The invention relates to a backward early warning method and system for preventing rear-end collision. The method comprises the following steps that 1, the average deceleration value of a vehicle in a preset time period is calculated; 2, whether the average deceleration value is larger than a preset threshold value or not is judged; if the threshold value is smaller than the threshold value, the backward early warning function is inhibited from being started; if yes, executing the next step; 3, whether a vehicle comes behind the vehicle or not is judged, and if not, starting of the backward early warning function is restrained; if the vehicle comes, executing the next step; step 4; whether an accelerator pedal is stepped down or not is judged, and if the accelerator pedal is stepped down, starting of the backward early warning function is restrained; and if the accelerator pedal is not stepped down, a backward early warning function is triggered. The invention further discloses a system for implementing the method. The backward early warning function can be started under necessary and emergency conditions to remind a rear vehicle of danger in front, so that the effect of reminding the rear vehicle to slow down or avoid is achieved, and the warning effect is better than that of frequently starting early warning.

    本发明涉及一种防追尾的后向预警方法及其系统,方法包括如下步骤:步骤一:计算车辆在预设的时间段内的平均减速度值;步骤二:判断平均减速度值是否大于预设的阈值;若小于阈值,则抑制后向预警功能开启;若大于阈值则执行下一步;步骤三:判断车辆后方是否有来车,若没有来车则抑制后向预警功能开启;若有来车则执行下一步;步骤四;判断油门踏板是否被踩下,若被踩下则抑制后向预警功能开启;若油门踏板没有被踩下则触发后向预警功能。还包括实现所述方法的系统。后向预警功能在必要且紧急的情况下才会启动,提醒后车前方危险,进而达到提醒后车注意减速或者避让的效果,示警效果比频繁启动预警更好。
