ABSTRACT:
When the ETV control system runs into trouble, drivability and safety are secured against the system trouble by fixing the step of speed change at a high speed position if the vehicle is running forward or stopping fuel feed to a specific cylinder or cylinders if it is running backward. When the electronic throttle control system runs into trouble, the throttle valve 3 is released from control by stopping power supply to the motor 1, the throttle value 3 is mechanically fixed in a preset position, and the transmission 2 is fixed in a high speed position if the vehicle is running forward, thereby to reduce engine acceleration and the shock to the body due to unnecessary speed change action, or fuel feed to a specific cylinder or cylinders is stopped according to the engine condition if the vehicle is running backward, thereby to reduce the engine output, so that the vehicle be enabled to run smoothly.
