CRASH SENSOR SYSTEM AND METHOD FOR A VEHICLE
First Claim
1. A crash sensor system for a vehicle, the system comprising:
- a vehicle frame member that includes at least one cavity;
at least one pressure sensor coupled to the vehicle frame member, the at least one pressure sensor being configured to generate a pressure signal indicative of a pressure change within the cavity; and
a controller configured to;
receive the pressure signal;
compare the pressure signal to a predetermined pressure threshold; and
determine an occurrence of a frontal impact crash in response to the pressure signal exceeding the predetermined pressure threshold.

Abstract
A crash sensor system and method used for determining when a vehicle is involved in a frontal impact crash. The crash sensor system including at least one pressure sensor coupled to a vehicle frame member. The vehicle frame member having a cavity and the at least one pressure sensor being configured to generate a pressure signal indicative of a pressure change within the cavity. The crash sensor system further including a controller configured to compare the received pressure signal against a predetermined pressure threshold. The controller also being configured to determine that a frontal impact crash has occurred when the pressure signal exceeds the predetermined pressure threshold.
