Patent number: 6856868Abstract: A rollover detection system (12) for an automotive vehicle (10) includes a controller (14) that is hooked to various types of sensors. The sensors may include a lateral acceleration sensor and another sensor or combination of sensors that gives an indication to another lateral condition of the vehicle.
