The concept of DODF and other two evaluation indices based on DODF were proposed. Based on the optimal preview acceleration driver model, the effect of driver model parameters on the performance of driver-vehicle-road closed-loop system was studied by the closed-loop system simulation. The results show that the preview time of a driver who has good driving habits should be always larger than a certain valueTP0, the increase of both nerve delay timetdand muscle lag timeThlead to the increase ofTP0, andtdhas more effect onTP0thanThdoes. The increase of bothtdandThlead to the decrease of DODF, andtdhas more effect on DODF thanThdoes. Furthermore, the increase of bothtdandThalso lead to the increase of both tracking indexJEMand driving load indexTCM,tdhas more effect onJEMthanThdoes, andThhas more effect onTCMthantddoes.
