Patent ID: 8019511

Claim:
A system for detecting a rollover of a vehicle that includes at least one wheel reaction force sensing device positioned about at least one wheel of the vehicle for transmitting wheel reaction force signals indicative of an amount of force exerted on the at least one of the wheels of the vehicle, the system comprising: a controller operably coupled to the at least one wheel reaction force sensing device and including at least one accelerometer sensor for transmitting acceleration signals indicative of vehicle body accelerations about at least one axis of the vehicle, the controller being configured to: determine a first force index in response to the wheel reaction force signals; determine a first lateral acceleration of the vehicle in response to the acceleration signals; compare the first force index to a threshold force index and the first lateral acceleration to a threshold lateral acceleration; and deploy a restraint system based on a comparison of the first force index to the threshold force index and the lateral acceleration to the threshold lateral acceleration.
