mirror subroutine 2 in step SM23 is the same as that in the first embodiment (see FIG. 11 or FIG. 12 for the door mirror subroutine 1 and FIG. 13 for the door mirror subroutine 2). reference).
[0074]
  Next, in steps SM25 to SM28, the same processing operations as those in steps SB22 to SB25 in the first embodiment are performed. If the determination in step SM27 is NO, the process returns as it is, while if the determination in step SM27 is YES, the process proceeds to step SM27. Return after SL28. The specific processing of the door mirror subroutine 3 in step SM28 is the same as that in the first embodiment (see FIG. 14, FIG. 15 or FIG. 16).
[0075]
  The condition determination subroutine performed in step SM17 will be specifically described with reference to FIG. 22. In the first step SN1, it is determined which of the door unlock operation by the key cylinder and reception of the unlock signal has occurred. When this determination is “door unlocking operation”, the process proceeds to step SN2, and it is determined whether or not the driver's seat door or the door subjected to the door locking operation is unlocked. If this determination at step SN2 is NO, step SN2 is performed. Proceeding to SN3, it is determined that the door is partially unlocked, and the process ends. On the other hand, if the determination in step SN2 is YES, the process proceeds to step SN4, and it is determined that all the doors are unlocked.
[0076]
  On the other hand, when the determination at step SN1 is “Reception of unlock signal”, the process proceeds to step SN5, where it is determined whether or not the door handle operation has been performed by the door handle switch 19, and this determination is NO with no door handle operation. In the case of, the process proceeds to step SN6, where it is determined that the lock is maintained, and the process is terminated.
[0077]
  In step SN7, it is determined whether or not there was a previous door handle operation within a predetermined time before the door handle operation. If this determination is NO with no door handle operation, the process proceeds to step SN8, and a part thereof On the other hand, when it is determined that the door is locked, the process proceeds to step SN9.
[0078]
  In step SN5, instead of determining whether or not there has been a door handle operation, a predetermined operation such as an operation of bringing a hand close to the door handle (detected by an ultrasonic sensor or the like) or a voice operation (detected by voice recognition) or the like. You may make it determine whether there existed operation. In this case, in step SN7, instead of determining whether or not there was a previous door handle operation, it may be determined whether or not there was a previous predetermined operation.
[0079]
  FIG. 23 shows a first modified example of the above condition determination subroutine. In the first modified example, in the first step SO1, the door unlocking operation by the key cylinder or the previous door unlocking operation is performed within a predetermined time before receiving the unlocking signal. When the determination is NO, the process proceeds to step SO2, and it is determined that the door is partially unlocked. When the determination is YES, the process proceeds to step SO3 and the previous time. It is determined whether there has been a door lock operation after the door unlock operation. When this determination is NO with no door locking operation, the process proceeds to step SO2, while when the determination is YES with door locking operation, the process proceeds to step SO4, where it is determined that all doors are unlocked and the process ends. If the determination at step SO1 is YES, the processing operation at step SO3 may be omitted and the process may proceed directly to step SO4.
[0080]
  FIG. 24 shows a second modification of the condition determination subroutine. In the second modification, whether or not a door handle operation has been performed in the first step SP1 (or whether or not a predetermined operation has been performed as described above). If this determination is NO, the process proceeds to step SP2, and it is determined that the door is partially unlocked. On the other hand, if the determination is YES, the process proceeds to step SP3 to determine that all doors are unlocked. finish.
[0081]
  FIG. 25 shows a third modification of the condition determination subroutine. In the third modification, it is determined in the first step SQ1 whether or not there has been a door handle operation. If this determination is NO, the process proceeds to step SQ2. On the other hand, when it is determined that the lock is maintained and the process ends, when the determination is YES, the process proceeds to step SQ3. In this step SQ3, it is determined whether or not there has been a predetermined operation as described above after the door handle operation. If this determination is NO with no predetermined operation, the process proceeds to step SQ4 to unlock some doors. On the other hand, if the determination is YES with a predetermined operation, the process proceeds to step SQ5, where it is determined that all doors are unlocked and the process ends.
[0082]
  Therefore, in the second embodiment, a pre-unlock signal is transmitted from the transmitter 1 to the in-vehicle device 15 every predetermined period until the predetermined time elapses after the power switch 4 of the transmitter 1 is turned on. Even if the unlock operation switch 6 of the transmitter 1 is directly turned ON, a pre-unlock signal is transmitted from the transmitter 1 to the in-vehicle device 15. In the vehicle-mounted device 15 that has received the pre-unlock signal from the transmitter 1, the ID code included in the pre-unlock signal is rewritten by a predetermined calculation, and the unlock including the rewritten ID code is performed, as in the first embodiment. A request signal is transmitted from the in-vehicle device 15 to the transmitter 1. In the transmitter 1 that has received the unlock request signal from the in-vehicle device 15, the ID code included in the unlock request signal is rewritten as a response to the unlock request signal, and an unlock signal including the rewritten ID code is received. It is transmitted from the transmitter 1 to the in-vehicle device 15.
[0083]
  Subsequently, the in-vehicle device 15 receives the unlock signal transmitted from the transmitter 1, and if the ID code matches and the electric field strength of the received unlock signal is greater than the first predetermined value L1, Although the locked state is maintained, the door can be unlocked at any time by the door handle operation. Then, only the driver's seat door is unlocked first by the first door handle operation, and the door mirror light 22 on the passenger seat side is turned on substantially simultaneously with the unlocking of the driver's seat door, and after a predetermined delay time from this lighting, The door mirror light 22 on the driver's seat side is turned on. When the modified example of the door mirror light subroutine 1 is executed, the door mirror light 22 on the driver's seat side is turned on substantially simultaneously with the unlocking of the driver's seat door. On the other hand, if the second operation is performed within a predetermined time from the first door handle operation, all the doors are unlocked. At this time, the predetermined delay time has not elapsed since the lighting of the door mirror light 22 on the passenger seat side. If the door mirror light 22 on the driver's seat side is in a non-lighting state, the door mirror light 22 on the driver's seat side is turned on substantially simultaneously with the unlocking of all the doors. When the modified example of the door mirror light subroutine 1 is executed, the passenger side door mirror light 22 is turned on substantially simultaneously with the unlocking of the doors other than the driver's door.
[0084]
  When the light operation switch 7 of the transmitter 1 is turned on, the door mirror light 22 is forcibly turned on as in the first embodiment, or the door mirror light 22 on the passenger side of the door mirror light 22 on the driver side. The lighting delay time with respect to is reduced.
[0085]
  Thus, although the door unlocking method is different from that of the first embodiment, the lighting timing of the left and right door mirror lights 22 is the same as that of the first embodiment. Therefore, also in this Embodiment 2, the same effect as the said Embodiment 1 is acquired..
[0086]
【The invention's effect】
  As described above, according to the vehicle keyless entry system of the present invention, a plurality of lamps that illuminate the periphery of the vehicle by lighting.(Driver side lamp and passenger side lamp)When an unlock signal from a portable device is received and the plurality of lamps are turned on, a specific lamp among the plurality of lamps is provided.(Driver side lamp)The lighting timing of other lamps(Passenger side lamp)Therefore, while improving the convenience of the occupant, it is possible to reliably improve crime prevention and suppress battery consumption as much as possible.
