“…Combined with the power system structure of the axle motor directly driving the wheel, the torque of the shaft motor and the torque required by the power system can be further decoupled. According to the boundary conditions and optimization objectives formulated by Equations (20) and (21), the ratio K of the output torque of the motor of the two shafts before and after can be calculated according to the DP algorithm, and then the distribution of output torque of the two shafts can be conducted. Figure 9 is the result obtained according to DP global optimization algorithm.…”

All-wheel drive is an important technical direction for the future development of pure electric vehicles. The difference in the efficiency distribution of the shaft motor caused by the optimal load matching and motor manufacturing process, the traditional torque average distribution strategy is not applicable to the torque distribution of the all-wheel drive power system. Aiming at the above problems, this paper takes the energy efficiency of power system as the optimization goal, proposes a dynamic allocation method to realize the torque distribution of electric vehicle all-wheel drive power system, and analyzes and verifies the adaptability of this optimization algorithm in different urban passenger vehicle working cycles. The simulation results show that, compared with the torque average distribution method, the proposed method can effectively solve the problem that the difference of the efficiency distribution of the two shaft motors in the power system affects the energy consumption of the power system. The energy consumption rate of the proposed method is reduced by 5.96% and 5.69%, respectively, compared with the average distribution method under the China urban passenger driving cycle and the Harbin urban passenger driving cycle.
