Abstract
A crash sensor system includes an electronic control unit (ECU). The ECU has an accelerometer to measure longitudinal acceleration of the vehicle. Front crash satellite sensors are mounted at the front of the vehicle to detect a front or a rear crash event. When a front or rear crash event occurs, the first accelerometer is utilized to determine if the crash occurred at the front or the rear of the vehicle, regardless of the polarity of the front crash satellite sensors.
