The invention discloses a steering wheel turning angle automatic correction method, which comprises the following steps: after an automatic correction function customer configuration switch is turned on, executing a steering wheel turning angle long-time correction algorithm and a steering wheel turning angle short-time correction algorithm; calculating a corrected steering wheel rotation angle and a corrected dynamic steering wheel rotation angle according to the calculated long-time correction value and the calculated short-time correction value; the steering wheel angle long-time correction algorithm is used for correcting permanent steering wheel angle zero deviation, and the steering wheel angle short-time correction algorithm is used for correcting temporary steering wheel angle zero deviation. According to the method, it can be ensured that the zero position of the steering wheel turning angle is dynamically kept consistent with the straight running state of the vehicle, and the phenomenon that the vehicle deviates or the left-right symmetry of the steering performance is inconsistent due to unexpected power output caused by functions related to the steering wheel turning angle is avoided.
本发明公开了一种方向盘转角自动校正方法,当自动校正功能客户配置开关打开后,执行方向盘转角长时校正算法和方向盘转角短时校正算法;并根据计算得到的长时校正值和短时校正值计算校正后的方向盘转角和校正后的动态方向盘转角;所述方向盘转角长时校正算法用于校正永久性的方向盘转角零位偏差,所述方向盘转角短时校正算法用于校正临时性的方向盘转角零位偏差。本发明可以确保方向盘转角的零位与车辆的直行状态动态地保持一致,避免与方向盘转角相关的功能导致的非预期的助力输出,进而导致车辆出现跑偏或者转向性能左右对称性不一致等现象。
