并联式混合动力客车AMT换挡过程分析及其验证

摘要

The article puts forward AMT shift control method for HEV and according to the speed - time information of the city bus, and the urban road conditions, optimizes the control parameters for each bus. The parameters are automatical y acquired in the run-ning process to judge the road conditions. The vehicle control er is used to take the optimal control parameters and energy distribution pattern to optimize the adjustment of the torque output and energy recovery of the vehicle motor and engine.The energy is rational y assigned to the vehicle. It not only meets the needs for the vehicle's power, but also the fuel consumption and pol utant emissions are effectively reduced and the fuel economy is improved.%提出了一种混合动力汽车的AMT挡位控制方法，根据城市公交客车的车速-时间历史统计信息制定一组道路工况，针对每一种道路工况制定相应的优化控制参数；在车辆行驶过程中自动采集行驶参数判断对应的道路工况，并由整车控制器采取相应的优化控制参数及能量分配模式，优化调整车辆电机和发动机的扭矩输出及能量回收。对客车能源进行合理分配，不仅满足了整车的动力性，还有效减少了燃油的消耗和污染物的排放，提高了燃油经济性。
