Abstract:
1. An onboard device comprising a controller, and when driving status information of a pertinent vehicle that is acquired from a pertinent vehicle detector device of a plurality of vehicle detector devices is prevented from continuing to be acquired from the pertinent vehicle detector device of the plurality of vehicle detector devices after the driving status information of another vehicle acquired from other vehicle detector devices of the plurality of vehicle detector devices mounted on a host vehicle and configured to detect a different vehicle than the host vehicle has been determined to be the driving status information of the same pertinent vehicle acquired from the pertinent vehicle detector device, the controller is configured to: generate the driving status information of the pertinent vehicle by using current driving status information acquired from the other vehicle detector devices and a difference between the driving status information acquired by the pertinent vehicle detector device and the driving status information acquired by the other vehicle detector devices when the driving status information of the other vehicle acquired from the other vehicle detector devices is determined to be the driving status information of the same pertinent vehicle; and output the generated driving status information of the other vehicle, wherein a plurality of the vehicle detector devices configured to detect a different vehicle than the host vehicle include a first vehicle detector device that detects driving status information of the other vehicle according to position and vehicle speed vector information transmitted from the other vehicle by wireless communication and a second vehicle detector device that detects driving status information of the other vehicle by using a sensor, and when the driving status information of a certain other vehicle using the sensor becomes unavailable after determining, regarding a certain other vehicle, that the driving status information of a certain other vehicle using wireless communication and the driving status information of a certain other vehicle using the sensor indicate the same vehicle, the controller is further configured to output, as positional information on the pertinent vehicle, such positional information as is generated by adding a differential value of positional information of the detected information on the pertinent vehicle acquired from wireless communication to the positional information on the pertinent vehicle obtained when the sameness of the vehicle is determined.
