Claims

[Scope of utility model registration request]

An acceleration/deceleration detection circuit that detects that a change in vehicle speed is within a predetermined range in a vehicle constant speed traveling device that controls the throttle valve opening of an engine to maintain an arbitrarily set vehicle speed; , a steering sensor that detects a steering angle and outputs an electrical signal according to the steering angle; and a signal from the steering sensor is input to detect that a change in the steering angle is within a predetermined range. When the steering holding state detection circuit, the acceleration/deceleration detection circuit, and the steering holding state detection circuit both output detection signals, constant speed running control is started at the vehicle speed at that time, and at least one of the detection signals is not output. A constant speed traveling device for a vehicle, comprising: a command circuit for canceling constant speed traveling control;
