ABSTRACT:
A cruise control apparatus for a vehicle is disclosed which is free from influences resulting from variations in the ground voltage level as well as variations in the voltage in the power supply so as to effectively prevent malfunctions of the apparatus and hence enhance reliability in operation. To this end, the cruise control apparatus includes cruise control switches such as a cancellation switch, a set/coast switch, a resume/acceleration switch, etc., which are provided on the steering wheel of the vehicle and which are connected in parallel with each other. The cruise control switches have an output terminal and an input terminal, the switches being selectively operated to change the output voltage at the output terminal so as to provide a plurality of command signals for cruise control. A control unit is connected to the output terminal of the cruise control switches through the intermediary of a slip ring for performing a cruise control operation in response to the cruise control command signals. A power supply is commonly connected to the input terminal of the cruise control switches and the control unit.
