摘要
在建立混合动力电动汽车(HEV)动力驱动模型的基础上,运用Matlab/Simulink软件,建立汽车闭环控制系统仿真模型并进行动态计算机仿真。通过对设定不同车速及控制器参数,汽车实际车速响应情况以及响应与系统输入力矩之间关系的分析,发现现有HEV控制策略难以在实现环保与节能目标的同时,保证汽车动态性能的问题,提出面向动态过程的HEV多能源动力总成系统控制方法,并论述了其原理及实现方法。
On the base of building a HEV propulsion model,the simulation synthesis for a closed -loop control system of a given HEV is built, By analysing the virtual velocity output and the desired input torque on the time domain of the HEV at different target velocitys and controller parameters ,we has found that it is difficult to achieve both the objects of consumption minimization and dynamic function optimization using the conventional control strategies for HEV, In this paper,a control method for the HEV propulsion system based on the dynamic process is proposed, and its principle and implement are discussed,
