System and method for deploying a safety system
First Claim
1. A method for deploying a vehicle safety system in a vehicle, the method comprising:
- receiving at least two front acceleration signals indicative of acceleration along a longitudinal axis about a front end of the vehicle;
receiving a longitudinal acceleration signal indicative of acceleration along a longitudinal axis about a center of gravity of the vehicle;
upon a determination that the front acceleration signals and the longitudinal acceleration signal exceed a front crash threshold, determining a rotational value indicative of rotational velocity about an axis of the vehicle that is normal to a surface of a road; and
deploying a vehicle safety system including deploying at least a front safety system based in part upon the rotational value.

Abstract
A system and method are provided for deploying a safety system when a vehicle involved in a front crash may be experiencing rotational velocity. The vehicle may include a number of acceleration and rotational sensors. The vehicle may further include a controller that may be configured to determine if the vehicle is involved in a frontal crash using a combination of the acceleration and rotational sensors. The controller may also be configured to determine if the vehicle experiences rotational energy during the frontal crash using a combination of the acceleration and rotational sensors. The controller may also be configured to deploy vehicle safety systems, including at least one side safety system, if it is determined that the vehicle is involved in a frontal crash and the vehicle is experiencing rotational energy.
