A vehicle rollover event detector ( ) includes a rollover sensor ( ). A first accelerometer ( ) senses vehicle acceleration in a direction offset from the front-to-rear axis of the vehicle ( ) up to a maximum acceleration sensing level and provides a first acceleration signal indicative thereof. A second accelerometer ( ) senses vehicle acceleration in the offset direction at acceleration levels in excess of the maximum acceleration sensing level of the first accelerometer and provides a second acceleration signal indicative thereof. A controller ( ) selects the first accelerometer or second accelerometer and provides an actuation signal ( ) when the signal from the rollover sensor and the selected first or second accelerometers both indicate a vehicle rollover event.

Apparatus and method for detecting vehicle rollover having a discriminating safing function

A rollover sensing system ( ) includes a roll rate sensor ( ) operative to sense a roll rate of rotation of a vehicle ( ) and to provide a roll rate signal having an electrical characteristic indicative thereof. A controller ( ) is connected to the roll rate sensor ( ) and is operative to determine a roll angle of the vehicle ( ) based on the roll rate signal. The controller ( ) includes a threshold having a value functionally related to roll angle. The controller ( ) determines the occurrence of a vehicle rollover condition in response to the sensed roll rate crossing the threshold.

System and method for sensing vehicle rollover

An apparatus ( ) for controlling an actuatable side restraining device ( ) of a vehicle ( ) includes crash sensors ( ) sensing a vehicle crash condition and providing associated crash sensor signals ( ) indicative thereof. An actuator controller ( ) enables actuation of the actuatable side restraining device ( ) in response to enhanced discrimination and safing determinations.

Method and apparatus for controlling an occupant side restraining device with enhanced side safing function

A vehicle rollover event detector ( ) includes an accelerometer ( ) that senses vehicle acceleration in a direction offset from a front-to-rear axis of the vehicle ( ) and provides an acceleration signal ( ) indicative thereof. A rollover sensor ( ) senses vehicle roll and provides a roll signal ( ) indicative of vehicle roll about the front-to-rear axis of the vehicle. A controller ( ) compares the roll signal ( ) against a first rollover threshold ( ) when the acceleration signal ( ) is less than an acceleration threshold ( ) and compares the roll signal ( ) against a second rollover threshold ( ) when the acceleration signal ( ) is equal to or greater than the acceleration threshold ( ) and for indicating a vehicle rollover condition when the roll signal is greater than the threshold ( ) it is compared against.
