Abstract
A control device for vehicles includes a microcomputer having an output port which outputs a signal in a normal operating state of the microcomputer, and two electronic circuits associated with the microcomputer. The two electronic circuits operate to change a control mode for the vehicle to a fallback mode upon occurrence of a malfunction or misoperation in the microcomputer thereby to prevent the vehicle from operating in a dangerous running condition caused by erroneous control due to the misoperation by the microcomputer.
