PROBLEM TO BE SOLVED: To greatly reduce power consumption by optimum control of power supply for each ECU connected to a communication network.SOLUTION: A transceiver/receiver 13 converts a differential signal message received through a CAN bus Bc to a digital signal. A select circuit 14 determines whether the converted message is in a CAN format or a UART format, and outputs the message to a UART circuit 15 if the format is a UART format. The UART circuit 15 determines if the message matches with the UART format. If it matches, an ID determination circuit 16 determines whether an inputted message designates an own ECU CAN ID or not. If the CAN ID designates the own ECU, the ID determination circuit 16 outputs an enable signal EN, and turns on a regulator 4 to supply power to an MCU 5 and an actuator Ac.SELECTED DRAWING: Figure 2 |
