Description

Technical Field

[0001] This application belongs to the field of intelligent transportation technology, specifically relating to an emergency vehicle priority passage method, an emergency vehicle priority passage device, a computer-readable medium, and an electronic device. Background Technology

[0002] Fire trucks, ambulances, and other emergency vehicles have priority on the road when performing their duties, and ordinary vehicles should give way to them.

[0003] Currently, yielding to emergency vehicles primarily involves regular vehicles filtering emergency vehicle messages to identify those located within the affected area. Regular vehicles then prioritize these emergency vehicles, calculating their arrival time and distance to grant them right-of-way. However, this method suffers from the potential abuse of "emergency vehicle priority." Emergency vehicles can trigger the broadcast of emergency messages via their onboard devices, and regular vehicles cannot accurately determine whether an emergency vehicle is on a mission. If an emergency vehicle is not on a mission, it still enjoys priority, which is unfair to other regular vehicles. Summary of the Invention

[0004] The purpose of this application is to provide an emergency vehicle priority passage method, an emergency vehicle priority passage device, a computer-readable medium, and an electronic device that can overcome the problem of emergency vehicles abusing their right-of-way in related technologies.

[0005] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0006] In a first aspect, embodiments of this application provide a method for prioritizing emergency vehicle passage. The method includes: receiving a request message sent by an emergency vehicle service platform and reviewing the request message; after the review is passed, sending identification information corresponding to a target emergency vehicle to the emergency vehicle service platform; determining a target roadside unit based on the request message and generating a first priority passage message based on the request message and the identification information; and sending the first priority passage message to the target roadside unit, wherein the first priority passage message is used to instruct ordinary vehicles within the signal coverage area of ​​the target roadside unit to give way to the target emergency vehicle after receiving vehicle information of the target emergency vehicle.

[0007] Secondly, embodiments of this application provide an emergency vehicle priority passage device, which includes: an approval module for receiving a request message sent by an emergency vehicle service platform and approving the request message; a sending module for sending identification information corresponding to a target emergency vehicle to the emergency vehicle service platform after the approval is passed; a generation module for determining a target roadside unit based on the request message and generating a first priority passage message based on the request message and the identification information; the sending module is further configured to send the first priority passage message to the target roadside unit, wherein the first priority passage message is used to instruct ordinary vehicles within the signal coverage area of ​​the target roadside unit to give way to the target emergency vehicle after receiving the vehicle information of the target emergency vehicle.

[0008] Thirdly, embodiments of this application provide a computer-readable medium having a computer program stored thereon, which, when executed by a processor, implements the emergency vehicle priority passage method as described in the above technical solutions.

[0009] Fourthly, embodiments of this application provide an electronic device comprising: a processor; and a memory for storing executable instructions of the processor; wherein the processor is configured to execute the emergency vehicle priority passage method as described above by executing the executable instructions.

[0010] Fifthly, embodiments of this application provide a computer program product or computer program that includes computer instructions stored in a computer-readable medium. A processor of an electronic device reads the computer instructions from the computer-readable medium and executes the computer instructions, causing the electronic device to perform the emergency vehicle priority passage method as described in the above technical solutions.

[0011] In the technical solution provided in this application embodiment, the vehicle network server receives a request message sent by the emergency vehicle service platform and reviews it. After the review is passed, the server sends back the identification information corresponding to the target emergency vehicle to the emergency vehicle service platform. Based on the request message, the server determines the target roadside unit and generates a first priority passage message based on the request message and the identification information. This first priority passage message is sent to the target roadside unit. The first priority passage message instructs ordinary vehicles within the signal coverage area of ​​the target roadside unit to give way to the target emergency vehicle upon receiving its vehicle information. The technical solution provided in this application, on the one hand, enables priority passage for emergency vehicles through server review and roadside unit-assisted confirmation, ensuring the priority right-of-way for emergency vehicles; on the other hand, it avoids the inequality of right-of-way caused by emergency vehicles not performing tasks still enjoying priority right-of-way.

[0027] Figure 1 An architectural block diagram of an emergency vehicle priority passage system applying the technical solution of this application is schematically shown.

[0028] like Figure 1 As shown, the emergency vehicle priority passage system 100 may include a target emergency vehicle 101, an emergency vehicle service platform 102, a vehicle network server 103, a target roadside unit 104, ordinary vehicles 105, and a network.

[0029] Among them, the target emergency vehicle 101 can be a vehicle such as a fire truck or ambulance used to perform emergency tasks. It is equipped with a communication module that communicates with the emergency vehicle service platform 102 and an on-board unit (OBU) that communicates with the target roadside unit 104 and ordinary vehicles 105. When it performs a task, it can send a task review request to the emergency vehicle service platform through the communication module on the vehicle and send vehicle information to the target roadside unit 104 and ordinary vehicles through the OBU installed at the front of the vehicle. The vehicle information includes the identification information and vehicle safety information corresponding to the target emergency vehicle.

[0030] The emergency vehicle service platform 102 is used to review the tasks performed by the target emergency vehicle and transmit data with the vehicle network server 103 to obtain the identification information corresponding to the target emergency vehicle. It can transmit data with the target emergency vehicle 101 through networks such as 3G / 4G / 5G. When the target emergency vehicle 101 performs an emergency task, it can send a task review request to the emergency vehicle service platform through the network. The emergency vehicle service platform 102 reviews the information in the task review request. After the review is approved, a request message is formed based on the information in the task review request.

[0031] The vehicle network server 103 can be a cloud server or other types of servers. It is used to receive request messages sent by the emergency vehicle service platform 102 through the network and review them. When the review is approved, the vehicle network server 103 can allocate a reserved identification information to the target emergency vehicle 101 and send the identification information to the emergency vehicle service platform 102. The identification information is the ID that the target emergency vehicle 101 can use when performing the task. Furthermore, the vehicle network server 103 can also generate a first priority passage message based on the information in the request message and the identification information, and send the first priority passage message through the network to the target roadside unit 104 within the driving route range of the target emergency vehicle 101.

[0032] After receiving the first priority passage message, the target roadside unit 104 can parse it to obtain the identification information of the target emergency vehicle. After receiving the vehicle message of the target emergency vehicle, it can form a confirmation message based on the identification information and broadcast it to ordinary vehicles within its signal coverage area.

[0033] Ordinary vehicle 105, i.e. social vehicle, can parse the confirmation message broadcast by the target roadside unit 104 after receiving it to obtain the identification information of the target emergency vehicle. When it receives the vehicle message sent by the target emergency vehicle, it can calculate the distance and time of arrival of the target emergency vehicle based on the vehicle message analysis, and then avoid the target emergency vehicle 101.

[0034] The vehicle-to-everything (V2X) server 103 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The network can be a communication medium of various connection types that can provide communication links between the target emergency vehicle 101 and the emergency vehicle service platform 102, the emergency vehicle service platform 102 and the V2X server 103, the V2X server 103 and the target roadside unit 104, the target roadside unit 104 and the target emergency vehicle 101, and ordinary vehicles 105, such as wired or wireless communication links.

[0035] Depending on the implementation requirements, the system architecture in this application embodiment can have any number of target emergency vehicles 101, vehicle networking server 103, target roadside units 104, ordinary vehicles 105, and a network. For example, the vehicle networking server 103 can be a server group composed of multiple server devices.

[0036] The technical solution of this application relates to the field of vehicle networking technology, specifically to intelligent transportation systems and intelligent vehicle-road cooperative systems.

[0037] Intelligent Traffic Systems (ITS), also known as Intelligent Transportation Systems, effectively integrate advanced science and technology (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations research, artificial intelligence, etc.) into transportation, service control, and vehicle manufacturing. This strengthens the connection between vehicles, roads, and users, thereby forming a comprehensive transportation system that ensures safety, improves efficiency, enhances the environment, and saves energy.

[0038] Intelligent Vehicle Infrastructure Cooperative Systems (IVICS) are a development direction of Intelligent Transportation Systems (ITS). IVICS utilizes advanced wireless communication and next-generation Internet technologies to implement comprehensive, real-time dynamic information exchange between vehicles and infrastructure. Based on the collection and fusion of dynamic traffic information across all times and spaces, it conducts active vehicle safety control and cooperative road management, fully realizing effective collaboration between people, vehicles, and roads. This ensures traffic safety, improves traffic efficiency, and ultimately forms a safe, efficient, and environmentally friendly road traffic system.

[0039] Furthermore, when using cloud servers for data processing in an emergency vehicle priority passage system, this application also relates to cloud technology and cloud applications, specifically involving the Internet of Things and cloud IoT.

[0040] Cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software, and networks within a wide area network or local area network to achieve data computing, storage, processing, and sharing.

[0041] Cloud technology is a collective term for network technologies, information technologies, integration technologies, management platform technologies, and application technologies applied to the cloud computing business model. It can form resource pools, providing flexible and convenient on-demand access. Cloud computing technology will become a crucial support. Backend services of technical network systems require substantial computing and storage resources, such as video websites, image websites, and many portal websites. With the rapid development and application of the internet industry, every item may have its own identification mark in the future, requiring transmission to backend systems for logical processing. Data at different levels will be processed separately, and various industry data will all require robust system support, which can only be achieved through cloud computing.

[0042] The Internet of Things (IoT) refers to the use of various information sensors, RFID technology, GPS, infrared sensors, laser scanners, and other devices and technologies to collect real-time data on any object or process that needs to be connected or interacted with. This data includes information on sound, light, heat, electricity, mechanics, chemistry, biology, location, and other parameters. Through various possible network access methods, it enables ubiquitous connectivity between things and between things and people, achieving intelligent perception, identification, and management of objects and processes. The IoT is an information carrier based on the internet and traditional telecommunications networks, allowing all independently addressable ordinary physical objects to form an interconnected network.

[0043] Cloud IoT aims to connect the information sensed and commands received by traditional IoT devices to the Internet, truly achieving networking. It also enables massive data storage and computation through cloud computing technology. Due to the nature of IoT, which involves connecting things to each other and sensing the current operating status of each "object" in real time, a large amount of data information is generated in this process. How to aggregate this information and how to sift out useful information from the massive amount of data to support decision-making for future development have become key issues affecting the development of IoT. As a result, IoT cloud based on cloud computing and cloud storage technology has become a powerful support for IoT technology and applications.

[0044] In the related technologies of this application, a physical device, such as a button, is usually installed on the vehicle end of an emergency vehicle. When the device is activated, the emergency vehicle will broadcast basic vehicle safety information. When ordinary vehicles receive the basic vehicle safety information sent by the emergency vehicle, they will give way in a timely manner to allow the emergency vehicle to pass first and obtain priority right-of-way.

[0045] Figure 2 The diagram illustrates the interface for ordinary vehicles to yield to emergency vehicles, such as... Figure 2As shown, emergency vehicles and regular vehicles are located in the same lane, with the emergency vehicle behind the regular vehicle. When the emergency vehicle driver sends an emergency vehicle message via a touch device, the regular vehicle can parse the received emergency vehicle message. Once it is confirmed to be an emergency vehicle, the vehicle calculates the time and distance of the emergency vehicle's arrival and changes lanes accordingly to avoid the emergency vehicle in a timely manner.

[0046] However, the relevant technology has its drawbacks. When emergency vehicles are not performing a mission, based on the principle of fairness, they should not have priority on the road and should travel like ordinary vehicles. Furthermore, even if the vehicle ID sent by an emergency vehicle is reviewed to determine its eligibility for priority, since this ID is temporary, it cannot verify whether the vehicle is actually performing a mission, thus making it impossible to determine whether the emergency vehicle is entitled to priority.

[0047] In view of the problems existing in the related technologies, the technical solutions provided in this application, such as the emergency vehicle priority passage method, emergency vehicle priority passage device, computer-readable medium, and electronic device, are described in detail below with reference to specific embodiments.

[0048] Figure 3 The diagram illustrates a flowchart of an emergency vehicle priority passage method according to one embodiment of this application. This emergency vehicle priority passage method can be executed by a vehicle network server, such as... Figure 1 The vehicle networking server 103 in the system. For example... Figure 3 As shown, the emergency vehicle priority passage method in this application embodiment may include:

[0049] S310: Receive a request message sent by the emergency vehicle service platform and review the request message;

[0050] S320: After the review is approved, send the identification information corresponding to the target emergency vehicle to the emergency vehicle service platform;

[0051] S330: Determine the target roadside unit based on the request message, and generate a first priority passage message based on the request message and the identification information;

[0052] S340: Send the first priority passage message to the target roadside unit. The first priority passage message is used to instruct ordinary vehicles within the signal coverage area of ​​the target roadside unit to give way to the target emergency vehicle after receiving the vehicle information of the target emergency vehicle.

[0053] In the emergency vehicle priority passage method provided in this application embodiment, the vehicle network server receives a request message sent by the emergency vehicle service platform and reviews it. After the review is passed, the server sends back the identification information corresponding to the target emergency vehicle to the emergency vehicle service platform. The server determines the target roadside unit based on the request message and generates a first priority passage message based on the request message and the identification information. This first priority passage message is sent to the target roadside unit so that ordinary vehicles within the signal coverage area of ​​the target roadside unit can yield to the target emergency vehicle after receiving the vehicle information sent by the target emergency vehicle. This application, on the one hand, can achieve priority passage for emergency vehicles through vehicle network server review and roadside unit-assisted confirmation, ensuring the priority right-of-way for emergency vehicles; on the other hand, it can avoid the inequality of right-of-way caused by emergency vehicles not performing tasks still enjoying priority right-of-way.

[0054] The following section uses a vehicle network server as an example of a vehicle network cloud platform to explain in detail the specific implementation methods of each step in the emergency vehicle priority passage method.

[0055] In S310, a request message sent by the emergency vehicle service platform is received and the request message is reviewed.

[0056] In one embodiment of this application, the emergency vehicle service platform is a platform for reviewing the missions of emergency vehicles. For different types of emergency vehicles, the emergency vehicle service platform can be a platform specifically set up by the corresponding agency for reviewing emergency vehicles. For example, when the emergency vehicle is a fire truck, the emergency vehicle service platform can be a service platform set up by the fire protection system for reviewing the missions of fire trucks dispatched to the scene; when the emergency vehicle is an ambulance, the emergency vehicle service platform can be a service platform set up by the medical system for reviewing the missions of fire trucks providing emergency medical services.

[0057] In one embodiment of this application, before executing a mission, the target emergency vehicle first determines its driving route and estimated mission time based on the specific mission. Then, based on the driving route and estimated mission time, it generates a mission review request and sends this request to the emergency vehicle service platform for review. After the review is approved, the emergency vehicle service platform generates a request message based on the information in the mission review request and sends this request message to the vehicle-to-everything (V2X) cloud platform for priority right-of-way review.

[0058] Taking ambulance emergency response as an example, after receiving an emergency call, medical personnel send the emergency information to the appropriate ambulance. The ambulance driver can then determine the fastest route from the hospital to the destination based on the location of the person in need, as well as the approximate driving time. After determining the ambulance route and estimated mission time, a mission review request is generated and sent to the hospital's emergency vehicle service platform. The platform reviews the emergency response mission to verify its authenticity, ensuring that the ambulance is indeed performing an emergency task and further guaranteeing the fairness of the ambulance's right-of-way.

[0059] Furthermore, when multiple ambulances are performing emergency rescue missions, each ambulance, after determining its route and estimated mission time, can generate a mission review request based on the route, estimated mission time, and ambulance license plate number. This allows the emergency vehicle service platform to review the mission of each ambulance and accurately send the identification information fed back by the vehicle network cloud platform to the corresponding ambulance.

[0060] In one embodiment of this application, after receiving a request message from the emergency vehicle service platform, the vehicle-to-everything (V2X) cloud platform can review the request message to determine whether the emergency vehicle is eligible for priority right-of-way. Since the emergency vehicle service platform has verified the authenticity of the emergency vehicle's mission, indicating that the target emergency vehicle is indeed applying for priority right-of-way to perform official duties, the V2X cloud platform, after approving the priority right-of-way for the target emergency vehicle, can then send the reserved identification information back to the emergency vehicle service platform, so that the emergency vehicle service platform can then pass this identification information back to the target emergency vehicle.

[0061] In S320, after the review is approved, the identification information corresponding to the target emergency vehicle is sent to the emergency vehicle service platform.

[0062] In one embodiment of this application, after the information in the request message is approved, the identification information can be sent to the emergency vehicle service platform, and the identification information can be fed back to the target emergency vehicle through the emergency vehicle service platform to ensure that the target emergency vehicle can enjoy the right-of-way during the driving process.

[0063] In one embodiment of this application, the identification information assigned to the target emergency vehicle is reserved for emergency vehicles by the vehicle-to-everything (V2X) cloud platform and cannot be used by ordinary vehicles. The identification information for emergency vehicles can have the same composition as that for ordinary vehicles, distinguished only by the number of digits. For example, ordinary vehicles use identification information ending in 1-8, while emergency vehicles use identification information ending in 9 or 0. Of course, the composition of the identification information for emergency vehicles can also differ from that of ordinary vehicles. When an ordinary vehicle receives identification information with a structure different from its own, it automatically identifies the vehicle corresponding to that identification information as an emergency vehicle performing a mission.

[0064] In S330, the target roadside unit is determined according to the request message, and a first priority passage message is generated according to the request message and the identification information.

[0065] In one embodiment of this application, intelligent transportation in a vehicle-to-everything (V2X) scenario is mainly achieved through vehicle-road cooperation and vehicle-to-vehicle cooperation. The implementation of V2X and vehicle-to-vehicle cooperation is primarily based on the collaboration between roadside units (RSUs), onboard units (OBUs), and V2X nodes. The roadside units, onboard units, and V2X nodes can transmit data via radio waves. The vehicle's onboard unit (OBU) can receive information sent by the roadside units (RSUs) on the corresponding road segment, vehicle information sent by the onboard units (OBUs) of other vehicles within its receiving range, and vehicle information sent by its own V2X node. The OBU then sends the received information from the roadside units (RSUs) and the vehicle information from the onboard units (OBUs) of other vehicles to its own V2X node, so that the V2X node can send the received information to the computing unit for data processing. Simultaneously, the vehicle's own information can also be sent to other vehicles through data transmission between onboard units, thereby realizing vehicle-to-vehicle cooperation and vehicle-road cooperation. Therefore, in order to ensure that the target emergency vehicle can complete its mission smoothly and enjoy priority right-of-way, it is necessary to send the target emergency vehicle's information to all ordinary vehicles within the driving route range through the roadside unit, so that ordinary vehicles can give way in time after receiving the vehicle information sent by the emergency vehicle.

[0066] In one embodiment of this application, the request message sent by the emergency vehicle service platform includes the driving route and estimated time of the emergency vehicle when performing the task. Based on the driving route of the emergency vehicle, all roadside units included in the route range can be determined, and these roadside units can be used as target roadside units.

[0067] In one embodiment of this application, after determining the target roadside unit, a first priority passage message can be formed based on the expected execution time and assigned identification information of the target emergency vehicle. This first priority passage message is then sent to the target roadside unit, allowing the target roadside unit to broadcast the first priority passage message corresponding to the target emergency vehicle to ordinary vehicles within its signal coverage area. For example, the first priority passage message could be something like, "The emergency vehicle with vehicle ID 27869 is expected to pass between 12:00 and 13:00," etc.

[0068] Furthermore, the first priority passage message can also be generated in other ways. When the route includes multiple road segments, the time periods during which the target emergency vehicle passes through different road segments can be calculated based on the departure time and speed of the target emergency vehicle, and then the corresponding first priority passage message for each road segment can be generated based on the different time periods. For example, if an ambulance departs at 12:00 to perform an emergency rescue mission, traveling at a constant speed of v, and its route includes road segment A (length S1), road segment B (length S2), and road segment C (length S3), calculations show that the ambulance will pass through road segment A from 12:00 to 12:30, through road segment B from 12:31 to 12:40, and through road segment C from 12:41 to 13:00. Therefore, the following first-priority passage messages can be generated: "Emergency vehicle with vehicle ID 27869 is expected to pass through road segment A between 12:00 and 12:30," "Emergency vehicle with vehicle ID 27869 is expected to pass through road segment B between 12:31 and 12:40," and "Emergency vehicle with vehicle ID 27869 is expected to pass through road segment C between 12:41 and 13:00."

[0069] It is worth noting that the above embodiments are based on the speed of constant travel. However, the vehicle does not necessarily maintain a constant speed during travel. Therefore, the calculation can be performed based on the average speed, maximum speed, and minimum speed of the target emergency vehicle when performing the task, in order to determine the time period of passing through each road segment.

[0070] In S340, the first priority passage message is sent to the target roadside unit. The first priority passage message is used to instruct ordinary vehicles within the signal coverage area of ​​the target roadside unit to give way to the target emergency vehicle after receiving the vehicle information of the target emergency vehicle.

[0071] In one embodiment of this application, after forming a first priority passage message, the first priority passage message can be sent to a target roadside unit so that the target roadside unit can promptly identify the vehicle with the identification information upon receiving the first priority passage message, and then form a confirmation message based on the identification information of the target emergency vehicle, and broadcast it in advance to ordinary vehicles within the signal coverage area to give way to the target emergency vehicle. Accordingly, after forming first priority passage messages corresponding to each road segment, each first priority passage message can be sent to the target roadside unit corresponding to each road segment. Taking the driving route in the above embodiment as including road segments A, B, and C as an example, after obtaining the first priority passage message, the first priority passage message can be sent to the target roadside units corresponding to road segments A, B, and C respectively, so that each target roadside unit can broadcast to ordinary vehicles within the signal coverage area after receiving the vehicle message of the target emergency vehicle.

[0072] In one embodiment of this application, the message broadcast by the target roadside unit to ordinary vehicles within its signal coverage area is a confirmation message, which confirms that the target emergency vehicle has entered the signal coverage area of ​​the target roadside unit.

[0073] Figure 4 A flowchart illustrating the broadcast confirmation message from the target roadside unit is shown, as follows: Figure 4 As shown, in S401, after receiving the first priority passage message, the first priority passage message is parsed to obtain the identification information corresponding to the target emergency vehicle; in S402, the first vehicle to be identified information is received and parsed to obtain the first identification information; in S403, the first identification information is compared with the identification information corresponding to the target emergency vehicle; in S404, when the first identification information is the same as the identification information corresponding to the target emergency vehicle, a confirmation message is generated based on the identification information; in S405, the confirmation message is broadcast to ordinary vehicles within the signal coverage area.

[0074] In S402, the first vehicle information to be identified is vehicle information sent by a vehicle traveling on the road to the target roadside unit through the on-board unit (OBU). This information includes the vehicle's identification information and vehicle safety information. After obtaining the vehicle's identification information, the target roadside unit can compare it with the identification information of the target emergency vehicle. In S404, when the first identification information to be identified is the same as the identification information of the target emergency vehicle, it can be determined that the vehicle sending the vehicle information is the target emergency vehicle. Then, a confirmation message can be generated based on the identification information of the target emergency vehicle and broadcast to ordinary vehicles within the signal coverage area. When the first identification information to be identified is different from the identification information of the target emergency vehicle, it means that the vehicle sending the vehicle information is not the target emergency vehicle, and there is no need to broadcast to ordinary vehicles within the signal coverage area.

[0075] In one embodiment of this application, after the target roadside broadcasts the confirmation information to ordinary vehicles within the signal coverage area, the ordinary vehicles can parse the identification information of the target emergency vehicle from the confirmation information. Then, after receiving vehicle information sent by other vehicles' OBUs, the ordinary vehicles can determine whether the target emergency vehicle is behind them based on the identification information in the vehicle information and the identification information of the target emergency vehicle, so as to avoid it in time.

[0076] By sending a confirmation message containing the identification information of the target emergency vehicle to ordinary vehicles within the signal coverage area through the target roadside unit, the target emergency vehicle can be confirmed, ensuring that the emergency vehicle that ordinary vehicles give way to is an emergency vehicle that reasonably enjoys the right-of-way, thus guaranteeing the fairness of the right-of-way.

[0077] Figure 5 The diagram illustrates the process of a regular vehicle yielding to a target emergency vehicle. Figure 5 As shown, in S501, the confirmation message is parsed to obtain the identification information corresponding to the target emergency vehicle; in S502, the second vehicle information to be identified is received and parsed to obtain the second identification information and vehicle safety information; in S503, the second identification information to be identified is compared with the identification information corresponding to the target emergency vehicle; in S504, when the second identification information to be identified is the same as the identification information corresponding to the target emergency vehicle, avoidance information is determined according to the vehicle safety information, and the target emergency vehicle is avoided according to the avoidance information.

[0078] In S502, the composition of the second vehicle information to be identified is the same as that of the first vehicle information to be identified in S402, including the vehicle identification information and vehicle safety information. In S504, when the second identification information to be identified is the same as the identification information of the target emergency vehicle, it means that the target emergency vehicle is behind the ordinary vehicle, and the ordinary vehicle needs to give way to the target emergency vehicle according to its driving parameters and the road conditions of the road.

[0079] In one embodiment of this application, a computing unit is provided in an ordinary vehicle. This computing unit can determine avoidance information based on the vehicle safety information of the target emergency vehicle, specifically the arrival time and distance of the target emergency vehicle. After determining the arrival time and distance of the target emergency vehicle, this information can be fed back to the driver of the ordinary vehicle through a human-machine interface (HMI), so that the driver can avoid the target emergency vehicle by changing lanes when it approaches, based on the calculated time and distance. The HMI can be the vehicle's built-in central control screen or the driver's smartphone or other device, as long as it can connect to the vehicle's computing unit and receive and display the avoidance information fed back by the computing unit.

[0080] In one embodiment of this application, the arrival time and distance of the target emergency vehicle can be calculated based on parameters such as the speed and position of the target emergency vehicle and ordinary vehicles. Table 1 shows the parameters included in the vehicle safety information, as detailed below:

[0081] Table 1 Vehicle Safety Information

[0082]

[0083]

[0084] When a regular vehicle is an autonomous vehicle, the autonomous driving computing platform connected to the autonomous vehicle can calculate the arrival time and distance of the target emergency vehicle based on the vehicle safety information of the target emergency vehicle and the current driving parameters of the autonomous vehicle. Based on the arrival time and distance of the target emergency vehicle, avoidance information can be generated. Then, the autonomous driving computing platform can send the avoidance information to the autonomous driving control system so that the autonomous driving control system can control the autonomous vehicle to avoid the target emergency vehicle based on the avoidance information.

[0085] In one embodiment of this application, only after a regular vehicle receives a confirmation message broadcast by the target roadside unit and then receives vehicle information sent by the target emergency vehicle will it determine avoidance information based on the target emergency vehicle's safety information and avoid the target emergency vehicle according to the avoidance information, thus ensuring that the target emergency vehicle enjoys priority right-of-way. If a regular vehicle receives vehicle information sent by the target emergency vehicle but does not receive a confirmation message broadcast by the target roadside unit, even if the regular vehicle can parse the received vehicle information to obtain the corresponding identification information and determine from the composition of the identification information that the vehicle may be the target emergency vehicle, the regular vehicle will not initiate the avoidance information calculation process and avoid the target emergency vehicle. Only the identification information of the target emergency vehicle issued through cloud platform review and roadside unit assisted confirmation is the identification information of an emergency vehicle that reasonably enjoys priority right-of-way. This fully guarantees the fairness of right-of-way and prevents the abuse of priority right-of-way.

[0086] In one embodiment of this application, after obtaining identification information, the target emergency vehicle may change its driving route and / or expected mission time. In this case, the target emergency vehicle needs to send the changed driving route and / or expected mission time to the emergency vehicle service platform and the vehicle network cloud platform for review. The vehicle network cloud platform can then modify the target roadside unit and the first priority passage message according to the changed driving route and / or expected mission time to obtain the target changed roadside unit and the second priority passage message, and send the second priority communication message to the target changed roadside unit.

[0087] Figure 6 The diagram illustrates the process of obtaining priority right-of-way when the mission information of a target emergency vehicle changes. Figure 6 As shown, the process may include:

[0088] In S601, the system receives task change information corresponding to the target emergency vehicle sent by the emergency vehicle service platform, and reviews the task change information.

[0089] In one embodiment of this application, when the target emergency vehicle's route or estimated mission time changes, it can send the changed route and / or estimated mission time to the emergency vehicle service platform for review. Upon approval, the emergency vehicle service platform can generate mission change information based on the identification information corresponding to the target emergency vehicle and the changed route and / or estimated mission time, and then send this mission change information to the vehicle-to-everything (V2X) cloud platform. After receiving the mission change information, the V2X cloud platform can review it and execute the target operation based on the review results.

[0090] In S602, after the review is approved, a task change confirmation message is sent to the emergency vehicle service platform.

[0091] In one embodiment of this application, after the vehicle network cloud platform approves the task change information, it can send task change confirmation information to the emergency vehicle business platform, and at the same time store the changed target emergency vehicle's driving route and / or the expected task execution time with the corresponding identification information.

[0092] In S603, the target roadside unit is determined based on the task change information, and a second priority passage message is formed based on the task change information and the identification information.

[0093] In one embodiment of this application, after sending task change confirmation information to the emergency vehicle service platform, the vehicle network cloud platform can determine the target updated roadside unit based on the task change information, and form a second priority passage message based on the task change information and the identification information corresponding to the target emergency vehicle.

[0094] In one embodiment of this application, the task change information includes, in addition to the identification information corresponding to the target emergency vehicle, the changed driving route and the initial estimated task execution time, the changed driving route and the changed estimated task execution time, and the initial driving route and the changed estimated task execution time. When the driving route is determined to be a changed driving route, the target updated roadside unit is re-determined based on the roadside units included in the changed driving route. When the driving route is determined to be the initial driving route, the initial target roadside unit is used as the target updated roadside unit. Accordingly, when forming the second priority passage message, if the estimated task execution time in the task change information has not changed, the second priority passage message is formed based on the initial estimated task execution time and the identification information of the target emergency vehicle. If the estimated task execution time in the task change information has changed, the second priority passage message is formed based on the changed estimated task execution time and the identification information corresponding to the target emergency vehicle.

[0095] In S604, the second priority passage message is sent to the target updated roadside unit. The second priority passage message is used to instruct ordinary vehicles within the signal coverage area of ​​the target updated roadside unit to give way to the target emergency vehicle after receiving the vehicle information of the target emergency vehicle.

[0096] In one embodiment of this application, after determining the target roadside unit and forming a second priority passage message, the second priority passage message can be sent to the target roadside unit so that the target roadside unit can generate a confirmation update message after obtaining the vehicle message of the target emergency vehicle, and broadcast the confirmation update message to ordinary vehicles within the signal coverage area so that ordinary vehicles can give way to the target emergency vehicle after receiving the vehicle message of the target emergency vehicle.

[0097] and Figure 4 The process for broadcasting confirmation messages to the target roadside unit is similar to that shown; the process for broadcasting confirmation update messages to the target roadside unit is as follows. Figure 7 As shown, in S701, the second priority passage message is parsed by the target update roadside unit to obtain the identification information corresponding to the target emergency vehicle; in S702, third vehicle information to be identified is received and parsed to obtain third identification information; in S703, the third identification information to be identified is compared with the identification information corresponding to the target emergency vehicle; in S704, when the third identification information to be identified is the same as the identification information corresponding to the target emergency vehicle, a confirmation update message is generated based on the identification information; in S705, the confirmation update message is broadcast to ordinary vehicles within the signal coverage area.

[0098] For example, when a fire truck responds to an emergency, it first determines its route and estimated mission time based on the emergency location. After verification by the emergency vehicle service platform and the vehicle-to-everything (V2X) cloud platform, it obtains the corresponding identification information. However, if the fire truck needs to temporarily change its route during the journey, the driver of the fire truck needs to log in to the emergency vehicle service platform and submit the revised route and estimated mission time. After the emergency vehicle service platform approves the changes, it generates mission change information based on the fire truck's identification information, the revised route, and the estimated mission time. This information is then sent to the V2X cloud platform to update the fire truck's right-of-way priority information. Once the V2X cloud platform approves the changes, it corrects the fire truck's initial route and estimated mission time to the revised route and estimated mission time, and sends confirmation of the change back to the emergency vehicle service platform. Simultaneously, it determines the target roadside unit based on the revised route, generates a second priority passage message based on the fire truck's identification information and the revised estimated mission time, and sends this second priority passage message to the target roadside unit. After receiving the vehicle information sent by the fire truck, the target update roadside unit can generate a confirmation update message based on the police car's identification information and broadcast the confirmation update message to ordinary vehicles within the signal coverage area. This allows ordinary vehicles to give way to the fire truck after receiving the vehicle information sent by the fire truck containing the identification information, thus ensuring the fire truck's right-of-way.

[0099] In one embodiment of this application, after the vehicle-to-everything (V2X) cloud platform approves the task change information, it can also assign updated identification information to the target emergency vehicle. Simultaneously, the V2X cloud platform sends the updated identification information to the emergency vehicle service platform while sending the task change confirmation information, so that the emergency vehicle service platform can send the updated identification information to the target emergency vehicle. At the same time, the V2X cloud platform forms third priority passage information based on the expected task execution time and the updated identification information in the task change information, and sends this third priority passage information to the target updated roadside unit. This third priority passage information instructs the target updated roadside unit to generate a confirmation update message containing the updated identification information after receiving vehicle information from the target emergency vehicle, and then sends this confirmation update message to ordinary vehicles within the signal coverage area, so that ordinary vehicles can give way to the emergency vehicle upon receiving vehicle information with the updated identification information.

[0100] To make the technical solution of this application clearer, the following explanation will take the ambulance performing emergency rescue missions as an example.

[0101] Figure 8 The diagram shows the interactive flowchart of an ambulance performing an emergency rescue mission, such as... Figure 8As shown, in S801, after receiving an emergency call, the ambulance driver determines the route and estimated time of execution based on the location of the person in need, and generates a task review request based on the route and estimated time. In S802, the driver connects to the emergency vehicle service platform via the network and sends the task review request to the platform. In S803, the emergency vehicle service platform reviews the information in the task review request. In S804, after the review is approved, a request message is generated based on the ambulance's route and estimated time, and the request message is sent to the vehicle network cloud platform. In S805, the vehicle-to-everything (V2X) cloud platform reviews the request message; in S806, after approval, it sends the identification information corresponding to the ambulance to the emergency vehicle service platform; in S807, the emergency vehicle service platform sends the identification information to the ambulance; in S808, the V2X cloud platform determines all roadside units within the driving route range based on the driving route in the request message, and uses all roadside units as target roadside units, forming a first priority passage message based on the ambulance's identification information and the estimated execution time of the ambulance's mission; in S809, the first priority passage message... The message is sent to the target roadside unit; in S810, the target roadside unit parses the first priority passage message to obtain the ambulance's identification information and estimated mission execution time; in S811, the target roadside unit receives vehicle information sent by vehicles within the signal coverage area; in S812, the vehicle information is parsed to obtain the first identification information to be identified; in S813, the first identification information to be identified is compared with the ambulance's identification information, and when the first identification information to be identified is the same as the ambulance's identification information, a confirmation message is formed based on the ambulance's identification information; in S814, the confirmation message is sent to the target roadside unit. The message is broadcast to ordinary vehicles within the signal coverage area; in S815, ordinary vehicles parse the confirmation message to obtain the ambulance's identification information; in S816, ordinary vehicles receive vehicle messages sent by other vehicles; in S817, the vehicle messages are parsed to obtain second identification information; in S818, the second identification information is compared with the ambulance's identification information, and when the second identification information matches the ambulance's identification information, avoidance information is determined based on the ambulance's vehicle safety information and the vehicle's driving parameters; in S819, the ambulance is avoided based on the avoidance information.

[0102] Furthermore, Figure 9 The diagram illustrates the interactive process by which an ambulance, after receiving identification information, changes its route and / or its estimated mission time to obtain priority right-of-way. Figure 9As shown, in S901, the ambulance generates a mission change review request based on the changed driving route and / or the estimated mission time; in S902, the mission change review request is sent to the emergency vehicle service platform; in S903, the emergency vehicle service platform reviews the information in the mission change review request; in S904, after the review is approved, mission change information is generated based on the ambulance's identification information and the changed driving route and / or the estimated mission time; in S905, the mission change information is sent to the vehicle network cloud platform for review. In S906, after approval, a task change confirmation message is sent to the emergency vehicle service platform; in S907, the emergency vehicle service platform sends the task change confirmation message back to the ambulance; in S908, the vehicle-to-everything (V2X) cloud platform determines the target roadside unit based on the driving route in the task change message, and simultaneously generates second priority driving information based on the ambulance's identification information and the estimated task execution time in the task change message; in S909, the second priority driving information is sent to the target roadside unit; in S910, the target roadside unit parses the information. The second priority passage message obtains the ambulance's identification information and estimated mission time; in S911, the target roadside unit receives vehicle information sent by vehicles within the signal coverage area; in S912, the vehicle information is parsed to obtain the third identification information to be identified, and the third identification information to be identified is compared with the ambulance's identification information; in S913, when the vehicle identification information matches the ambulance's identification information, a confirmation update message is generated based on the ambulance's identification information; in S914, the confirmation update message is sent to ordinary vehicles within the signal coverage area. In S915, a regular vehicle parses the confirmation message to obtain the ambulance's identification information; in S916, a regular vehicle receives vehicle messages sent by other vehicles; in S917, the vehicle messages are parsed to obtain the fourth identification information to be identified; in S918, the fourth identification information to be identified is compared with the ambulance's identification information, and when the fourth identification information to be identified is the same as the ambulance's identification information, avoidance information is determined based on the ambulance's vehicle safety information and the vehicle's driving parameters; in S919, avoidance is performed on the ambulance based on the avoidance information.

[0103] In S906, when the vehicle-to-everything (V2X) cloud platform sends confirmation information to the emergency vehicle service platform, it can also reassign updated identification information to ambulances and send this updated information to the emergency vehicle service platform. The emergency vehicle service platform can then relay this updated identification information back to the ambulance, allowing it to communicate with target roadside units and other vehicles to obtain priority right-of-way. Correspondingly, in S907-S919, all identification information related to ambulances is updated identification information. This prevents other vehicles from illegally obtaining ambulance identification information, which could prevent target roadside units and other vehicles from accurately identifying ambulances performing emergency rescue missions, thus depriving ambulances of priority right-of-way and delaying treatment of rescue personnel.

[0104] The emergency vehicle priority passage method in this application involves receiving and reviewing request messages from an emergency vehicle service platform via a vehicle-to-everything (V2X) server. Upon successful review, the server sends back the identification information corresponding to the target emergency vehicle to the emergency vehicle service platform. Simultaneously, it identifies the target roadside unit based on the information in the request message and generates a first priority passage message based on the request message and identification information. This first priority passage message is then sent to the target roadside unit, enabling ordinary vehicles within the target roadside unit's signal coverage area to yield to the target emergency vehicle upon receiving its information. This application, on the one hand, ensures priority passage for emergency vehicles through server review and roadside unit-assisted confirmation, guaranteeing their right-of-way; on the other hand, it avoids the inequality of right-of-way caused by emergency vehicles not performing duties still enjoying priority.
