It is significant to consider human factors for the design of the intelligent safety vehicle beyond the general vehicle's performance. Therefore, the development of an ergonomic driver model to imitate the human driving pattern is essential for the advanced vehicle research considering the human factors. In this paper, several tests for the study of the human factors are conducted, and the control logic to describe the human driving pattern is presented. First of all, human factors to influence a vehicle operation are assumed to be consisted of two major components, the preview distance and the human neuromuscular response. Secondly, the control logic is consisted of the finite preview optimal control algorithm to account for human factors mentioned previously. Finally, the ergonomic driver model is developed based on these and simulated with Carsim software in SIMULINK environment.
