Abstract
An anti-tailgating speedometer comprises a shell, a probe and a processing module. The shell is a two-step-shaped cylinder. The shell comprises a first step portion and a second step portion, wherein the width of the cross section of the second step portion is larger than the width of the cross section of the first step portion. The probe is contained in the first step portion and can emit detection light beams. The processing module is contained in the second step portion and can be in communication connection with the probe. The end, close to the probe, of the shell is open, the probe outward emits the detection light beams through an opening of the shell, and therefore the distance between an automobile and a vehicle behind the automobile can be measured in real time. The processing module obtains the distance of the automobile and the vehicle behind the automobile in real time and processes the distance to generate early warning information. By means of the anti-tailgating speedometer, the velocity of the vehicle behind the automobile can be measured in real time, and the early warning information can be generated, and therefore a driver is reminded of whether the tailgating risk exists or not, and the occurrence rate of tailgating accidents is lowered. Meanwhile, the invention further provides an automobile prompting system with the anti-tailgating speedometer.
