Abstract

Abstract:

In order to investigate the differences in pre-crash behavior of car drivers and the effects on vehicle active collision avoidance of electric two-wheelers accidents. By building 3 typical scenarios of electric two-wheeler accidents and 3 driving speed scenarios in a six-degree-of-freedom driving simulator to conduct volunteer tests, the differences in drivers’ emergency collision avoidance behaviors in different accident scenarios and their effects on accident occurrence were investigated by combining nonparametric tests and binary logistic regression analysis methods. The results showed that the driver’s pre-crash characteristics of braking reaction time, perception time, movement time, average brake pedal opening and average accelerator pedal opening were significantly different in different typical scenarios, and the driver’s reaction characteristics were significantly different in different driving speeds only in the case of large speed differences. Among them, brake reaction time, average brake pedal opening and average steering wheel angle are important factors affecting the occurrence of collision. The results of the study provide theoretical references to improve the safety design of the vehicle automatic emergency braking system for collision avoidance electric two-wheelers.

Key words: active collision avoidance, driver behavior, two-wheeler accidents, six-degree-of-freedom driving simulation, non-parametric tests, binary logistic regression
