The invention discloses a steering angle limit position calibration method, a steering controller and an automobile, and relates to the field of automobile chassis electric control. The method comprises the following steps that: when a steering limit angle learning condition is met and a learning instruction is received, a steering angle limit learning flag bit is set as unlearned, and original left and right steering angle limit values are cleared; a steering engine is controlled to respectively steer to left and right limit positions, and maintain for preset time; a left limit angle and a right limit angle of a steering angle are respectively obtained; and when the angle difference value between the left limit angle and the right limit angle is within a preset range, the left limit angleand the right limit angle are stored, and learning of the steering limit angle is completed. Steering limit angle learning can be performed under the condition of meeting steering limit angle learning conditions so that the left limit angle and the right limit angle of the steering angle can be updated, and the situation that a driving assistance system and an electric control system in the fieldof a chassis cannot be accurately controlled due to the fact that the current left limit angle and the current right limit angle are inaccurate can be avoided.

    本发明公开了一种转向角极限位置的标定方法、转向控制器及汽车,涉及汽车底盘电控领域。其方法包括:当满足转向极限角度学习条件,且接收到学习指令之后,将转向角度极限学习标志位设为未学习,清除原有的左右转向角度极限值;控制转向机分别转向至左右极限位置,并保持预设时间;分别获取转向角的左极限角度和右极限角度;当左极限角度和右极限角度的角度差值在预设范围之内时,存储左极限角度和右极限角度,转向极限角度学习完成。本发明在满足转向极限角度学习条件下能够进行转向极限角度学习,以便对转向角的左极限角度和右极限角度进行更新,避免由于当前的左右极限角度不准确导致无法精确控制驾驶辅助系统和底盘领域的电控系统。
