Background
With the development of technology and the improvement of living standard of people, vehicles are popularized to enter thousands of households. However, as the number of vehicles increases, vehicle safety accidents also rise straight.
For example, in some scenes, a highway has the characteristics of large traffic flow, high driving speed and the like, so that if a vehicle in driving collides or suddenly stops due to road factors, human factors or weather factors, serious traffic accidents can be caused, secondary accidents are possibly brought, and great loss is caused to life and property of people. Highway traffic accidents are classified into rear-end collisions, fixed objects, vehicle rollover, side collisions, scraping, vehicle crash, fire and the like, wherein the rear-end collisions, fixed objects and side collisions are the main forms of accidents. Especially, in the prior art, information interaction among vehicles is lacked, and when the vehicles are in emergency, other vehicles cannot be reminded in time to avoid danger, so that secondary accidents and the like are easily caused.
