Abstract
In a method for determining the lateral acceleration of a motor vehicle, the lateral acceleration is calculated from signals of a wheel sensor and a load sensor. Since in many cases these sensors are already present on the vehicle, e.g., for chassis control, additional sensors are not necessary. The values for the lateral acceleration thus ascertained may then be used in further devices, such as for a vehicle dynamics controller or a device for preventing tipping. For example, usable as a load sensor in the case of a pneumatic suspension is also a pressure sensor which measures the pressure within the pressure bellows of the pneumatic suspension and supplies a signal, corresponding to the mass or the axle load, to the control. The lateral acceleration may be determined with the aid of a steering-angle sensor.
