Description

Technical Field

[0001] The present invention relates to the field of road traffic safety management, vehicle wireless communication technology, intelligent connected vehicles and other related fields, and in particular to a highway vehicle communication method based on C-V2X. Background Art

[0002] With the increase in the number of cars, traffic accidents on the road are frequent, especially on highways. Once an accident occurs, it often leads to serious consequences such as a chain reaction. At present, although there are a variety of traffic information release systems, such as broadcasting and SMS notifications, when an accident occurs, the response speed and coverage of these systems are limited. They cannot promptly and effectively notify surrounding vehicles and push the best driving strategy in real time, resulting in frequent secondary accidents. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a highway vehicle communication method based on C-V2X, which utilizes the vehicle wireless communication technology of cellular network communication technology to achieve low-latency and high-reliability information sharing among multiple vehicles and reduce the occurrence of vehicle accidents.

[0004] The technical solution of the present invention is:

[0005] A highway vehicle communication method based on C-V2X allows vehicles to automatically join a temporary virtual chat room within a range of n kilometers, where n>0, to achieve vehicle driving status information sharing; based on the driving status of each vehicle in real time, the best driving advice is provided to other vehicles, and if a traffic accident occurs in the area, an alarm is immediately issued to all member vehicles.

[0006] Furthermore,

[0007] They can also report accident details to management in a timely manner.

[0008] Going further,

[0009] The specific steps include vehicle identification and networking, vehicle behavior prediction notification, accident monitoring and alarm, and alarm reception and reporting.

[0010] Going further,

[0011] Vehicle identification and networking: When the vehicle is driving, it will automatically identify vehicles that are also equipped with C-V2X devices within a range of n kilometers. Based on the vehicle's location information, a virtual chat room is automatically created. All vehicles in the same area will be invited to join. Vehicles in the chat room will regularly broadcast the vehicle's status, speed, velocity and direction information through the C-V2X communication module.

[0012] Vehicle behavior prediction notification, based on the speed, location, and direction information of all vehicles in the chat room in real time, provides the optimal driving strategy for the vehicle.

[0013] When vehicle A brakes, changes lanes or merges into a fork in the road, the optimal driving strategy is pushed to all vehicles in the chat room based on information such as the distance and speed between vehicle A and other vehicles. This includes pushing to vehicle A whether the operation can be completed, and pushing to other vehicles to slow down, change lanes or maintain driving strategies.

[0014] Accident monitoring and alarm,When an accident occurs to a vehicle in the chat room, an alarm message containing the accident location, time, and impact range is generated and sent to all vehicles in the chat room. The vehicle user interface in the chat room displays the alarm information, reminds the driver, and recommends the optimal driving strategy.

[0015] Alarm reception and reporting, proactively sending accident details to management, including location, time and accident type information.

[0016] The beneficial effects of the present invention are

[0017] 1) Reduce the occurrence of accidents: The system can detect accidents in real time and notify surrounding vehicles immediately, reducing the risk of secondary accidents.

[0018] 2) Enhance rescue efficiency: By promptly reporting the accident to the traffic management department, the rescue response time can be accelerated.

[0019] 3) Reduce driving risks: Drivers can know the road conditions ahead in advance and make reasonable driving decisions based on the driving strategies pushed by the system to improve overall road traffic efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the workflow of the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The present invention provides a highway vehicle communication method using C-V2X (cellular vehicle-to-everything wireless communication) technology to achieve low-latency, high-reliability information sharing between multiple vehicles, quickly notify surrounding vehicles when an accident occurs, and report the accident to the traffic management department in a timely manner.

[0023] The present invention includes vehicle identification and networking, vehicle behavior prediction and notification, accident monitoring and alarm, alarm reception and reporting steps. Based on the above ideas, the implementation steps are as follows:

[0024] Step 1: When the vehicle is driving, it will automatically identify vehicles within a range of n kilometers that are also equipped with C-V2X equipment. Based on the vehicle's location information, the system automatically creates a virtual "chat room" and all vehicles in the same area will be invited to join. Vehicles in the "chat room" regularly broadcast information such as the vehicle's status, speed, velocity and direction through the C-V2X communication module.

[0025] Step 2: The system proposes the best driving strategy for the vehicle in real time based on the speed, position, direction and other information of all vehicles in the "chat room". For example, when vehicle A brakes, changes lanes or merges into a fork in the road, the system pushes the best driving strategy to all vehicles in the "chat room" based on the distance, speed and other information between vehicle A and other vehicles. For example, it pushes to vehicle A whether it can complete operations such as changing lanes, and pushes to other vehicles strategies such as slowing down, changing lanes or keeping moving.

[0026] Step 3: When an accident occurs to a vehicle in the "chat room", an alarm message containing the accident location, time and possible impact range is generated and sent to all vehicles in the "chat room". The vehicle user interface in the "chat room" displays the alarm information, reminds the driver through sound or vibration, and recommends the optimal driving strategy.

[0027] Step 4: The system will proactively send accident details to the highway traffic management department, including location, time, and accident type. The traffic management department can take prompt measures to dispatch rescue teams and improve rescue efficiency.

[0028] The above description is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
