The invention relates to an automobile tail speed display method, which is characterized in that a display device is arranged at the tail of an automobile and is connected with an output port of an automobile body controller; a vehicle speed signal detected by the vehicle speed sensor is transmitted to the vehicle body controller, the vehicle body controller calculates vehicle speed change values, and if the absolute value of the adjacent speed change values is larger than or equal to a set value, the vehicle body controller transmits the value obtained after the vehicle speed changes to the display device. And the display device displays the real-time speed after the vehicle speed is changed. By means of the display method, the real-time speed change of the road vehicle can be displayed, the rear vehicle can conveniently recognize the state of the front vehicle and pre-judge in advance, and traffic safety accidents can be effectively reduced.

    本发明涉及一种汽车尾部速度显示方法,在汽车尾部设置显示装置,显示装置与车身控制器的输出端口连接;车辆速度传感器检测的车辆速度信号传输给车身控制器,车身控制器对车辆速度变化值进行计算,若相邻速度变化值的绝对值大于等于设定值,则车身控制器将车辆速度变化后的数值传递给显示装置,由显示装置显示车速变化后的即时速度。通过本发明的显示方法,能够展示道路车辆的实时速度变化,便于后车识别前车状态,提前预判,能够有效减少交通安全事故的发生。
