In recent years, rear-end collision of highway accidents occur frequently , and the car rear-end collision warning system in addressing highway traffic safety with good prospects , thus causing the researchers' attention. In this paper, build a safer car following model , based on the design of the system structure. Alarm system uses twice , the first time for the reminder alarm , using light alarm ; hazard warning for the second time , the use of lighting , sound, dual alarms. In the build automotive communications network (CAN) , based on the design of the information collection subsystem that is responsible for the acquisition and processing of sensor information and sent to the main control unit subsystems , to meet the real-time data exchange and reliability ; and use C language data collection procedures, complete the calculation from the vehicle speed , steering , braking, throttle position information collection ; designed a real vehicle road experimental program conducted several rounds of real vehicle experiments . Experimental results show that : the development of the system and the hazard warning alert alarm response timely and effective ; system alarm suppression effect.
