Abstract
An apparatus for activating occupant restraint devices of a vehicle includes first and second sensors, first and second determination units, an output circuit, and an activation unit. The first sensor generates a first signal indicative of dynamic movement of the vehicle, and the first determination unit determines, using a CPU, whether or not to output a first activation signal depending on the first signal. The second sensor generates a second signal indicative of the dynamic movement of the vehicle, and the second determination unit determines, using two thresholds of deceleration and acceleration or a single selectively provided deceleration threshold, whether or not to output a second activation signal depending on the second signal. The output circuit outputs a final activation signal upon receiving both the first and second activation signals, and the activation unit activates the occupant restraint devices of the vehicle upon receiving the final activation signal.
