Design of Optimized Energy Management Strategy for All-Wheel-Drive Electric Vehicles

The performance of the all-wheel-drive electric vehicle is inseparable from energy management strategy (EMS). An outstanding EMS could extend cycling mileage, coordinating power output battery and exerts advantage motor comprehensively. However, current has poor in real-time, this paper proposes dynamic programming coordination (DPCS) to solve problem. Firstly, based on a rule-based control (RBCS) applied different driving cycle. Secondly, algorithm (DP) proposed process. DPCS cooperated RBCS DP, extracting boundary parameters along with demand speed. Finally, number motors joined condition elucidated method obtains optimal torque split ratio through partly-known By incorporating thought basis rules, determines each that confirm working an efficient range incorporates mind programming. validated simulation. results show can significantly improve mileage cycle, comprehensive distribution utilization.
