The invention belongs to the technical field of automobile steering systems, and relates to a method for correcting a steering wheel angle and a wheel angle of steer-by-wire, which comprises the following steps of: detecting and judging a steering wheel and wheels by a force sense-execution motor system after an automobile is ignited and before the automobile is started; by means of the method, the physical locking function of a steering wheel and the physical locking function of a steering system can be reduced, the middle position of the system can be corrected again in each ignition period, the corresponding system can be corrected, meanwhile, the good power-on correction function is achieved for errors generated in the dormancy process, errors caused by the influence of external force on the system, errors caused by human initiative and the like, and the reliability of the system is improved. And the safety coefficient and the function safety capability of the system are greatly improved.

    本发明属于汽车转向系统技术领域,涉及一种线控转向方向盘角度与车轮角度校对的方法,通过在车辆点火后启动前将方向盘及车轮经力感‑执行电机系统检测判定后回正的方式;使得本发明可减少方向盘物理锁止和转向系统物理锁止功能,每个点火周期都会重新校对系统中位及相应系统校对,同时对于休眠时产生的误差、系统受外力影响而带来的误差和人为主动造成的误差等,起到很好的上电修正功能,极大提高了系统安全系数及功能安全能力。
