Abstract :
Torque sensor is an important component of EPS system. The output characteristics of the sensor determine the performances of EPS system. This paper provides a design of torque senor for EPS system, using inductive electric bridge with sine-wave motivation. We designed a sine-wave driving source with properly stable frequency and amplitude, an intelligent adjusting circuit for the electric bridge based on digital potentiometer. We also designed detailed signal collection and processing circuit. The test showed that the designed circuits are suitable for the application to EPS system with the feature of high stability and good linearity of output.
