摘　　要：汽车电动转向器和电子稳定控制器既需要测转向转矩又需要测转向角度,研究了一种安装于汽车转向柱的非接触式磁阻转矩/转向角集成转向传感器,通过对信号变换方法的创新研究和信号变换装置的设计,将转矩/转角2种传感器集成为一个传感器,实现对转矩/转角的同时测量。通过仿真研究表明传感器结构、信号变换方法和信号调理电路的性能可以满足设计要求。Steering torsion and steering angle are needed for vehicle EPS （Electric Power Steering） and ESP （Electronic Stability Program）. A new type of magneto-resistance integrated steering torsion/steering angle sensor which can be assembled on the vehicle steering column is presented in this paper. This sensor can measure the steering torsion/steering angle at the sarne time through signal alternation method research and signal alternation device design. It is showed by simulating that the sensor structure and signal alternation mechanism as well as the characteristic of the signal process circuit can meet the design requirements.
