<p>A radar (11) transmits electromagnetic waves at predetermined time intervals in order to scan a predetermined angular range surrounding the own vehicle in the horizontal direction, and, when the reflected waves of the electromagnetic waves reflected off an object are received, the points on the object where the electromagnetic waves are reflected are detected based on the reception results of the reflected waves, whether a parking space (Sp) is available or not is judged based on the prestored body dimension data of the own vehicle and the arrangement of reflection points, and further whether a vehicle can be parked in the parking space (Sp) or not is judged. Since a judgment is made as to whether a vehicle can be parked or not based on the width (Wx) of the road and the width (Wy) of the parking space (Sp) calculated based on the arrangement of reflection points, a judgment can be made more precisely as to whether a vehicle can be parked in the parking space (Sp) or not.</p> |
