The invention discloses a rear vehicle distance early warning method and system and a vehicle, and the method comprises the steps: obtaining the driving speed of a vehicle, and obtaining a first distance between the vehicle and a rear vehicle if the driving speed meets a preset condition; if the first distance is smaller than a preset dangerous distance range, playing an early warning signal of a first degree; if the first distance is larger than or equal to the preset danger distance range and smaller than the preset early warning distance range, a second distance between the vehicle and the rear vehicle is obtained after preset time; according to the first distance, the second distance and the preset time, the relative speed of the rear vehicle relative to the vehicle is obtained through calculation, if the relative speed is larger than or equal to 0, a second-degree early warning signal is played, and otherwise, a third-degree early warning signal is played. According to the invention, the vehicle distance between the vehicle and the rear vehicle is detected by using the reversing camera on the premise of not increasing the number of parts of the vehicle, and early warning reminding of different degrees is carried out according to the size of the vehicle distance.
本申请公开了一种后车车距预警方法、系统及车辆,所述方法包括:获取本车的行驶速度,若所述行驶速度满足预设条件,则获取本车与后车的第一距离;若所述第一距离小于预设危险距离范围,则播放第一程度的预警信号;若所述第一距离大于或者等于预设危险距离范围且小于预设预警距离范围,则在预设时间后获取本车与后车的第二距离;根据所述第一距离、所述第二距离和所述预设时间计算得到后车相对于本车的相对速度,若相对速度大于或者等于0,则播放第二程度的预警信号,否则,播放第三程度的预警信号。本发明利用倒车摄像头,在不增加汽车零部件数量前提下,完成本车与后车车距检测,并根据车距大小进行不同程度的预警提醒。
