Research on Speed Ratio Optimization Design of Wheel Side Motor Driven Electric Vehicle

针对轮边电机驱动型汽车进行系统仿真,分析了以高速车速区间和电机高速区间重合为前提的电机和电池参数的匹配方法,并对电子差速控制进行优化设计。通过分析表明,以加权工况平均耗能为目标的优化速比耗能最优,具有较好的适用性。

Based on the system simulation of the wheel-side motor-driven vehicle,the matching method of the motor and the battery parameters on the premise of the high-speed vehicle speed section and the high-speed section of the motor is analyzed,and the electronic differential control is optimized.The analysis shows that the average energy consumption of the weighted working condition is the optimal ratio of the optimized speed ratio of the target,and has good applicability.
