1. An apparatus for controlling a vehicle actuatable occupant restraining system comprising:
- a central crash accelerometer sensing crash acceleration at a central vehicle location and providing a first crash acceleration signal indicative thereof;
a side-satellite accelerometer sensing crash acceleration substantially parallel with a front-to-rear axis of the vehicle and for providing a signal indicative thereof; and
a controller actuating the actuatable occupant restraining system in response to the central crash acceleration signal and the side-satellite signal.

Abstract
An apparatus is provided for controlling a vehicle actuatable occupant restraining system. A central crash accelerometer senses crash acceleration at a central vehicle location provides a first crash acceleration signal. A side-satellite accelerometer senses crash acceleration substantially parallel with a front-to-rear axis of the vehicle and provides a signal indicative thereof. A controller actuates the actuatable occupant restraining system in response to the central crash acceleration signal and the side-satellite signal.

13. An apparatus for controlling an actuatable occupant restraining system of a vehicle, the apparatus comprising:
-
a first sensor located at a central vehicle location for sensing crash acceleration of the vehicle in a direction generally parallel to a longitudinal axis of the vehicle and providing first signals indicative thereof;
a second sensor located remote from the first sensor and adjacent a side of the vehicle, the second sensor configured to sense crash acceleration in a direction generally parallel to a longitudinal axis of the vehicle and in a direction transverse to the longitudinal axis of the vehicle and to provide second signals indicative thereof; and
a controller for actuating the actuatable occupant restraining system in response to the first and second signals. - View Dependent Claims (14, 15, 16)
