The invention discloses a self-adaptive sensitivity adjustment autonomous emergency braking method and system, and belongs to the technical field of vehicle-mounted intelligent driving assistance. After a fatigue monitoring system and an AEB automatic emergency braking system work normally and meet a specified operation interval, a camera is used for recognizing the eyeball position so as to judge the sight range of human eyes; the driving track of the vehicle is judged through the EPS steering auxiliary system and the vehicle information on the CAN bus, a target vehicle is recognized through the ADAS environment perception sensor, and parameters of the target vehicle are calculated; and when the target vehicle is not in the human eye sight range and the target vehicle is in the vehicle driving track range, the sensitivity of the AEB automatic emergency braking system is improved. According to the method, the sensitivity of the AEB function is adjusted by judging the attention range of the driver through an existing fatigue monitoring system on the vehicle or a semi-automatic control mode after active operation of the driver, and vehicle control better conforming to the driving intention and the use scene is achieved.

    本发明公开了一种自适应灵敏度调节自主紧急制动方法及系统,属于车载智能驾驶辅助技术领域,在疲劳监测系统及AEB自动紧急制动系统均正常工作,且均满足规定的运行区间后,通过摄像头识别眼球位置以判断人眼视线范围;通过EPS转向辅助系统及CAN总线上的车辆信息判断车辆行驶轨迹,通过ADAS环境感知传感器识别目标车辆,并推算出目标车辆的参数;在目标车辆不在人眼视线范围,且目标车辆在车辆行驶轨迹范围时,提高AEB自动紧急制动系统灵敏度。本发明通过车辆上已有的疲劳监测系统,或驾驶员主动操作后的半自动控制模式,通过判断驾驶员的注意力范围,来调节AEB功能的灵敏度,实现更加贴合驾驶意图和使用场景的车辆控制。
