The invention is suitable for the technical field of electric vehicle control, and provides a wet and slippery road surface torque control method and device and terminal equipment. The method comprises the steps that when it is detected that an anti-lock braking system of a vehicle is activated, according to a comparison result of a torque value corresponding to a current torque request and a preset wheel end torque limiting value, the torque limiting value of a wheel end is determined; the preset torque lower limit value is set as the wheel end torque limit value, the situation that the wheels are locked again due to sliding energy recovery is prevented, after the vehicle keeps the wheel end torque limit value for a first preset time, when a new wheel end torque value corresponding to the new torque request is larger than the first torque value, limitation of the vehicle sliding energy recovery capacity is relieved, and the preset torque lower limit value is modified into the wheel end default torque value,
