摘　　要：在发动机动态试验台上实现了对车辆、道路载荷、驾驶员操纵特性及整车行驶工况的动态模拟,并在国内首次利用发动机动态试验台对驾驶员纵向操纵特性对动力系统性能的影响进行了研究。具体包括动力性和经济性两类换挡规律对汽车加速性能和基于EUDC工况的百公里油耗的影响,以及换挡动作快和换挡动作慢两类驾驶员对汽车起步和换挡过程品质影响的研究。通过发动机动态试验台的试验,得出了驾驶员的纵向操纵特性对汽车动力性、燃油经济性和换挡品质的影响的规律,提高了我国对发动机动态试验台的应用水平。Engine dynamic test bed can simulate vehicle, road load, driver behaviors and drive cycles. Firstly in China, the study on the impact of driver behavior upon vehicle's acceleration, fuel consumption, starting and gear shifting quality is carried out on engine dynamic test bed. Two typical gear shifting model named dynamic shifting and economic shifting and two classical driver model called fast driver and slow driver are made. The experiment proves that different gear shifting models result in different acceleration and fuel consumption performance based on EUDC cycle. The calculations also clarify the two type drivers' influence on vehicle starting and shifting quality.
