摘要：
A regenerative braking strategy was designed for a distributed drive vehicle with a centralized motor drive on the front axle and a hub motor on the rear axle, namely Strategy 1. According to the power transmission process in a braking, the concept of the total efficiency of the power generation system was proposed, and the optimal front and rear motor force distribution coefficient was obtained based on its maximum of it. Then, under the constraints of ECE(Economic Commission of Europe) regulations, the regenerative braking economic optimization strategy was designed, namely Strategy 2. For vehicles equipped with ABS(Antilock Brake System), when the braking strength is small (z<0.2), the rear axle motor can be preferentially used in regenerative braking. Therefore, an economic optimization strategy at low braking strengths was proposed, namely Strategy 3, to make the most of the efficient area of the power generation system. The analysis demonstrates that the proposed strategy has little effect on braking feel. The simulation results show that the energy consumption of the three strategies is reduced by 14.05%, 15.04% and 16.64%, respectively. © 2020, Editorial Department of Journal of Tongji University.
