Abstract
The collision of a vehicle with a pedestrian is detected by the presence of a foreign object in a sensing zone above the hood of the vehicle within a prescribed time of an initial impact with the bumper of the vehicle. The initial impact is detected with an acceleration sensor disposed in or near the front bumper and the sensing zone is defined by object detection sensors disposed on the hood or behind the windshield of the vehicle. Vehicle speed is used to discriminate against events that occur while the vehicle is stationary or moving very slowly.
