    摘要: A method is presented for rollover detection, taking into account the transverse vehicle acceleration and transverse vehicle velocity and at least one rotational state quantity about the driving direction axis, wherein a correction parameter for the transverse vehicle velocity and/or transverse vehicle acceleration is determined by determining a translational energy value from the transverse vehicle velocity and a rotational energy value from the rotational state quantity and the correction parameter from the energy values.

    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.

    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.
