This invention provides a method for calculating the torque of a distributed loading vehicle and the distributed loading vehicle itself. The calculation method includes: obtaining the actual required torque based on the driving state, the battery's limited power, and the motor's rotational speed; distributing the actual required torque evenly to the front and rear axles, and further distributing the torque of the front axle to the two motors on the front axle and the torque of the rear axle to the two motors on the rear axle based on the steering angle, thus obtaining the required torque for all four motors; obtaining the axle slip ratio and axle acceleration, and if at least one of the following conditions is met: the slip ratio is greater than a preset slip ratio threshold, and the axle acceleration exceeds a preset acceleration threshold, then the required torque for the two motors corresponding to the abnormal axle is transferred, wherein the abnormal axle is the axle that meets the conditions. Therefore, it is possible to actively intervene in the torque of the abnormal axle after detecting slippage or lock-up, thereby improving vehicle safety, ensuring vehicle power performance, and reducing wheel wear.
