The invention provides a safety prompting method and system for preventing vehicle rear-end collision and a vehicle-mounted terminal. The method comprises the steps of receiving a video signal of a front running vehicle acquired by an image acquisition device; identifying the relative distance between the current vehicle and the front running vehicle according to the video signal; judging whetherthe relative distance is not greater than a safety vehicle distance or not; and if so, sending a safety prompt signal to a head-up display device so as to enable the head-up display device to projectsafety prompt information to a front windshield of the current vehicle. According to the invention, a camera is used for monitoring the driving process of the front vehicle, the safety distance between the two vehicles is calculated according to the relative distance and the relative speed of the current vehicle and the front vehicle, and when the distance is too short, the HUD reminds and warns adriver to slow down to keep the safety distance through red highlight characters, so that the vehicle rear-end collision accident is avoided, and the driving safety is improved.
本发明提供防止车辆追尾的安全提示方法、提示系统、及车载终端。所述方法包括:接收由图像采集装置获取的前方行驶车辆的视频信号;根据所述视频信号识别出当前车辆与所述前方行驶车辆的相对距离;判断所述相对距离是否不大于安全车距;若是,则向平视显示装置发送安全提示信号,以令所述平视显示装置将安全提示信息投射于当前车辆的前挡玻璃上。本发明利用摄像头监测前方车辆的行驶过程,通过本车与前车的相对距离和相对速度计算得到两车之间的安全距离,距离过近时HUD就会用红色高亮文字提醒和警示驾驶员需要减速来保持安全间距,从而避免出现车辆追尾事故,提高行车安全性。
