The invention relates to an electric vehicle driving torque distribution method and device, computer equipment and a storage medium. A constraint range of a torque distribution coefficient is obtained; the constraint range of the torque distribution coefficient is divided into a plurality of sub-constraint ranges; in each sub-constraint range, according to the torque distribution coefficient and apreset iterative algorithm, an optimization objective function is solved to obtain a target torque distribution coefficient enabling the output value of the optimization objective function to be minimum, thereby obtaining a torque distribution coefficient enabling the stability and economy of the electric vehicle to be optimal; and the torque required by a front motor and the torque required by arear motor of the electric vehicle are obtained according to the target torque distribution coefficient and the total required torque. According to the method, the range of the torque distribution coefficient can be constrained, the calculation amount is reduced, the torque distribution mode is prevented from being too extreme, the optimal torque distribution coefficient can be calculated in eachsub-constraint range, the calculation time is shortened, and an effect of torque distribution enabling the economy and stability to be optimal is achieved.
Description
technical field [0001] The present invention relates to the technical field of automobiles, in particular to a driving torque distribution method, device, computer equipment and computer-readable storage medium of an electric vehicle. Background technique [0002] With the continuous deterioration of the environment and the rapid shortage of energy, various products using clean energy are developing at a growing rate, and countries around the world are also subsidizing these products, among which electric vehicles are products using clean energy As a new energy vehicle, electric vehicles have the advantages of no pollution, low noise, high energy efficiency, diversified energy sources, and convenient maintenance. Among them, the electric vehicle driven by dual motors is one of them. The electric vehicle driven by dual motors can improve the working efficiency of the whole vehicle, thereby increasing the cruising range. [0003] Electric vehicles driven by dual motors usuall...
