[0002] In related technologies, in the traditional highway traffic management system, the emergency lane is a passage specifically provided for emergency vehicles or vehicles in special circumstances.

[0003] However, in actual operation, emergency lanes are often occupied by parked vehicles, especially when there is traffic congestion on the main lanes. Some drivers enter the emergency lane to avoid congestion, causing the dedicated lane to be occupied and thus losing its due emergency function. When an emergency occurs, a traffic accident occurs, or a special vehicle needs to pass quickly, if the emergency lane is occupied, it will greatly affect the efficiency of emergency response, cause delays in rescue, and may even cause more serious secondary accidents.

Detailed Implementation

[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figures 1-11 This invention describes a vehicle-road-cloud-based highway emergency passage system according to an embodiment of the present invention.

[0027] like Figure 1 The diagram shown is a structural schematic of a highway emergency passage system based on vehicle-road-cloud according to an embodiment of the present invention. The highway emergency passage system 100 based on vehicle-road-cloud includes: a first image acquisition module 110, a lidar module 120, an edge computing unit 130, a second image acquisition module 140, a vehicle controller 150, a communication module 160, a cloud platform 170, and a roadside controller 180.

[0028] The system includes a first image acquisition module 110 located on one or both sides of the highway, used to acquire information about a first vehicle traveling in front of the vehicle on the highway; a lidar module 120 located on one or both sides of the highway, used to acquire information about a second vehicle traveling in front of the vehicle on the highway; an edge computing unit 130 used to determine the road traffic status within a first preset distance range in front of the vehicle based on the first and second vehicle information, and transmit the road traffic status to the cloud platform 170 via a communication module 160; a second image acquisition module 140 used to acquire information about the occupancy status of the emergency lane on the highway, and transmit the occupancy status information to the cloud platform 160 via a communication module 160; a vehicle controller 150 used to acquire emergency driving request signals; and a communication module 120. The edge computing unit 130 is used to realize data transmission between the cloud platform 160, the vehicle controller 150, the second image acquisition module 120, and the roadside controller 180; the cloud platform 170 is used to send control commands for instructing the adjustment of the protective unit shape to the roadside controller 180 through the communication module 160 when it receives an emergency driving request signal and determines that the vehicle meets the preset emergency passage conditions based on the road traffic status and lane occupancy information; the roadside controller 180 is used to receive the control commands and send drive commands to the protective unit according to the control commands to adjust the shape of the protective unit, thereby forming an emergency passage area for the vehicle at the target location. The protective unit is set on one or both sides of the highway and is configured to be adjustable in shape to meet the emergency passage needs of the vehicle.

[0029] In the embodiments, combined with Figure 1 and Figure 2 As shown, the first image acquisition module 110 and the lidar module 120 are respectively installed on top of poles on one or both sides of the highway to collect information about vehicles traveling in front of the vehicle. The first image acquisition module 110, for example, uses a high-definition vision sensor and is positioned on top of the highway poles to acquire the number of vehicles ahead and their speed in real time. The lidar module 120, for example, uses a 256-line solid-state lidar sensor to collect point cloud data of the vehicles ahead and their centroid motion speed. Then, the first vehicle information collected by the first image acquisition module 110 and the second vehicle information collected by the lidar module 120 are synchronously transmitted to the edge computing unit 130. The edge computing unit 130 determines the road traffic status within a first preset distance range ahead of the vehicle based on the first and second vehicle information to determine whether traffic congestion has occurred ahead of the vehicle, and transmits the road traffic status to the cloud platform 170 via the communication module 160.

[0030] The second image acquisition module 140 monitors the occupancy status of the emergency lane and uploads this information to the cloud platform 170. When the vehicle controller 150 receives an emergency driving request signal, the cloud platform 170 combines road traffic conditions and lane occupancy information to determine whether preset emergency passage conditions are met. If the preset emergency passage conditions are met, the cloud platform 170 sends a control command to the roadside controller 180 via the communication module 160. The roadside controller 180 then drives the protective unit to adjust its shape according to the control command, forming an emergency passage area at a target location on one or both sides of the highway. This allows vehicles to pass through the emergency passage area, thus solving the emergency passage needs when highway traffic is congested and the emergency lane is occupied, improving highway travel efficiency, and ultimately addressing the emergency travel needs.

[0031] The protective unit is an adjustable structure that can dynamically adapt to emergency passage needs in different scenarios, thereby ensuring the efficiency and safety of vehicles in congested traffic environments.

[0032] Thus, in the aforementioned vehicle-road-cloud-based highway emergency passage system 100, the first image acquisition module 110 and the lidar module 120 respectively acquire information about a first vehicle and a second vehicle traveling in front of the vehicle on the highway, and transmit the first and second vehicle information to the edge computing unit 130. The edge computing unit 130 determines the road traffic status within a first preset distance range in front of the vehicle based on the first and second vehicle information, and transmits the road traffic status to the cloud platform 170 through the communication module 160. At the same time, the second image acquisition module 140 acquires the occupancy status information of the emergency lane, and the vehicle controller 150 acquires the emergency driving request signal. The vehicle controller 150 transmits the occupancy status information and the emergency driving request signal to the cloud platform 170 through the communication module 160, respectively. The cloud platform 170 combines the road traffic status and lane occupancy information to determine whether the preset emergency passage conditions are met. If the preset emergency passage conditions are met, the cloud platform 170 sends a control command to the roadside controller 180 through the communication module 160. The roadside controller 180 drives the protection unit to adjust its shape according to the control command, forming an emergency passage area at the target location on one or both sides of the highway, allowing vehicles to pass through the emergency passage area. This solves the emergency passage needs when highway traffic is congested and the emergency lane is occupied, improves highway travel efficiency, and thus solves the problem of emergency travel needs.

[0033] In one embodiment of the present invention, combined with Figure 2 and Figure 3As shown, the protective unit includes: a drive motor, a telescopic guardrail, a movable guardrail, a guardrail guide rail, a guardrail latch, and guardrail connecting wires; the movable guardrail is mounted on the telescopic guardrail; the drive motor is connected to both the roadside controller and the telescopic guardrail, and upon receiving a drive command, controls the telescopic guardrail to switch states and drives the movable guardrail to move horizontally along the movable guide rail; the guardrail guide rail is located on one side of the telescopic guardrail and guides the movable guardrail to move horizontally along the guide rail; the guardrail latch is located between the tops of two adjacent telescopic guardrails and is used to lock and unlock according to drive commands to achieve the shape transformation of the telescopic guardrail within the target road section and its preset length range; the guardrail connecting wires connect two adjacent telescopic guardrails and provide tensile support and structural fixation for the telescopic guardrails.

[0034] In this embodiment, the drive motor is connected to the roadside controller 180 and the telescopic barrier. After receiving the drive command from the roadside controller 180, the drive motor performs a state switching operation on the telescopic barrier and drives the movable barrier to move along the guide rail, thereby realizing the rapid deployment of the emergency passage area.

[0035] For example, a 10-centimeter-wide telescopic guardrail can rotate from a vertical to a horizontal position under the action of a drive motor, and extend outward by 3.5 meters to expand the emergency lane. A movable guardrail is installed above the telescopic guardrail. After the telescopic guardrail completes its deployment, it moves evenly and synchronously along a guardrail guide rail located on one side of the telescopic guardrail, driven by a drive motor, forming a temporary mesh-like passage structure to provide a stable and safe driving surface for vehicles. To ensure the structural stability and synchronous movement of the telescopic guardrails, the tops of adjacent telescopic guardrails are connected by guardrail latches. These latches lock or unlock according to control commands, allowing multiple telescopic guardrails within a preset length range before and after the target road section to move collaboratively when a change in configuration is needed, completing the overall structural transformation.

[0036] In addition, the protective unit also includes railing cables for providing tensile support and structural fixation, which may be, for example, constructed of high-strength steel wire. Figure 4 As shown, the length of the line connecting the railings can be calculated using the formula, i.e., a = ( ) 1 / 2 .

[0037] Where a is the line length of the connecting rod; H is the installation height of the telescopic guardrail in the vertical state; and d is the lateral distance the telescopic guardrail extends outward in the horizontal state, for example, 3.5 meters.

[0038] To ensure that the guardrail connection line is taut when fully extended, this provides additional tension support to the entire extension structure, enhancing its structural rigidity and stability. Through the coordinated operation of these components, the protection unit can respond rapidly upon receiving a drive command, dynamically adjusting its shape to create a temporary emergency passage zone at a specific location on the highway, significantly improving vehicle traffic efficiency and safety in emergency situations.

[0039] In one embodiment of the present invention, when determining the road traffic state within a first preset distance range ahead of the vehicle based on the first vehicle information and the second vehicle information, the edge computing unit 130 is configured to: determine the number of vehicles and the average speed of the vehicles ahead within the first preset distance range ahead of the vehicle based on the first vehicle information and the second vehicle information, wherein the average speed is the average speed of all vehicles within the first preset distance range; when the number of vehicles is greater than or equal to a preset number threshold and the average speed is less than or equal to a preset speed threshold, the road traffic state is determined to be congested; when the number of vehicles is less than the preset number threshold and / or the average speed is greater than the preset speed threshold, the road traffic state is determined to be unobstructed.

[0040] In this embodiment, when the edge computing unit 130 receives the first image information and the second image information, it extracts the number of vehicles traveling ahead of the current vehicle and the average speed of all vehicles ahead, wherein the average speed is the average speed of all detected vehicles within a first preset distance range. Subsequently, the edge computing unit 130 compares the number of vehicles with a preset number threshold and the average speed with a preset speed threshold to comprehensively determine the current road traffic state.

[0041] If the number of detected vehicles is greater than or equal to a preset number threshold, and the average speed is less than or equal to a preset speed threshold, for example, the first preset range is a range of 100 meters in front of the vehicle, the preset number threshold is, for example, 10, and the average speed is 10 kph. That is, if the number of vehicles in front of the vehicle is greater than or equal to 10 within 100 meters in front of the vehicle, and the average speed of the vehicles in front is greater than or equal to 10 kph, then the road segment is determined to be in a state of traffic congestion; if the number of vehicles in front of the vehicle is less than 10 within 100 meters in front of the vehicle, and / or the average speed of the vehicles in front is greater than 10 kph, then the road is determined to be in a state of smooth traffic. In this way, the road traffic condition can be accurately judged, and the travel efficiency of vehicles on the highway can be improved.

[0042] In one embodiment of the present invention, when it is determined that the vehicle meets the preset emergency passage conditions based on road traffic conditions and lane occupancy information, the cloud platform 170 sends a control command for instructing the adjustment of the protective unit form to the roadside controller 180 through the communication module 160. When the road traffic condition is congested and the emergency lane is occupied, if it is determined that the vehicle meets the preset emergency passage conditions, the cloud platform 170 sends a control command to the roadside controller 180 through the communication module 160.

[0043] In this embodiment, when the edge computing unit 130 determines that the road traffic condition within a first preset distance range ahead of the vehicle is congested, and simultaneously detects that the emergency lane is occupied (e.g., a vehicle is illegally parked or driving), the cloud platform 170 confirms that the vehicle meets the preset emergency passage conditions under the current circumstances. Based on this, the cloud platform 170 sends a control command via the communication module 160 to the roadside controller 180 to instruct the protection unit to adjust its shape, dynamically adjusting the structural form of the protection unit to form a safe and unobstructed temporary emergency passage path at the target location, thereby ensuring the vehicle's efficient and safe passage in congested traffic environments.

[0044] In one embodiment of the present invention, the vehicle controller 150 is further configured to: acquire the length information of the vehicle and transmit it to the cloud platform 170 via the communication module 160.

[0045] In this embodiment, the vehicle controller 150 is not only used to receive and process emergency driving request signals, but also to acquire the length information of the vehicle and transmit this information to the cloud platform 170 via the communication module 160. Upon receiving the length information, the cloud platform 170 will combine the actual length of the vehicle, the current road traffic conditions, and the occupancy status of the emergency lane to comprehensively determine and accurately plan the target location and length range of the emergency passage area, ensuring that the formed emergency passage can meet the vehicle's passage needs without interfering with the surrounding traffic environment.

[0046] In one embodiment of the present invention, when the roadside controller 180 controls the protective unit to perform a shape adjustment action according to the control command, the roadside controller 180 is used to: determine the area where the emergency lane is occupied and the target protective unit within a second preset distance range before and after it, wherein the second preset distance range is determined based on length information; send a drive command to the drive motor according to the control command to start the drive motor, so that the drive motor controls the target telescopic barrier in the target protective unit to rotate from a vertical state to a horizontal state, and controls the target telescopic barrier to extend a preset width along the target direction, while controlling the target movable barrier in the target protective unit to move flat along the guide rail direction to form an emergency passage area.

[0047] The length of the vehicle is denoted as L, and the second preset distance range is the area of ​​length L in front of and behind the vehicle.

[0048] In this embodiment, when the roadside controller 180 receives a control command from the cloud platform 170 to adjust the shape of the protective unit, it first determines the target protective unit that needs to be adjusted in shape based on the vehicle length information obtained from the cloud platform 170 and the specific location where the emergency lane is occupied. Figure 5 As shown, these target protection units include the area where the emergency lane is occupied and all protection units within a second preset distance range before and after it. The second preset distance is determined based on the vehicle length to ensure that the formed emergency passage area can completely cover the vehicle's passage needs.

[0049] After the target protection unit is determined, the roadside controller 180 sends specific drive commands to the drive motors in each target protection unit according to the control commands, and starts the drive motors, such as... Figure 6 As shown, the drive motor rotates the target telescopic barrier from its initial vertical position to a horizontal position; subsequently, as... Figure 7 , Figure 8 and Figure 9 As shown, the telescopic barrier extends a preset width along a set target direction, for example, extending outward by 3.5 meters, to achieve lateral expansion of the emergency lane; simultaneously, as... Figure 10 As shown, the target movable guardrail, arranged on the telescopic guardrail, moves evenly along the guardrail guide rail under the drive of the drive motor. Together with the telescopic guardrail, it forms a continuous, stable, and sufficiently load-bearing temporary mesh emergency passage area. This provides a safe and unobstructed emergency passage path for the vehicle without affecting surrounding traffic, achieving high efficiency and reliability in emergency response. This solves the emergency passage needs when highway traffic is congested and the emergency lane is occupied, improves highway travel efficiency, and ultimately addresses the issue of emergency travel needs.

[0050] In one embodiment of the present invention, such as Figure 11 As shown, the communication module 160 includes a roadside unit 161 and an on-board unit 162. The on-board unit 162 is installed at the bottom of the vehicle and is used to receive emergency driving request signals and length information, and transmit the emergency driving request signals and length information to the roadside unit 161. The roadside unit 161 is installed on one or both sides of the highway and is used to receive emergency driving request signals and length signals, transmit the emergency driving request signals and length information to the cloud platform 170, and receive control commands issued by the cloud platform 170, and transmit the control commands to the roadside controller 180.

[0051] In this embodiment, the vehicle-mounted unit 162 is located at the bottom of the vehicle and has wireless communication capabilities. It is used to receive emergency driving request signals and the length information of the vehicle from the vehicle controller 150 in real time, and transmit the emergency driving request signals and length information to the roadside unit 161.

[0052] The roadside unit 161, acting as a roadside communication node, is installed on poles on one or both sides of the highway. It receives emergency driving request signals and length information from the onboard unit 162 and uploads them to the cloud platform 170 to support the assessment of emergency passage conditions and the planning of emergency lanes. Simultaneously, the roadside unit 161 also receives control commands from the cloud platform 170 and transmits these commands to the corresponding roadside controller 180. This drives the protection unit to perform morphological adjustment actions, forming an emergency passage zone. This ensures the real-time accuracy of data and the rapid issuance of control commands during emergency response, thereby improving the efficiency and safety of emergency passage for vehicles in traffic conditions.

[0053] According to an embodiment of the present invention, a highway emergency passage system 100 based on vehicle-road-cloud, a first image acquisition module 110 and a lidar module 120 respectively acquire first vehicle information and second vehicle information on the highway and in front of the vehicle, and transmit the first vehicle information and second vehicle information to an edge computing unit 130. The edge computing unit 130 determines the road traffic status within a first preset distance range in front of the vehicle based on the first vehicle information and second vehicle information, and transmits the road traffic status to a cloud platform 170 through a communication module 160. At the same time, a second image acquisition module 140 acquires emergency lane occupancy status information, and a vehicle controller 150 acquires an emergency driving request signal, and transmits the occupancy status information and the emergency driving request signal to the cloud platform 170 through the communication module 160. The cloud platform 170 combines the road traffic status and lane occupancy information to determine whether the preset emergency passage conditions are met. If the preset emergency passage conditions are met, the cloud platform 170 sends a control command to the roadside controller 180 through the communication module 160. The roadside controller 180 drives the protection unit to adjust its shape according to the control command, forming an emergency passage area at the target location on one or both sides of the highway, allowing vehicles to pass through the emergency passage area. This solves the emergency passage needs when highway traffic is congested and the emergency lane is occupied, improves highway travel efficiency, and thus solves the problem of emergency travel needs.

[0062] Step S6: Upon receiving an emergency driving request signal, if the vehicle meets the preset emergency passage conditions based on road traffic conditions and lane occupancy information, a control command is sent to instruct the adjustment of the protective unit's configuration.

[0063] Step S7: Send a drive command according to the control command to adjust the shape of the protective unit, thereby forming an emergency passage area for the vehicle at the target location. The protective unit is set on one or both sides of the highway and is configured to be adjustable in shape to meet the emergency passage needs of the vehicle.

[0065] In one embodiment of the present invention, when it is determined that the vehicle meets the preset emergency passage conditions based on road traffic conditions and lane occupancy information, the control command for instructing the adjustment of the protective unit form is sent to the roadside controller through the communication module, including: when the road traffic condition is congested and the emergency lane is occupied, if it is determined that the vehicle meets the preset emergency passage conditions, then the control command is sent.

[0066] In one embodiment of the present invention, the emergency passage method for highways based on vehicle-road-cloud further includes: obtaining the length information of the vehicle and transmitting it to the cloud platform through a communication module.

The cloud platform 170 will comprehensively determine whether the preset emergency passage conditions are met by combining the road traffic status and lane occupancy information. If the preset emergency passage conditions are met, the cloud platform 170 sends a control command to the roadside controller 180 through the communication module 160. The roadside controller 180 drives the protection unit to adjust its shape according to the control command, forming an emergency passage area at the target location on one or both sides of the highway, allowing vehicles to pass through the emergency passage area. This solves the emergency passage needs when highway traffic is congested and the emergency lane is occupied, improves highway travel efficiency, and thus solves the problem of emergency travel needs.

[0074] According to an embodiment of the present invention, a computer-readable storage medium storing a vehicle-road-cloud-based highway emergency passage program, when executed by a processor, acquires first and second vehicle information on a vehicle traveling on the highway ahead of the vehicle, and determines the road traffic status within a first preset distance range ahead of the vehicle based on the first and second vehicle information. Simultaneously, it collects emergency lane occupancy status information. After acquiring an emergency travel request signal, it comprehensively considers the road traffic status and lane occupancy information to determine whether preset emergency passage conditions are met. If the preset emergency passage conditions are met, a control command is sent, and the protective unit is driven to adjust its shape according to the control command to form an emergency passage area at a target location on one or both sides of the highway, allowing vehicles to pass through the emergency passage area.
