装备机械自动变速器(AMT)的混合动力车辆驱动系统包含了发动机、电机和电池以及传动系统,不能按照传统AMT车辆的方法制定其换挡规律。在综合考虑发动机、电机的工作性能以及电池荷电状态的基础上,以燃油经济性能为目标,提出了装备机械自动变速器的轻度混合动力车辆电动机部分助力时的能量分配策略和经济性换挡规律,并进行了仿真。结果表明,采用新的经济性换挡规律,能更加有效地发挥混合动力车辆的性能,提高燃油经济性。
The hybrid vehicle drive system equipped with mechanical automatic transmission (AMT) includes the engine, the motor and the battery, and the transmission system, and can not formulate the shift pattern according to the conventional AMT vehicle. Based on the consideration of the working performance of the engine and the motor and the state of charge of the battery, aiming at the fuel economy performance, an energy allocation strategy and economic shift of the hybrid hybrid vehicle with partially assisted mechanical transmission are proposed Law, and conducted a simulation. The results show that using the new economic shift schedule, the performance of hybrid vehicles can be more effectively utilized and the fuel economy can be improved.
