摘要: 为提高混合动力电动汽车的驾驶性能,将冲击度作为评价指标研究车辆的驾驶性能。通过试验研究找到提高整车控制品质、改善混合动力电动汽车驾驶性能的方法。以含有机械式自动变速器的某型混合动力轿车为研究对象,通过对车辆在整个行驶过程中产生冲击度的机理进行分析,设计出相应的试验方案,对车辆在起步、驱动状态切换、换挡以及制动等典型过程中的冲击度进行试验研究。试验结果表明,优化离合器分合速度,协调控制发动机和电动机的转速、转矩可以有效减小车辆冲击度。

Abstract: In order to improve the driveability of hybrid electric vehicles (HEVs), the degree of jerk is selected as the evaluation parameter to evaluate the driveability of HEVs. With the analysis of experiment results, some methods are brought out to improve control quality and driveablity of HEVs. The reason of jerk is studied, experiment plan is worked out. Experiments of starting, state-changing, shifting and braking are implemented and well analyzed. The whole work is done on a hybrid electric car by using an automated mechanical transmission. Experimental results indicate that the degree of jerk can be reduced by optimizing the clutch control and by coordinately controlling the engine and motor’s speed and torque.
