The invention provides a vehicle braking early warning method. The vehicle braking early warning method comprises the steps of detecting the distance L1 between the foot of a user and a brake pedal; transmitting the distance L1 to a controller and comparing the distance L1 with a numerical value L2 stored in the controller; if L1 is larger than L2, executing the first step, and if L1 is smaller than or equal to L2, detecting the distance L3 between the vehicle and an obstacle in front of the vehicle; transmitting the distance L3 to the controller and comparing the distance L3 with a numerical value L4 stored in the controller; and if L3 is greater than L4, returning to the first step, and if L3 is less than or equal to L4, lightening a brake lamp. According to the method, the lighting opportunity of the tail brake lamp can be advanced by about one second, and the one second can avoid many traffic accidents.
本发明提供了一种车辆制动提前预警方法,包括:检测用户脚部与制动踏板的距离L1;将距离L1传输到控制器并与控制器中存储的数值L2进行比较;若L1大于L2则返回到第一步,若L1小于等于L2则检测车辆与车前障碍物之间的距离L3;将距离L3传输到控制器并与控制器中存储的数值L4进行比较;以及若L3大于L4则返回到第一步,若L3小于等于L4则点亮刹车灯。该方法可以将尾部刹车灯点亮的时机提前约1秒,这1秒可以避免很多交通事故的发生。
