VEHICLE COMMUNICATION APPARATUS

摘要

An information transfer ECU (110a) provided to a vehicle (100) acquires and accumulates vehicle information output from a plurality of vehicle ECUs (110) connected to a CAN communication line (120). Then, the information transfer ECU (110a) transfers the accumulated vehicle information to a portable information terminal (300) to/from which short-range radio communications have been established by a short-range communication control unit (150). The portable information terminal (300) transmits the transferred vehicle information to a vehicle information center (200) through an external communication line network (400) in order. When acquiring information for identifying the vehicle information whose transmission has been completed from the vehicle information center (200), the portable information terminal (300) supplies the information to the information transfer ECU (110a). The information transfer ECU (110a) erases the vehicle information whose transmission has been completed based on the acquired information.
