摘要：

开发了一种占位小、误报少、“四合一”集成的汽车安全辅助驾驶控制系统。该控制系统包括：车道偏离警示系统、前方碰撞预警系统、盲点监测系统以及主动预紧式安全带等 4 种典型辅助驾驶系统。控制决策系统利用控制器局域网通讯协议，基于即碰时间（TTC) 信号，确定控制指令优先级；借助改进的安全带，执行危急提醒和分级预紧功能。在不同气象和照明的条件下，进行了高速公路的实车测试。结果表明：该四合一集成控制系统，能够解决同时报警以及频繁报警问题，可提醒和约束驾驶员，减少驾驶员的误判，从而可降低驾乘人员的损伤风险。

Abstract:

 An integration automotive active-safety assistance-driving system, named four-in-one, was designed with less vehicle-interior-space and with less miss-alarms. The four-in-one system included four typical automotive safety systems, which are lane departure warning system, forward collision warning system, blind spot detection system, and active preload safety belt. A control strategy was developed with a control-instruction priority being determined by controller-area-network (CAN) communication-protocol based on time-to-collision (TTC) signal to complete critical-reminder and grading-pretension by advanced safety belt. A real vehicle with the integration system was tested on highway field in different weathers. The results show that the “four-in-one” system can avoid frequent alarms and simultaneous alarms with driver reminding and restricting with less driver's wrong judgments. Therefore, the injury-risk in traffic accidents can be reduced for drivers and passengers.
