摘要
制动行为的研究不仅可以应用于交通事故处理中,还可应用于许多汽车安全性能检测设备的设计和标定中。以31个城市1 314辆私家车为数据采集样本,获取道路实测数据,并对数据进行制动行为分析。结果表明:在国内,私家车正常制动行为的初速度普遍在低速范围内,75%以上制动行为的制动距离在90 m以内;制动行为存在区域差异,对比东北地区,长江以南的制动行为的初速度要更加大;与晴天驾驶环境相比,下雪天驾驶员会使用降低制动初速度的保守驾驶来弥补道路附着系数减小带来的制动距离增加。最后根据实测数据给出了制动初速度和制动距离的关系模型,供后续制动行为分析和相关研究使用。
The research of braking behavior can not only be used in traffic accident treatment, but also can be used in the design and calibration of many automobile safety testing equipment. In this study, 1 314 private car data from 31 cities in China were collected, and the braking behavior data were analyzed. The results show that： the beginning speeds of the normal braking behavior of private cars are in the low-speed range; most of the braking distances that are tested are less than 90 m; braking behavior in differences domestic are different, compared with the northeast, the braking behaviors of the cities in south of Yangtze River have high begin speeds; usually, the driver will adopt conservative driving with reduced initial braking speed to compensate the reduction of the road adhesion coefficient to decrease the braking distance. Finally, based on the measured data, the relationship between the initial braking speed and braking distance was given.
