Claims

[Scope of utility model registration request]

A speed sensor that detects the vehicle speed, a control switch that changes the control mode, a means for controlling the throttle valve, a throttle opening sensor that converts the throttle valve opening into a pulse amount, the speed sensor, the control switch, and the throttle. a control section that calculates and generates a control signal for driving at a constant speed according to a predetermined speed control pattern based on the output signal from the opening sensor; A control pattern program is provided in which the relationship is memorized in advance, and the throttle opening is set according to the set vehicle speed the moment the vehicle starts running at a constant speed, and the throttle opening is held constant until the current vehicle speed and the set vehicle speed become equal. A constant speed driving control device for an automobile characterized by the following.
