汽车自动紧急制动系统控制策略分析

Analysis of control strategies for autonomous emergency braking systems

为降低交通事故的发生概率,减小碰撞损失,对比分析传统自动紧急制动(autonomous emergency braking,AEB)系统控制策略及专用AEB系统控制策略的研究现状,并从驾驶员特性、路面附着因数、天气环境、传感器技术、控制策略5个方面进行优化分析,展望AEB系统未来发展趋势为:结合真实交通事故数据,开发适用于中国交通行车场景的专用AEB系统;采集真实行车场景下油门、制动踏板等数据,针对驾驶员行为特性设计个性化和自适应化AEB系统控制策略;通过建立高精地图与交通事故信息结合的数据集,实现AEB系统控制策略根据历史驾驶数据的自适应调整。

In order to reduce the probability of traffic accidents and minimize collision losses,the research status of traditional autonomous emergency braking(AEB)system control strategies and dedicated AEB system control strategies are compared and analyzed,and optimization analysis is conducted from driver characteristics,road adhesion factors,weather conditions,sensor technology,and control strategies.The future development trend of AEB systems is predicted to be developing dedicated AEB systems for Chinese traffic scenarios by combining real traffic accident data,designing personalized and adaptive AEB system control strategies based on driver behavior characteristics by collecting data from driving scenes such as throttle and brake pedals,achieving adaptive adjustment of AEB system control strategies based on historical driving data by establishing a dataset combining high-maps with traffic accident information.
