JP5177813B2 - Control device for engine start system and engine start system using the same - Google Patents

Description

  The present invention relates to a control device for an engine start system and an engine start system using the same.

  For example, there is an engine starter (also referred to as an “engine starter”) that starts an engine by remote control (remote control) as in the invention disclosed in Patent Document 1 or the like. In this engine starting device, an in-vehicle device that receives a signal from a portable device (remote control) starts the engine by imitating the movement of a key cylinder by an engine key.

  On the other hand, there are various types of car burglar alarm devices (security devices), and as they are called manufacturer options, etc., a device incorporating a burglar alarm device prepared for the vehicle type when it is purchased is manufactured and delivered. In some cases, a user of an automobile that does not have a burglar alarm device purchases various burglar alarm devices and attaches them later. This burglar alarm device installs a vibration sensor and other sensors in the car and detects when a door is opened, the ignition is turned on (engine starts), or a person has entered the car interior during alarm monitoring. Some alarm devices, such as sounding a buzzer or turning on a lamp, are expected to run away without being stolen.

  The set (arm) and reset (disarm) of the burglar alarm device may be performed using a dedicated remote controller (portable device). In particular, in a so-called burglar alarm device such as a manufacturer auto option, a door key ( There are some which perform setting / resetting in synchronization with the lock by the operation of the door's seek killer with the mechanical key.

Furthermore, by pressing an operation button (locking button / unlocking button) provided on the portable device, or by pressing a locking button installed on the vehicle door while holding the portable device, the door of the automobile There is a keyless entry that unlocks / locks. As with the burglar alarm device, the keyless entry includes a genuine one such as a manufacturer option and a retrofit type. In particular, in the case of a genuine keyless entry, there is a case in which a genuine burglar alarm device is set in conjunction with a locking operation by the keyless entry and shifts to a warning state.
JP 2004-36505 A

  By the way, if the engine is started (ignition is turned on) by a remote engine starter (engine starter) when the theft alarm device is in the arm state (warning state), the burglar alarm device will turn on the illegal ignition or the engine. There is a problem that a vibration or a moving body due to starting is detected and an alarm is issued. This is because the engine start based on the engine starter is based on an operation from a legitimate user (driver or the like), and it is not necessary to issue an alarm, and it is not preferable that an alarm is issued.

  If a burglar alarm device is installed as a manufacturer option and the engine starter is also installed as a manufacturer option, the control information can be used mutually. When the engine is started by the starter, it is possible to take measures such as not to issue an alarm even in a warning state. However, in the case of a retrofit engine starter, it is difficult to work with a genuine burglar alarm device. As a result, in order to suppress alarms due to the above situation, the user must reset the theft alarm device in advance and then operate the portable device of the engine start device to perform the engine start operation. Work becomes complicated.

  Accordingly, a first object of the present invention is to prevent an alarm of a theft alarm device accompanying an engine start even when an engine start command is received from a portable device. . Furthermore, even if the theft alarm device is under monitoring / warning, it is possible to start the engine by the engine starting device without issuing an alarm by releasing the warning state with a simple operation. Second purpose.

  In order to achieve the above-described object, a control device for an engine start system according to the present invention is (1) a control device in an engine start system for starting an engine of a vehicle by remote operation, and is mounted on the vehicle. A state detection unit for detecting a state of the theft alarm device; and a determination unit for determining permission / non-permission of engine start based on the state detected by the state detection unit, wherein the determination unit includes the state detection unit When the state detected in step 1 is at least a warning state, it is determined that the engine start is not permitted.

  According to the present invention, when the burglar alarm device is in a warning state, the engine start is not permitted, so the engine start processing (signal output for turning the cell motor, etc.) on the actual vehicle is not performed. Therefore, even if a legitimate user operates the portable device and transmits an engine start command when the theft alarm device is in a warning state, the engine is not actually started based on that, so that no alarm is issued.

  (2) In the case of a warning state, a means for outputting an unlock signal for unlocking the door lock may be provided, and the determination means may have a function of permitting engine start after outputting the unlock signal. . In this way, the door lock is unlocked by the output of the unlock signal, and the theft alarm device is also released. Therefore, even if the burglar alarm device is in a warning state, it is switched to a release state, so that no warning is issued even if the engine is started in response to the engine start permission being issued thereafter.

  (3) In a warning state, it comprises means for outputting an unlock signal for unlocking the door lock, and the decision means outputs a lock signal for locking the door lock after outputting the unlock signal. It is good to have the function to output engine and to permit engine starting after that. If it does in this way, in addition to the effect of said (2), since a door lock is locked, it is preferable also in terms of security. Normally, even if a door lock is locked using a non-genuine post-installed keyless entry, the door is not linked to the burglar alarm device and does not shift to a warning state. Therefore, even if the lock signal of the present invention is wired to a genuine electronic device in the same manner as the keyless entry attached later, even if the lock signal is output and the door lock is locked, the burglar alarm device is in the released state. If the engine starts after that, no alarm will be issued.

  (4) When door opening detecting means for detecting opening of the vehicle door is provided, and the determination means detects that the door is opened by the door opening detecting means after outputting the unlock signal. It is preferable to provide a function for disabling engine start. When the door lock is unlocked based on the unlock signal, there is a possibility that the person around the car can open the door. Therefore, when it is detected that the door is opened, it is safer if a function for not permitting / stopping the engine start is provided. The door opening detection means may be provided with various sensors separately, and may be obtained from them, or if there is a genuine sensor or the like mounted on the vehicle, it detects that the door is opened by connecting to it. You may do it.

  (5) The said state detection means is good to extract the information which shows the state of the burglar alarm apparatus transmitted on in-vehicle LAN. Information on the state of the vehicle (genuine electronic device, etc.) is periodically transmitted on the in-vehicle LAN. Therefore, by extracting the information, the state of the burglar alarm device can be recognized.

  (6) When the door lock of the vehicle is in a locked state, the state detecting means determines that the door is in a warning state when the locked state is not performed by a non-genuine keyless entry function. Good. Even if the door lock is locked using a non-genuine keyless entry, the non-linkage and the burglar alarm device will not be in a warning state. Therefore, if the door lock is in a locked state and the locked state is based on a non-genuine keyless entry function, the current burglar alarm device can be said to be in a released state and the engine start can be permitted. On the other hand, if the current locked state is not locked by a non-genuine keyless entry function, the burglar alarm device is likely to be in a warning state, so engine start is not permitted. Of course, in this case, by incorporating the inventions of (2), (3), etc., the burglar alarm device can be released and the engine can be started.

  (7) The state detection unit has a function of determining whether or not the theft alarm device is in alarm, and the determination unit does not start the engine when the state detection unit determines that the alarm is in progress. It is advisable to have a function to allow. Whether or not the alarm is in progress may be determined by acquiring information from the in-vehicle LAN, or may be determined by whether or not the alarm means (horn or hazard lamp) is operating, and other various methods. I can take it.

  (8) An engine start system according to the present invention includes a control device for an engine start system according to any one of (1) to (7), a receiving unit that receives an engine start command from a portable device, and a receiving unit thereof Output means for outputting a signal for starting the engine on condition that the control device permits the engine to start when the engine start command is received by the control unit.

  In the present invention, the control device recognizes the state of the burglar alarm device, and at least in the case of a warning state, the engine start is not permitted. Therefore, in such a case, the engine start command is temporarily received from the portable device. Even if it exists, since the engine does not start, it is possible to prevent the occurrence of a false alarm (unnecessary alarm) of the theft alarm device. Furthermore, even if the burglar alarm device is monitoring / warning, it is equipped with a function to output an unlock signal for unlocking the door lock, so that the alarm is not issued by releasing the warning state. The engine can be started.

  FIG. 1 shows the configuration of the entire system to which a preferred embodiment of the present invention is applied. The engine start system 10 according to the present embodiment is mounted on a vehicle on which the automobile burglar alarm device 1 is mounted, and includes an engine starter body 11 and an adapter unit 12 constituting a control device.

  First, the configuration of a genuine electronic device or the like mounted on a vehicle on which the engine start system 10 of this embodiment is mounted will be described. The burglar alarm device 1 is a genuine one that can be attached by a manufacturer option, a dealer option, or the like. The theft alarm device 1 switches the state of setting (arm) to a warning state of theft alert and resetting to a released state (disarm) according to appropriate conditions.

  Specifically, the warning state is set when the door lock is locked with a genuine key, that is, when the mechanical key is locked and when the lock is performed with a genuine keyless entry. Even when the door is locked, the door can be locked by operating the door lock knob in the passenger compartment or the central door lock switch 6 installed on the driver's seat, or pulling the door handle outside the passenger compartment. When the door is closed while the lock knob or the central door lock switch 6 is operated and locked, it is not set as a warning. Even when the door lock is locked using a keyless entry that is retrofitted (not genuine), the drive motor linked to the central door lock switch 6 is energized in the same manner as the locking operation by the central door lock switch 6. Will not be set to vigilance.

  On the other hand, the reset that releases the alert state and shifts to the released state is performed when the door lock is unlocked. Switching to the unlocked state is performed when the door lock is unlocked with a genuine key, that is, when the mechanical key is unlocked and when unlocking is performed with a genuine keyless entry. Even if the door is unlocked by the central door lock switch 6 in the vehicle compartment, the unlocked state does not occur. However, there is a switch wiring linked to the burglar alarm device 1, and the burglar alarm device 1 can be released by connecting an unlock signal to the wiring of the switch. Therefore, even if the door lock is unlocked using a keyless entry that is retrofitted (not a genuine product), the unlock signal output from the keyless entry is reset by connecting it to the associated switch, and the warning is released. Can be done.

  The determination as to whether or not the door lock is locked / unlocked with a genuine key may be made, for example, by notifying the theft alarm device 1 when the operation is performed, If the door lock state switch 3 for detecting the state of the door lock is interlocked with the operation, the burglar alarm device 1 can make a determination based on the signal from the door lock state switch 3.

  The burglar alarm device 1 causes the hazard lamp 4 to blink in a predetermined pattern, for example, when the set / reset state is switched. The predetermined pattern is made different between “set” and “reset”. Thereby, the user can recognize that the theft alarm device 1 has been warned / released. Further, when an abnormality is detected during warning, the theft alarm device 1 issues an alarm by, for example, sounding the horn 5 or blinking the hazard lamp 4 to notify an abnormality to a person in the vicinity,・ I threaten the criminal who tried to mischief.

  The in-vehicle LAN 2 is wired in the vehicle for transmitting and receiving information between various electronic devices (ECUs) installed in the vehicle, and various information about the vehicle is transmitted. The genuine burglar alarm device 1 is also connected to the in-vehicle LAN 2, and information on the current state (warning state / release state / alarming) is also periodically transmitted to the in-vehicle LAN 2. Information (signal pattern) regarding the current state of the burglar alarm device 1 transmitted to the in-vehicle LAN 2 varies depending on the vehicle type. In addition, the communication protocol in the in-vehicle LAN 2 may differ depending on the vehicle type.

  On the other hand, the engine start system 10 shown in FIG. 1 shows a hardware configuration common to the embodiments described below. That is, the engine start system 10 according to the present embodiment, when receiving an engine start command from the portable device 13, in addition to the function of starting the engine by executing a predetermined procedure, It has a retrofit keyless entry function that unlocks / locks the door lock according to the lock command.

  The engine starter body 11 and the adapter unit 12 are connected by a first communication cable 15a and a second communication cable 15b. The adapter unit 12 is connected to the in-vehicle LAN 2 via the third communication cable 15c and is connected to the central door lock switch 6 via the fourth communication cable 15d. By operating the central door lock switch 6, the drive motor linked to the door lock rotates and locks / unlocks. Strictly speaking, the central door lock switch 6 includes a central door lock switch (switch for operating the drive motor) that is not linked to the burglar alarm device 1 and a central door lock switch that is linked to the burglar alarm device 1.

  The first communication cable 15 a is a cable for sending a lock signal / unlock signal from the engine starter body 11 to the adapter unit 12. That is, the first communication cable 15a is for realizing a keyless entry function. When the engine starter body 11 receives an unlocking / locking command from the portable device 13, an unlock signal or a lock signal corresponding to the unlocking / locking signal is received. Output. As will be described later, the adapter unit 12 that has received the lock signal / unlock signal via the first communication cable 15a sends the lock signal / unlock signal to the actual vehicle to perform locking / unlocking processing. . If attention is paid only to the keyless entry function, the first communication cable 15a connected to the engine starter main body 11 may be directly connected to the centralized door lock switch 6 or the like of the vehicle to perform locking / unlocking processing. . Conversely, when there is no keyless entry function, the first communication cable 15a may be omitted. In the present embodiment, the first communication cable 15a uses a separate cable for each signal, so that the adapter unit 12 can be notified by a simple Low / High signal. Of course, the 1st communication cable 15a can also be comprised by one.

  The second communication cable 15 b is a cable that performs bidirectional communication between the engine starter body 11 and the adapter unit 12. Via this second communication cable 15b, the unit is authenticated between the engine starter body 11 and the adapter unit 12, the engine starter body 11 sends an inquiry for permission to start the engine to the adapter unit 12, The adapter unit 12 sends permission / non-permission of engine start as a response to the inquiry.

  The third communication cable 15c connects the adapter unit 12 and the in-vehicle LAN 2, and the adapter unit 12 indicates information transmitted on the in-vehicle LAN 2 (the state of the burglar alarm device 1 (warning state / release state / alarming)). Information).

  The fourth communication cable 15d is a cable for the adapter unit 12 to output a lock signal and an unlock signal to the genuine electronic device of the vehicle. As described above, the fourth communication cable 15d is connected to the central door lock switch 6 in the present embodiment. doing. The cable for the lock signal is connected only to the central door lock switch 6 that is not linked to the burglar alarm device 1, and the cable for the unlock signal is connected to a switch that is linked to the burglar alarm device 1. As a result, when the unlock signal is output from the adapter unit 12, the burglar alarm device 1 enters a release state, but when the lock signal is output from the adapter unit 12, the burglar alarm device 1 does not enter a warning state. Further, in the present embodiment, the engine unit can be started without issuing an alarm even in a warning state when an engine start command described later is received. Therefore, the adapter unit 12 is provided with a fourth communication cable 15d. It was. In order to solve the problem at the time of starting the engine in this way, the adapter unit 12 is connected to the genuine electronic device on the vehicle side via the fourth communication cable 15d to directly perform the locking / unlocking operation. The starter body 11 and the adapter unit 12 are connected by the first communication cable 15a, and the engine starter body 11 executes the locking / unlocking instruction received from the portable device 13 via the adapter unit 12, but this warning state If the function for enabling the engine to start is not provided, the end of the first communication cable 15a may be connected to the vehicle-side genuine electronic device without providing the fourth communication cable 15d.

  The communication cables are grouped together in an appropriate group by a harness and connected to a predetermined device or the like. An example is shown in FIG. In this example, the 1st communication cable 15a, the 2nd communication cable 15b, and the 4th communication cable 15d comprise one harness, and are connected to the adapter unit 12 by the common connector C1. The third communication cable 15c is incorporated in another harness. This harness is interrupted and connected to the in-vehicle LAN 2 using the connection interrupt connectors C2 and C3. That is, the in-vehicle LAN 2 is extended and connected to the inside of the vehicle while connecting the connectors at appropriate positions. Therefore, the in-vehicle LAN 2 connector is removed, and the connection interrupt connectors C2 and C3 are attached to make the in-vehicle LAN 2 conductive, and a predetermined signal line is branched and connected to the adapter unit 12 as the third communication cable 15c.

  Next, a configuration that is a premise of the function of starting the engine will be described. The engine starter body 11 can be shared regardless of the type of vehicle or the option (presence / absence of a burglar alarm device / presence / absence of an immobilizer system) installed in the automobile. Therefore, when the engine starter body 11 receives an engine start command from the portable device 13, it tries communication with the adapter unit 12 via the second communication cable 15b, and if communication is established, the engine starter from the adapter unit 12 starts. The engine start process is performed after the permission notification. On the other hand, if the communication is not established, it is determined that the adapter unit 12 does not exist, and the engine start process is performed as it is.

  The engine start process is as follows. Although not shown in the drawings, the cell motor of the automobile is connected to the battery via a magnet switch and an ignition key switch, and usually the engine is controlled by operating this key switch with a key. As is well known, the ignition key switch has a position where power supply to each part is stopped (OFF), an accessory position (ACC) where various electrical components can be driven, and an ignition circuit which supplies power to idling. There are an ignition position (IG) for continuing the operation and a start position (ST) for starting the engine by energizing the cell motor by energizing the magnet switch when the engine is stopped. The engine starter body 11 operates the built-in relay drive circuit in an appropriate order, and energizes the cell motor and the battery, thereby creating a state in which the ignition key switch is shifted from ACC to IG in a pseudo manner. To drive.

  The burglar alarm device 1 determines that an abnormality has occurred and issues an alarm when, for example, the ignition is turned on in the alert state. Therefore, when the engine start system 10 of the present embodiment receives an engine start command from the portable device 13, it determines whether the theft alarm device 1 is in a warning state, and does not perform an engine start operation in the case of a warning state. The engine starts when the warning is released. Thus, the engine start process is not performed by turning the cell motor through the ignition ON in a warning state, and the burglar alarm device 1 is prevented from issuing an alarm when the engine is started.

  Furthermore, in this embodiment, when in the alert state, a function for canceling the alert state and performing engine start processing thereafter is provided. Thereby, regardless of whether or not the burglar alarm device 1 is in a warning state, when an engine start command is received from the portable device 13, the engine start operation can be finally performed and the burglar alarm device associated therewith. The occurrence of alarm 1 can also be suppressed. Even if the alarm state by the theft alarm device 1 is canceled, the authorized user (car owner, driver, etc.) operates the portable device 13 and issues an engine start command. There is no problem because it can be predicted that the user will move to the car. Furthermore, if the engine is to be started by the engine starting system 10, the user needs to perform processing for switching the warning state of the burglar alarm device 1 to the release state once before operating the portable device 13. However, by using the engine start system 10 of the present embodiment, the process for setting the release state can be automatically performed, and the user does not need to perform the process, so that convenience is improved.

  In the first embodiment, in order to perform the above processing, a signal indicating the state (warning state / release state / alarming) of the burglar alarm device 1 transmitted on the in-vehicle LAN 2 is read to determine the current state. did. As described above, since the signal transmitted on the in-vehicle LAN 2 varies depending on the vehicle type and the like, in this embodiment, the adapter unit 12 for the vehicle type to be attached is prepared separately from the engine starter body 11, and an actual burglar alarm device is provided. The adapter unit 12 determines whether or not the engine can be started, including the determination of the state 1 (warning state / release state / alarming).

  Thereby, the engine starter main body 11 can be shared by incorporating a common process / function independent of the vehicle type. That is, when the user intends to install the engine start system 10 in a vehicle equipped with the genuine burglar alarm device 1, the user prepares a common engine starter body 11 and an adapter unit 12 corresponding to the vehicle type, and communicates appropriately. The cable is used to connect the engine starter body 11, the adapter unit 12, and genuine electronic equipment of the vehicle (wireless LAN 2, central door lock switch, etc.). Further, when the vehicle is changed, a newly acquired adapter unit 12 for the vehicle can be purchased and used in combination with the engine starter body 11 that has already been used. Furthermore, the engine starter main body 11 communicates with the adapter unit 12 and can know its existence by establishing communication. Therefore, if the adapter unit 12 is not connected, the engine starter body 11 recognizes that it is installed alone, and if it receives an engine start command from the portable device 13, the state of the burglar alarm device 1 The engine start operation is performed without confirming the above. As described above, the engine starter main body 11 can be used even if it is not mounted with a normal burglar alarm device or does not cooperate with the state of the burglar alarm device 1, and various vehicle types can be combined with an appropriate adapter unit 12. It can also be used as a link with the state of the genuine burglar alarm device 1 in FIG. Since the engine starter body 11 can be shared in this way, the cost can be reduced. Of course, in the present invention, it is not essential to separate the engine starter body 11 and the adapter unit 12 as described above, and the function of the adapter unit 12 may be incorporated into the engine starter body 11 and integrated.

  In the configuration described above, the adapter unit 12 of the present embodiment has a function of executing the processing of the flowchart shown in FIG. That is, when the engine starter body 11 receives an engine start command from the portable device 13, the engine starter body 11 establishes communication with the adapter unit 12 via the second communication cable 15b and inquires about engine start permission. Therefore, the adapter unit 12 receiving it starts the flowchart shown in FIG. First, the adapter unit 12 monitors the in-vehicle LAN 2 via the third communication cable 15c, and determines the state (warning / release / warning) of the theft alarm device 1 (S1).

  And when the state of the theft alarm device 1 is a cancellation | release state, the adapter unit 12 notifies engine start permission with respect to the engine starter main body 11 via the 2nd communication cable 15b (S2). Moreover, when the state of the theft alarm device 1 is alarming, the adapter unit 12 notifies the engine starter body 11 of the engine starter disapproval via the second communication cable 15b (S3).

  Further, when the theft alarm device 1 is in a warning state, the adapter unit 12 is connected to a central door lock switch 6 (a switch interlocked with the theft alarm device 1) which is a genuine electronic device of the vehicle via the fourth communication cable 15d. On the other hand, an unlock signal is output (S4). As a result, the door lock is unlocked. As described above, the theft alarm device 1 switches from the alert state to the released state by unlocking the door lock. In this state, the door lock of the automobile remains unlocked, which is not preferable from the viewpoint of security. Therefore, the adapter unit 12 outputs the door lock signal after outputting the unlock signal (S5). As a result, the door lock is unlocked, but since this locking process is not a lock with a genuine keyless entry, the burglar alarm device 1 remains in the released state. Thereafter, the adapter unit 12 notifies the engine starter body 11 of permission to start the engine (S6).

  The engine starter main body 11 executes the engine start process or does not perform the engine start process in accordance with the notification from the adapter unit 12. As the process step S4 is executed, the burglar alarm device 1 is in a released state, and even if the process step S5 is executed, the released state continues. Therefore, even if the engine start process is performed, The theft alarm device 1 does not issue an alarm.

  Finally, the engine starter body 11 returns the execution result (engine start / not start, etc.) to the portable device 13 and ends the series of processes. The notification to the portable device 13 is a notification using hearing such as voice or buzzer sound, or when the portable device 13 has a display unit, the display unit displays visual information such as character information and icons. Notifications that have been used can be made.

  Further, by providing a sensor for detecting the opening / closing of the door or acquiring information on the opening of the door flowing through the in-vehicle LAN 2, the unlocking is performed once by executing the processing step S4, and the locking process of the processing step S5 is executed. When the door opening is detected until the end of the period, it is preferable to provide a function of notifying that engine start is not permitted.

  In the first embodiment, as the state of the burglar alarm device 1, in addition to the warning state and the release state, the three states in the alarm are identified and corresponded to each other. One state may be identified. In that case, for example, it can be realized by a function of executing a flowchart without processing step S3 from the flowchart shown in FIG. Assuming that the branch determination in the processing step S1 recognizes “warning state” and “released state”, if it is “alarming”, since it cannot be recognized, it will be in a waiting state. When the engine start process is not performed or when the state cannot be recognized for a certain period of time, an error can be generated and the result (error) can be sent to the portable device. In any case, since the user who issued the engine start command on the portable device is in the vicinity of the vehicle (the range in which the radio wave from the portable device reaches the vehicle (engine starter body 11)) in the case of an alarm, There is no problem because it is recognized that the alarm is sounding and goes to the place where the car is installed, or the engine start / stop command is issued after hearing the alarm.

  Further, as shown in FIG. 4, the adapter unit 12 determines whether or not it is in a warning state (alarming) (S1 ′). A notification may be issued (S2), and if the branch determination result is Yes, an engine start non-permission notification may be issued (S3).

  FIG. 5 shows a second embodiment of the present invention. In the present embodiment, it is assumed that a retrofit keyless entry function is provided. And the adapter unit 12 is provided with the memory | storage part which memorize | stores the log | history of the door lock control signal by a keyless entry function. Note that this storage unit only needs to store at least the most recent door lock, and therefore may be a “1/0” flag. The history of the door lock control signal is used to identify whether or not the last door lock of the automobile is due to the keyless entry function of the present embodiment. Therefore, even if the door is locked by the keyless entry function in the past, the door lock control signal is not output when the previous door lock is performed by a genuine key operation. This history information (flag) is cleared, for example, when the door lock is unlocked and cleared (no door lock control signal output history: flag 0), and the door lock is locked by the keyless entry function of this embodiment. When (lock signal is output), it can be realized by switching to the output history of the door lock control signal (flag 1).

  Under the above assumption, when the engine starter body 11 receives an engine start command from the portable device 13, it establishes communication with the adapter unit 12 via the second communication cable 15b and permits engine start. The adapter unit 12 that has received the inquiry starts the flowchart shown in FIG. First, the adapter unit 12 confirms the door lock state (S11). For example, the adapter unit 12 can be connected to the door lock state switch 3 mounted on the vehicle and recognized from the state of the switch 3 or collected from various other sensors and switches. When the door is locked (locked) (Yes in S11), the adapter unit 12 confirms whether there is a history of door lock control output (S12). That is, it is determined whether the currently locked state is locked by a lock signal (door lock control signal) by the keyless entry function.

  Then, when locked by the door lock control signal by the keyless entry function (Yes in S12), the burglar alarm device 1 remains in the released state, so the adapter unit 12 issues an engine start permission notification (S13). . On the other hand, if the door is not locked by the door lock control signal from the keyless entry function (No in S12), the adapter unit 12 may notify the engine start non-permission because there is a possibility that the theft alarm device 1 is on alert. Issue (S14).

  When the door is not locked (No in S11), the adapter unit 12 determines whether the theft alarm device 1 is in alarm (S15). This determination can be made based on, for example, confirming the state of the horn 5 or the hazard signal of the vehicle. In other words, the alarm by the burglar alarm device 1 is that the horn 5 is leveled or the hazard lamp 4 is blinked. Therefore, when the horn 5 is ringing or the hazard signal is activated (ON / OFF). If it is, it can be determined that the alarm is in progress. This is because a legitimate user is trying to start the engine with the engine starter main body 11 and is not in the car, and the horn 5 or the hazard lamp 4 does not blink by a legitimate operation. It is.

  When the alarm is not in effect, the adapter unit 12 notifies the engine start permission (S13), and when the alarm is in effect, the adapter unit 12 notifies the engine start non-permission (S16). Even if the engine start process is performed in the unlocked state, even if the engine is started by the engine starter body 11, the automobile cannot be run as it is (the engine is temporarily stopped and started by a normal key operation or the like). So there is no problem. Finally, the engine starter body 11 returns the execution result (engine start / not start, etc.) to the portable device 13 and ends the series of processes.

  Note that the present invention may be realized simply by a function including the processing steps S12, S13, and S14. Further, when the processing step S11 is added and the vehicle is unlocked, a predetermined processing (engine start permission) is performed. / Non-permission). Other configurations and operational effects are the same as those of the above-described embodiments and modifications, and thus detailed description thereof is omitted.

  FIG. 6 shows a third embodiment. This embodiment is based on the second embodiment, and when the theft alarm device 1 is on alert as in the first embodiment, the alert is released and the engine can be started. That is, as apparent from a comparison between FIG. 5 and FIG. 6, if the branch determination in processing step S12 is No (there is no door lock control output history), the possibility of a warning state (alarming) is high. The adapter unit 12 determines whether an alarm is in progress. This determination can be made based on whether or not the horn 5 is ringing as in the processing step S15. If the alarm is being issued (Yes in S25), the engine start disapproval is notified (S16). On the other hand, when there is no alarm, the possibility of a warning state is high, so the adapter unit 12 is connected to the central door lock switch 6 (the burglar alarm device 1 in conjunction with the genuine electronic device of the vehicle) via the fourth communication cable 15d. The unlock signal is output to the switch (S27). As a result, the door lock is unlocked. As described above, the theft alarm device 1 is switched from the alert state to the released state by unlocking the door lock. Next, the adapter unit 12 outputs a door lock signal using the fourth communication cable 15d (S28). As a result, the door lock is unlocked, but since this locking process is not a lock with a genuine keyless entry, the burglar alarm device 1 remains in the released state. Thereafter, the adapter unit 12 notifies the engine starter body 11 of permission to start the engine (S29). Even if the branching determination in processing step S25 is No, the burglar alarm device 1 may be in a released state, such as when the central door lock switch 6 is operated to lock it. There is no problem because it only returns to the original state. This embodiment is preferable because the probability that the engine start process can be performed is increased. In the present embodiment, it is further preferable to provide a function of disabling engine start when it is detected that the door is opened between unlocking and locking. Other configurations and operational effects are the same as those of the above-described embodiments and modifications, and thus detailed description thereof is omitted.
