Claims

[Scope of claim for utility model registration] A steering phase signal that controls the front wheels and rear wheels to be in the same phase or opposite phase depending on the driving condition based on steering wheel operation, and a steering angle that corresponds to the steering angle of the steering wheel. It is equipped with a four-wheel steering control device that outputs a signal, and also inputs a vehicle speed signal from a vehicle speed sensor that detects vehicle speed, and controls the opening and closing of a throttle valve via an actuator to maintain the set vehicle speed for constant speed driving. A constant speed traveling device for a four-wheel steering vehicle that performs the above-mentioned four-wheel steering control device, the steering phase determining means receiving steering phase signals from the four-wheel steering control device and determining whether or not they are the same phase control signals. , a set vehicle speed reducing means for reducing the set vehicle speed in response to the steering angle signal when the steering phase signal is determined to be an opposite phase control signal by the steering phase determining means. Constant speed running device for 4-wheeled vehicles.
