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.

Hybrid method and apparatus for detecting a vehicle/pedestrian impact

An apparatus detects a vehicle/pedestrian impact event by sensing impact events near a forward location of a vehicle using a multi-port pressure sensor and acceleration sensors. The multi-port pressure sensor includes multiple pressure sensors in a unified housing, connected via individual pressure ports to multiple impact-sensing hoses mounted along the vehicle bumper. An acceleration sensor may also be installed in the same housing. A single electrical connector provides connection to the multiple pressure sensors and also the acceleration sensors.

An apparatus () detects a pedestrian/vehicle impact, the apparatus including 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 () determines metric values for each of the sensor signals. A controller () 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 () is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.
