Furukawa Review No.25

Development of a Steering Angle and Torque Sensor of Contact-type

Akira Noguchi, Kosuke Yamawaki, Toshiro Yamamoto and Tomoaki Toratani

Abstract

With the growing concern over the global environment in recent years, environmental preservation technologies are required to be developed in the field of automotive industries also. Accordingly, there is an increasing need for electric power steering system (EPS) of low energy consumption to replace hydraulic power steering system conventionally used. Because steering angle and torque sensors used in the EPS are based on contact-type sensing, they tend to have such problems as delayed response caused by the friction of the sensing brush against conductive resin in addition to friction noise. The authors have developed, by studying structures of the rotor and the sliding portions, a low friction noise sensor with outstanding electrical performance.
