System and method for determining when to deploy a vehicle safety system
First Claim
1. A system for determining when to deploy a deployable vehicle safety system, the system comprising:
- a processor;
a single inertial sensor, the inertial sensor producing both a first output and a second output, the first output having a longer group delay than the second output and the second output having a shorter group delay than the first output, wherein the second output is supplied to the processor and provides inertial information for the deployable vehicle safety system, and the first output is supplied to the processor and provides inertial information for a vehicle stability control system;
where the processor is configured to use the first output for stability control of the vehicle;
wherein the processor is configured to monitor the second output of the inertial sensor to determine if the inertial information from the second output indicates that the vehicle has been in a collision; and
wherein the processor is configured to deploy the deployable vehicle safety system upon determining based on the inertial information from the second output that the vehicle has been in a collision.

Abstract
A system and method for determining when to deploy a vehicle safety system includes a processor and inertial sensor. The inertial sensor has a filtered output and an unfiltered or lightly filtered output. The unfiltered or lightly filtered output is in communication with the processor and provides inertial information relating to the vehicle. The filtered output of the inertial sensor is in communication with a vehicle stability control system. The processor is further configured to monitor the unfiltered or lightly filtered output of the inertial sensor and determine if the inertial information indicates that the vehicle has been involved in a collision. If the vehicle has been involved in a collision, the processor is configured to deploy a vehicle safety system.
