Abstract: A novel single-point preview driver model is established in this paper, and the effects of preview time and error feedback coefficient on tracking performance are analyzed. An assumption is put forward that the radical cause of the steady-state error is “there is a coupling between longitudinal preview time and lateral acceleration time”. By setting a time coefficient F, characterizing the relationship between lateral acceleration time and longitudinal preview time, this model can track a given curved road without error, while ensuring the vibration frequency of the system adjustable
