The position design of in-vehicle information display was analyzed in order to improve the safety of in-vehicle information display design. Five common positions of in-vehicle information display equipment were selected. The eye movement experiment was designed to simulate the task of information reading during driving by considering the relationship between driver's visual behavior and driving safety. The analysis and comparison of experimental data show that different in-vehicle information display positions will have a significant impact on the fixation frequency when the driver reads the information and the distribution of fixation data in the area of interest (AOI). The mean values of the fixation frequency, the percentage of fixation time in AOI and the percentage of fixations in AOI were analyzed and compared. The data of position 3 were highest in the 5 display positions selected in the experiment. Results showed that the participants were more focused on reading the information in position 3, and the visual deviation effect of the participants in position 3 was the least. Driver's visual deviation will cause distracted driving and threaten driving safety. The position design of in-vehicle information display will have a certain impact on driving safety.
