Abstract
A vehicle constant-speed cruising device, in which, with respect to the pulse width of a pulse signal for an actuator adapted to operate an engine throttle valve, acceleration and deceleration signals given during a predetermined past period of time are stored, to estimate cable-layout hysteresis and correct it. Thereby, the vehicle speed is improved in maintenance and in convergence, thus making it comfortable to ride in the vehicle.
