Abstract
Devices and methods for controlling accident protection triggering devices in motor vehicles when there is a risk of a rollover of the vehicles determine a transverse measured value characteristic of the transverse acceleration from a transverse sensor in combination with a transverse tilt of the vehicle. Wheel rpm values of the wheels of the vehicle are determined from wheel rpm sensors. A transverse acceleration value that is exclusively characteristic of the transverse acceleration of the vehicle is calculated by a control device connected with these sensors from the rpm values. The transverse measured value is corrected in such fashion that a transverse tilt value is calculated therefrom that is exclusively characteristic of the transverse tilt, with accident protection triggering devices being actuated as a function of the transverse tilt value by the control device.
