摘要：

       为了促进汽车自动紧急制动（AEB）技术朝着更加安全与高效的方向发展，该文从AEB系统的工作原理、发展历程、应用现状、法规标准等方面，综述了AEB 技术的研究进展，总结了与AEB系统综合性能密切相关的关键技术，包括AEB系统避撞策略、制动执行机构和环境感知机构。研究表明：自动紧急制动系统能够有效避免或者缓解追尾碰撞，可提高车辆主动安全性能；受制于目前制动执行技术和前端感知技术水平，AEB系统无法实现汽车在更高车速范围以及更复杂多交通场景下的完全避撞。自动紧急制动系统未来研究的重点在于：复杂多交通场景下避撞策略综合性能优化；基于更快响应时间目标的制动执行机构研发；危险行驶工况下与多种主动安全技术的深度融合及协调控制。

Abstract:

A research progresses on the working principle, development path, application status and regulation of the autonomous emergency braking (AEB) technology were introduced to promote the car’s autonomous emergency braking technology to be safer and more efficient. The key technologies related to the
comprehensive performance of AEB system were summarized, including collision avoidance strategy, braking execution technology and front-end perception technology. The results show that AEB system can effectively avoid or mitigate collision, which can greatly improve the vehicle's active safety performance. However, AEB system can’t avoid any collision at higher vehicle speed and more complex traffic scenarios on account of low level braking execution technology and front-end perception technology. The technology focus for AEB will be comprehensive performance optimization of collision avoidance strategy in more complex traffic scenarios, the development of brake actuators based on shorter response time objectives, and the deep integration and the coordinated control of multiple active safety technologies under dangerous driving conditions.
