方向盘转角传感器研究进展

方向盘转角传感器是汽车动力学稳定性控制(electronic stability program,ESP)系统的重要组成部分,其精度和稳定性直接关系着行车安全。传统的方向盘转角传感器基于多种原理,如,光电效应、霍尔效应、磁阻效应、电阻分压效应等。根据原始信号编/解码方式的不同,转角传感器可以分为绝对值转角传感器和相对值转角传感器。目前,又出现了一些新型的方向盘转角传感器,如,AMR,GMR方向盘转角传感器等,介绍了这些新型传感器的一些性能参数。

Research development of steering wheel angle sensor

Steering wheel angle sensor is an important part of the electronic stability program(ESP)system,its accuracy and durability concern the safety of driver.Conventional angle sensors base on several principles,such as photoelectricity,Hall,magnetoresistive and potential dividing effects.According to the encoding/decoding methods of the original signal,the sensors can be divided into absolute and relative steering sensors.At present there are some new-designed sensors,such as AMR,GMR steering wheel sensor.The parameters of these sensors are given.
