Description

Technical Field

[0001] The present invention relates to the technical field of vehicle intelligent transportation, and particularly relates to a method and system for trip sharing and communication, a vehicle-to-vehicle interaction device, and a vehicle. Background Art

[0002] With the rapid development of vehicle intelligent technology, the demand for information interaction between vehicles has increased significantly. During vehicle driving, traditionally, drivers rely on devices such as walkie-talkies or mobile phones for real-time communication. However, such methods have significant drawbacks: on the one hand, drivers need to frequently operate the communication devices manually, resulting in distracted attention and increasing driving safety hazards; on the other hand, vehicles can only obtain their own location information and perform independent path planning. If multi-vehicle location sharing or collaborative navigation is required, it highly depends on the navigation function of mobile devices such as mobile phones, further exacerbating the operation complexity and safety risks.

[0003] In the prior art, there are already solutions for vehicle-to-vehicle voice calls through short-range communication, but their functions are limited to voice interaction and do not involve the real-time sharing of key information such as vehicle location and driving status, making it difficult to meet the comprehensive interaction requirements in multi-vehicle collaborative scenarios. There is also a vehicle location sharing system that proposes to establish a location sharing group of in-vehicle navigation terminals through a server, enabling vehicles to share their own locations and view information of other vehicles on the map, while supporting voice interaction functions. However, this system has the following deficiencies: Dependence on mobile devices: Its in-vehicle navigation terminal needs to rely on a mobile phone or other mobile devices with navigation functions to be realized, requiring additional carrying and configuration of devices, with poor convenience and integration; Safety risks: Relying on handheld device operations easily causes driver distraction, and the connection stability between mobile devices and in-vehicle systems is insufficient, with a risk of communication interruption; Real-time defects: This system only supports the interaction of voice information and lacks real-time communication capabilities, resulting in delays in location sharing and instruction transmission, making it difficult to meet the high-efficiency collaboration requirements in dynamic traffic scenarios.

[0004] Therefore, it is necessary to develop a new method and system for trip sharing and communication, a vehicle-to-vehicle interaction device, and a vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and system for trip sharing and communication, a vehicle-to-vehicle interaction device, and a vehicle to achieve efficient collaboration and safe interaction of trip information between vehicles.

[0006] In a first aspect, a method for trip sharing and communication according to the present invention includes the following steps: The initiating vehicle establishes a trip sharing group and allows at least one other vehicle to access the trip sharing group after passing verification; After the vehicle successfully joins the trip sharing group, based on the starting point and destination information of each vehicle and combined with the V2X environment data, a route is planned for each vehicle, and the route information is broadcast to the trip sharing group for all vehicles in the group to view; Each vehicle in the trip sharing group starts driving according to the route information. During the trip, the vehicle's own navigation interface and the group navigation interface are displayed; at the same time, wireless voice communication can be carried out between the vehicles in the trip sharing group.

[0007] Optionally, the steps of establishing a trip sharing group include: When the initiating vehicle establishes a trip sharing group, a dynamic interaction code is automatically generated; The accessing vehicle joins the trip sharing group after entering the correct dynamic interaction code. By automatically generating the dynamic interaction code by the initiating vehicle, the security of the trip sharing group is increased. Only vehicles that enter the correct dynamic interaction code can join the trip sharing group, effectively preventing unauthorized vehicles from joining. The present invention improves the security and privacy of the trip sharing group, ensuring the legality and credibility of the vehicles in the trip sharing group.

[0008] Optionally, displaying the vehicle's own navigation interface and the group navigation interface specifically means: The left side of the display interface is used as the vehicle's own navigation interface, and the right side of the display interface is used as the group navigation interface; Among them, one or more of the vehicle's current position, driving direction, and estimated arrival time information are displayed in real time on the vehicle's own navigation interface; The group route map is displayed on the right side of the group navigation interface. The group route map includes the real-time positions and route information of each member; various information such as member names and avatars, destination positions, estimated arrival times, remaining mileage, and real-time vehicle speeds are displayed on the information bar on the left side of the group navigation interface. The display interface is divided into left and right parts to display the vehicle's own navigation and group navigation information respectively, enabling the driver to clearly understand the driving conditions of the vehicle and the members of the trip sharing group at a glance.

[0009] Optionally, when planning the route, the route planning mode is also combined. Among them, the route planning mode includes a custom route mode, a collinear mode, and an independent mode; In the custom route mode, the initiating vehicle sets waypoints and destinations, and plans the optimal route in combination with the V2X environment data, and broadcasts it to each member vehicle of the trip sharing group; In the collinear mode, at least two vehicles set different destinations. The initiating vehicle plans the optimal route from its starting point to the farthest destination according to its own starting point and each destination, and in combination with the V2X environment data; In independent mode, each vehicle sets a different destination respectively, and plans its own driving route according to its own starting point and destination, combined with V2X environment data. The present invention provides a variety of route planning modes, which meet the driving requirements in different scenarios and improve the flexibility and efficiency of the journey.

[0010] Optionally, in the custom route mode: The initiating vehicle sets waypoints and a destination, plans the optimal route according to the starting point, waypoints, destination and combined with V2X environment data, and broadcasts the optimal route to the trip sharing group; If the starting points of the vehicles are the same, they start driving according to the optimal route; If the starting points of the vehicles are different, each vehicle plans a driving route to merge into the optimal route according to its own starting point and the nearest waypoint to itself, and drives to the nearest waypoint to itself based on the driving route and then drives according to the optimal route. If the starting points of the vehicles are different, planning a driving route to merge into the optimal route according to its own starting point and the nearest waypoint to itself improves the accuracy and practicability of route planning. Optimize the route planning in the custom route mode, so that each vehicle can merge into the optimal route more smoothly, improving the continuity and comfort of the journey.

[0011] Optionally, in the collinear mode: Each vehicle sets a destination respectively, and there are at least two different destinations; The initiating vehicle plans the optimal route from its own starting point to the farthest destination according to its own starting point, each destination and combined with V2X environment data, and broadcasts the optimal route to the trip sharing group; If the starting points of the vehicles are the same, they start driving according to the optimal route; If the starting points of the vehicles are different, each vehicle plans a driving route to merge into the optimal route according to its own starting point and the optimal route, and the vehicle drives based on the driving route and drives to its own destination according to the optimal route after merging into the optimal route. The initiating vehicle plans the optimal route according to its own starting point, each destination and combined with V2X environment data, improving the efficiency and energy saving of the journey. If the starting points of the vehicles are different, planning a driving route to merge into the optimal route according to its own starting point and the optimal route improves the flexibility and practicability of route planning.

[0012] In a second aspect, a system for trip sharing and communication according to the present invention includes a memory and a controller. A computer-readable program is stored in the memory. When the computer-readable program is called by the controller, it can execute the steps of the method for trip sharing and communication as described in the present invention.

[0013] In a third aspect, a vehicle-to-vehicle interaction device according to the present invention includes a V2X module, a high-precision map module, a main control module, a display module, and a voice module that are interconnected; The V2X module is used to realize information exchange between the vehicle and the environment, including receiving the interaction data of the high-precision map module and transmitting it to the trip sharing group, and receiving V2X environment data; The high-precision map module is equipped with an in-vehicle high-precision map, which is used to update the vehicle's own interaction data to the V2X module, and receive the interaction data of each member in the trip sharing group transmitted by the V2X module; The main control module is used to generate a dynamic interaction code to verify the vehicles joining the trip sharing group when receiving a group creation request from the vehicle. After the establishment of the trip sharing group, based on the departure and destination information of each vehicle, and combined with the V2X environment data, plan a route for each vehicle, and broadcast the route information to the trip sharing group; and process the data information sent by the V2X module and output navigation information, as well as the real-time positions, routes, and destination information of each vehicle in the trip sharing group, and receive and process the instructions of the voice module; The display module is used to display the vehicle's own navigation information, as well as the real-time positions, routes, and destination position information of the vehicles of the trip sharing group members; The voice module is used to realize wireless voice communication between the vehicles in the trip sharing group.

[0014] Optionally, the V2X module includes: A data interaction unit, which is used to transmit the interaction data of the high-precision map module to the trip sharing group through wireless communication technology, and receive information about the surrounding environment; A communication mode switching unit, which is used to automatically switch between two communication modes of cellular communication and direct communication according to network conditions and service requirements; A map information optimization unit, which is used to combine the data information received by the V2X module to refine and optimize the high-precision map information of the high-precision map module in real time. It optimizes the functions and performance of the V2X module, and improves the efficiency and accuracy of information exchange between vehicles.

[0015] In a fourth aspect, a vehicle according to the present invention adopts the vehicle-to-vehicle interaction device as described in the present invention.

[0016] The present invention has the following unexpected beneficial effects: (1) High integration and convenience: The present invention does not need to rely on external mobile devices, and realizes trip sharing and communication through an in-vehicle dedicated communication system, avoiding the trouble of carrying and configuring additional devices, and improving the convenience and integration of the system.

[0017] (2) Enhanced driving safety: By establishing a trip sharing group, real-time sharing of key information between vehicles is achieved, including location, driving status, etc., reducing the frequent manual operations of drivers on communication devices and lowering the distraction risk during driving.

[0021] (4)Flexible and diverse route planning: The present invention provides various route planning modes such as custom route mode, collinear mode, and independent mode to meet the driving requirements in different scenarios.

[0022] In the custom route mode, the initiating vehicle can set waypoints and destinations, and plan the optimal route in combination with V2X environment data to ensure the flexibility and personalization of the driving route.

[0023] In the collinear mode, even if vehicles set different destinations, they can plan the optimal route according to the starting point and the farthest destination to achieve effective collaboration between vehicles.

[0024] (5)Improved user experience: Through the intuitive split-screen navigation interface and rich display of group navigation information in the present invention, drivers can clearly understand the driving status of their own vehicle and the vehicles in the trip sharing group, improving the information acquisition efficiency during driving.

[0025] The setting of the dynamic interaction code increases the security and convenience of the trip sharing group, effectively preventing unauthorized vehicles from accessing.

[0026] In summary, through functions such as real-time communication, location sharing, split-screen navigation, and flexible and diverse route planning, the present invention realizes the efficient collaboration and safe interaction of trip information between vehicles, significantly improving driving safety, collaboration efficiency, and user experience. This system is not only applicable to intelligent driving scenarios but also can play an important role in manual driving scenarios, making important contributions to the intelligence and safety of the overall traffic system.

[0029] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the protection scope of the present invention.

[0030] As Figure 1 shown, in the embodiments of this application, a method for trip sharing and communication includes the following steps: Before the start of the trip, the initiating vehicle establishes a trip sharing group and allows at least one other vehicle to access the trip sharing group after verification. After the vehicle successfully accesses the trip sharing group, a route is planned for each vehicle based on the departure and destination information of each vehicle and combined with V2X environmental data, and the route information is broadcast to the trip sharing group for all vehicles in the trip sharing group to view. Each vehicle in the trip sharing group starts driving according to the route information. During the trip, the navigation interface of the vehicle and the group navigation interface are displayed; at the same time, wireless voice communication can be carried out between vehicles in the trip sharing group.

[0031] like Figure 2 As shown, in a possible embodiment, the steps of establishing a trip sharing group include: When the initiating vehicle creates a trip sharing group, a dynamic interaction code is automatically generated. The connected vehicle joins the trip sharing group after entering the correct dynamic interaction code. The dynamic interaction code has a validity period limit.

[0032] Example: Before the start of the trip, a trip sharing group is established: the initiating vehicle initiates a group establishment request on the vehicle computer, and the main control module 4 generates a six-digit dynamic interaction code through an encryption algorithm and outputs it to the display module 5, allowing one or more vehicles to access the trip sharing group. When the access vehicle initiates an interaction request, the six-digit dynamic interaction code generated by the initiating vehicle must be correctly entered, and the legitimacy must be verified through an encryption algorithm to prevent illegal access. The dynamic interaction code is valid for 5 minutes and automatically expires upon timeout to ensure security. After the interaction verification is completed, the trip sharing group can be automatically created, and the group name can be customized.

[0033] After all vehicles are connected to the trip sharing group, sharing is enabled. At this time, the system will display the interface for selecting the interactive mode. The interactive modes include custom route mode, co-route mode, and independent mode. The initiating vehicle can select different interactive modes according to different application scenarios. After selecting the interactive mode, the trip can be started.

[0034] In a possible embodiment, when planning a path, a path planning mode is also combined, specifically: In the custom route mode, the initiating vehicle sets the waypoints and destination, and plans the optimal route based on V2X environmental data, which is then broadcast to each member vehicle of the trip sharing group.

[0035] In the co-linear mode, at least two vehicles set different destinations. The initiating vehicle plans the optimal route from the initiating vehicle's starting point to the farthest destination based on its own starting point and each destination, combined with V2X environmental data.

[0036] In independent mode, each vehicle sets a different destination and plans its own driving route based on its own starting point and destination and combined with V2X environmental data. The present invention provides multiple path planning modes to meet driving needs in different scenarios and improve the flexibility and efficiency of the journey.

[0037] The following describes the path planning in three interaction modes: In custom route mode: the initiating vehicle sets the waypoint and destination, plans the optimal route based on the starting point, waypoints, destination and V2X environmental data, and broadcasts the optimal route to the trip sharing group. If the starting point of each vehicle is the same, it starts driving according to the optimal route. If the starting points of each vehicle are different, each vehicle plans a driving route that merges into the optimal route based on its own starting point and the waypoint closest to itself, and drives according to the optimal route after driving to the waypoint closest to itself based on the driving route.

[0038] like Figure 6 The following is an example of path planning in custom route mode: Set A as the initiating vehicle, and B, C, D, and E as the access vehicles of the itinerary sharing group. In the custom route mode, the scenario is to set waypoints one, two, three, four, and the destination. In the custom route mode, A sets each waypoint and destination on the vehicle side, and the high-precision map module 3 sends the received locations to the main control module 4. The main control module 4 combines the V2X environmental data to calculate the optimal route at that time and displays it through the display module 5. A can choose the optimal route at this time, or optimize and adjust the optimal route according to personal habits. After the optimal route is selected, A broadcasts the optimal route information to B, C, D, and E members in the itinerary sharing group through the V2X module 6. A, B, C, D, and E start driving according to this route. It is worth noting that A, B, C, D, and E can be the same starting point or different starting points. When A, B, C, D, and E are different starting points, A, B, C, D, and E will all drive to the nearest waypoint (for example) according to the driving route calculated by the main control module 4 of each vehicle. Figure 6 After passing through point A, drive along the optimal route planned in A.

[0039] In the collinear mode: Each vehicle sets its own destination, with at least two different destinations. The initiating vehicle plans the optimal route from its starting point to the farthest destination based on its starting point, each destination, and in combination with V2X environmental data, and broadcasts the optimal route to the trip sharing group. If the starting points of all vehicles are the same, they start driving according to the optimal route. If the starting points of the vehicles are different, each vehicle plans a driving route to merge into the optimal route based on its starting point and the optimal route, and the vehicle drives based on the driving route and then drives to its own destination along the optimal route after merging into the optimal route. The initiating vehicle plans the optimal route based on its starting point, each destination, and in combination with V2X environmental data, improving the efficiency and energy conservation of the trip. If the starting points of the vehicles are different, each vehicle plans a driving route to merge into the optimal route based on its starting point and the optimal route, improving the flexibility and practicality of route planning.

[0040] As Figure 7 shown, it is an example of route planning in the collinear mode: Set vehicle A as the initiating vehicle, and vehicles B, C, D, and E as the access vehicles in the trip sharing group. In the collinear mode, members A, B, C, D, and E can all set different destinations. Assume that A, B, and C set destination one, and D and E set destination two. After vehicle A receives this destination information through the V2X module 6 and transmits it to the main control module 4, the main control module 4 combines the V2X environmental data and calculates the optimal route at that time (conducting a combined route planning for destination one and destination two) and displays it through the display module 5. Vehicle A can select the current optimal route or optimize and adjust this optimal route according to personal habits. After the optimal route is selected, vehicle A broadcasts this optimal route information to each member B, C, D, and E in the trip sharing group through the V2X module 6. Vehicles A, B, C, D, and E start driving according to this optimal route. It should be noted that vehicles A, B, C, D, and E can have the same starting point or different starting points. When vehicles A, B, C, D, and E have different starting points, vehicles A, B, C, D, and E will all drive according to the driving routes calculated by the main control module 4 of each vehicle and drive to the position closest to this optimal route along their respective driving routes and then drive along this optimal route.

[0041] As Figure 8 shown, it is an example of route planning in the independent mode: Set vehicle A as the initiating vehicle, and vehicles B, C, D, and E as the access vehicles in the trip sharing group. Members A, B, C, D, and E can all set different destinations and drive along their respective routes. In this independent mode, A, B, C, D, and E can independently set their own destinations. For example, A, B, and C set destination one, D sets destination two, and E sets destination three. The respective main control modules 4 of A, B, C, D, and E combine the V2X environmental data to calculate the driving routes, and A, B, C, D, and E drive to their respective destinations according to their respective driving routes.

[0042] In a possible embodiment, the vehicle's own navigation interface and the group navigation interface are displayed, specifically: The left side of the display interface is used as the vehicle's own navigation interface, and the right side of the display interface is used as the group navigation interface; among them, the current position, driving direction, and estimated arrival time information of the vehicle are displayed in real time on the vehicle's own navigation interface. The group route map is displayed on the right side of the group navigation interface, and the group route map includes the real-time positions and route information of each member. Multiple pieces of information such as the member name and avatar, destination location, estimated arrival time, remaining mileage, and real-time vehicle speed are displayed on the information bar on the left side of the group navigation interface. In the embodiment of the present application, the display interface is divided into left and right parts to display the vehicle's own navigation and group navigation information respectively, so that the driver can clearly understand the driving conditions of the vehicle and the group members at a glance.

[0043] Example, during the trip, it is displayed in split screen according to Figure 4 as shown. The left side of the display module 5 is the vehicle's own navigation interface, and the right side of the display module 5 is the group navigation interface. There are different group navigation interfaces in different interaction modes, specifically: The group navigation interface in the custom route mode is as shown in Figure 6 as shown, the group navigation interface in the collinear mode is as shown in Figure 7 as shown, and the group navigation interface in the independent mode is as shown in Figure 8 as shown. Among them, the right side of the group navigation interface is the group route map, and the real-time positions and route information of each member are displayed on the high-precision map overview on the right side of the group navigation interface. Information such as the member name and avatar, destination location, estimated arrival time, remaining mileage, and real-time vehicle speed are displayed on the information bar on the left side of the group navigation interface. It should be noted that in order to visualize the member information, the information of each member is represented by different colors, and the real-time positions and route information of the members are also marked with corresponding different colors on the high-precision map overview of the group navigation interface.

[0044] In a possible embodiment, the present method can perform voice call interactions. Through the V2X module 6, wireless voice calls can be achieved between vehicles within the travel sharing group. The user can click on the display module 5 or issue a voice command to activate the voice call function. After activation, the voice module 7 collects the user's voice through the microphone array for communication transmission and performs voice broadcast through the audio device. After receiving the voice data, the main control module 4 uses an echo cancellation algorithm to reduce the interference of the in-vehicle environmental noise on the call quality, and shares the processed information to each vehicle in the travel sharing group through the V2X module 6. The system controls the voice communication delay within 500 ms to ensure smooth call quality.

[0045] In a possible embodiment, the present method supports voice control, and the main control module 4 can make response processing based on the command information collected by the voice module 7. For example, when the user says "Set the destination to xx", the main control module 4 processes the address command information collected by the voice module 7, and after identifying the specific destination information, combines it with the V2X environmental data, and calculates the optimal route at that time through an algorithm and displays it through the display module 5.

[0046] In a possible embodiment, the display module 5 updates the position information once per second to ensure real-time performance.

[0047] In a possible embodiment, the main control module 4 receives the position information of each vehicle within the travel sharing group obtained by the V2X module 6, and after encrypted information processing, combines it with DMD (Digital Micromirror Device) technology to project the position prompts of each vehicle within the travel sharing group on the HUD of the display module 5 to enhance driving perception.

[0048] In a non-driving scenario, the user can also mark a location on the high-precision map module 3, specifically: Click or use voice control to mark a location on the display module 5. The high-precision map module 3 can record the current location of the vehicle as the marked location, and the user can customize the name of the marked location. See Figure 5 . When selecting a destination or waypoint, it can also be directly selected.

[0049] In a possible embodiment, after the trip ends, the system defaults to saving the historical group, and the group name can be customized. When starting the next trip, a dynamic interaction code needs to be verified. After successful verification, the information within this travel sharing group continues to be shared.

[0050] The usage scenarios of the present method are extensive and can meet most usage requirements, such as: 1. Fleet collaborative driving: Multiple vehicles share the destination, and the system automatically plans the formation and following distance; The positions and driving states of each vehicle are displayed in split screens, and voice command and dispatch are supported.

[0051] 2. Emergency rescue: The accident vehicle broadcasts a distress signal to surrounding vehicles, and the real-time position information of the rescue vehicle is displayed on a split screen; the system automatically plans the optimal rescue route and synchronizes it to the rescue vehicle.

[0052] 3. Daily travel and tourism: Users share their travel itineraries with their friends' vehicles, and the positions and driving information of each other are displayed on a split screen, and voice calls are supported.

[0053] This system has information security. Vehicles in the itinerary sharing group need to enter the correct six-digit dynamic interaction code within 5 minutes to enter the itinerary sharing group for information interaction. The system provided by the present invention has convenient operation. By using the split-screen navigation display technology, the itinerary information of the vehicle itself and the connected vehicles is synchronously displayed. The system provided by the present invention has strong interactivity. Real-time calls can be made within the itinerary sharing group (the call content is encrypted by the algorithm of the main control module 4 and will not be leaked).

[0054] As Figure 2 shown, in the embodiment of the present application, a system for itinerary sharing and communication includes a memory 1 and a controller 2. A computer-readable program is stored in the memory 1. When the computer-readable program is called by the controller 2, it can execute the steps of the method for itinerary sharing and communication in the embodiment of the present application.

[0055] In the embodiment of the present application, for a vehicle to implement the method for itinerary sharing and communication described in the embodiment of the present application, each vehicle needs to be equipped with a vehicle-to-vehicle interaction device.

[0056] As Figure 3 shown, a vehicle-to-vehicle interaction device includes a V2X module 6, a high-precision map module 3, a main control module 4, a display module 5, and a voice module 7 that are connected to each other. Among them, the V2X module 6, the high-precision map module 3, the main control module 4, the display module 5, and the voice module 7 are not limited to existing on one controller circuit at the same time, and can also be distributed on multiple controller circuits to cooperate to complete the functions of this system.

[0057] The following is a detailed introduction to each functional module: High-precision Map Module 3: It is equipped with an in-vehicle high-precision map. In the marked location scenario, the in-vehicle high-precision map can record the vehicle's location in detail and use it as a marked location. In the interaction scenario, the vehicle's interaction data is updated to the V2X module 6 every second. The V2X module 6 transmits the interaction data to the vehicle-to-vehicle interaction devices of all member vehicles in the trip sharing group. At the same time, the interaction data received by the V2X module 6 on this vehicle, after being processed by the main control module 4, is clearly and explicitly displayed by the display module 5 to show the interaction information of each member. The interaction data includes information such as member name, real-time location and route, destination location, estimated arrival time, remaining mileage, and real-time vehicle speed. The real-time location and route information of each member are displayed on the high-precision map overview of the group navigation interface, and information such as member name and avatar, destination location, estimated arrival time, remaining mileage, and real-time vehicle speed are displayed in the left information column of the group navigation interface. It should be noted that in order to visualize member information, the information of each member is represented by different colors, and the real-time location and route information of the member are also marked with corresponding different colors on the high-precision map overview of the group navigation interface.

[0058] V2X Module 6: It realizes information exchange between the vehicle and the environment (including pedestrians, other vehicles, roadside infrastructure, and the network) through wireless communication technology. The V2X module 6 receives the interaction data from the high-precision map module 3 and transmits it to the vehicle-to-vehicle interaction devices of the members of the trip sharing group through wireless communication technology. At the same time, the V2X module 6 receives V2X environmental data to improve the environmental perception ability and lay a foundation for the optimal route planning and intelligent transportation. Preferably, the current V2X module 6 has been equipped with 5G technology to provide ultra-low latency and high reliability for data interaction. The communication modes of the V2X module 6 include two communication methods: cellular communication (Uu interface) and direct communication (PC5 interface). Cellular communication enables the vehicle to access the core network through a 5G base station to achieve wide-area communication. It is suitable for scenarios with wide-area communication requirements, high bandwidth, low mobility, and stable cellular coverage; direct communication is for the vehicle to directly communicate with surrounding devices (other vehicles, roadside units, pedestrian terminals) without relying on a base station. It is suitable for scenarios with low-latency, high-reliability requirements, no network coverage or weak network environment, short-distance high-speed communication, and emergency communication.
