摘要
双电机驱动是提高电动车辆整车性能的有效方法,本文提出一种双电机耦合驱动系统的新构型;基于这种构型的特点,定义了双电机的4种驱动模式;依据车辆动力性要求计算出驱动系统各参数取值范围。根据双电机驱动系统的结构原理,提出基于门限值的模式切换控制策略;在Matlab/Simulink中搭建控制策略仿真模型,并与Cruise中整车模型进行联合仿真。仿真结果表明,这种新构型和控制策略在满足车辆动力性的前提下,可有效提高车辆的经济性。
Dual-motor drive is an effective method to improve the performance of electric vehicles.A new configuration of dual-motor coupling drive system is proposed;based on the characteristics of this configuration,four dual-motor drive modes are defined;according to the requirements of vehicle dynamics Calculate the value range of each parameter of the drive system.According to the structural principle of the dual-motor drive system,a threshold-based mode switching control strategy is proposed;a control strategy simulation model is built in Matlab/Simulink and co-simulated with the entire vehicle model in Cruise.The simulation results show that this new configuration and control strategy can effectively improve the economy of the vehicle under the premise of satisfying the dynamics of the vehicle.
