Abstract
Distance sensors are mounted on both ends of a vehicle and have light transmitting and receiving sections. A distance to an object is independently measured by alternately transmitting 'one-side-only enlarged light beams' at a time interval and receiving corresponding reflected beams from the object. In an overlapped area of the 'one-side-only enlarged light beams', the distance from the vehicle to the object, as well as the azimuth of the object, is measured by a triangulation distance measurement using an interval between the distance sensors as a baseline. The lengths of the 'one-side-only enlarged light beams' in the running direction of the vehicle are about 50m and a width vertical to the running direction of the overlapped area is about 2m slightly greater than a width of the vehicle.
