Abstract:
Even in a case where an operation abnormality occurs in the arithmetic processing unit of the control device, control is safely shifted to the degeneration control microcomputer, and a vehicle control device capable of improving safety is realized.
There are provided an outside world recognition microcomputer 10b, a control microcomputer 11b that outputs a control command to the actuator control device, and a degeneration control microcomputer 12b to which control is shifted in a case where an abnormality occurs in the control microcomputer 11b. The outside world recognition microcomputer 10b calculates a collision potential based on information from the outside world, and determines whether to reset the control microcomputer 11b when an abnormality occurs in the control microcomputer 11b or to shift control to the degeneration control microcomputer 12b.
