The invention relates to a traction control system control method and device, a controller and a medium. The method comprises the steps that in the starting process of a target vehicle, the wheel speed, the wheel tire pressure, the vehicle deceleration and the torque output of the target vehicle in the current control period are obtained; according to the tire pressure, the vehicle deceleration and the road adhesion coefficient, an oscillation fundamental frequency is obtained, and a wheel phase frequency spectrum signal is obtained based on the wheel speed; according to the oscillation fundamental frequency and the wheel phase frequency spectrum signal, harmonic frequencies and harmonic energy of the multiple harmonic waves are obtained, and a harmonic energy proportion is obtained; under the condition that the harmonic energy proportion or the vehicle speed of the target vehicle in the current control period meets a preset condition, a torque output control gain coefficient is obtained according to the harmonic energy proportion, the vehicle speed and the target harmonic frequency; and generating a torque output control instruction based on the torque output control gain coefficient and the torque output data. By adopting the method, the suppression effect of the vibration divergence phenomenon can be improved.
