ABSTRACT:
An automatic driving system for a motor vehicle has a main actuator for operating a main throttle valve, an auxiliary actuator for operating an auxiliary throttle valve, and sensors for detecting driving conditions of a present motor vehicle and for producing driving condition signals. A failure of the automatic driving system is determined based on the driving condition signals. In response to the determined failure, the main and auxiliary actuators are operated so as to close the main and auxiliary throttle valves.
