汽车前轮转向角测试误差修正算法研究

Algorithm for correcting turning-angle test error of vehicle's front-wheel

提出一种利用汽车转向桥机械结构特性解决汽车转向轮转向角测试误差修正的算法,通过该算法可计算出汽车轮胎准确的零转角起点位置,进而对转角测试数据进行修正,以此计算出准确的左右轮最大转向角及相关角,解决了目前汽车转向轮转向角测试数据准确度低、重复性差的问题。

An algorithm to correct turning-angle test error for vehicle steering-wheel was described in this paper,it used the mechanical structure properties of vehicle steering-axle.By this algorithm,the zero turning-angle starting position of the steering-wheel can be accurately calculated,and then the turning-angle test data can be corrected.Furthermore,the accurate maximum turning angles and related angles of the left and the right steering-wheels can be calculated.It solves the problem that the turning-angle test data for the steering-wheel has low accuracy and poor repeatability.
