Further, the vehicle monitoring system 10 transmits information prompting the change of the parking schedule information output from the server 11 to the mobile phone 23 as e-mail information.

[Basic operation of vehicle monitoring system]
Hereinafter, the basic operation of the vehicle monitoring system 10 of the present embodiment will be described with reference to the flowchart of FIG.

  The vehicle monitoring system 10 of this embodiment is applied to a parking lot management system that monitors a vehicle 20 that uses a parking lot 200, as shown in FIG.

  First, the server 11 recognizes the state of movement or stop of the vehicle 20 in the parking area in the parking lot 200 based on image information (video) captured by the camera 15 via the image processing device 14. The server 11 receives the parking schedule information input from the user of the vehicle 20 that has entered the parking lot 200 (step S1). The parking schedule information is information indicating the scheduled parking time from the time of stopping at the parking lot 200. The vehicle monitoring system 10 receives parking schedule information as e-mail information from the user's mobile phone 23 and transfers it to the server 11. Further, if the vehicle-mounted device 21 can transmit information input by the user's input operation through DSRC wireless communication, the roadside device 12 receives the parking schedule information transmitted from the vehicle-mounted device 21 through DSRC wireless communication and receives the server 11 You may forward to.

  On the other hand, the roadside device 12 receives vehicle information including user ID information from the vehicle-mounted device 21 mounted on the vehicle 20 by DSRC wireless communication, and transfers the vehicle information to the server 11 (step S2). The server 11 registers (saves) the parking schedule information associated with the user ID information transmitted from the vehicle-mounted device 21 via the roadside device 12 in the storage device (step S3).

  Next, the server 11 detects the start of the parked vehicle 20 according to the vehicle information transferred from the roadside device 12 (step S4). When the vehicle 20 starts the engine, the roadside device 12 receives vehicle information transmitted from the vehicle-mounted device 21 and transfers the vehicle information to the server 11. The server 11 detects the start of the vehicle 20 by including information indicating engine start in the acquired vehicle information.

  The server 11 refers to the parking schedule information registered by the user ID information of the activated vehicle 20, and determines whether or not the schedule of the parking schedule information is met (step S5). In other words, the server 11 determines that the time is normal when the time when the vehicle 20 is activated is within the range of the scheduled parking time specified by the parking schedule information (NO in step S5). In this case, the server 11 releases various security in the parking lot 200 (step S7). Accordingly, the vehicle 20 moves from the parking area to the gate of the parking lot 200 and executes a normal predetermined process (such as a parking fee payment process).

  On the other hand, if the time when the vehicle 20 is activated is outside the range of the scheduled parking time specified by the parking schedule information, the server 11 determines that an abnormal state has occurred (YES in step S5). In this case, the server 11 executes a predetermined security process at the parking lot 200 (step S6).

  Specifically, the server 11 performs an alarm process on the vehicle-mounted device 21 of the vehicle 20 via the roadside device 12 and lights an alarm lamp or the like in the parking lot 200. Thereby, it is possible to notify that the vehicle 20 has an abnormality such as theft. In addition, when the user of the vehicle 20 has registered the telephone number or mail address of the mobile phone in advance, the server accesses the telephone number or mail address, and an abnormality such as theft of the vehicle 20 occurs. It is also possible to report what is being done. Furthermore, the server 11 can also control the gate of the parking lot 200 to prevent the vehicle 20 that has been determined to be abnormal from passing through the gate.

  In the present embodiment, as described above, the user of the vehicle 20 can change the initially registered parking schedule information at any time. Accordingly, when the user of the vehicle 20 moves the vehicle 20 outside the registered scheduled parking time range, if the parking schedule information is changed in advance, the server 11 determines that the movement is normal.

  As described above, in the vehicle monitoring system according to the present embodiment, the activation of the vehicle 20 can be detected by acquiring vehicle information using DSRC wireless communication with the vehicle-mounted device 21. Moreover, it can be determined by the registration of the parking schedule information from a user whether the starting or stopping state of the vehicle 20 is abnormal based on the registered schedule. Therefore, in the parking lot 200, the state of the vehicle 20 can be monitored with high accuracy.

  Further, by determining the abnormal state of the vehicle 20 based on the parking schedule information, it is possible to prevent theft by an alarm or report by executing a predetermined security process. In addition, the server 11 accesses the telephone number and mail address which were registered with respect to the user, and has exceeded the scheduled parking time when it has parked exceeding the scheduled parking time specified by the parking schedule information. It is also possible to report this.

  In addition, the server 11 can determine that the vehicle is illegally parked when the DSRC wireless communication with the vehicle-mounted device is invalid from the vehicle that has entered the parking lot 200 or the parking schedule information is not registered. In this case as well, it is possible to respond quickly to vehicles that have been illegally parked by security processing for alarms and reports.

  In short, the vehicle monitoring system of the present embodiment can realize high-accuracy vehicle monitoring and various vehicle monitoring services such as theft prevention, parking time management, and countermeasures against illegal parking.

[First application example]
FIG. 4 is a flowchart for explaining an application example of the vehicle monitoring system 10 of the present embodiment. The configuration of the vehicle monitoring system 10 is the same as that shown in FIG.

  First, similarly to the above-described basic operation, the server 11 accepts parking schedule information input from the user of the vehicle 20 that has entered the parking lot 200 (step S10). The roadside device 12 receives vehicle information including user ID information from the vehicle-mounted device 21 mounted on the vehicle 20 by DSRC wireless communication, and transfers the vehicle information to the server 11 (step S11). The server 11 registers (saves) the parking schedule information associated with the user ID information transmitted from the vehicle-mounted device 21 via the roadside device 12 in the storage device (step S12).

  Here, when the server 11 detects that the user of the vehicle 20 has approached the vehicle 20, the server 11 refers to the registered parking schedule information and determines whether or not a schedule change has occurred (step S13, S14). The server 11 uses the GPS (global positioning system) function of the mobile phone when the user of the vehicle 20 has registered the phone number or email address of the mobile phone in advance. By detecting the position, it is detected that the vehicle 20 has been approached.

  If it is within the range of the scheduled parking time designated by the parking schedule information, the server 11 determines that the schedule change is unnecessary (NO in step S14). In this case, the server 11 may cancel various security in the parking lot 200 (see step S18).

  On the other hand, if the server 11 is outside the range of the scheduled parking time specified by the parking schedule information, the user notifies the mobile phone of a message prompting the schedule change by e-mail (YES in step S14). The server 11 changes (re-registers) the registered parking schedule information in response to a change instruction from the user via the mobile phone.

  Similarly to the basic operation described above, the server 11 detects the start of the parked vehicle 20 in accordance with the vehicle information transferred from the roadside device 12 (step S15). The server 11 refers to the parking schedule information registered by the user ID information of the activated vehicle 20, and determines whether or not the schedule of the parking schedule information is met (step S16).

  The server 11 determines that the time when the vehicle 20 is activated is within the range of the scheduled parking time specified by the parking schedule information (NO in Step S16). In this case, the server 11 releases various security in the parking lot 200 (step S18). Accordingly, the vehicle 20 moves from the parking area to the gate of the parking lot 200 and executes a normal predetermined process (such as a parking fee payment process).

  On the other hand, if the time when the vehicle 20 is activated is outside the range of the scheduled parking time specified by the parking schedule information, the server 11 determines that an abnormal state has occurred (YES in step S16). In this case, the server 11 executes a predetermined security process at the parking lot 200 (step S17).

  As described above, in this application example, as described above, not only can the parking schedule information arbitrarily registered by the user of the vehicle 20 be changed, but also the system 10 can prompt the user to change the parking schedule information. it can. Therefore, highly accurate vehicle monitoring can be performed based on the parking schedule information. As described above, various vehicle monitoring services such as theft prevention, management of parking time, and countermeasures against unauthorized parking can be realized.

[Second application example]
FIG. 5 is a flowchart for explaining a second application example of the vehicle monitoring system 10 of the present embodiment. The configuration of the vehicle monitoring system 10 is the same as that shown in FIG.

  First, similarly to the above-described basic operation, the server 11 receives parking schedule information input from the user of the vehicle 20 that has entered the parking lot 200 (step S20). The roadside device 12 receives vehicle information including user ID information from the vehicle-mounted device 21 mounted on the vehicle 20 by DSRC wireless communication, and transfers the vehicle information to the server 11 (step S21). The server 11 registers (saves) the parking schedule information associated with the user ID information transmitted from the vehicle-mounted device 21 via the roadside device 12 in the storage device (step S22).

  Here, the server 11 determines that the user ID information transmitted from the vehicle-mounted device 21 via the roadside device 12 is the unauthorized ID information based on the determination criterion information (for example, a list of stolen vehicles) of the unauthorized ID information acquired in advance. It is determined whether or not (step S23). If the server 11 determines that the information is unauthorized ID information, the server 11 registers the user ID information in the list of unauthorized ID information (step S24).

  Furthermore, the server 11 reports that the vehicle-mounted device in which the unauthorized ID information is recorded is found in, for example, the management center that manages the user ID information of the vehicle-mounted device or the server of the vehicle monitoring system in another parking lot (step) S25). Next, the server 11 executes predetermined security processing at the parking lot 200 including alarm processing (step S26).

  If the information is not unauthorized ID information, the server 11 detects the start of the parked vehicle 20 according to the vehicle information transferred from the roadside device 12 (step S27), as in the basic operation described above. . The server 11 refers to the parking schedule information registered by the user ID information of the activated vehicle 20, and determines whether or not the schedule of the parking schedule information is met (step S28).

  The server 11 determines that the time when the vehicle 20 is activated is normal if it is within the range of the scheduled parking time specified by the parking schedule information (NO in step S28). In this case, the server 11 releases various security in the parking lot 200 (step S30). Accordingly, the vehicle 20 moves from the parking area to the gate of the parking lot 200 and executes a normal predetermined process (such as a parking fee payment process).

  On the other hand, if the time when the vehicle 20 is activated is outside the range of the scheduled parking time specified by the parking schedule information, the server 11 determines that an abnormal state has occurred (YES in step S28). In this case, the server 11 executes a predetermined security process at the parking lot 200 (step S29).

  As described above, in the case of this application example, as described above, it is possible to discover not only the vehicle monitoring in the parking lot 200 but also the vehicle-mounted device in which the unauthorized ID information is registered. A vehicle equipped with the vehicle-mounted device in which such illegal ID information is registered is highly likely to be a stolen vehicle. Therefore, not only the vehicle monitoring based on the parking schedule information but also the stolen vehicle can be monitored based on the vehicle information from the vehicle-mounted device.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
