ABSTRACT:
A method is for determining a geometric vehicle inclination α of a motor vehicle, where an acceleration signal of at least one acceleration sensor is used and a speed gradient dv/dt is determined from a measured vehicle speed v, where a) in the case of a moving or standing vehicle, an acceleration value aSis derived from a force acting on the acceleration sensor, b) a corrected acceleration value akorris determined as a function of the speed gradient dv/dt, and c) the current vehicle inclination α is directly deduced from the corrected acceleration value akorr. In addition, a device for implementing a method to determine a geometric vehicle inclination α of a motor vehicle, the device includes a speed-measuring device and at least one acceleration sensor, a programmable and readable microcontroller being provided, with the aid of which the current vehicle inclination a may be calculated from the values of the speed-measuring device and the acceleration sensor at a vehicle speed v of the vehicle greater than or equal to zero, and directly transmitted to at least one control unit.
