<p>A forward object sensor (50) includes a plurality of stationary on-road object recognizing units (13b, 13c, 13d, 13e, 13f). The stationary on-road object recognizing units (13b, 13c, 13d, 13e, 13f) recognize a forward object as a stationary on-road object when a preceding vehicle has passed over the forward object, when a preceding vehicle is located ahead of the forward object, when the vehicle (100) is travelling at a speed higher than a predetermined speed and the forward object is located between two other objects, when it is not until the vehicle (100) comes close to the forward object that the forward object is detected, and when the strength of a reflected wave from the forward object monotonically increases until the distance between the forward object and the vehicle (100) reaches a predetermined value and monotonically decreases when the distance falls below the predetermined value, respectively.</p> |
