RELATED APPLICATIONS

The present application is a National Phase of International Application Number PCT/JP2017/013400 filed on Mar. 30, 2017.

TECHNICAL FIELD

The present invention relates to a vehicle management system, a vehicle-mounted device, a vehicle management method, and a program.

BACKGROUND ART

A technology in which a vehicle-mounted device mounted on a vehicle performs wireless communication with a roadside device installed on a roadside strip of a lane and a fee calculation device determines a vehicle passing a plurality of roadside devices installed with intervals therebetween to charge a toll for the vehicle according to passing these roadside devices has been disclosed. For example, Patent Document 1 discloses a technology for performing normal fee charging on vehicles entering an area at which fee charging is required in a non-stop manner using road-to-vehicle wireless communication.

SUMMARY OF INVENTION

Technical Problem

Incidentally, if it is possible to detect a travel route based on a position of a vehicle obtained by a mechanism such as a GPS even if a roadside device is not provided in a roadside strip with respect to a lane, the fee calculation device can calculate a fee for a travel section of a vehicle. However, it may not be possible to accurately ascertain the travel section of a vehicle due to falsification of information recorded in a vehicle-mounted device of the vehicle or powering off of the vehicle-mounted device.

Therefore, an object of the present invention is to provide a vehicle management system, a vehicle-mounted device, a vehicle management method, and a program which can solve the above problems.

Solution to Problem

According to a first aspect of the present invention, a vehicle management system includes a vehicle-mounted device and a vehicle management device, in which the vehicle-mounted device includes a vehicle identification unit that is configured to identify other vehicles from an image generated by photographing surroundings of a host vehicle using a photographing device, a reception information detector that is configured to detect identification information of the other vehicles on the basis of a signal received by inter-vehicle communication among vehicle-mounted devices of the other vehicles located within a communication range of the inter-vehicle communication, and a determination unit that is configured to determine whether identification information corresponding to the other vehicles identified from the image has been acquired.

In such a configuration, it is possible to ascertain a correspondence relationship between a vehicle identified by a photographing device and a vehicle identified based on information obtained by inter-vehicle communication.

In the vehicle management system described above, the vehicle-mounted device may include an image transmitter that is configured to transmit an image in which the identified other vehicles are reflected to the vehicle management device when the identification information corresponding to the other vehicles identified from the image cannot be acquired.

In such a configuration, it is possible to identify a vehicle having a vehicle-mounted device that does not perform inter-vehicle communication among vehicles photographed by a photographing device.

In addition, in the vehicle management system described above, the vehicle management device may further include a recording unit that is configured to record information on other vehicles whose identification information cannot be acquired as fraudulent vehicle candidates.

In such a configuration, it is possible to store an image indicating a vehicle having a vehicle-mounted device that does not perform inter-vehicle communication in a vehicle management device.

In addition, in the vehicle management system described above, the vehicle identification unit may identify other vehicles that are other vehicles traveling on an opposite lane from a plurality of images continuously acquired by a photographing device and are located within a communication range of the inter-vehicle communication and positional information of the other vehicles, the reception information detector may detect identification information of the other vehicles and the positional information detected by vehicle-mounted devices of the other vehicles based on a signal received by the inter-vehicle communication, and the determination unit may determine whether the identification information corresponding to other vehicles identified from the image has been acquired on the basis of a correspondence relationship between the positional information of identified other vehicles acquired from the plurality of images continuously acquired by the photographing device and the positional information detected by the reception information detector.

In such a configuration, it is possible to identify a vehicle having a vehicle-mounted device that does not perform inter-vehicle communication among vehicles which can be photographed by a photographing device.

According to a second aspect of the present invention, a vehicle-mounted device includes a vehicle identification unit configured to identify other vehicles from an image generated by photographing surroundings of a host vehicle using a photographing device, a reception information detector configured to detect identification information of the other vehicles on the basis of a signal received by inter-vehicle communication among vehicle-mounted devices of the other vehicles located within a communication range of the inter-vehicle communication, and a determination unit configured to determine whether identification information corresponding to the other vehicles identified from the image has been acquired.

In such a configuration, it is possible to ascertain a correspondence relationship between vehicles identified by a photographing device and vehicles identified based on information obtained by inter-vehicle communication.

According to a third aspect of the present invention, a vehicle management method in a vehicle management system having a vehicle-mounted device and a vehicle management device includes, by the vehicle-mounted device, identifying other vehicles from an image generated by photographing surroundings of a host vehicle using a photographing device, detecting identification information of the other vehicles on the basis of a signal received by inter-vehicle communication among vehicle-mounted devices of the other vehicles located within a communication range of the inter-vehicle communication, and determining whether identification information corresponding to the other vehicles identified from the image has been acquired.

In such a configuration, it is possible to ascertain a correspondence relationship between vehicles identified by a photographing device and vehicles identified based on information obtained by inter-vehicle communication.

According to a fourth aspect of the present invention, a program causes a computer of a vehicle-mounted device to function as a vehicle identifying unit that is configured to identify other vehicles from an image generated by photographing surroundings of a host vehicle using a photographing device, a reception information detecting unit that is configured to detect identification information of the other vehicles on the basis of a signal received by the inter-vehicle communication among vehicle-mounted devices of the other vehicles located within a communication range of the inter-vehicle communication, and a determination unit that is configured to determine whether identification information corresponding to the other vehicles identified from the image has been acquired.

In such a configuration, it is possible to ascertain a correspondence relationship between vehicles identified by a photographing device and vehicles identified based on information obtained by inter-vehicle communication.

Advantageous Effects of Invention

According to the present invention, it is possible to identify a vehicle having a vehicle-mounted device that does not perform inter-vehicle communication due to powering off or improper modification of the vehicle-mounted device.
