Abstract:
In order to evaluate road alignment, the driver direction control model was established based on trajectory-preview theory and real time vehicle state, and the vehicle turning characteristics and operating lag was considered. The computer program was developed with VB 6.0, and simulation experiment was conducted. The result indicated that the model can calculate lateral acceleration and steering wheel angle of test vehicle during driving, the indices reflects safety and driver comfort of the road and can be employed in road alignment evaluation. Remarkable difference of running results between initial speed of 0 and 54 km/h appears only at the start of the road section. During steady running of the experiment, the variation of lateral acceleration and turning angle of steering wheel are in basically accordance with horizontal curve. 2 tabs, 5 figs, 12 refs.
