Abstract
Upon an occurrence of a failure in the throttle valve driving system of an engine provided with a throttle actuator 7, a vehicle control device for controlling the output power of the engine disables some of the cylinders (1) in accordance with the outputs of the acceleration pedal position sensor 61 and the throttle position sensor 17 when the vehicle is being driven (i.e., when the transmission is not in the neutral or the parking position), and (2) in accordance with the output of the throttle position sensor 17 when the vehicle is stopped (i.e., when the transmission is in the neutral or the parking position). Further, the vehicle control device effects fuel cut when the rpm of the engine exceeds a predetermined level. Thus, even upon an occurrence of a failure in the throttle valve drive system, the output power of the engine can be safely controlled solely by means of the acceleration pedal when the vehicle is driven, and is regulated to an appropriate level when the vehicle is stopped. An occurrence of a failure in the throttle valve driving system is detected, for example, when the position of the throttle valve 5 detected by the throttle position sensor 17 deviates from the target position thereof.
