Further, the door lock control device 10 confirms the vehicle lock instruction from the user of the vehicle carrying the portable key 20 based on the instruction signal SI output from the keyless entry receiver 101. The authentication of the portable key 20 in the door lock control device 10, the recognition of the position of the portable key 20, and the confirmation of the instruction from the user of the vehicle can be performed by the existing technology, and thus the detailed description thereof will be omitted.

The door lock control device 10 operates when the instruction signal SI output from the keyless entry receiver 101 or the operation signal LOCK-SW output from the external door lock switch 30 is an instruction to lock the door, that is, the vehicle When the user instructs to lock the door, the door lock motor 50 is controlled to lock each door. At this time, the door lock control device 10 immediately locks all the doors based on the recognized position of the portable key 20 and the door state signal output by the door switch 40 (that is, the normal state). Lock the door in the street) or lock the door in the reserved lock mode. As a result, when it is determined that the doors are locked in the reservation lock mode, the door lock control device 10 activates the reservation lock mode determination unit 110 after locking all the doors.

In the reserved lock mode, the reserved lock mode determination unit 110 activates the assist function of the open door to shift the open door to the closed state. After that, the reservation/locking mode determination unit 110 recognizes the position of the corresponding portable key 20. Further, the reservation/locking mode determination unit 110 determines the open/closed state of each door based on the door state signal output by the door switch 40. Then, the reservation locking mode determination unit 110 activates a security function provided in the vehicle based on the recognized position of the corresponding portable key 20 and the open/closed state of each door. In addition, the reserved lock mode determination unit 110 notifies the notification means (the storage mirror motor 60, the lamp 70 (left side) that the opened door is moved to the closed state and the security function is activated in the reserved lock mode. The user of the vehicle is notified using the lamp 70L, the right lamp 70R), the horn 80, and the buzzer 90).

In the keyless entry system 1, the reservation locking mode determination unit 110 outputs a vehicle state signal indicating the operation of the assist function of the open door, the recognized position of the portable key 20 and the open/closed state of each door. However, even if the door lock control device 10 is configured to actuate the assist function of the door that is actually in the open state to shift to the closed state or actually activate the security function in accordance with the vehicle state signal. Good. Further, the door lock control device 10 may control the notification means according to the vehicle state signal to notify the user of the vehicle of each state in the reserved lock mode.

With such a configuration, in the keyless entry system 1, in the reservation locking mode, the reservation locking mode determination unit 110 (or the door lock control device 10) is based on the position of the corresponding portable key 20 and the open/closed state of each door. Thus, the timing of locking the door provided in the vehicle and the timing of activating the security function are controlled. Further, in the keyless entry system 1, in the reservation lock mode, the reservation lock mode determination unit 110 (or the door lock control device 10) notifies the current operation state to the notification means (the storage mirror motor 60, the lamp 70 (the left lamp 70L). , Right lamp 70R), horn 80, and buzzer 90) to notify the vehicle user.

Here, the operation of the keyless entry system 1 will be described. First, the flow of processing of the door lock control device 10 in the keyless entry system 1 will be described. FIG. 2 is a flowchart showing a flow of operations in the keyless entry system 1 including the door lock control device 10. Further, FIG. 3 is a diagram schematically showing an example of a state of a vehicle in which the keyless entry system 1 including the door lock control device 10 is operating. In the following description of the operation of the keyless entry system 1, the state of the vehicle 100 shown in FIG. 3 will be referred to as appropriate. In the following description, when the driver side rear slide door PSDDR is in the open state, the driver DR of the vehicle 100 operates the external door lock switch 30 to issue an instruction to lock the door, and the door lock control device 10 makes a reservation. The operation of the keyless entry system 1 when it is determined to lock the door in the lock mode will be described. Note that the operation of the keyless entry system 1 when the driver DR of the vehicle 100 operates the portable key 20 to issue an instruction to lock the door, the operation of the external door lock switch 30 is performed by a door lock button provided on the portable key 20. The operation of the keyless entry system 1 can be easily replaced only by replacing the operation.

When the driver DR of the vehicle 100 dismounts and closes the driver's seat door FRDR, the vehicle 100 has the driver's seat side rear slide door PSDDR in the open state, and the other doors (driver's seat door FRDR, passenger's seat door FRAS, and The passenger side rear slide door PSDAS) is in a closed state (see FIG. 3A). After that, when the driver DR operates the external door lock switch 30 (see (b) of FIG. 3), the external door lock switch 30 outputs an operation signal LOCK-SW to the door lock control device 10 (step S1). Accordingly, the door lock control device 10 determines that the operation signal LOCK-SW output from the external door lock switch 30 is an instruction to lock the door, and determines whether the portable key 20 is outside the vehicle. (Step S11). For example, when the keyless entry receiver 101 receives the wireless signal KYE-SIG transmitted by the corresponding portable key 20, the door lock control device 10 recognizes and recognizes the position of the portable key 20 based on the reception state. It is determined whether the portable key 20 is outside the vehicle based on the position.

When it is determined in step S11 that the portable key 20 is not outside the vehicle, that is, the portable key 20 is inside the vehicle, the door lock control device 10 ends the process without locking the door.

On the other hand, when it is determined in step S11 that the portable key 20 is outside the vehicle, the door lock control device 10 shifts to the process of the reserved lock mode, locks all the doors, and then reserves the lock mode determination unit 110. Is activated (step S12) (see (c) of FIG. 3). In step S12, the door lock control device 10 notifies the driver DR of the vehicle 100 and other users that the reservation lock mode determination unit 110 has been activated by setting all the doors in the locked state. You may.

The reservation locking mode determination unit 110 determines whether or not the driver side rear slide door PSDDR is closed (step S21). The reservation locking mode determination unit 110 determines, for example, whether or not the door state signal PSDDDR-SW output from the driver side rear slide door switch 43 indicates a closed state, and thus the driver side rear slide door PSDDR. Determines whether is a closed door.

In step S21, when it is determined that the driver side rear slide door PSDDR is not closed, that is, the driver side rear slide door PSDDR remains in the open state, the reservation locking mode determination unit 110 causes the driver side rear slide. The assist function of the door PSDDR is operated to shift to the closed state (step S22) (see (d) of FIG. 3). At this time, the reservation locking mode determination unit 110 waits until the driver of the vehicle 100 gives a trigger for shifting the closed state of the driver side rear slide door PSDDR in step S22, for example. The assist function may be activated when a trigger is given. Thereby, the user of the vehicle 100 can shift the driver's seat side rear slide door PSDDR to the closed state after unloading the luggage loaded in the vehicle 100.

When it is determined in step S21 that the driver's seat side rear slide door PSDDR is not closed, the reservation locking mode determination unit 110 outputs a vehicle state signal indicating that the driver's seat side rear slide door PSDDR is in the open state. The door lock control device 10 may actually operate the assist function of the driver's seat side rear slide door PSDDR in accordance with the vehicle state signal output from the reservation locking mode determination unit 110 to shift to the closed state. ..

After that, the reservation locking mode determination unit 110 notifies the user of the vehicle 100 that the driver's seat side rear slide door PSDDR is moved to the closed state by using the notification means (for example, the sound of the horn 80 or the buzzer 90 is set to 1). (Step S23) (see (d) of FIG. 3). Then, the reservation/locking mode determination unit 110 returns the process to step S21. In addition, in step S23, the reservation locking mode determination unit 110 outputs a vehicle state signal indicating that the driver's seat side rear slide door PSDDR has been moved to the closed state to the user of the vehicle 100, and the door lock control device 10 causes the reservation. The notification means may be actually controlled according to the vehicle state signal output from the lock mode determination unit 110 to notify that the driver side rear slide door PSDDDR has been shifted to the closed state. As a result, the user of the vehicle 100 shifts the driver side rear slide door PSDDR to the closed state by the notification in step S23, and from now on, all the doors of the vehicle 100 are automatically closed and the security function is activated. I can know. For this reason, the user of the vehicle 100 manually operates the driver's seat rear part even if the driver's seat side rear slide door PSDDR stops operating for some reason before being completely closed after being notified. The sliding door PSDDDR can be closed.

On the other hand, when it is determined in step S21 that the driver's seat side rear slide door PSDDR is closed, that is, the driver's seat side rear slide door PSDDR is in the closed state, the reservation locking mode determination unit 110 closes all the doors. It is determined whether or not it is in the state (step S31). The reservation locking mode determination unit 110, for example, the door status signal FRDR-SW output from the driver's seat door switch 41, the door status signal FRAS-SW output from the passenger's seat door switch 42, and the driver's side rear slide door switch 43. By determining whether or not all of the door status signal PSDDDR-SW output from the vehicle and the door status signal PSDAS-SW output from the passenger side rear slide door switch 44 represent a closed status, all the doors It is determined whether or not is closed.

When it is determined in step S31 that all the doors are not in the closed state, that is, one of the doors is in the open state, the reservation locking mode determination unit 110 sets all the doors in the unlocked state and then executes the process. Stop. In step S31, the reservation lock mode determination unit 110 outputs a vehicle state signal indicating that one of the doors is open, and the door lock control device 10 outputs the vehicle output from the reservation lock mode determination unit 110. The reservation locking mode may be terminated and the reservation locking mode determination unit 110 may be stopped after the doors are actually unlocked in response to the status signal.

On the other hand, when it is determined in step S31 that all the doors are closed, the reservation locking mode determination unit 110 determines whether or not the portable key 20 is outside the vehicle (step S32) ((e in FIG. 3). )reference). When the keyless entry receiver 101 receives the wireless signal KYE-SIG transmitted by the corresponding portable key 20, the reservation locking mode determination unit 110 recognizes the position of the portable key 20 based on the reception state, It is determined whether the portable key 20 is outside the vehicle based on the recognized position.

When it is determined in step S32 that the portable key 20 is not outside the vehicle, that is, the portable key 20 is inside the vehicle, the reservation locking mode determination unit 110 stops the process. In step S32, the reservation lock mode determination unit 110 outputs a vehicle status signal indicating that the portable key 20 is in the vehicle, and the door lock control device 10 outputs the vehicle status signal output from the reservation lock mode determination unit 110. Accordingly, the reserved lock mode may be terminated and the reserved lock mode determination unit 110 may be stopped.

On the other hand, when it is determined in step S32 that the portable key 20 is outside the vehicle, the reservation/locking mode determination unit 110 notifies the user of the vehicle 100 that the security function is to be activated, using a notification means (for example, a left lamp). 70L and the right lamp 70R blink the hazard once and sound the horn 80 and the buzzer 90 once (step S33) (see (e) in FIG. 3). In addition, in step S32, the reservation locking mode determination unit 110 outputs a vehicle state signal indicating that the security function is activated, and the door lock control device 10 responds to the vehicle state signal output from the reservation locking mode determination unit 110. Then, the notification means may be actually controlled to notify that the security function is activated.

Then, the reservation/locking mode determination unit 110 actually activates the security function and stops the processing (step S41). In step S41, the reservation lock mode determination unit 110 outputs a vehicle state signal indicating that the security function is actually activated, and the door lock control device 10 outputs the vehicle state signal output from the reservation lock mode determination unit 110. According to the above, the security function may be actually activated to end the reserved lock mode and the reserved lock mode determination unit 110 may be stopped. In addition, the reservation locking mode determination unit 110 (or the door lock control device 10), after activating the security function, sets the retractable side mirror to the retracted state by, for example, the retractable mirror motor 60, and actually activates the security function. The user of the vehicle 100 may be notified of the activation.

Next, the operation timing of the keyless entry system 1 will be described. FIG. 4 is a timing chart showing an example of operation timing in the keyless entry system 1 including the door lock control device 10. In FIG. 4, each door status signal (door status signal FRDR-SW, door status signal FRAS-SW, door status signal PSDDR-SW, and door status signal PSDAS-SW) output by the door switch 40 and an operation signal are shown. LOCK-SW is shown. In addition, FIG. 4 shows a control signal output from the reserved lock mode determination unit 110 (or the door lock control device 10) to the door lock motor 50 that operates the mechanical mechanism for locking installed in each door. There is. More specifically, the control signal FRDR-AC output to the door lock motor 50 installed in the driver's door FRDR, the control signal FRAS-AC output to the door lock motor 50 installed in the passenger door FRAS, the driver's seat The control signal PSDDR-AC output to the door lock motor 50 installed in the side rear slide door PSDDR and the control signal PSDAS-AC output to the door lock motor 50 installed in the passenger side rear slide door PSDAS are shown. .. Further, in FIG. 4, the reservation/locking mode determination unit 110 (or the door lock control device 10) retrieves (recognizes) the position of the portable key 20, the timing of notifying the current state using the notifying means, the vehicle The timing of changing the control state of 100 is shown.

It should be noted that in FIG. 4, each door status signal has a "High" level when the corresponding door is open (door switch 40 is on), and the door is closed (door switch 40 is off). State), the door state signal is set to the “Low” level. Further, in FIG. 4, it is assumed that the operation signal LOCK-SW becomes the “High” level when the user of the vehicle 100 operates the external door lock switch 30. Further, in FIG. 4, the control signal of each door lock motor 50 is set to "Low" level when the door is unlocked and is set to "High" level when the door is locked.

The driver of the vehicle 100 gets off and closes the driver seat FRDR. Therefore, in FIG. 4, the driver's seat door FRDR, the passenger's seat door FRAS, and the passenger's seat side rear slide door PSDAS are in the closed state, and the driver's seat side rear slide door PSDDR is in the open state. After that, when the driver operates the external door lock switch 30, the external door lock switch 30 outputs the operation signal LOCK-SW at the "High" level to the door lock control device 10 at the timing t1. Thus, the door lock control device 10 determines that the instruction is to lock the door, and searches the position of the portable key 20 from the timing t2.

As a result, when it is searched that the portable key 20 is outside the vehicle, the door lock control device 10 shifts to the control state in the reservation lock mode at timing t3 and activates the reservation lock mode determination unit 110. Then, at the timing t4, the door lock control device 10 sets the control signal output to the door lock motors 50 installed in the respective doors to the “High” level in order to lock all the doors. That is, the door lock control device 10 sets each of the control signal FRDR-AC, the control signal FRAS-AC, the control signal PSDDR-AC, and the control signal PSDAS-AC to the “High” level. As a result, the door lock motor 50 installed on each door operates the locking mechanical mechanism to lock the door.

Further, the reservation locking mode determination unit 110, when activated, determines whether or not there is an open door based on the door state signal corresponding to each door. In FIG. 4, the driver side door FRDR, the passenger side door FRAS, and the passenger side rear slide door PSDAS are in the closed state, and the driver side rear slide door PSDDR is in the open state. Therefore, the reservation/locking mode determination unit 110 determines that the driver side rear slide door PSDDR is in the open state based on the “High” level of the door state signal PSDDDR-SW, and at the timing t5, the driver side rear slide door PSDDR. The assist function is operated to shift to the closed state, and this is notified to the user of the vehicle 100 using the notification means.

After that, the reservation locking mode determination unit 110 determines the open/closed state of the driver side rear slide door PSDDR from the signal level of the door state signal PSDDR-SW, and at timing t6, the driver side rear slide door PSDDR is closed. When it is determined that the time has passed, the position of the portable key 20 is searched from this timing t6.

As a result, the reservation/locking mode determination unit 110 searches (recognizes) that the portable key 20 is outside the vehicle at timing t7. Note that the reservation/locking mode determination unit 110 searches the position of the portable key 20 a plurality of times. FIG. 4 shows a case where the reservation/locking mode determination unit 110 continues to search the position of the portable key 20 five times, that is, six times in total.

Then, at the timing t8, the reservation/locking mode determination unit 110 shifts to the control state in which the security function is activated and activates the security function. After that, the reservation/locking mode determination unit 110 notifies the user of the vehicle 100 at timing t9 that the security function has been activated, using the notification means.

As described above, in the keyless entry system 1, when the portable key 20 is outside the vehicle and at least one door is in the open state, the door lock control device 10 sets all the doors in the locked state and the reserved lock mode. Then, the reservation locking mode determination unit 110 is activated. Further, in the keyless entry system 1, the reservation lock mode determination unit 110 activates the security function when the portable key 20 is outside the vehicle and all doors are closed. As a result, in the keyless entry system 1, even if any of the doors is in the open state, all the doors are in the locked state, so that the resistance of the vehicle 100 against theft can be improved. For this reason, the driver of the vehicle 100 equipped with the keyless entry system 1 is in an open state to unload luggage after himself getting off, or from a safety point of view like a sliding door with an assist function. It takes longer than other doors to be closed, even if the doors are open, there is no need to wait for those doors to close before locking them. It is possible to leave the vehicle 100 immediately after getting off. Further, in the vehicle 100 equipped with the keyless entry system 1, the security function is activated after all the doors are closed, that is, after the last door is closed, so that the vehicle has the portable key 20. A user of the vehicle 100 without the vehicle can unload luggage or the like from the open door without rushing.

In the above description, the case where only the driver's seat side rear slide door PSDDR is in the open state has been described. However, as described above, in the keyless entry system 1, the door lock control device 10 puts all the doors into the locked state even if any of the doors is in the opened state, and the reserved locking mode determination unit 110 causes all the doors to be in the locked state. The security function is activated after is closed. The operation of the keyless entry system 1 when the doors other than the driver's seat side rear slide door PSDDR are also open will be described below. Even if the doors other than the driver's seat side rear slide door PSDDR are in the open state, the operation flow and the operation timing of the keyless entry system 1 are as follows when only the driver's seat side rear slide door PSDDR is in the open state. Can be easily considered based on the operation flow and the operation timing. Therefore, a detailed description of the operation flow and the operation timing of the keyless entry system 1 when doors other than the driver's seat side rear slide door PSDDR are in the open state is omitted, and an example of the state of the vehicle 100 is used, The operation of the keyless entry system 1 when the doors other than the driver side rear slide door PSDDR are in the open state will be described.

FIG. 5 is a diagram schematically showing another example of the state of the vehicle in which the keyless entry system 1 including the door lock control device 10 is operating. FIG. 5 schematically shows a state of the vehicle 100 when the keyless entry system 1 is operating when the passenger side door FRAS is also in the open state in addition to the driver side rear slide door PSDDR.

Along with the driver DR of the vehicle 100, the passenger AS who was in the passenger seat also gets off. However, when the driver DR closes the driver's seat door FRDR, the passenger AS is in a state in which the passenger's seat door FRAS is not closed because, for example, the luggage is unloaded. That is, in the vehicle 100, the passenger door FRAS and the driver side rear slide door PSDDR are in the open state, and the other doors (the driver seat FRDR and the passenger side rear slide door PSDAS) are in the closed state (Fig. 5 (a)). After that, when the driver DR operates the external door lock switch 30, the door lock control device 10 activates the reserved lock mode determination unit 110 after locking all the doors (see (b) of FIG. 5 ). At this time as well, the passenger seat door FRAS is in the open state.

After that, the reservation locking mode determination unit 110 activates the assist function of the driver side rear slide door PSDDR and shifts the driver side rear slide door PSDDR to the closed state. At this time, the passenger seat door FRAS is open. Therefore, the reserved lock mode determination unit 110 does not notify the user of the vehicle 100, particularly the driver DR, of this even if the driver side rear slide door PSDDR is moved to the closed state (see (c) of FIG. 5). .. As a result, the user of the vehicle 100 (particularly the driver DR) can know that the passenger seat door FRAS is open.

Thereafter, the passenger AS closes the passenger door FRAS. At this time, if the driver's seat side rear slide door PSDDR is not in the closed state, the reservation locking mode determination unit 110 allows the user of the vehicle 100 (especially the driver DR) to close the driver's seat side rear slide door PSDDR. You may notify that it is in the process of shifting to (see (d) of FIG. 5). After that, the reservation locking mode determination unit 110 can determine that all the doors are in the closed state when the driver side rear slide door PSDDR is in the closed state. In addition, when the passenger AS closes the passenger seat FRAS after the driver's seat side rear slide door PSDDR is closed, the reservation locking mode determination unit 110 causes the passenger seat FRAS to be closed. It is possible to determine that all the doors are closed.

After that, when the reserved lock mode determination unit 110 determines that the portable key 20 is outside the vehicle, the reservation lock mode determination unit 110 activates the security function of the vehicle 100 and notifies the user of the vehicle 100, particularly the driver DR of this (see ((5 in FIG. 5). See e)).
