The invention discloses a control method of an automatic emergency braking system considering expected function safety, which comprises the following steps of: 1, performing parametric modeling on a'ghost probe 'scene by considering the performance insufficiency of AEB in a specific scene to obtain the maximum theoretical initial speed of complete collision avoidance; 2, identifying a'ghost probe 'in an AEB scene library, and giving out early warning and even actively decelerating when the vehicle enters a possible'ghost probe' scene; 3, establishing transverse and longitudinal risk state assessment strategies in a ghost probe scene based on expected function safety; and the 4AEB realizes the braking action. According to the method, the'ghost probe 'scene is parameterized through mathematical modeling, the judgment criterion and the risk assessment strategy of the'ghost probe' scene are established, and the AEB control method considering the expected function safety is designed, so that the traffic safety is ensured.

    本发明公开了一种考虑预期功能安全的自动紧急制动系统的控制方法,其步骤包括:1考虑特定场景下AEB的性能不足,将“鬼探头”场景进行参数化建模,获得完全避撞的最大理论初速度;2在AEB场景库中识别“鬼探头”,并在车辆进入可能的“鬼探头”场景时发出预警,甚至主动减速;3基于预期功能安全,建立“鬼探头”场景下横向和纵向的风险状态评估策略;4AEB实现制动动作。本发明通过数学建模将“鬼探头”场景参数化,建立了“鬼探头”场景的判断准则和风险评估策略,设计了考虑预期功能安全的AEB控制方法,从而保证了交通安全。
