Abstract
A method for rollover detection for automotive vehicles with safety-related devices, such as roll bars, (side) airbags and seat-belt tensioners involves the following steps and features. An angular rate of rotation (&ohgr; ) around the vehicle longitudinal axis is provided by the signal of a gyrosensor, and an initial position angle (&agr; ) identifying the initial position of the vehicle transverse axis is determined from at least one sensor signal. An integral of the angular rate is added to the initial position angle. The absolute value of the resulting sum, which is proportional to the momentary inclination angle relative to the horizontal plane, is then compared to a trigger threshold that is a function of the angular rate and vehicle-specific parameters. A safety-related device is triggered if the absolute value of the resulting sum exceeds the trigger threshold.
