Description
Technical Field
The application relates to the technical field of 5G, in particular to a lane change early warning method and a lane change early warning system based on a 5G technology, and a vehicle and a server of the lane change early warning system based on the 5G technology.
Background
With the continuous improvement of living standard, automobiles are more and more common in the life of people, and gradually become one of indispensable vehicles in the life of people in cities and villages.
Meanwhile, people no longer simply define the automobile as a transportation tool and a travel tool, and the requirements on the aspects of safety, environmental protection, comfort, entertainment and the like of the automobile are increasing. The rapid increase of the demands in these aspects leads to increasingly prominent problems of shortage of spectrum resources, crowded frequency bands, safety and the like of vehicle-mounted communication. With the rapid development of the fifth generation mobile communication (5G), the current car networking problem can be effectively solved through the performances of low time delay, high reliability, efficient spectrum utilization and the like, so that the implementation and deployment of the 5G car networking are imperative.
On the other hand, in the modern transportation process, drivers of vehicles often need to judge the running conditions of other vehicles around the drivers of vehicles and adjust their own running behaviors to avoid the collision of the vehicles. However, drivers generally judge the driving conditions of other vehicles around through vision, and at some corners or intersections, due to the obstruction of the sight line, the driving condition information of other vehicles cannot be acquired, so that vehicle collision often occurs, and serious personal and property loss is caused.
For example, in the case of rear-end collisions, many drivers know that the chain reaction generated by the rear-end collisions occurring on the express way is the strongest: because the vehicle speed is generally fast, once two vehicles collide with each other, the rear vehicles are likely to be linked together, which is a common phenomenon called 'vehicle crossing'. The rear-end collision is caused by the fact that a driver of a rear vehicle is not concentrated, and serious consequences can be brought even in the moment. Some drivers are used to make a call while driving, want things empty in a sky and horse, smoke or even eat, and the like, and when an emergency occurs, the drivers are affected to take corresponding measures in time. Therefore, since you choose to drive in the motorway, it is not distracted for one second. A phenomenon is also often encountered in motorways: the vehicles in all lanes are running normally, and suddenly one vehicle slows down, and the driver may turn the lane to the right by turning on the light, because the driver may just think to go out at the exit. Therefore, the following vehicles must be braked sharply one by one, several lanes are blocked successively, and even serious rear-end accidents occur.
In addition, when a vehicle is running, a driver receives the stimulation of the road surface and the flowing scenery for a long time in the vision, the stereoscopic impression of the vision is gradually reduced, and the estimation of the distance is easy to deviate. In addition, in the driving process, the farther the distance to the front of the driver is seen by the eyes, the more easily the problems of low estimated vehicle speed and insufficient holding distance with the front vehicle occur.
The driver has a small following distance to the vehicle in front of the same lane, and has a small distance to the vehicle behind the adjacent lane when crossing the lane or has a small distance to the vehicle to cross the lane when changing the lane because of careless control, which is the root cause of the vehicle collision accident.
In summary, lane change is one of the indispensable operations for driving a motor vehicle, and is also a technology which is not easy for a driver to grasp, many drivers often try to change lanes on a road by feel without the intention of changing lanes, and if the drivers do not go in and go back, a dragon is drawn on the road, thus threatening traffic safety. Even, some drivers have poor control over the timing, angle and speed of lane change, and blindly change lanes, which leads to traffic accidents such as collision.
