A constant-speed control device for a vehicle including a fuel cut device and a suspending device which suspends a fuel cut operation. An actuator is provided for controlling a throttle valve so that the vehicle runs at a constant speed. The fuel cut device carries out a fuel cut when the degree of opening of the throttle valve is smaller than a predetermined value. The suspending device suspends operation of the fuel cut device until the vehicle speed becomes higher than a target value by a predetermined value.

A constant-speed control device for a vehicle, said device controlling a throttle valve provided in an intake passage of an internal combustion engine so that said vehicle runs at a constant speed set by a driver, said device comprising: an actuator controlling the degree of opening of said throttle valve; means for controlling said actuator in accordance with the vehicle speed to obtain constant-speed control; means for sensing the degree of opening of said throttle valve; means for supplying fuel to said engine; means for preventing a fuel supply by said fuel supply means when the degree of opening of said throttle valve is smaller than a predetermined value; and means for suspending operation of said fuel supply prevention means in relation to a difference between the vehicle speed and a driver set constant-speed control target speed, during control of said actuator to obtain constant-speed control, whereby sudden increases and decreases in the vehicle speed about the constant speed-control target speed are reduced.
