Design and optimization of the sensor gear set in EPS

摘要

This paper aims at improving the design of torque sensor used in the EPS system. Such design not only integrates the torque and the corner signal, but also saves space. By using Matlab interior point method, the gear system parameters are optimized and the weight and the size of the sensor are reduced. Bench test results demonstrate that the measurement accuracy of this self-designed sensor is able to meet the demands of EPS.
