直线行驶过程中汽车方向盘转角的研究分析

介绍了一种汽车方向盘转角传感器，搭建了汽车方向盘转角数据采集系统。依据在北京五环路上的行驶实验，分析了驾驶前期和后期方向盘转角特性的不同，得出驾驶员正常驾驶汽车直线行驶时方向盘转角范围约在其回正位置的左右7°之间，方向盘紧定时间在9s内。实验结果为驾驶行为研究、驾驶疲劳监测及相关产品的开发提供了参考。

The research on automobile steering wheel angle in the cause of straight driving

A steering wheel angle sensor was introduced and a data acquisition system for steering wheel angle was built. The driving experiment at Beijing 5th Ring Road was realized to analyze the difference of steering wheel angle characteristics between the earlier and the later driving stage. When the driver drives straight in natural state, the range of steering wheel angle is from -7° to 7° based on the central position and the fixed steering wheel time is less than 9 seconda The experimental results provide important references for driving behavior research, driver drowsiness detection and the development of related products.
