The embodiment of the invention provides a steering neutral position correction method and system and a vehicle, and the method comprises the steps: determining a first correction value smaller than a neutral position offset according to the to-be-corrected neutral position offset; correcting the steering neutral position by adopting the first correction value, and judging whether the corrected steering neutral position meets an expected correction condition or not; if yes, a second correction value smaller than the median offset continues to be determined, and the steering median continues to be corrected through the second correction value till the corrected steering median meets the correction stopping condition. Due to the fact that the correction value smaller than the neutral position offset is adopted to correct the steering neutral position every time, and then next correction is conducted after it is determined that the corrected steering neutral position meets the expected correction condition, it can be guaranteed that the steering capacity of the vehicle can be improved every time through correction, and the steering capacity of the vehicle can be improved through a stepped increment correction mode. The sudden change of the steering characteristic of the steering neutral position correction vehicle can be weakened, so that the driving safety of the vehicle can be improved.

    本申请实施例提供了一种转向中位修正方法、系统及车辆,该方法中,根据待修正的中位偏移量,确定小于该中位偏移量的第一修正值;采用第一修正值对转向中位进行修正,判断修改后的转向中位是否满足期望修正条件;若是,则继续确定小于该中位偏移量的第二修正值,并继续采用第二修正值对转向中位进行修正,直到修正后的转向中位满足修正停止条件。由于每次采用小于中位偏移量的修正值对转向中位进行修正,然后在确定修正后的转向中位满足期望修正条件后再次进行下次修正,可以保证每次修正都可以改善车辆的转向能力,并且通过阶梯式增量修正的方式,可以削弱转向中位修正车辆的转向特性的突变,因此可以提高车辆行驶的安全性。
