ABSTRACT:
A cruise control apparatus for a vehicle which is highly reliable and safe in operation. The cruise control apparatus includes a cruise control setting switch for setting cruise control; a first switch operatively connected with the brake system in such a manner that it turns on and off the power supply to a throttle actuator, which acts to control the opening degree of a throttle valve, in response to brake release and application, respectively; and a second switch for cancelling the setting of cruise control. The cruise control apparatus determines whether there is a fault in either one of the first and second switches which continues for more than a predetermined time when the vehicle is travelling at a speed higher than a predetermined level, and it inhibits the cruise control setting switch from setting cruise control when there is such a fault.
