Abstract: A main body ECU as a slave node includes a switch. The switch is under OFF state when a prohibition signal is outputted from a verification ECU as a master node and under ON state when the prohibition signal is not outputted. The switch is inserted in a reception path between a receive port of a microcomputer of the main body ECU and a receiver of a transceiver that is connected with a communication bus. When the switch is under OFF state, a reception signal outputted by the transceiver is not inputted into the microcomputer of the main body ECU. Therefore, the microcomputer is not activated even if an activation frame is transmitted to the communication bus; this enables the main body ECU to maintain a sleep mode.

Abstract: An electronic control unit includes a microcomputer and a power circuit that supplies an electric power to the microcomputer. The microcomputer and the power circuit respectively operate in a normal operation mode and in a low power operation mode that consumes less power than the normal operation mode. The electronic control unit further includes a mode switcher for switching the operation modes of the microcomputer and the power circuit according to an input signal from an external device. When a mode switch signal for switching the operation mode of both devices to the normal operation mode, the mode switcher first switches the power circuit to the normal operation mode and subsequently switches the microcomputer to the normal operation mode, which prevents a reset operation of the microcomputer without using a large capacity capacitor.

Abstract: A controller includes a microcomputer that operates in a normal mode or in a low power mode and communicates with an external device, a monitor circuit that monitors an operation state of the microcomputer based on a monitor signal output from the microcomputer, and a start circuit that controls a drive of the monitor circuit. Communication signals exchanged between the microcomputer and the external device include a dominant state and a recessive state, and the start circuit monitors the communication signals. When the communication signals in the low power mode of the microcomputer include the dominant state, the start circuit puts the monitor circuit in a monitoring state. When no monitor signal is input from the microcomputer to the monitor circuit that is operating in the monitoring state, the monitor circuit determines that an abnormality has occurred in the microcomputer.

The arithmetic section acquires a plurality of sensor signals, which is transmitted from a sensor, converted from an analog signal to a digital signal by the AD conversion section, and filtered by the filter section, in a term before and after receiving the data acquisition timing signal and generates a data synchronized with the data acquisition timing signal.
