Description

A UWB-based real-time communication method and system for vehicles and toll stations

[0001] This disclosure claims priority to Chinese Patent Application No. 202410937787.8, filed on July 12, 2024, entitled "A UWB-based method and system for real-time communication between vehicles and toll stations", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of contactless payment technology, and in particular to a UWB-based instant communication method and system for vehicles and toll stations. Background Technology

[0003] With rapid socio-economic development and a significant improvement in residents' quality of life, modern consumers' expectations for automobiles have far exceeded the traditional scope of a means of transportation, turning instead to a pursuit of a more comprehensive, personalized, and intelligent travel experience. In this transformation of the automotive market, consumers' demands for overall comfort, intelligence, convenience, and safety performance have reached unprecedented levels.

[0004] In terms of comfort, consumers not only pay attention to the spaciousness of the interior, the comfort of the seats, and the quality of the audio system, but also increasingly focus on the vehicle's shock absorption performance, noise control, and air quality regulation, striving to enjoy a home-like warmth and comfort during driving and riding.

[0005] Intelligentization is another major trend in the current automotive industry. Consumers expect cars to have advanced driver assistance systems, such as automatic parking, adaptive cruise control, and lane keeping assist, to reduce driving burden and improve driving safety. At the same time, the widespread adoption of in-vehicle connectivity technology has turned cars into mobile intelligent terminals, allowing users to easily access navigation, entertainment, communication, vehicle status monitoring, and other functions through voice control, gesture recognition, or touchscreens, greatly enriching driving pleasure and convenience.

[0006] Specifically, in highway toll scenarios, the traditional manual card-taking method is not only inefficient and prone to causing traffic congestion and affecting the travel experience, but also increases labor costs and error rates. While the existing ETC (Electronic Toll Collection) lanes alleviate this problem to some extent, their usage is quite difficult. Drivers need to purchase and install an ETC device, which must be linked to a specific bank card. This cumbersome process deters many drivers, especially those who only occasionally use highways or have vehicles for short periods, making it inflexible and inconvenient. Summary of the Invention

[0007] The purpose of this invention is to provide a UWB-based real-time communication method and system for vehicles and toll stations, in order to solve the problems of low efficiency and poor flexibility in the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] In a first aspect, the present invention provides a UWB-based real-time communication method for vehicles and toll stations, comprising:

[0010] When a vehicle enters the first toll station, the vehicle information and the toll station information are exchanged for the first time between the vehicle and the first toll station via UWB communication.

[0011] When a vehicle exits the second toll station, UWB communication is used to exchange vehicle information and toll station information a second time between the vehicle and the second toll station.

[0012] Based on the vehicle driving information and corresponding cost information obtained after two information exchanges, mobile payment can be made.

[0013] Furthermore, obtaining vehicle information and toll station information specifically includes:

[0014] Vehicle license plate number, current mileage, and toll station location.

[0015] Furthermore, the UWB communication method is implemented using multiple UWB modules, including a UWB wireless communication module, vehicle-mounted UWB anchor points, and toll station UWB anchor points. The UWB wireless communication module is connected to the vehicle controller, the vehicle-mounted UWB anchor points are evenly distributed on the vehicle, and the toll station UWB anchor points are installed at the entrance and exit of the toll station, covering the passage area.

[0016] Furthermore, vehicle-mounted UWB anchor points are installed at the front, rear, left, right, and roof of the vehicle to achieve three-dimensional positioning.

[0017] Furthermore, during the first exchange, the vehicle obtains the toll station location information and stores it in the vehicle controller, while the first toll station obtains the vehicle's license plate information and current travel distance information and uploads it to the toll station's toll collection system.

[0018] Furthermore, during the second exchange, the second toll station obtains the vehicle's current travel distance, license plate information, and the toll station's location information from the first exchange; the difference between the two travel distances is used to obtain the total travel distance, and the travel distance is verified using the toll station's location information from the two exchanges. If the travel distance is correct, the toll information is sent to the vehicle.

[0019] Furthermore, the vehicle controller is also connected to a Bluetooth module, which connects to a mobile payment tool. The payment information is sent to the payment tool via the Bluetooth module for mobile payment.

[0020] Secondly, the present invention provides a UWB-based real-time communication system for vehicles and toll stations, comprising:

[0021] The data exchange module is used to enable the first exchange of vehicle information and toll station information between the vehicle and the first toll station via UWB communication when the vehicle enters the first toll station.

[0022] When a vehicle exits the second toll station, UWB communication is used to exchange vehicle information and toll station information a second time between the vehicle and the second toll station.

[0023] The settlement module is used to make mobile payments based on the vehicle driving information and corresponding cost information obtained after two information exchanges.

[0024] Thirdly, the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of a UWB-based real-time communication method for vehicles and toll stations.

[0025] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of a UWB-based real-time communication method between vehicles and toll stations.

[0026] Compared with the prior art, the present invention has the following technical effects:

[0027] This invention achieves high-precision real-time communication and positioning between vehicles and toll stations through the combined use of UWB wireless communication modules, vehicle-mounted UWB anchor points, and toll station UWB anchor points. This three-dimensional positioning method (such as installing vehicle-mounted UWB anchor points at the front, rear, left, right, and roof of the vehicle) ensures accurate identification and tracking of vehicles in the toll station area, providing a precise data foundation for subsequent toll calculation.

[0028] This invention involves two information exchanges via a UWB module when a vehicle enters and exits a toll station. This exchange transmits not only basic vehicle information (such as license plate number and mileage) but also updates the vehicle's location and driving status in real time. This instant communication mechanism significantly reduces data transmission and processing time, improving toll collection efficiency.

[0029] This invention accurately calculates the toll payable by comparing the distance a vehicle travels when entering and exiting a toll station, and verifying the accuracy of the travel path by combining the toll station's location information. This method effectively avoids the problems of mileage error and unfair billing that may exist in traditional toll collection methods.

[0030] This invention connects the vehicle controller with a Bluetooth module and a mobile payment tool, enabling toll information to be directly pushed to the payment tool for payment. This process greatly simplifies the payment process, improves the user's payment experience, and also reduces the manual operation costs at toll booths.

[0031] The UWB technology of this invention, with its high bandwidth, low power consumption, and strong anti-interference capabilities, ensures the reliability and security of data transmission. Furthermore, the system's anti-cheating capabilities are further enhanced through a two-stage information exchange and distance verification mechanism.

[0032] This technical solution enables intelligent communication and automated toll collection between vehicles and toll stations, providing strong support for the construction of smart transportation and smart cities. With the continuous development of technologies such as the Internet of Things and big data, this solution is expected to integrate with more intelligent systems, further enhancing the level of intelligence in traffic management.

[0033] In summary, this UWB-based real-time communication method between vehicles and toll stations demonstrates significant technical benefits in improving toll collection efficiency, accurate billing, convenient payment, system security, and intelligence.

[0034] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0039] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0040] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this invention generally indicates that the preceding and following objects have an "or" relationship.

[0041] It should be understood that although terms such as first, second, third, etc., may be used in the embodiments of the present invention to describe the preset range, these preset ranges should not be limited to these terms. These terms are only used to distinguish the preset ranges from one another. For example, without departing from the scope of the embodiments of the present invention, the first preset range may also be referred to as the second preset range, and similarly, the second preset range may also be referred to as the first preset range.

[0042] Depending on the context, the word "if" as used here can be interpreted as "when," "when," "in response to determination," or "in response to detection." Similarly, depending on the context, the phrase "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0043] The accompanying drawings illustrate various structural schematic diagrams according to embodiments disclosed in this invention. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0044] Example 1, please refer to Figure 1, the present invention provides a UWB-based real-time communication method between vehicles and toll stations, including:

[0045] In step S101, when the vehicle enters the first toll station, the vehicle information and the toll station information are exchanged for the first time between the vehicle and the first toll station via UWB communication.

[0046] In step S102, when the vehicle exits the second toll station, the vehicle information and the toll station information are exchanged a second time between the vehicle and the second toll station via UWB communication.

[0047] In step S103, mobile payment is performed based on the vehicle driving information and corresponding cost information obtained after the two information exchanges.

[0048] It's understandable that when a vehicle travels from point A to point B via a highway, it enters the highway at the first toll station at point A and exits at the second toll station at point B. The information exchange between the vehicle and the toll stations clearly occurs as the vehicle approaches both the first and second toll stations. Therefore, "entering the first toll station" refers to the vehicle approaching the first toll station at the highway entrance, and similarly, "exiting the second toll station" refers to the vehicle approaching the second toll station at the highway exit.

[0049] The UWB communication method mentioned above is implemented using multiple UWB modules, including a UWB wireless communication module, a vehicle-mounted UWB anchor point, and a toll station UWB anchor point. This invention achieves UWB communication through the combined use of the UWB wireless communication module, vehicle-mounted UWB anchor point, and toll station UWB anchor point, thereby enabling high-precision real-time communication and positioning between the vehicle and the toll station. The vehicle-mounted UWB anchor point can be installed at the front, rear, left, right, and roof of the vehicle. This three-dimensional positioning method ensures accurate identification and tracking of the vehicle within the toll station area, providing a precise data foundation for subsequent toll calculation.

[0050] UWB anchor points at toll booths can be installed at both the entrance and exit of the toll booth, covering the entire traffic area. Understandably, locations on a highway with entrances and exits (e.g., location A) will have entrance and exit toll booths. Vehicles can enter the highway through the entrance toll booth at location A and exit through the exit toll booth at location A. Installing UWB anchor points at the entrance and exit of the toll booth means installing UWB anchor points at each entrance and exit toll booth. Specifically, the toll booth UWB anchor points can be installed at a predetermined distance from each entrance and exit toll booth, facing the direction of oncoming traffic, so that communication can be established in advance with the vehicle-mounted UWB anchor point as the vehicle approaches.

[0051] Example 2: This invention provides a UWB-based real-time communication method between vehicles and toll stations, specifically including:

[0052] When a vehicle enters the first toll station, UWB communication is used to exchange vehicle information and toll station information between the vehicle and the first toll station for the first time.

[0053] When a vehicle exits the second toll station, UWB communication is used to exchange vehicle information and toll station information a second time between the vehicle and the second toll station.

[0054] Based on the vehicle driving information and corresponding cost information obtained after two information exchanges, mobile payment can be made.

[0055] The above method can be implemented using the following system:

[0056] 1. A highway toll collection system that communicates with vehicle-mounted devices via UWB (encrypted).

[0057] 2. A multi-UWB anchor point positioning system deployed on the vehicle. This positioning system can locate UWB anchor points on highways. The system can also receive toll information from the highway toll system and communicate with a mobile app linked to the vehicle via Bluetooth or network. This app can be linked to a mobile wallet and can make payments automatically.

[0058] Specifically, the multi-UWB anchor point positioning system deployed in the vehicle includes multiple UWB positioning antennas installed on the vehicle body, as well as a positioning determination system. The determination system can calculate the UWB anchor point of the vehicle based on the UWB anchor point of the highway toll station, thereby determining the position of the UWB anchor point and accurately locating the position distance information between the UWB anchor point and the vehicle. When the distance to the vehicle reaches a certain distance, the vehicle's UWB anchor point communicates with the highway toll station's UWB anchor point to transmit vehicle identification information to open the gate for entry. When exiting the highway, it transmits vehicle information, highway entrance information, and toll information. This transmission is encrypted. Afterward, the vehicle control system transmits this information to the vehicle's bound app via Bluetooth, and then from the app to the mobile wallet, realizing a seamless payment, seamless exit, and fast passage user experience.

[0059] Example 3: A UWB-based real-time communication method between vehicles and toll stations, comprising:

[0060] When a vehicle enters the first toll station, UWB communication is used to exchange vehicle information and toll station information between the vehicle and the first toll station for the first time.

[0061] When a vehicle exits the second toll station, UWB communication is used to exchange vehicle information and toll station information a second time between the vehicle and the second toll station.

[0062] Based on the vehicle driving information and corresponding cost information obtained after two information exchanges, mobile payment can be made.

[0063] The above method utilizes a highway toll collection system and a vehicle positioning system. More specifically, it is achieved through the interaction between UWB anchor points deployed in the highway toll collection system and vehicle UWB anchor points deployed in the vehicle positioning system. The specific interaction includes the following characteristics:

[0064] 1. The highway toll collection system is equipped with UWB anchor points and can communicate with anchor points using the same communication method via UWB;

[0065] 2. When a vehicle approaches the UWB anchor point of the highway toll system, the vehicle's UWB anchor point is scanned, and when it reaches a certain distance, it can quickly identify the distance information between the vehicle and the external anchor point. At this time, it communicates with the external anchor point to transmit the vehicle's unique information, such as the license plate number and the vehicle's remaining driving range. When the vehicle exits the highway, the highway exit toll system transmits the vehicle's billing information back to the vehicle through the UWB anchor point.

[0066] 3. The vehicle positioning system obtains billing information and communicates with the vehicle's bound app via network or Bluetooth to transmit relevant information;

[0067] 4. Automatic payment can be completed by linking the mobile app to the mobile wallet;

[0068] 5. The toll gate at the highway exit is raised, allowing vehicles to leave without any sensor lag and pass through quickly.

[0069] 6. Set up UWB base stations appropriately along highways to enable vehicles to communicate with base stations via UWB.

[0070] Example 4: A UWB-based real-time communication method between vehicles and toll stations, implemented using the following steps:

[0071] 1. When a user drives a vehicle equipped with a UWB positioning system near a highway exit, the vehicle's positioning system automatically establishes a connection with the toll collection system, which has UWB anchor points, once a certain distance is reached. These toll station UWB anchor points are installed at the entrance and exit of the toll station, covering the entire passageway. The vehicle-mounted UWB anchor points are evenly distributed throughout the vehicle, specifically installed at the front, rear, left, right, and roof, enabling three-dimensional positioning.

[0072] 2. The toll collection system establishes a connection and communication with the nearest approaching vehicle and quickly identifies its specific location and distance. When a certain distance is reached, the highway toll collection system's UWB anchor point and the vehicle's UWB anchor point communicate via UWB and transmit the vehicle's unique information and toll fees, etc.

[0073] 3. The vehicle terminal obtains the toll amount for the vehicle;

[0074] 4. The vehicle positioning system communicates with the vehicle's paired app via network or Bluetooth and transmits relevant information;

[0075] 5. The mobile app automatically makes payments based on the linked mobile wallet, etc.

[0076] 6. Once the highway toll system completes payment confirmation, the barrier lifts, allowing vehicles to pass through seamlessly and quickly.

[0077] The overall system architecture is designed as follows:

[0078] Hardware layer: includes multiple UWB positioning antennas (at least three to achieve three-dimensional positioning) installed on the vehicle body, vehicle controller (including Bluetooth module), and mobile APP (installed on the user's mobile phone).

[0079] Communication layer: UWB wireless communication module (for encrypted communication between the vehicle and the toll station), Bluetooth module (for communication between the vehicle control system and the mobile APP).

[0080] Software layer:

[0081] Vehicle-side software: Responsible for UWB positioning data processing, communication with toll stations, and Bluetooth data transmission.

[0082] Toll station software: responsible for UWB anchor point management, vehicle location determination, toll information generation and encrypted transmission.

[0083] Mobile App: Receives vehicle data, interacts with mobile wallet, and enables seamless payment.

[0084] High-strength encryption algorithms such as AES are used to encrypt UWB communication data to ensure the security of data transmission.

[0085] Establish an identity verification mechanism to ensure that only legitimate vehicles and toll stations can communicate.

[0086] The hardware deployment and configuration are as follows:

[0087] UWB positioning antennas are installed at key locations such as the front, rear, left, right, and top of the vehicle to ensure full coverage and accurate measurement of the distance to the UWB anchor point at the toll station.

[0088] Ensure a stable connection between the UWB antenna and the vehicle control system, and that it is waterproof and dustproof.

[0089] Install fixed UWB anchor points at the entrances and exits of highway toll stations to ensure coverage of the entire passage area.

[0090] The anchor points are calibrated and adjusted to ensure they can accurately measure and identify the location information of passing vehicles.

[0091] In another embodiment of the present invention, a UWB-based real-time communication system for vehicles and toll stations is provided, which can be used to implement the above-mentioned UWB-based real-time communication method for vehicles and toll stations. Specifically, the system includes:

[0092] The data acquisition module is used to acquire vehicle information and toll station information;

[0093] The data exchange module is used to enable the initial exchange of vehicle information and toll station information between the vehicle and the toll station via the UWB module when the vehicle enters the toll station.

[0094] When a vehicle exits the toll station, the UWB module enables a second exchange of vehicle information and toll station information between the vehicle and the toll station.

[0095] The settlement module is used to obtain vehicle driving information and corresponding cost information after two information exchanges, and then make mobile payments.
