The invention relates to a steering wheel angle null drift test method, a test system, a test device and a computer readable storage medium. The steering wheel angle null drift test method comprises the following steps: S1, setting a target steering wheel turning angle of a vehicle to be 0 degree; s2, the vehicle runs for the duration b according to the vehicle speed v, and the course angle theta and the vehicle speed v of the vehicle are recorded; s3, calculating a front wheel deflection angle delta based on the course angle theta, the vehicle speed v and the wheelbase L of the vehicle; s4, calculating a steering wheel turning angle A based on steering wheel steering characteristics and the front wheel deflection angle delta; s5, judging whether the steering angle A of the steering wheel is within-1 degree to + 1 degree or not, if not, turning to step S6, and if yes, turning to step S7; s6, setting the rotating angle of the target steering wheel as-A, and entering the step S2; and S7, determining the steering wheel angle A as the steering wheel zero drift angle. The invention provides a steering wheel angle zero drift test method, a test system, a test device and a computer readable storage medium. The steering wheel angle zero drift angle can be effectively obtained.

    本发明涉及一种方向盘角度零漂测试方法、测试系统、测试设备及计算机可读存储介质。该方向盘角度零漂测试方法包括步骤S1,设置车辆的目标方向盘转角为0°;S2,车辆依照车速v运行时长b,记录车辆的航向角θ和车速v;S3,基于车辆的航向角θ、车速v和轴距L计算前轮偏角δ;S4,基于方向盘转向特性和前轮偏角δ计算得到方向盘转角A;S5,判断方向盘转角A是否在‑1°~+1°以内,若否,转入步骤S6,若是,则进入步骤S7;S6,设置目标方向盘转角为‑A,进入步骤S2;S7,确定方向盘转角A为方向盘零漂角。本发明提出了一种方向盘角度零漂测试方法、测试系统、测试设备及计算机可读存储介质,能有效获得方向盘零位漂移角度。
