Abstract

This paper deals with the evaluation of rotor shaft position sensor systems used in automotive electric powertrain applications. Those sensor systems comprise of an angular rotor position sensor as well as the powertrain's electronic control unit (ECU), processing the sensor data in terms of digitalization, filtering, position- and speed computation. The work introduces an evaluation method of influencing factors on the accuracy of rotor position measurement, e.g. quantization errors, filter settings and time latency of data processing chain. In this way, performance evaluation and investigation of electric powertrain sensor systems is enabled by combination of specific simulation and measurement procedures.
