Vehicle side impact detection using vehicle yaw

A safety system for a motor vehicle includes a sensor suite detecting a lateral impact and a vehicle yaw, an occupant safety system, and a control module receiving signals from the sensor suite. The control module activates the occupant safety system if either: a) an impact magnitude detected by the...

Summary:A safety system for a motor vehicle includes a sensor suite detecting a lateral impact and a vehicle yaw, an occupant safety system, and a control module receiving signals from the sensor suite. The control module activates the occupant safety system if either: a) an impact magnitude detected by the sensor suite is greater than a first impact threshold and a vehicle yaw magnitude detected by the sensor suite is greater than a yaw threshold; or b) the impact magnitude is greater than a second impact threshold higher than the first impact threshold. The system may be operated to determine a longitudinal location of the impact on the vehicle by comparing a magnitude of the impact and a magnitude of the vehicle yaw. The occupant safety system may then be activated in a mode based upon the longitudinal location of the impact and/or appropriate for a spinning vehicle.
