PURPOSE: To prevent repetition of regulation of a car speed, i.e. the occurrence of surge, by a method wherein, during control of constant speed running and when the opening of a throttle valve is reduced to a given value or less, the higher the degree of accelerating of a car speed is, the more the number of fuel injection valves being brought into a rest state is.
CONSTITUTION: A title device is provided with an actuator 9 controlling rotation of a throttle valve 6, and a means A controlling drive of the actuator 9 so that a car speed is regulated to a target value. Further, it is provided with a means B detecting the degree of accelerating of a car speed, and a means C detecting the opening of the throttle valve 6. A fuel feed control means D is provided for bringing fuel injection valves 81W84 into a rest state during control of constant speed running by means of the actuator control means A and when the opening of the throttle valve 6 is reduced to a given value of less. In this case, in the fuel feed control means D, the higher the degree of accelerating is, the number of the fuel injection valves being brought into a rest state is increased. This constitution prevents the occurrence of surge when a vehicle is running on a down slope as constant speed running is controlled.
