摘　　要：为了设计一种以驾驶人主观意志为主导的城市道路跟驰防撞预警系统,招募驾驶人进行实车试验,获取驾驶人跟驰过程忍受的最小跟车间距对应时刻的车辆运行状态数据,并将这个极限时刻对应的行车状态参数作为预警阈值设计预警系统.预警系统的硬件平台基于STM32F103C8T6主控芯片开发,通过CodeWarrior软件设计预警系统程序.实车试验时,系统采集的预警指标与设定好的系统阈值进行比对,预警指标超出系统阈值,报警模块发出预警声音提醒驾驶人.经过验证,设计的跟驰防撞系统可靠、实用.In order to design an urban road following collision warning system dominated by the subjective will of drivers,drivers are recruited for real vehicle testing.Obtain the vehicle operating status data at the time corresponding to the minimum following distance that the driver can tolerate during the following process,and design a warning system using the corresponding driving state parameters at this moment as the warning threshold.The hardware platform of the warning system is developed based on the STM32F103C8T6 main control chip,and the software program is designed using CodeWarrior software.During the actual vehicle test,the warning indicators collected by the system are compared with the set system threshold.If the warning indicators exceed the system threshold,the alarm module will emit a warning sound to remind the driver.After verification,the designed car following collision avoidance system is reliable and practical.
