摘要
驾驶员制动反应时间和制动行为习惯直接影响车辆行驶安全性和乘坐舒适性。目前安全车距计算方法较少考虑制动行为习惯对安全车距影响。在基于车辆动力学的安全车距模型基础上,优化驾驶员反映时间计算方法,提出制动行为习惯模型并确定相关参数取值范围,建立了考虑制动行为习惯的网联车安全车距模型。实验表明,模型能够计算更为合理的安全车距,使后车驾驶员及时获取前车行驶意图,缩短制动反映时间,提高乘坐舒适性。
Driver’s braking reacting time and braking habits are two important factors affecting driving safety and driving comfort.The safe distance calculation method ignores the driver’s braking habits.This research can improve the calculation of the driver’s braking reacting time through safe distance calculation based on vehicle dynamics.The mathematics model of driver’s braking habits was built.Its corresponding parameters was determined.The safe distance from on-board network calculation considering braking habits was also built.The vehicle test results show that,the models in the research could calculate the safe distance more reasonable and make the driver behind get the braking intention of the front vehicle in time.The driver’s braking reacting time is deceased and the driving comfort is improved.
