The invention discloses a traction force control method and device and a storage medium, and the method comprises the steps: determining the error of the slip rate of a vehicle, and correcting the optimal slip rate based on the error to serve as a target slip rate; the deviation between the current slip rate and the target slip rate of the wheel is determined, and the variable quantity of the wheel cylinder pressure is calculated based on the deviation; a brake pressure adjusting strategy of the vehicle is determined according to the variable quantity of the wheel cylinder pressure, and the brake pressure output to wheels is controlled based on the adjusting strategy; the current slip rate of the wheels is recalculated and compared with the target slip rate, if the slip rate does not reach the standard, output control over the brake pressure continues, or the target slip rate is updated, the brake pressure adjusting strategy is determined again, and the brake pressure output to the wheels is adjusted based on the adjusting strategy. TCS is achieved through pressure increasing, pressure maintaining and pressure reducing in all periods, and the driving performance and safety of the vehicle are guaranteed.
