Method and apparatus for detecting pedestrian vehicle impact

摘要

An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.

1. An apparatus for detecting a pedestrian/vehicle impact comprising:
a plurality of sensors mounted near a forward location of a vehicle, each sensor providing an associated signal indicative of an impact event; a metric determining device for determining metric values for each of the sensor signals; a controller for determining if any of said determined metric values indicates the occurrence of a misuse event, said controller further determining the occurrence of a pedestrian/vehicle impact event by comparing the metric value of at least one sensor signal against a selectable threshold and providing an actuation signal in response to said comparison, the selectable threshold being selected in response to the determined occurrence of a misuse event; and an actuatable impact mitigation device attached to the vehicle and being responsive to said actuation signal from said controller.
