The invention discloses a vehicle A-pillar blind area detection system and method, cameras and displays are arranged at left and right A-pillars and are matched with radars at left and right side fender plates, and after the radars detect blind area targets, the blind areas with risks can be accurately fed back to drivers through built-in acousto-optic devices of the displays, so that the blind area detection accuracy is improved. Whether the automatic emergency braking system is triggered to work under the working condition or not is decided according to radar feedback, blind area images and braking operation response of a driver, so that the driver is assisted in braking the vehicle; a camera mounting hole is reserved in an outer plate of the A column, holes do not need to be reserved in an inner plate and a reinforcing plate, and the safety of a vehicle body is ensured while the strength of the A column is considered. Through radar detection and visual auxiliary monitoring of the corresponding blind area, the condition of the area shielded by the A column can be reliably obtained, automatic emergency braking can be executed when a driver does not recognize the collision risk of the blind area of the A column and does not take braking measures in the first time, and accidents are effectively avoided.
本发明公开了一种车辆A柱盲区检测系统及检测方法,通过在左右A柱处配置摄像头及显示器,并与左右侧翼子板处的雷达进行配合,雷达探测到盲区目标物后可通过显示器内置声光器件为驾驶员准确反馈当前存在风险的盲区,并通过雷达反馈、盲区影像及驾驶员的制动操作响应,决策是否在此工况触发自动紧急制动系统工作,以便辅助驾驶员刹停车辆;其中,在A柱外板处预留摄像头安装孔,无需在内板及加强板上留孔,在兼顾A柱强度的同时确保车身的安全性。本发明通过对应盲区的雷达探测及视觉辅助监测,能够可靠获得被A柱遮挡的区域情况,并且在驾驶员没有识别到A柱盲区碰撞风险,未第一时间采取制动措施时,能够执行自动紧急制动,有效避免事故发生。
