Description

This disclosure relates to a data communication system, a data center device , a data processing method, and a data processing program. According to a data communication system in one aspect of the present disclosure, a center device and a vehicle device mounted on a vehicle are capable of data communication. The center device includes a distribution target identification unit that identifies targets for distribution of trigger conditions for detecting a predetermined scene on the vehicle side based on vehicle equipment; a trigger condition creation unit that creates the trigger conditions corresponding to the distribution targets; a collection data list creation unit that creates a collection data list corresponding to the trigger conditions; a distribution unit that distributes the trigger conditions and the collection data list to the vehicle device of the distribution target; and a collection data acquisition unit that acquires the collection data indicated by the collection data list from the vehicle device. The vehicle device includes a detection data acquisition unit that acquires detection data necessary for trigger condition determination; a trigger condition determination unit that performs trigger condition determination based on the detection data and the trigger conditions; a collection data creation unit that creates collection data based on the determination result of the trigger condition determination; and a collection data transmission unit that transmits the collection data to the center device. The distribution target identification unit identifies the distribution targets in addition to the vehicle equipment based on driver characteristics. According to one aspect of the present disclosure, a center device is mounted in a vehicle and is capable of data communication with a vehicle device that performs trigger condition determination based on detection data necessary for trigger condition determination, creates collected data based on the determination result of the trigger condition determination, and transmits it to the center device. The center device comprises: a distribution target identification unit that identifies the distribution target of trigger conditions for detecting a predetermined scene on the vehicle side based on vehicle equipment; a trigger condition creation unit that creates the trigger conditions corresponding to the distribution target; a collected data list creation unit that creates a list of collected data corresponding to the trigger conditions; a distribution unit that distributes the trigger conditions and the collected data list to the vehicle device of the distribution target; and a collected data acquisition unit that acquires the collected data from the vehicle device. The distribution target identification unit identifies the distribution target in addition to the vehicle equipment based on driver characteristics. According to a data processing method for a data communication system in one aspect of the present disclosure, the center device executes: a distribution target identification procedure for identifying distribution targets for trigger conditions to detect a predetermined scene on the vehicle side based on vehicle equipment; a trigger condition creation procedure for creating trigger conditions corresponding to the distribution targets; a collection data list creation procedure for creating a collection data list corresponding to the trigger conditions; a distribution procedure for distributing the trigger conditions and the collection data list to the vehicle equipment of the distribution targets; and a collection data acquisition procedure for acquiring collection data indicated by the collection data list from the vehicle equipment. The vehicle equipment executes: a detection data acquisition procedure for acquiring detection data necessary for trigger condition determination; a trigger condition determination procedure for performing trigger condition determination based on the detection data and the trigger conditions; a collection data creation procedure for creating collection data based on the determination result of the trigger condition determination; and a collection data transmission procedure for transmitting the collection data to the center device. The distribution target identification procedure identifies the distribution targets in addition to the vehicle equipment, based on driver characteristics. According to a data processing method for a center device in one aspect of the present disclosure, a center device capable of data communication with a vehicle device mounted in a vehicle, which performs trigger condition determination based on detection data necessary for trigger condition determination, and creates and transmits collected data to the center device based on the determination result of the trigger condition determination, performs a distribution target identification procedure for identifying the distribution target
