Kind Code:
B2
Abstract:
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 11b that outputs a control command to an actuator control device; and a degeneration control microcomputer 12b for control transition when an abnormality is detected in the control microcomputer 111b. When transitioning to the degeneration control microcomputer 12b when detecting the abnormality in the control microcomputer 11b, the control microcomputer 12b is notified of the abnormality of the control microcomputer 11b, and the control microcomputer 11b is reset after the required transition period of the degeneration control microcomputer 12b has elapsed and the degeneration control has started. As a result, a control blank period is eliminated.
