Abstract
A sensing and injury mitigation system for a vehicle to identify an object in an impact event is disclosed. The system includes an impact sensing unit comprising an impact sensor and a pressure sensing unit. The impact sensor has fluid-filled first and second tube portions. The pressure sensing unit has a housing and first and second pressure sensors located within the housing. The first tube portion of the impact sensor is attached to the first pressure sensor and the second tube portion of the impact sensor is attached to the second pressure sensor. The pressure sensing unit senses changes in fluid pressure within the tubes. In one embodiment, the tube portions of the impact sensor define a loop. In another embodiment, at least a portion of the first tube portion and at least a portion of the second tube portion share a common axis.
