The invention relates to the technical field of vehicle steering systems, in particular to a steering precision compensation method for a vehicle steering system, which comprises the following steps: S1, selecting a turning radius, and respectively generating a first function relationship between a left steering wheel and rack displacement and a second function relationship between a right steering wheel and rack displacement according to the turning radius; s2, whether the vehicle steering system meets the precision requirement or not is judged according to the first function relation and the second function relation; if yes, turning to S3; s3, a wheel on one side is selected as a reference point, and the steering deviation corresponding to the turning radius is calculated; and S4, performing precision compensation according to the steering deviation. The method has the beneficial effects that the function relationship between the steering wheel and the rack displacement is constructed under the specific steering radius, so that the steering deviation caused by the design of the steering system is accurately judged, the steering deviation is quantified, the problem that the steering deviation of the vehicle steering system cannot be accurately obtained in the prior art is avoided, and the steering accuracy of the vehicle steering system is improved. And effective compensation of the steering precision of the vehicle steering system is realized.

    本发明涉及车辆转向系统技术领域,具体涉及一种车辆转向系统的转向精度补偿方法,包括:S1:选取一转弯半径,根据转弯半径分别生成左转向轮与齿条位移的第一函数关系,以及右转向轮与齿条位移的第二函数关系;S2:根据第一函数关系和第二函数关系判断车辆转向系统是否满足精度要求;若是,转向S3;S3:选取一侧车轮为参考点,计算对应于转弯半径的转向偏差;S4:根据转向偏差进行精度补偿。有益效果在于:通过在特定转向半径下构建转向轮与齿条位移间的函数关系,从而准确判断出因转向系统设计导致的转向偏差,并对转向偏差进行了量化,避免了现有技术中无法准确获取到车辆转向系统的转向偏差的问题,实现了对车辆转向系统的转向精度的有效补偿。
