As the level of automation of autonomous vehicles continues to increase, it is becoming more and more important to study the behavior characteristics of drivers to optimize the behavioral characteristics of autonomous vehicles. In order to study the characteristics of driver overtaking behavior, this study convened 5 testers to carry out a 2×3 in-test design experiment based on a six degrees-of-freedom (DoF) driving simulator. The time-to-collision (TTC), the longitudinal distance between two vehicles, and the steering wheel angle at the begin time of the overtaking behavior are taken as the analysis indicators to characterize the behavior characteristics of the driver. The result shows that the different speeds of the vehicle have no statistically significant effects on the behavior characteristics of the driver (TTC, $\mathbf{P}{=0.187 > 0.05;}$ Longitudinal distance, $\mathbf{P}{=0.682 > 0.05;}$ Steering Angle, $\mathbf{P}{=0.052 > 0.05).}$ The speed difference will significantly affect the values of the above three indicators. A larger speed difference will result in a smaller TTC and a larger distance between the two vehicles and the steering wheel angle. This paper can provide theoretical support for designing driving strategies with more human behavior characteristics.
