The invention relates to a vehicle automatic emergency braking redundancy control system and method, the system comprises an ADAS system, an IPB integrated braking system and an RBU redundancy braking system, the ADAS system is internally provided with an AEB system and an ESA system; the ADAS system is configured to respond to a fault signal of the IPB integrated braking system and adjust the triggering time of collision detection of the AEB system based on the difference between the maximum braking time delays of the RBU redundant braking system and the IPB integrated braking system; the AEB system is configured to judge whether the vehicle can avoid collision or not and send a braking request to the RBU redundant braking system or send an automatic steering collision avoidance request to the ESA system according to the judgment result of collision avoidance. When the IPB function breaks down, the automatic emergency braking function can still be executed to avoid or relieve collision damage or trigger the ESA function to avoid collision.
本发明涉及一种车辆自动紧急制动冗余控制系统及方法,其系统包括:ADAS系统、IPB集成制动系统和RBU冗余制动系统,所述ADAS系统内设有AEB系统和ESA系统;所述ADAS系统被配置为,响应于IPB集成制动系统的故障信号,基于RBU冗余制动系统与IPB集成制动系统的最大制动时延之差,调整所述AEB系统的碰撞检测的触发时间;所述AEB系统被配置为,判断车辆是否能避免碰撞,并根据避免碰撞的判断结果,向RBU冗余制动系统发出制动请求或向ESA系统发出自动转向避免碰撞请求。本发明实现了IPB功能发生故障时,仍能执行自动紧急制动的功能来避免或减轻碰撞伤害或触发ESA功能来避免碰撞。
