Abstract
An apparatus and method for deployment of an air bag installed in an automotive vehicle. The control includes a senor for sensing vehicle deceleration due to a collision and a processor operatively connected to the sensor. The sensor generates a deceleration signal which is analyzed by the processor. The processor calculates velocity and signal energy from the deceleration signal, and compares the velocity and signal energy to predefined velocity and energy thresholds, respectively. The processor also generates a deployment signal when both the velocity and energy signals exceed the respective thresholds. In the method for controlling the deployment of an air bag, vehicle deceleration due to a collision is sensed and a deceleration signal is generated therefrom. The velocity signal and energy signals are then calculated and compared to the respective predefined velocity and energy thresholds. If the velocity signal exceeds the velocity threshold and the signal energy exceeds the energy threshold, a deployment signal is generated.
