Abstract
An inclination sensor system for a mobile work machine includes a MEMS inclination sensor and a further inclination sensor of a different type and a fusion device. The inclination sensor is configured to output a first inclination signal on the basis of an inclination that exists at the inclination sensor. The further inclination sensor is configured to output a second inclination signal on the basis of the inclination that exists at the further inclination sensor. The fusion device is configured to calculate a corrected inclination signal on the basis of the first and second inclination signals and to output same as the corrected inclination signal.
