Abstract: 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.
Key words: Engine dynamic test bed Driver longitudinal operating
