The invention relates to a torque adjusting method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that state information of a traction control system (TCS) of a vehicle, a target rotating speed difference between two wheels connected with a differential mechanism of the vehicle and target wheel end torques of the two wheels are obtained; determining a target wheel end torque subinterval where the target wheel end torque is located in a target interval corresponding to the target rotating speed difference; under the condition that the state information and the target wheel end torque subinterval meet preset conditions, the product of the target wheel end torque and the target torque reduction coefficient is determined as first torque; the target torque reduction coefficient corresponds to the target wheel end torque subinterval, and the value range of the target torque reduction coefficient is [0, 1]; torque of a drive motor of the vehicle is adjusted based on the first torque. Therefore, the differential mechanism can be protected, meanwhile, the stability and flexibility of vehicle control are improved, and the user experience is improved.
