VEHICLE CONTROL DEVICE AND ELECTRONIC CONTROL SYSTEM

Implemented is a highly reliable vehicle control device capable of performing control transition safely to a degeneration control microcomputer even if an operation abnormality occurs in a control microcomputer in a vehicle control device. Provided are: a control microcomputer that outputs a control command to an actuator control device; and a degeneration control microcomputer for control transition when an abnormality is detected in the control microcomputer . When transitioning to the degeneration control microcomputer when detecting the abnormality in the control microcomputer , the control microcomputer is notified of the abnormality of the control microcomputer , and the control microcomputer is reset after the required transition period of the degeneration control microcomputer has elapsed and the degeneration control has started. As a result, a control blank period is eliminated.
