Communicate with the mobile terminal 4 or the communication device 5 via.

  In the monitoring system having the above-described configuration, the body ECU (first determination unit) 1 determines the vehicle C based on various information acquired from each connected device while the vehicle C is parked (operation stopped). Determine whether the condition is normal. For example, when the intrusion detection sensor 15 detects the intrusion of a person into the vehicle C, the body ECU 1 determines that the state of the vehicle C is not normal. Further, the body ECU 1 determines that the state of the vehicle C is not normal when any door, window, or bonnet is pry open when each door of the vehicle C is locked by the door lock mechanism 11. Further, the body ECU 1 displays information indicating the state of the vehicle C when the vehicle C is parked, specifically when each door of the vehicle C is locked by the door lock mechanism 11. ) Periodic transmission that is periodically transmitted to the notification device 3 via 10 is performed.

  The notification device 3 receives information periodically transmitted from the body ECU 1 (periodically transmitted) by the wireless communication unit (reception unit) 33, and thereby can grasp the state of the vehicle C. The control unit (second determination unit) 30 of the notification device 3 determines whether the received information is information indicating that the state of the vehicle is normal. When the received information is not information indicating normality, i.e., information indicating abnormality, the control unit 30 is set in advance for the body ECU 1 that has transmitted this information. The device is notified (notified) by the network connection unit (notification unit) 34. The storage unit 32 of the notification device 3 stores a notification destination database (hereinafter referred to as a notification destination DB) 32a, and the control unit 30 identifies the notification destination device based on the notification destination DB 32a.

  FIG. 3 is a schematic diagram showing the stored contents of the report destination DB 32a. In the report destination 32a shown in FIG. 3, identification information, report destination information, a communication execution flag, a reception date and time, and the like are stored in association with each vehicle C to be monitored by the monitoring system. The identification information is information for identifying each vehicle C or the body ECU 1 mounted on each vehicle C. For example, address information used when each body ECU 1 performs wireless communication with the notification device 3 is used. it can. The report destination information is information on a report destination to be notified when an abnormality occurs in each vehicle C. The report destination information is, for example, the telephone number, e-mail address, or address information used for data communication of the portable terminal 4 carried by the user (owner) of each vehicle C. The report destination information is the telephone number, mail address, or address information of the communication device 5 managed by the security company or police station with which the user of each vehicle C is contracted. The communication execution flag is information indicating whether or not the monitoring process for each vehicle C is being executed, and “1” is stored if it is being executed, and “0” is stored if it is not being executed. The reception date and time is the date and time when the reporting device 3 last received information (information indicating the state of the vehicle C) periodically transmitted from each vehicle C in order to monitor the state of each vehicle C.

  A user who wants to monitor his own vehicle C in the monitoring system registers in advance. Therefore, the identification information and report destination information of each vehicle C are stored in the report destination DB 32a by the control unit 30 when each user registers. When the start of the monitoring process is instructed from each vehicle C (body ECU 1), the communication execution flag stores “1” in the notification destination DB 32a by the control unit 30 and instructs the end of the monitoring process from each vehicle C. If it is, the control unit 30 stores “0” in the report destination DB 32a. The reception date and time stored in the report destination DB 32a is updated by the control unit 30 every time the wireless communication unit 33 receives information periodically transmitted from each body ECU 1.

Below, the process which body ECU1 mounted in each vehicle C performs in the monitoring system of this Embodiment 1 is demonstrated. FIG. 4 is a flowchart showing a procedure of processing performed by the body ECU 1 while the vehicle C is parked.
After the vehicle C stops according to the user's operation, the body ECU 1 locks each door of the vehicle C with the door lock mechanism 11 when the user performs an instruction to lock the door (S1). Become. Note that the body ECU 1 automatically opens each door of the vehicle C after a predetermined time has elapsed since the passenger got off after the vehicle C stopped (after any door of the vehicle C was opened or closed). It may be configured to lock.

Next, the body ECU 1 notifies the notification device 3 from the wireless communication unit 10 of the start of communication (start of monitoring by the monitoring system) (S2). And body ECU1 starts the regular transmission which transmits the information which shows the state of the vehicle C from the radio | wireless communication part 10 to the notification apparatus 3 regularly (S3). The body ECU 1 periodically transmits information indicating that the state of the vehicle C is normal when there is no abnormality in the vehicle C.
The body ECU 1 determines whether or not the engine of the vehicle C has been started (S4). If the body ECU 1 determines that the engine has not been started (S4: NO), the body ECU 1 Based on the information, it is determined whether or not an abnormality has occurred in the vehicle C (S5). The body ECU 1 may periodically perform a determination process as to whether or not an abnormality has occurred in the vehicle C, or perform a determination process each time information is acquired from each device mounted on the vehicle C. May be.

  When it is determined that no abnormality has occurred in the vehicle C (S5: NO), the body ECU 1 returns the process to step S4 and continues to periodically transmit information indicating that the state of the vehicle C is normal. When it is determined that an abnormality has occurred in the vehicle C (S5: YES), the body ECU 1 transmits information (abnormality occurrence information) indicating that the state of the vehicle C is not normal from the wireless communication unit 10 to the notification device 3. (S6). The body ECU 1 may transmit the abnormality occurrence information to the notification device 3 by regular transmission, or may transmit the abnormality occurrence information when the occurrence of the abnormality is detected.

When it is determined that the engine has been started (S4: YES), the body ECU 1 determines whether or not the engine of the vehicle C has been started by a normal operation by the user (S7). For example, when the keyless entry system is mounted on the vehicle C, the normal operation means that the door lock of the vehicle C is released by the operation of the mobile key by the user, and then the mobile key or the key provided on the mobile key is used. This is an operation to turn on the ignition switch.
When it is determined that the engine of the vehicle C is not started by a normal operation by the user (S7: NO), for example, when the release of the door lock of the vehicle C is not due to the operation of the portable key, the body ECU 1 Abnormality occurrence information is transmitted from the wireless communication unit 10 to the reporting device 3 (S6).

When it is determined that the engine of the vehicle C has been started by a normal operation by the user (S7: YES), the body ECU 1 (stop notification unit) reports the end of communication (end of monitoring by the monitoring system) from the wireless communication unit 10 The device 3 is notified (S8). Then, the body ECU 1 ends the regular transmission started in step S3 (S9).
After transmitting the abnormality occurrence information to the reporting device 3 once, the body ECU 1 may end or continue the above-described processing (processing for detecting the occurrence of abnormality and processing for notifying the reporting device 3 of the occurrence of abnormality). May be. By the processing described above, when any abnormality occurs in the vehicle C, the notification device 3 can be notified. In addition, after the vehicle C starts traveling by a normal operation by the user, it is excluded from the monitoring target by the monitoring system, so that erroneous detection can be prevented.

Next, processing performed by the reporting device 3 in the monitoring system of the first embodiment will be described. FIG. 5 is a flowchart showing a procedure of processing performed by the reporting device 3.
The control unit 30 of the reporting device 3 determines whether or not the start of communication has been notified from any of the body ECUs 1 mounted on each vehicle C (S11), and determines that it has not been notified ( (S11: NO), the process proceeds to step S13. If it is determined that any body ECU 1 has notified the start of communication (S11: YES), the control unit 30 corresponds to the notified body ECU 1 (vehicle C in which the body ECU 1 is mounted) in the notification destination DB 32a. The communication execution flag to be updated is updated to “1” (S12). Thereby, the monitoring process for the vehicle C is started.

The control unit 30 determines whether information (information indicating the state of the vehicle C) periodically transmitted by any of the body ECUs 1 has been received by the wireless communication unit 33 (S13). If it is determined that it has been received (S13: YES), the control unit 30 determines whether or not the received information is abnormality occurrence information (S14). When it is determined that the received information is not abnormality occurrence information (S14: NO), the control unit 30 returns the process to step S13.
When it is determined that the received information is abnormality occurrence information (S14: YES), the control unit 30 reads out notification destination information to be notified of the occurrence of abnormality from the notification destination DB 32a (S15). Specifically, the control unit 30 reads out the report destination information stored in the report destination DB 32a in association with the identification information of the body ECU 1 that has transmitted the abnormality occurrence information.

  The control unit 30 reports to the report destination terminal indicated by the report destination information that the abnormality has occurred in the vehicle C by the read report destination information (S16). Specifically, when the report destination information is an e-mail address, the control unit 30 creates a message indicating that an abnormality has occurred in the vehicle C, and transmits the e-mail using the e-mail transmission function. Further, when the report destination information is a telephone number, the control unit 30 makes a call, and when communication with the report destination is started, the control unit 30 outputs a voice message indicating that an abnormality has occurred in the vehicle C. Further, when the report destination information is address information used for data communication, the control unit 30 creates a message indicating that an abnormality has occurred in the vehicle C and transmits the data. Note that the mail transmission function, the voice output function, and the data transmission function are provided in advance in the notification device 3. If the notification device 3 has only a part of the mail transmission function, the voice output function, and the data transmission function, the notification device 3 What is necessary is just to perform the notification process using the function which has. When the abnormality occurrence information transmitted from the body ECU 1 includes information regarding the abnormality that has occurred, the control unit 30 can also report the type of abnormality that has occurred.

  After reporting to a predetermined reporting destination, the control unit 30 sends a notification from the radio communication unit 33 to the body ECU 1 whose communication execution flag of the reporting destination DB 32a is 1, that is, the body ECU 1 of the vehicle C to be monitored. The start of notification processing for notifying that there is a vehicle C in which an abnormality has occurred is instructed (S17). Specifically, the control unit (command transmission unit) 30 transmits a notification processing execution command. The body ECU (notification unit) 1 instructed to start the notification process outputs, for example, a warning sound (alarm sound) from the horn 16, blinks the hazard lamp 17, lights the indoor lamp 18 or the headlight 19, and Informs that there is an abnormality in the parked vehicle C. As a result, for example, each vehicle C parked in a parking lot in which the car is tampered with can be warned and notified. Note that a sound output device such as a buzzer or a speaker for generating a warning sound, a dedicated lamp or light for warning may be provided.

  On the other hand, when it is determined that information (information indicating the state of the vehicle C) has not been received from the body ECU 1 (S13: NO), the control unit 30 determines a predetermined time (from the reception date and time stored in the report destination DB 32a). For example, it is determined whether there is a body ECU 1 that has stopped receiving information for several tens of seconds or several minutes (S18). Specifically, the control unit 30 compares each reception date and time stored in the report destination DB 32a with the time indicated by its own clock, and determines a predetermined time (several times or ten times the transmission timing of information by regular transmission). It is determined whether or not there is a body ECU 1 that has passed more than a certain amount of time. If it is determined that no body ECU 1 has received information for a predetermined time or longer (S18: NO), the control unit 30 returns the process to step S11.

If it is determined that there is a body ECU 1 that has stopped receiving information for a predetermined time or longer (S18: YES), the control unit 30 proceeds to step S15. Then, the control unit 30 reads out the report destination information stored in the report destination DB 32a in association with the identification information of the body ECU 1 that has stopped receiving information for a predetermined time or more (S15), and reports (S16).
Thereby, for example, when the battery of the vehicle C is pulled out or when the power supply from the battery is cut off, the body ECU 1 cannot operate and cannot notify the notification device 3 of the occurrence of the abnormality. Even in this case, the reporting device 3 can detect that some abnormality has occurred in the vehicle C and can report at an early stage.

  When there is a body ECU 1 that has stopped receiving information for a predetermined time or longer, the control unit 30 accesses the body ECU 1, and when there is no response to the access, the body ECU 1 cannot communicate. It is possible to make a determination and notify the corresponding report destination. Specifically, the control unit 30 transmits predetermined information from the wireless communication unit (transmitting unit) 33 to the body ECU 1 that has stopped receiving information for a predetermined time or longer, and wirelessly transmits response information for the transmitted information. Received by the communication unit (response receiving unit) 33. When the response information cannot be received, the control unit 30 determines that the body ECU 1 is in a state where it cannot communicate, that is, is not in a normal state.

  Next, the control unit 30 determines whether or not the end of communication is notified from any of the body ECUs 1 that regularly transmit information (S19), and determines that it is not notified (S19: NO) ), The process returns to step S11. When it is determined that the end of communication is notified from any body ECU 1 (S19: YES), the control unit 30 updates the communication execution flag corresponding to the notified body ECU 1 to “0” in the notification destination DB 32a ( S20). Thereby, the control part (determination stop part) 30 complete | finishes the process which judges whether the state of this vehicle C is normal based on the information from body ECU1 mounted in this vehicle C, The monitoring process for the vehicle C ends.

  Since the monitoring system of the first embodiment monitors the state of the parked vehicle C, there is a possibility that the battery will run out (insufficient power from the battery) in each vehicle C. When the battery runs out, sufficient power is not supplied to the body ECU 1, so the body ECU 1 is stopped. Accordingly, the body ECU 1 cannot periodically transmit information indicating the state of the vehicle C. In this case, the reporting device 3 erroneously determines that an abnormality has occurred in the vehicle C. Therefore, the body ECU 1 is configured to detect the output voltage of the battery by the battery voltage monitor 16 and end the monitoring process of the vehicle C by the monitoring system according to the detection result.

The battery voltage monitoring process performed by the body ECU 1 will be described below. FIG. 6 is a flowchart showing a procedure of battery voltage monitoring processing by the body ECU 1.
The body ECU 1 detects the output voltage (battery voltage) of the battery by the battery voltage monitor (detection unit) 16 while performing the process shown in FIG. 4, and determines whether or not the detected battery voltage is equal to or lower than a predetermined value. (S31). When it is determined that the battery voltage is not lower than the predetermined value (S31: NO), the control unit 30 stands by while performing other processes.

When it is determined that the battery voltage is equal to or lower than the predetermined value (S31: YES), the body ECU 1 (notification unit) notifies the notification device 3 from the wireless communication unit 10 of the end of communication (end of monitoring by the monitoring system) (S32). ). Note that the notification process here is the same as the process of step S8 in FIG. 4, and the notified device 3 determines that the communication end has been notified from the body ECU 1 in step S19 of FIG. To do. Then, the control unit (stop unit) 30 of the notification device 3 updates the communication execution flag corresponding to the notified body ECU 1 to “0” in the notification destination DB 32a (S20), and ends the monitoring process for the vehicle C. (Stop.
Even if the battery has run out (insufficient power from the battery) due to the above-described processing, the monitoring processing for the vehicle C is terminated in advance, so that erroneous determination by the reporting device 3 can be prevented.

  In the monitoring system of the first embodiment described above, the state of the vehicle C parked in a predetermined parking lot is detected, and when any abnormality occurs, the pre-registered report destination is notified, so the vehicle is roughened. Alternatively, when the vehicle C is stolen, an early notification can be made.
