The invention relates to a steering neutral position correction method and device, electronic equipment and a storage medium, and is applied to the technical field of vehicles. The method comprises the steps that the position of a lower steering motor rotor is detected in real time; if the absolute value of the position of the motor rotor is larger than the angle threshold value, the offset between the current middle position of the downward steering rack and the original middle position is calculated, and 1 is added to the statistical value; wherein the initial value of the statistical value is 0; under the condition that the statistical value reaches a preset number, determining a first target offset according to a preset number of offsets; and updating the middle position of the rack to the sum of the original middle position and the first target offset. After the vehicle is used for a long time, the control accuracy of the steer-by-wire can be improved.

    本申请涉及一种转向中位修正方法、装置、电子设备及存储介质,应用于车辆技术领域,所述方法包括:实时检测下转向电机转子的位置;如果电机转子的位置的绝对值大于角度阈值,计算下转向的齿条的当前中间位置距离原始中间位置的偏移量,并将统计值加1;其中,统计值的初始值为0;在统计值达到预设数量的情况下,根据预设数量个偏移量,确定第一目标偏移量;将齿条的中间位置更新为原始中间位置与第一目标偏移量之和。本申请可以在车辆长期使用后,提高对线控转向的控制精准度。
