The invention relates to the technical field of automobiles, and provides a steering wheel rotation angle measuring method, a controller, a vehicle and a readable storage medium, and the measuring method comprises the steps: obtaining a first angle signal collected by a rotation angle sensor; obtaining a first absolute angle according to the first angle signal and a vernier algorithm; performing angle following on the first angle signal to obtain an increment angle, and obtaining a following angle according to the first absolute angle and the increment angle; and according to the following angle, obtaining an actually measured rotation angle of the steering wheel. Therefore, when the original signal jumps at the same moment or at different moments, the actually-measured turning angle of the steering wheel does not jump, and the accuracy of the actually-measured turning angle of the steering wheel is improved.
本公开涉及汽车技术领域,提供一种方向盘转角测量方法、控制器、车辆及可读存储介质,该测量方法包括:获取转角传感器采集的第一角度信号;根据第一角度信号和游标算法,得到第一绝对角度;对第一角度信号进行角度跟随,得到增量角度,并根据第一绝对角度和增量角度,得到跟随角度;根据跟随角度,得到方向盘的实测转角。这样,使得在原始信号发生同时刻或者不同时刻跳变时,方向盘的实测转角不跳变,提升了方向盘实测转角的准确度。
