Method for combined determination of vehicle current roll angle and current road transverse slope of curved road section driven by motor vehicle, involves calculating vehicle current roll angle from current lateral acceleration of vehicle

摘要

The method involves determining current road transverse slope (phi-fb) and the current vehicle roll angle (phi-a) from the chassis data and transverse dynamics data of a motor vehicle (1). The current vehicle roll angle is calculated from the current lateral acceleration (a-y), the current speed (v-x) and the current yaw speed of the motor vehicle. The current road transverse slope is calculated from the current vehicle roll angle, a current chassis roll angle (w) and a current tire roll angle. An independent claim is included for a device for combined determination of a current roll angle of a motor vehicle and a current road transverse slope of a curved road section driven by the motor vehicle.
