Abstract:
In a method for estimating the height of the center of gravity of a vehicle, a lateral acceleration is determined. Predefined first and second driving situation are detected at a first time as a function of a determined roll rate or of a determined roll angle and at a second time as a function of the roll rate or of the roll angle. In a time period delimited by the first and second times, a differential angle by which a vehicle body tilts during the time period is determined. Also determined are an angular speed: formula and an angular acceleration: formula of the vehicle tilting movement in the time period. A height of the center of gravity of the vehicle is estimated on the basis of an equation of motion as a function of the lateral acceleration, of the differential angle, of the angular speed: formula and of the angular acceleration: formula.
