More Information
Summary:A communication apparatus on a subject vehicle detects surrounding vehicles based on a detection result of a radar or the like for generating a subject device vehicle data list. Then, similar lists are acquired from other apparatuses for deleting co-existing vehicles from the subject device vehicle data list. Co-existing vehicles are also deleted from the subject device vehicle data list by receiving the similar lists from roadside devices. Then, the subject device vehicle data list is transmitted to other vehicles. In this manner, the total amount of communication data exchanged between apparatuses is reduced due to a reduction of duplicated vehicle information.
