Abstract：This article systematically introduces the classification and working principle of torque sensors used in electric power steering systems， and at the same time expounds the key performance indicators and the general requirements of each indicator. And from the perspective of sensor matching and the relationship between output voltage and torsion bar， the matching of the sensor and EPS system is discussed， which has guiding significance for the development of subsequent torque sensors.

Key words：torque sensor， working principle， performance index
