ON−VEHICLE DEVICE NETWORK SYSTEM AND POWER SUPPLY CONTROL APPARATUS

摘要

A network system of on−vehicle electric devices where a central control unit mounted on a vehicle is connected to a plurality of on−vehicle electric devices and power supply control apparatus. The network system includes an antenna for transmitting/receiving a signal by radio, an on−vehicle transmission/reception apparatus connected by a line to the central control unit, and an antenna for transmitting/receiving a signal to/from the transmission/reception apparatus. The on−vehicle electric devices are controlled according to the signal received. Moreover, the system includes a plurality of electric device control apparatuses or power control apparatuses arranged for each of the on−vehicle electric devices, for processing signals generated by the on−vehicle electric devices and transmitting the signals to the transmission/reception apparatus. Instead of the antenna of the transmission/reception apparatus, it is also possible to use a current leak device connected in series by the central control unit and a high−frequency wave cable, arranged in the vicinity of each of the on−vehicle electric devices, and generating a radio wave corresponding to the aforementioned signal in the vicinity of the on−vehicle electric devices.
