Description

technical field [0001] The invention relates to the field of automobile safety equipment, in particular to a wireless vehicle speed display warning device. Background technique [0002] With the increase of the number of cars in our country, the incidence of car accidents on highways is also increasing simultaneously. According to statistics, 90% of the accidents are due to rear-end collisions. Rear-end collisions generally occur when cars collide with large trucks when going uphill or when they are going downhill. The truck rear-ends the car. [0003] From the perspective of the driver at the rear, it is difficult to judge the speed status of the vehicle ahead, or even the vehicle ahead. When a car is driving behind a large truck, it is impossible to predict the state of the road ahead of the large truck due to the obstructed view. In an emergency, after taking emergency measures, the large truck does not have enough reaction time as the rear vehicle, and it is impossible ...

AI Technical Summary

Problems solved by technology

[0004] The electronic vehicle speed display has solved the problem of completely displaying the vehicle speed on the LED display, but it is not very convenient to popularize this display for cars, and it is necessary to modify the cable settings to a large extent. The scope of application is small and it is not easy to popularize.
