ABSTRACT:
A cruise control apparatus for a vehicle is disclosed which is highly reliable in operation and in which a target speed stored can be checked, and if there is any error in the stored target speed, cruise control is automatically inhibited or cancelled. In one embodiment, the vehicle speed sensed by a speed sensor is stored in a first area of a RAM as a first target speed and in a second area as a second target speed. A comparator compares the first target speed and the second target speed and outputs either one of the target speeds as a final target speed if the target speeds are equal to each other but outputs the lower one of the target speeds as the final target speed if there is disagreement therebetween. A cruise controller connected to receive the output of the comparator is adapted to be externally set into operation for controlling a throttle actuator in such a manner that a throttle valve is moved to a target degree of opening which corresponds to the final target speed. If there is disagreement between the first and second target speeds, the cruise controller is inhibited from being set into operation once cruise control has been cancelled. In another embodiment, the cruise control operation of the cruise controller is automatically cancelled if there is disagreement between the first and second target speeds.
