HYBRID METHOD AND APPARATUS FOR DETECTING A VEHICLE/PEDESTRIAN IMPACT

摘要

An apparatus detects a vehicle/pedestrian impact event by sensing impact events near a forward location of a vehicle using both acceleration sensors and pressure sensors and providing associated signals indicative thereof, determining metric values for each of the sensor signals, and determining if a vehicle/pedestrian impact has occurred in response to the determined metric values

主权项

1. An apparatus for detecting a vehicle/pedestrian impact comprising:
a least one acceleration sensor mounted near a forward location of a vehicle for providing an associated acceleration signal indicative of an impact event; at least one pressure sensor mounted near the forward location of the vehicle for providing an associated pressure signal indicative of an impact event; and a controller for determining if a vehicle/pedestrian impact event has occurred in response to the acceleration signal and the pressure signal and for providing an actuation control signal in response thereto.
