1. A system for detecting impact events for a vehicle, the system comprising:
- a pressure sensor positioned in a first impact zone of the vehicle, the at least one pressure sensor being configured to generate a pressure signal corresponding to a measured pressure reading within the first impact zone; and
a controller positioned within the vehicle and configured to integrate the pressure signal over time to determine the occurrence of a vehicle impact event at the first impact zone.

Abstract
A system for detecting impact events for a vehicle is provided. The system comprises a pressure sensor and a controller. The pressure sensor is positioned in a first impact zone of the vehicle and is configured to generate a pressure signal corresponding to a measured pressure reading within the first impact zone. The controller is positioned within the vehicle and is configured to integrate the pressure signal over time to determine the occurrence of a vehicle impact event at the first impact zone.

16. A system for detecting side impact events for a vehicle, the system comprising:
-
a first pressure sensor positioned about a front driver side of the vehicle, the first pressure sensor being configured to generate a first pressure signal corresponding to a measured pressure reading within the front driver side of the vehicle; a second pressure sensor positioned about a front-passenger side of the vehicle, the second pressure sensor being configured to generate a second pressure signal corresponding to a measured pressure reading within the front passenger side of the vehicle; and a controller positioned within the vehicle and configured to integrate the first and the second pressure signals over time to generate first and second integrated pressure signals, respectively, and to determine the occurrence of a vehicle side impact event at one or more the front driver side and the front passenger side of the vehicle based on the first and the second integrated pressure signals. - View Dependent Claims (17, 18, 19, 20)
