More Information
Summary:An ECU of a vehicle controls a motor on the vehicle. The ECU includes a microcomputer and a monitoring circuit. The monitoring circuit includes a rotation detection circuit that detects the number of rotations of the motor at a preset sampling interval, a control circuit including a logic circuit that controls an operation of the rotation detection circuit, and an inspection circuit that inspects of the control circuit. The microcomputer is started upon start of vehicle power supply and performs a specific process using the number of rotations of the motor detected by the rotation detection circuit. The inspection circuit performs the inspection of the control circuit in the monitoring circuit in a period in which the microcomputer is kept in a reset state after the vehicle power supply is turned on and which is within a sampling interval of the rotation detection circuit in the monitoring circuit.
