【摘要】 转矩传感器是汽车电动助力转向系统(EPS系统)的关键部件之一,其输出特性直接影响到EPS系统的控制性能。在分析国外EPS系统转矩传感器的基础上,根据EPS系统的要求,设计开发了一种结构简单、成本低廉的光电式非接触转向盘转矩传感器。给出该光电式传感器的结构和原理,并对其进行测试;对传感器输出特性的分析表明:所设计的光电式转矩传感器在输出重复性、温度漂移等综合性能方面基本满足EPS系统的要求。更多还原

【Abstract】 The torque sensor is one of the key parts of an electric power steering system(EPS system),and the characteristic of EPS system is much concerned with the output of the torque sensor.Based on analysis of the overseas the torque sensors used in EPS system,a new optical torque sensor with simple structure and low cost has been designed.The principal and structure of the torque sensor were proposed,and its output characteristic was analyed.It has been found that the torque sensor meets the requirement of EPS system in output repetition,temperature excursion,etc.更多还原
