Abstract
An ECU having a microcomputer for controlling a control object includes: a detection device that detects an anomalous operation of the microcomputer; a first reset device that outputs a reset signal for the microcomputer when the detection device detects the anomalous operation; a failsafe control device that executes a failsafe control operation for controlling the control object to be safer than the control object before resetting the microcomputer when the microcomputer is reset to a normal state; a counting device that counts a number of times of occurrence of the anomalous operation when the detection device detects the anomalous operation again after the failsafe control device starts to execute the failsafe control operation; and a second reset device that outputs the reset signal and holds an output of the reset signal when the number of times of occurrence reaches a predetermined number of times.
