  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment of the present invention)
FIG. 1 is a block diagram of the in-vehicle control device according to the first embodiment of the present invention. In FIG. 1, two vehicles 1 are illustrated, and an in-vehicle control device 10 is mounted on each vehicle 1. In addition, when distinguishing each of the two vehicles 1, it describes as the vehicle 1A and the vehicle 1B, and when not distinguishing, it describes as the vehicle 1.

  The in-vehicle control device 10 includes a communication interface 11 that performs wireless communication via an antenna, a storage unit 12 that stores data, an operation reception unit 13 that receives an operation of the owner of the vehicle 1 using a key, and the vehicle 1 is stolen. It is configured to include a warning means 16 for notifying in the case of being performed, and a processor such as a CPU (not shown). The in-vehicle control device 10 includes a monitoring target vehicle confirmation unit 14, a monitoring unit 15, a notification receiving unit 17, and a monitoring cancellation unit 18 that are configured by a module of a program executed by a processor.

  The storage unit 12 stores various data. For example, the monitoring unit identification information for identifying the vehicles to be monitored when the vehicles are monitored with each other, and the own vehicle 1 are identified. Self-identification information is stored.

  In the first embodiment of the present invention, the storage unit 12 of the vehicle 1A stores monitoring target identification information for identifying the vehicle 1B and self-identification information for identifying the vehicle 1A, and the storage unit 12 of the vehicle 1B. The monitoring object identification information for identifying the vehicle 1A and the self-identification information for identifying the vehicle 1B are stored.

  The operation accepting means 13 accepts setting or canceling of the monitoring mode in which the vehicle-mounted control device 10 monitors the vehicle 1 to be monitored by the operation of the owner of the vehicle 1. In the first embodiment of the present invention, the operation accepting means 13 accepts a remote operation of the door lock performed by using the key of the remote control while the engine is stopped as the setting of the monitoring mode, and releases the door lock. Accept as canceling the monitoring mode.

  The monitoring target vehicle confirmation unit 14 confirms whether or not the vehicle 1 indicated by the monitoring target identification information stored in the storage unit 12 is in the vicinity when the operation reception unit 13 receives the setting of the monitoring mode. It has become. For example, as shown in FIG. 2, the monitoring target vehicle confirmation unit 14 of the vehicle 1B includes the self-identification information of the vehicle 1A acquired by wireless communication from the vehicle 1A within the monitorable range of the vehicle 1B via the communication interface 11. It is determined whether or not the monitoring target identification information stored in the storage unit 12 of the vehicle 1B is the same. When the monitoring target vehicle confirmation unit 14 determines that the self-identification information acquired from the partner vehicle and the monitoring target identification information stored in the storage unit 12 are the same, the monitoring target vehicle is in the vicinity. And

  When the monitoring target vehicle confirmation unit 14 confirms that the vehicle to be monitored is in the vicinity, the monitoring unit 15 periodically monitors whether or not the vehicle to be monitored has been stolen. For example, the monitoring unit 15 periodically monitors whether or not the vehicle has been stolen by checking whether there is a change in the distance between the own vehicle and the vehicle to be monitored.

  When the monitoring means 15 receives an electromagnetic wave of a specific frequency radiated from a vehicle to be monitored via the communication interface 11, the monitoring means 15 checks whether there is a change in the intensity of the electromagnetic wave, thereby changing the distance between each other. It may be determined whether or not there is. Further, when the in-vehicle control device 10 has a GPS (Global Positioning System), it may confirm whether or not there is a change in the distance obtained from the position information of the vehicle 1A and the position information of the vehicle 1B. .

  When the monitoring unit 15 determines that the vehicle to be monitored has been stolen, the alarm unit 16 issues an alarm. For example, when alarming, the alarm means 16 may sound a loud sound, emit light, or report to a system such as a security company.

  The notification receiving unit 17 receives a notification that the monitoring mode has been canceled from the vehicle to be monitored via the communication interface 11 and notifies the monitoring cancellation unit 18 of the notification.

  When the operation accepting unit 13 accepts the cancellation of the monitoring mode, the monitoring canceling unit 18 notifies the monitoring unit 15 to cancel the monitoring of the vehicle and informs itself that the monitoring mode has been canceled via the communication interface 11. The vehicle that was monitoring the vehicle is notified.

  When canceling the monitoring of the vehicle, the monitoring canceling means 18 confirms whether or not the order of the vehicles for canceling the monitoring mode follows a specific order. For example, when the specific order is the order opposite to the order of parking, if the monitoring cancellation means 18 is parked in the order of the vehicle 1A and the vehicle 1B, the monitoring mode is set in the order of the vehicle 1B and the vehicle 1A. It is necessary to cancel. Moreover, the monitoring cancellation | release means 18 makes the warning means 16 alarm, when it is going to cancel | release the monitoring of a vehicle, without following a specific order.

  The operation of the in-vehicle control device 10 configured as described above will be described with reference to the drawings. FIG. 3 is a sequence diagram showing an example of processing related to the monitoring mode of the vehicle anti-theft system using the in-vehicle control device 10.

  Before explaining the sequence diagram of FIG. 3, the situation of the vehicle 1A and the vehicle 1B will be described. The vehicle 1A is already in the monitoring mode, the vehicle 1B is not in the monitoring mode, and the positions of the vehicles 1A and 1B are The relationship is as shown in FIG.

  After the engine of the vehicle 1B is stopped, the driver of the vehicle 1B performs an operation for locking the door of the vehicle 1B by a key operation (step S11). The operation accepting means 13 accepts this operation, and the monitored vehicle confirmation means 14 transmits the self-identification information for identifying the own vehicle 1B from the storage means 12 to the vehicle 1A (step S12).

  The monitoring target vehicle confirmation unit 14 of the vehicle 1A receives the self-identification information transmitted from the vehicle 1B (step S13), and transmits the self-identification information for identifying the vehicle 1A from the storage unit 12 to the vehicle 1B. (Step S14).

  The monitoring target vehicle confirmation unit 14 of the vehicle 1B receives the self-identification information transmitted from the vehicle 1A (step S15). The mutual monitoring target vehicle confirmation means 14 determines whether or not the received self-identification information of the other party is the same as the monitoring target identification information stored in the storage means 12, (Step S16).

  When the vehicle to be monitored is in the vicinity, the monitoring unit 15 of the vehicle 1A and the vehicle 1B stores information indicating the distance from the vehicle to be monitored in the storage unit 12 (step S17), and periodically Whether or not the vehicle has been stolen is monitored by checking whether there is a change in the distance between the vehicle and the vehicle to be monitored (step S18).

  As shown in FIG. 4, when there is a change in the distance between the vehicle 1A and the vehicle 1B, it is considered that the vehicle has been stolen, and the alarm means 16 of the vehicle 1A and the vehicle 1B warn each other with an alarm sound or the like. . The alarm means 16 may prevent the engine from starting when alarming.

  Conventionally, even if a stolen vehicle sounds an alarm sound, if it moves far away from the theft site, the owner (or a neighboring person at the theft site) will not notice the alarm sound. In the vehicle anti-theft system according to the embodiment, when the vehicle is stolen, the in-vehicle control devices 10 that are monitoring each other warn by sounding an alarm sound or the like, so that the stolen vehicle moves far away. However, since the vehicle remaining on the site also sounds an alarm sound, the owner (or a neighbor at the site of the theft) can be aware of the vehicle theft.

  Conventionally, even if a stolen vehicle sounds an alarm sound, if the alarm or immobilizer wiring is cut and the alarm sound is stopped, the owner (or a neighboring person at the theft site) Although the alarm sound is not noticed, the vehicle anti-theft system according to the embodiment of the present invention warns when the vehicle is stolen by causing the remaining vehicles on the site that were monitored to sound an alarm sound. Therefore, the owner (or a neighboring person at the theft site) can notice the vehicle theft.

  FIG. 5 is a sequence diagram showing an example of processing related to the monitoring mode for saving power. The same steps as those described in FIG. 3 are denoted by the same reference numerals. As in the case described with reference to FIG. 3, the vehicle 1A is already in the monitoring mode, the vehicle 1B is not in the monitoring mode, and the positional relationship between the vehicle 1A and the vehicle 1B is as shown in FIG.

  At this time, since power consumption efficiency is not always good for supplying power to the vehicle-mounted control device of the vehicle 1A, power is supplied to the vehicle-mounted control device of the vehicle 1A at regular time intervals (for example, every 3 seconds). The monitoring target vehicle confirmation unit 14 determines whether or not information transmitted from another vehicle is received when power is supplied (step S31). If no information is received, for example, 3 seconds or the like The power supply stops at a certain time.

  After the engine of the vehicle 1B is stopped, the driver of the vehicle 1B performs an operation for locking the door of the vehicle 1B by a key operation (step S11). Here, the monitoring target vehicle confirmation unit 14 of the vehicle 1B transmits the self-identification information for identifying the own vehicle 1B from the storage unit 12 to the vehicle 1A in a certain time or more (for example, 3 seconds or more) (step) S32). The monitoring target vehicle confirmation unit 14 of the vehicle 1A receives the self-identification information transmitted from the vehicle 1B if the information is received in step S31 (step S13).

  The monitored vehicle confirmation unit 14 of the vehicle 1A transmits self-identification information for identifying the own vehicle 1A from the storage unit 12 to the vehicle 1B (step S14), and the monitored vehicle confirmation unit 14 of the vehicle 1B The self-identification information transmitted from 1A is received (step S15).

  Thereby, the vehicle-mounted control apparatus of vehicle 1A and the vehicle-mounted control apparatus of vehicle 1B can be synchronized. In subsequent step S38, the monitoring means 15 checks whether or not there is a change in the distance between the own vehicle and the vehicle to be monitored. At this time, both the vehicle 1A and the vehicle 1B are powered at the same timing. And check changes in the distance between vehicles. After confirming the change in distance, the supply of power stops in a certain time.

  FIG. 6 is a flowchart showing an example of processing when canceling the monitoring mode of the vehicle-mounted control device according to the first embodiment of the present invention.

  First, the monitoring canceling means 18 confirms whether or not the owner of the vehicle 1 has unlocked the door and the operation receiving means 13 has received the cancellation of the monitoring mode (step S21).

  When the operation accepting unit 13 accepts the cancellation of the monitoring mode in step S21, the monitoring cancellation unit 18 notifies the vehicle that has been monitoring the own vehicle that the monitoring mode has been canceled via the communication interface 11 (step S21). S22).

  Next, the monitoring canceling means 18 determines whether or not the order of vehicles for canceling the monitoring mode follows a specific order (step S25). As a method for determining the release order of the vehicles that release the monitoring mode, the trigger for releasing the monitoring mode is 2 when the owner of the vehicle 1 is notified from the vehicle to be monitored when the door is unlocked. Therefore, the release order is determined based on the context of these triggers and from which vehicle.

  In the first embodiment of the present invention, it is assumed that the specific order for canceling the monitoring mode is set such that the vehicle 1B is first and the vehicle 1A is next. Under this condition, when the unlocking of the door of the own vehicle is performed in step S25 prior to the notification (release) from the vehicle to be monitored, in the vehicle 1B, the monitoring canceling means 18 follows the specific order. In the vehicle 1A, the monitoring canceling means 18 determines that it does not follow a specific order.

  If the monitoring canceling means 18 determines that the specific order is being followed in step S25, the monitoring canceling means 18 causes the monitoring means 15 to cancel the monitoring of the vehicle (step S26). Moreover, when it determines with the monitoring cancellation | release means 18 not having followed the specific order in step S25, it makes the warning means 16 alarm (step S27).

  If the operation accepting unit 13 has not accepted the cancellation of the monitoring mode in step S21, the monitoring releasing unit 18 confirms whether or not the notification accepting unit 17 has received a notification that the monitoring mode has been released from the vehicle to be monitored. (Step S23).

  If it is determined in step S23 that the notification indicating that the monitoring mode has been canceled has not been received, the process returns to step S21. When the notification indicating that the monitoring mode is cancelled is received, the monitoring canceling means 18 determines whether or not the order of vehicles for canceling the monitoring mode follows a specific order (step S24).

  In step S24, when the notification from the vehicle to be monitored is made prior to the unlocking of the door, it is determined that the monitoring release means 18 of the vehicle 1A is in a specific order, and the vehicle 1B is monitored. If it is the cancellation | release means 18, it will determine with not following a specific order.

  If the monitoring canceling means 18 determines in step S24 that the specific order is being followed, the process returns to step S21 again. If the monitoring canceling means 18 determines in step S24 that the specific order is not being followed, the monitoring canceling means 18 An alarm is generated (step S27).

  The process related to the monitoring mode of the in-vehicle control device according to the first embodiment of the present invention has been described above. Here, a registration method for automatically registering the monitoring target identification information in the storage unit 12 will be described with reference to FIG. FIG. 7 is a sequence diagram showing an example of processing related to the registration mode of the in-vehicle control device according to the embodiment of the present invention.

  First, the vehicle-mounted control device 10 of the vehicle 1A parked in the parking lot is in a registration mode in which the monitoring target identification information is automatically registered in the storage means 12, and the vehicle 1B is as shown in FIG. When the vehicles 1 are within the monitorable range, it is assumed that the vehicle-mounted control device 10 of the vehicle 1A is set to the registration mode by the owner operating the operation receiving unit 13 of the vehicle 1B. At this time, the monitoring target vehicle confirmation unit 14 of the vehicle 1B transmits the self-identification information of the vehicle 1B to the in-vehicle control device 10 of the vehicle 1A (step S31).

  The monitoring target vehicle confirmation unit 14 of the vehicle 1A receives the self identification information of the vehicle 1B transmitted from the vehicle 1B (step S32), and registers the self identification information of the vehicle 1B in the storage unit 12 as the monitoring target identification information ( Step S33), the self-identification information of the vehicle 1A is transmitted to the vehicle-mounted control device 10 of the vehicle 1B (step S34).

  The monitoring target vehicle confirmation unit 14 of the vehicle 1B receives the self identification information of the vehicle 1A transmitted from the vehicle 1A (step S35), and registers the self identification information of the vehicle 1A in the storage unit 12 as the monitoring target identification information ( Step S36).

  The registration method for automatically registering the monitoring target identification information in the storage unit 12 has been described above. However, the owner may manually register the monitoring target identification information in the storage unit 12. Further, the owners of the vehicles 1A and 1B may be the same, or the owners of the vehicles 1A and 1B may be different as long as mutual registration is permitted by reliable parties. Note that once the monitoring target identification information is registered in the storage unit 12, it is stored in the storage unit 12 until it is deleted by the user.

  Moreover, the vehicle-mounted control apparatus 10 may make it impossible to register monitoring object identification information unless the mutual vehicles to be monitored are trusted. For example, the in-vehicle control device 10 has a list of identification information related to a trusted vehicle, and if the identification information for registering the vehicle to be monitored is not included in this list, the registration of the identification information is rejected. You may make it do.

  As described above, the vehicle anti-theft system according to the first embodiment of the present invention can not release the monitoring mode of the vehicle to be monitored only in a specific order determined by the owner. If a thief who doesn't know the order of the vehicle impersonates the owner and tries to unlock other vehicles illegally, an alarm can be issued, making it difficult to steal the vehicle to be monitored and preventing vehicle theft Can improve security for.

(Second embodiment of the present invention)
In the vehicle antitheft system according to the first embodiment of the present invention, the case where there are two vehicles to be monitored is exemplified, but there may be three or more vehicles to be monitored. In the vehicle antitheft system according to the second embodiment of the present invention, a case where there are three vehicles to be monitored will be described.

  FIG. 8 is a schematic diagram of a vehicle antitheft system according to the second embodiment of the present invention. Hereinafter, regarding the configuration of the vehicle antitheft system according to the second embodiment of the present invention, the same components as those constituting the vehicle antitheft system according to the first embodiment of the present invention are denoted by the same reference numerals. A description thereof will be omitted. In addition, when distinguishing each of the three vehicles 1, it describes as vehicle 1A, vehicle 1B, and vehicle 1C. Moreover, the vehicle-mounted control apparatus 10 is mounted in the vehicle 1A, the vehicle 1B, and the vehicle 1C.

  As shown in FIG. 8, the vehicle 1A is within the monitorable range of the vehicle 1B, the vehicles 1B and 1C are within the monitorable range of the vehicle 1A, and the vehicle 1A is within the monitorable range of the vehicle 1C. There is.

  FIG. 9 shows vehicles that are monitored by the vehicles 1A, 1B, and 1C. The storage unit 12 of the vehicle 1A stores monitoring target identification information for identifying the vehicle 1B and monitoring target identification information for identifying the vehicle 1C. Moreover, the monitoring target identification information for identifying the vehicle 1A is stored in the storage unit 12 of the vehicle 1B, and the monitoring target identification information for identifying the vehicle 1A is stored in the storage unit 12 of the vehicle 1C.

  In addition, the vehicle-mounted control devices 10 of the vehicle 1A, the vehicle 1B, and the vehicle 1C are each in the monitoring mode, the vehicle 1A monitors the vehicle 1B and the vehicle 1C, the vehicle 1B monitors the vehicle 1A, and the vehicle 1C 1A is being monitored.

  Here, it is assumed that if both the vehicle 1B and the vehicle 1C do not cancel their own monitoring mode, the order in which the vehicle 1A cannot cancel itself is determined. Accordingly, the monitoring canceling means 18 of the vehicle 1A first receives a notification that the monitoring mode has been canceled from both the vehicle 1B and the vehicle 1C via the notification receiving means 17, and receives the monitoring mode via the operation receiving means 13. When the release is received later, the monitoring mode is released normally, but when the release of the monitoring mode is received first, the alarm means 16 is made to give an alarm.

  As described above, the vehicle anti-theft system according to the second embodiment of the present invention will not receive the notification that the monitoring mode has been canceled from all the vehicles to be monitored in advance. Since it becomes impossible to cancel the vehicle monitoring mode, the conditions for canceling the monitoring mode become complicated, and the security for preventing vehicle theft can be further improved.

  As described above, according to the present invention, when vehicles are prevented from being stolen by mutually monitoring each other, it is possible to give an alarm when impersonating a vehicle owner and attempting to illegally cancel the vehicle monitoring. It has the effect of improving security for preventing vehicle theft, and is useful as an in-vehicle control device for preventing vehicle theft.
