    摘要： A system and method of activating a restraint system of a vehicle is described. The method includes generating a vehicle speed signal that represents a longitudinal speed of a vehicle, generating a lateral acceleration signal that represents a lateral acceleration of the vehicle, filtering the lateral acceleration signal to generate a filtered lateral acceleration signal, comparing the filtered lateral acceleration signal to a predetermined lateral acceleration enable threshold, estimating a lateral speed of the vehicle based on the vehicle speed signal when the filtered lateral acceleration exceeds the predetermined lateral acceleration enable threshold, and activating a restraint system of the vehicle based in part on the estimated lateral velocity.

    摘要： A method of operating a load limiting restraint system including the steps of receiving an acceleration value and also receiving a signal indicative of an occupant size. The signal received of occupant size is combined with the acceleration value to predict a load on the occupant and the restraint system. If the predicted load exceeds a predicted load value then the load limiting device is actuated to gradually reduce and selectively release the seatbelt.

    摘要： Disclosed is a method to determine a vehicle's lateral velocity during abnormal driving situations of a vehicle during controlled side-impact or rollover crash tests that involve the pulling of a vehicle sideways into an object. A high-resolution, low-range, lateral accelerometer is integrated to determine the lateral velocity. Furthermore, is a method to initiate the integration of the acceleration signal and a method to stop and reset the integration. The method recognizes special conditions associated with abnormal driving situations like controlled crash tests, and therefore will not be active during normal operating conditions. The method also includes a means to handle offset tolerances associated with accelerometers by finding the sensor's zero-g point while the vehicle is at rest.
