Angle adjusting and monitoring unit for use in motor vehicle, sets actual angle on basis of desired angle and has actual angle sensor for determining actual angle of adjusting unit

摘要

The monitoring system is designed so that monitoring facilities (10,11) are provided, which based on a dynamic model, a forecast of the actual angle (DELTA V) is carried out, from the knowledge of the desired angle (DELTA M + DELTA R) and from the travel dynamic variables. The forecast actual value is compared with the sensor determined actual value (15). A fault signal (17) is then derived from the comparison result, using a fault identification algorithm.
