Description

Distribution system

The present invention relates to a distribution system.

Conventionally, in a VICS (Vehicle Information and Communication System) service using DSRC (Dedicated Short Range Communication), the vehicle-mounted device transmits (uplinks) various information about the vehicle to the server. The information uplinked to the server includes vehicle-mounted device information for identifying the vehicle-mounted device and vehicle information related to the vehicle. In addition, vehicle travel history information, behavior history information, and the like stored in the memory of the vehicle-mounted device are uplinked to the server.

The vehicle information to be uplinked includes the land transportation branch office code, the usage code, and the vehicle type classification number excluding the 4-digit serial number included in the vehicle license plate. In services provided by government agencies (hereinafter referred to as government services), license plate information including serial numbers corresponds to personal information defined by the Act on the Protection of Personal Information of Administrative Organizations. Therefore, in the present situation, this serial number is not included in the vehicle information that is uplinked in the public service.

On the other hand, a service provided by the private sector (hereinafter referred to as a private service) does not correspond to personal information when only license plate information is handled. However, if it is used in combination with other information (such as a credit card holder), it may correspond to personal information.
Also, even if it does not correspond to personal information, there is a possibility of infringement of privacy, so for the purpose of privacy protection, it is necessary to determine whether it is a roadside machine that can be uplinked and to uplink the serial number is there.

In private services such as time-rented parking lots, the license plate of the vehicle is photographed with a camera, and license plate information is obtained through image recognition. The private service provider manages entry / exit of vehicles based on the license plate information. However, if the image taken by the camera is unclear, the license plate information cannot be acquired by image recognition. For this reason, there is a possibility that the provider of the private service cannot obtain the license plate information of the vehicle and provide the service.

Also, by uplinking license plate information including a serial number from the vehicle-mounted device, the private service provider can identify a vehicle that has been parked for a long time. In addition, when it is necessary to call the driver due to forgetting to turn off the hazard lamp of the vehicle, the license plate information can be notified to the driver by in-store broadcasting or the like. In order to perform these services, the license plate information including the serial number must be notified from the vehicle to the service provider in addition to the information currently uplinked.

In recent years, OBD (On Board Diagnosis) 2 interface has been installed in vehicles as standard. With this interface, when a component abnormality is found by various sensors mounted on the vehicle, error information is stored in the engine computer. The stored error information is notified to the server via wireless communication or the like. That is, when the vehicle passes under the DSRC antenna, the vehicle state can be transmitted to the server, and the vehicle can be inspected (simple health check). Even during this inspection, the vehicle cannot be identified unless the license plate information including the serial number is transmitted to the server.
