COMMUNICATION CONTROL APPARATUS, POWER LINE COMMUNICATION INTERFACE CIRCUIT, AND ON-VEHICLE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a communication control apparatus, a power line communication interface circuit and an on-vehicle apparatus which can relieve the work of attaching an additional device such as an ETC on-vehicle device by making communication between the additional device and the communication control apparatus such as an on-vehicle gateway device via a power line for feeding power from a power source such as a battery provided in a vehicle.

SOLUTION: A GW device 1 for controlling the communication of the on-vehicle device such as audio 101 or monitor 102 is connected to a power feeding cable which interconnects a battery 2 and a cigar socket 3a, and additional devices such as the ETC on-vehicle device 5 and an MD player 7 equipped with an adapter unit 6 in the middle are interconnected through the cable to cigar terminals 4a, 4b attachable/detachable to/from the cigar socket 3a.
