The paper presents an approach to reliably detect and treat sensor faults in drive systems. For detecting errors in current and rotor position sensors, model-based methods (sensorless position estimation, current observers) are used. Sensor faults in the drive system may cause erroneous or oscillating torques. In vehicles with wheel hub drives on the rear axle and without additional driving safety systems, such faults could even result in driving conditions that are difficult to control. The error detection system is verified by measurements on a test bench. Vehicle tests on a test track prove the effectiveness of the procedures for in-vehicle use.
