摘 要：
随着智能驾驶辅助系统的迅猛发展,AEB(Autonomous Emergency Braking)作为智能驾驶辅助系统的重要组成部分已经在部分车型上得以配置。AEB系统的工作效能直接关系到驾乘人员的生命安全。基于目前主流的两种AEB控制模型(碰撞时间倒数模型和安全距离模型)通过Pre Scan、Carsim和MATLAB软件联合仿真分析其在各种工况下的制动效能。通过分析车速与车距之间的关系表明,在车速低于60 km/h时,碰撞时间倒数模型不仅具有较高的制动稳定性还有较好的制动舒适性,而车速高于60 km/h时,安全距离模型的制动稳定性较高。

摘 要：
With the rapid development of intelligent driving assistance system, AEB(autonomous emergency braking), as an important component of intelligent driving assistance system, has been configured on some types of vehicles. Working efficiency of AEB system is directly related to the life safety of occupants. Based on the two main control models of AEB(time to collision inverse model and safe distance model), its braking efficiency under various working conditions is analyzed by combined simulation of PreScan, Carsim and MATLAB softwares. The analysis of the relationship between vehicle speed and vehicle distance shows that time to collision inverse model has better braking stability and better braking comfort when the speed is below 60 km/h, while safety distance model has higher reliability of braking when the vehicle speed is over 60 km/h.
