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.
