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.
