On-vehicle device network system and power supply control apparatus
First Claim
1. A network system of on-vehicle electric devices in which a central control unit mounted on a vehicle and a plurality of on-vehicle electric devices are connected, the network system comprising:
- one transmitter-receiver mounted on the vehicle and connected to the central control unit in a wired manner, the one transmitter-receiver including an antenna for transmitting/receiving therethrough a signal in a wireless manner; and
a plurality of electric device controllers provided in one-to-one correspondence to the plurality of on-vehicle electric devices, each of the electric device controllers including an antenna for transmitting/receiving therethrough a signal to/from the transmitter-receiver in a wireless manner so as to control corresponding one of the on-vehicle electric devices on the basis of the received signal or so as to process a signal generated by the corresponding one of the on-vehicle electric devices to transmit the processed signal to the transmitter-receiver.

Abstract
A network system of on-vehicle electric devices in which a central control unit mounted on a vehicle and a plurality of on-vehicle electric devices are connected includes one transmitter-receiver and a plurality of electrical device controllers. The one transmitter-receiver is mounted on the vehicle, is connected to the central control unit in a wired manner and includes and antenna for transmitting/receiving therethrough a signal in a wireless manner. The plurality of electric device controllers are provided in on-to-one correspondence to the plurality of on-vehicle electric devices. Each of the electric device controllers includes and antenna for transmitting/receiving therethrough a signal to/from the transmitter-receiver in a wireless manner as to control corresponding one of the on-vehicle electric devices on the basis of the received signal or to process a signal generated by the corresponding one of the on-vehicle electric devices to transmit the processed signal to the transmitter-receiver.

17. A power supply controller, which is connected in one-to-one correspondence to an electric device, for changing ON/OFF of supply of an electric power to the electric device in accordance with a control signal issued from a central control unit, wherein, in a case that the power supply receives a signal from the central control unit, a WARD signal, an identification signal of the electric device as an object of control and a control signal used to control the electric device are discriminated from the received signal and that the electric device specified with the identification signal is the connected electric device, then the power supply outputs a reset signal used to reset the electric device to be controlled before outputting predetermined control information based on the control signal.
