These drawings and textual descriptions are not intended to limit the scope of the concept of the application by any means, but to illustrate the concept of the application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] The exemplary embodiments will be described in detail herein with reference to the attached drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] First, the terms involved in the application are explained:

[0045] Location-based services (LBS) are application services that utilize the positioning capabilities of mobile devices (such as smartphones, tablets, etc.) (such as GPS, Wi-Fi, base stations, Bluetooth, etc.) in conjunction with geographic information systems (GIS), mobile communication networks, and Internet technologies to provide users with information or services related to their current location.

[0046] In existing technologies, some two-wheeled vehicles have attempted to integrate traffic light countdown and navigation information display functions to reduce reliance on mobile phones during riding. However, current solutions still have significant limitations: on the one hand, these functions typically rely on dedicated hardware pre-installed on specific high-end models, supporting only a limited number of vehicles; on the other hand, traffic light information is mostly presented through projection of the complete navigation interface, failing to achieve lightweight and independent display of key traffic information (such as countdowns). Furthermore, while some solutions can display traffic light countdowns on the instrument cluster screen, this requires additional hardware support, increasing costs, and generally lacks a direct communication interface with traffic light cloud services, relying on indirect pushes from third-party map applications for information acquisition, thus limiting the functionality's versatility, real-time performance, and security.

[0047] The proposed two-wheeled vehicle traffic light countdown display system collects real-time vehicle location information through a positioning module and transmits this information to a cloud platform via a communication module. The cloud platform matches the nearest traffic light location based on the vehicle's position and calculates the countdown information in conjunction with the traffic light signal control system. Subsequently, the cloud platform sends the countdown information to the instrument display module via the communication module, which displays the countdown information in a combination of numbers and icons. Throughout the process, the hardware collaboration between the positioning and communication modules ensures real-time data transmission and low power consumption. The algorithm logic of the dynamic traffic information cloud platform implements traffic light location matching and countdown calculation, and the lightweight design of the instrument display module is adapted to the two-wheeled vehicle terminal, avoiding redundant information interference.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] Figure 1 A system diagram of the two-wheeled vehicle traffic light countdown display system provided in this application is shown below. Figure 1 As shown, the system includes an in-vehicle terminal and a cloud platform. The in-vehicle terminal includes a positioning module, a communication module, and an instrument display module. The positioning module and the instrument display module are respectively connected to the communication module, and the communication module is connected to the cloud platform.

[0050] a positioning module configured to obtain vehicle location information and transmit the vehicle location information to a cloud platform via a communication module;

[0051] a cloud platform configured to match a corresponding traffic light point based on the vehicle location information, calculate traffic light countdown information based on the traffic light point, and send the traffic light countdown information to the communication module;

[0052] an instrument display module configured to receive and display the traffic light countdown information sent by the communication module.

[0053] In some embodiments, the vehicle terminal can be an integrated electronic device installed on a two-wheeled vehicle for positioning, communication, data processing, and human-computer interaction. It can include a positioning module, a communication module, and an instrument display module, which can collect real-time vehicle location and state information and interact with the cloud platform to support navigation, remote monitoring, fault diagnosis, traffic light information prompting, and other intelligent applications.

[0054] The positioning module can be a hardware unit for obtaining vehicle location information, which can be based on a global navigation satellite system (GNSS) such as GPS, Beidou, etc., which can output latitude, longitude, speed, direction, and time information.

[0055] The communication module can be a hardware component responsible for data transmission between the vehicle terminal and the cloud platform, which can support cellular communication (such as 4G / 5G), Bluetooth, Wi-Fi, or Narrowband Internet of Things (NB-IoT) protocols to upload vehicle location information collected by the positioning module to the cloud platform and receive processing results (traffic light countdown information) from the cloud platform, thereby achieving bidirectional low-latency communication between the vehicle and the platform.

[0056] The cloud platform can be a data processing and intelligent analysis system deployed on a remote server, which has high concurrent access, geographic information matching, traffic state perception, and algorithm reasoning capabilities. It can match the preset traffic light point based on the vehicle location information uploaded by the vehicle, calculate the traffic light countdown information based on the traffic light point, and send the traffic light countdown information to the communication module.

[0057] In some embodiments, after obtaining the vehicle location information collected by the positioning module, the cloud platform can perform map matching with a high-precision map to determine the lane and direction of the vehicle. Then, in the preset traffic light geographic database, it retrieves the nearest and direction-matched traffic light point in front of the vehicle. Based on this, the cloud platform calculates the remaining time of the current phase (such as red or green) based on the signal timing scheme (such as fixed cycle parameters) of the traffic light and the current accurate time, generates traffic light countdown information, and sends it to the communication module for lightweight display on the instrument display module.

[0058] The countdown information of the traffic light can be the remaining time of the phase in which the target traffic light at the current intersection is located and the light state identifier thereof, and specifically includes: light state type, such as “red light”, “green light” or “yellow light”; remaining seconds, the remaining time (unit: seconds) of the duration of the light state, for example, “red light 18s” or “green light 5s”; and optional auxiliary information, such as the direction of the intersection (such as straight, left turn), signal cycle phase identifier, etc. The information is dynamically generated based on the front traffic light point matched by the vehicle position, in combination with a preset timing scheme or lead car trajectory data analysis, and is used to prompt the rider in a simple and intuitive way on the instrument display module, supporting safe and efficient passage.

[0059] The instrument display module can refer to a lightweight human-computer interaction interface installed in the vehicle instrument panel area and used for presenting key driving information to the user. In the embodiments of the present application, the module can be used to receive and display simplified prompt content such as traffic light countdown, avoid interference from complex navigation screens, and balance the visibility, safety and power consumption control, adapt to the limited installation space and use environment of two-wheeled vehicles. For example, in the urban commuting scenario, when the rider approaches the intersection, the instrument only displays “red light 18s” or “green light 5s” in high-contrast numbers, without the need to switch interfaces or check the mobile phone; in the night or strong light environment, the screen automatically adjusts the brightness and uses simple icons to assist in prompting, ensuring that the information is self-evident, reducing visual burden and improving riding safety.

[0060] The two-wheeled vehicle traffic light countdown display system provided in the embodiments of the present application obtains vehicle position information through the positioning module and uploads it to the cloud platform via the communication module; the cloud platform matches the corresponding traffic light point according to the position information, calculates the traffic light countdown information based on the point, and issues the result to the communication module; and the instrument display module receives and displays the traffic light countdown information. The entire system does not need to rely on specific pre-installed hardware or vehicle architecture modification, and only through the cooperation of the positioning, communication and display modules, simple and intuitive traffic light state prompts can be realized on the existing instrument of two-wheeled vehicles, avoiding checking the mobile phone navigation during riding, effectively reducing the operation interference and safety hazards.

[0061] Optionally, the positioning module includes a satellite navigation unit and an encryption unit, the satellite navigation unit is connected with the encryption unit, and the encryption unit is connected with the communication module; wherein,

[0062] The satellite navigation unit is configured to collect original coordinate data of the vehicle.

[0063] The encryption unit is configured to perform data encryption processing on the original coordinate data to obtain encrypted vehicle position information, and transmit the encrypted vehicle position information to the cloud platform through the communication module.

[0064] The satellite navigation unit can refer to a hardware module for receiving global navigation satellite system (such as Beidou, GPS, etc.) signals and calculating the original latitude, longitude, speed, time and other positioning information of the vehicle. The unit can integrate GNSS chips and antennas, and can output raw coordinate data in real time. For example, the UBLOX NEO-M8N chip generates WGS-84 coordinates by receiving satellite signals.

[0065] The encryption unit can refer to a processing module for securely protecting the raw coordinate data output by the satellite navigation unit. Symmetric or asymmetric encryption algorithms (such as AES, SM4, etc.) can be used to encrypt the location information and generate vehicle location data in ciphertext form. In this way, the location information can be ensured not to be stolen or tampered with during transmission to the cloud platform through the communication module. For example, the original WGS-84 coordinates (116.397428, 39.90923) are encrypted and converted to GCJ-02 coordinates (116.3975, 39.9093).

[0066] Thus, the satellite navigation unit can collect the original coordinate data (such as WGS-84 format) of the vehicle through satellite signals, then encrypt the data to meet the security requirements of geographic information, and convert it to GCJ-02 coordinate format. The encrypted GCJ-02 coordinates are transmitted to the cloud platform through the communication module to provide accurate location data for subsequent traffic light matching.

[0067] Optionally, the cloud platform further comprises an LBS service unit and a communication protocol unit, the LBS service unit and the communication protocol unit are connected, and the LBS service unit and the communication protocol unit are further connected with the communication module; wherein,

[0068] The LBS service unit is configured to query the vehicle location information based on the LBS service, determine the traffic light point within a preset range along the driving direction of the vehicle, and determine the initial traffic light countdown information according to the traffic light point; and dynamically adjust the initial traffic light countdown information based on the floating car trajectory data to obtain the traffic light countdown information.

[0069] The communication protocol unit is configured to send the traffic light countdown information to the communication module.

[0070] The LBS service unit can refer to a functional module deployed in the cloud platform for providing location-based services (Location-Based Service). Its main function is to accurately match the current position of the vehicle with the surrounding traffic signal facilities based on the received encrypted vehicle location information, in combination with the geographic information system (GIS) and the preset traffic light point database, and to provide spatial correlation basis for subsequent traffic light countdown calculation.

[0071] In the embodiment of the present application, the vehicle position information can be collected by the positioning module at a preset frequency (1s / time) and sent to the cloud platform, and the cloud platform determines the driving direction and speed of the vehicle according to the vehicle position information. According to the driving direction and speed of the vehicle, the LBS service unit can retrieve all the traffic light points in the driving direction within a preset range (such as within 100 meters in front) in the high-precision map database, and query the preset timing scheme of all the traffic light points; combined with the current system time, the current phase and the remaining time are calculated at a fixed period to obtain the initial countdown information.

[0072] After determining the initial countdown information, the crowd-sourced vehicle trajectory data (i.e. floating car trajectory data) passing through the traffic light in the near future is obtained, and the parking-start behavior of multiple vehicles in front of the intersection is analyzed by clustering; the actual green light start time is deduced by identifying the group start time; the initial countdown is corrected by calculating the current real phase remaining time; if the signal period is temporarily changed (such as peak extension green light), the dynamic result is used as the reference.

[0073] For example, the vehicle position (116.40, 39.91), the driving direction east→west;

[0074] The LBS service matches to the westbound traffic light of "xxx street-xxx road";

[0075] Query the preset timing, the current theoretical phase is the 25th second of the green light→initial countdown=5 seconds;

[0076] The cloud platform analyzes the trajectories of 200 floating cars in the past 5 minutes, and finds that the westbound vehicles generally start at the 43rd-46th second;

[0077] The actual green light duration is inferred to be 45 seconds, and the current has been on for 25 seconds→the real remaining time is 20 seconds;

[0078] The countdown is dynamically corrected from "5 seconds" to "20 seconds".

[0079] The communication protocol unit can refer to a software and hardware function module for specifying and managing the data interaction format, transmission process and security mechanism between the vehicle terminal and the cloud platform. It supports communication protocols such as TCP / IP, MQTT, CoAP or NB-IoT suitable for low-power wide-area networks, ensures that the encrypted vehicle position information can be reliably and efficiently uploaded to the cloud platform, and receives the traffic light countdown information issued by the cloud platform, realizes end-to-end data interconnection and instruction synchronization.

[0080] The preset range can refer to a spatial or distance threshold preset at the time of system design, used to limit the search boundary of the LBS service when matching the traffic light point. The range can be a fixed value (100 meters), or can be determined according to the driving speed of the two-wheeled vehicle, the visibility of the intersection, and the practicability of the signal prompt, for example, set to the road area between 50 meters and 200 meters in front of the current position of the vehicle. Within this range, the system only retrieves the traffic light point consistent with the driving direction of the vehicle to ensure the relevance of the matching result and the timeliness of the countdown information, and to avoid matching to the lateral, opposite, or too far intersection signal lamp.

[0081] In the embodiments of the present application, the communication protocol unit is further configured to:

[0082] The traffic light countdown information is transmitted to the communication module in a lightweight data packet format through the MQTT protocol.

[0083] The MQTT protocol can refer to a lightweight, low-bandwidth, and low-power Internet of Things communication protocol (Message Queuing Telemetry Transport) based on the publish / subscribe mode, suitable for terminal devices with unstable network environment or limited resources. In the embodiments of the present application, the MQTT protocol can ensure efficient and reliable transmission of traffic light countdown information between the cloud platform and the vehicle communication module.

[0084] The lightweight data packet format can refer to a compact structure and field-reduced data packaging method, which can be represented by JSON or binary encoding (such as Protocol Buffers, CBOR), and only contains necessary information fields, such as traffic light ID, current phase (red / green), countdown seconds, timestamp, etc. This format significantly reduces data volume and transmission delay, reduces power consumption and bandwidth occupation of the communication module, and adapts to the efficient communication needs of two-wheeled vehicle terminals under low-rate networks such as NB-IoT or 4G Cat.1.

[0085] In some embodiments, the data packet format of the issued traffic light countdown information can be: {“light_id”: “A203”, “color”: “green”, “countdown”: 12}.

[0086] In the embodiments of the present application, the preset range is determined according to the driving speed of the vehicle. The faster the driving speed of the vehicle, the larger the preset range. The slower the driving speed of the vehicle, the smaller the preset range.

[0087] When the vehicle travels at a high speed, the distance traveled in a unit of time is longer. If the preset range is too small, the system may not match the traffic light until the vehicle has approached or passed the intersection, and the countdown prompt cannot be provided in time. Therefore, the preset range is automatically enlarged (such as 200 meters) when the vehicle speed is increased, to ensure that the front traffic light is identified in advance and sufficient reaction time is left.

[0088] Conversely, when the vehicle travels at a low speed (such as in a traffic jam or during the starting stage), the vehicle travels slowly. If the search range is too large, multiple irrelevant intersections or opposite traffic lights may be introduced, causing mismatching. At this time, the preset range is reduced (such as 50 meters), the closest and most relevant traffic light is focused on, the matching accuracy is improved, and information interference is avoided.

[0089] In the embodiments of the present application, the preset range is set to satisfy:

[0090] ;

[0091] Among them, is the set minimum preset range; is the set maximum preset range; is the current speed; is the set minimum speed; is the set maximum speed.

[0092] Optionally, the instrument display module includes an instrument display disc, and the instrument display disc includes an icon area for displaying the display state of the traffic light at the traffic light point and the signal cycle time, different icon areas correspond to different traffic light points;

[0093] Among them, the display mode of the icon area is determined according to the time when the vehicle reaches the traffic light point; the higher the priority of the display of the corresponding icon area is, the less the time when the vehicle reaches the traffic light point is, and when the time when the vehicle reaches the traffic light point is less than the preset time, the display mode of the icon area is switched.

[0094] Among them, the instrument display disc can refer to a visual interface installed in front of the handlebar of the two-wheeled vehicle, which is used to intuitively present key driving information to the rider, and can be integrated in the original instrument of the vehicle.

[0095] The display state can refer to the actual light color of the current traffic light (such as a red light, a green light, or a yellow light). The signal cycle time can refer to the remaining countdown seconds of the current phase of the traffic light. Through the combination of the two, the rider can not only identify the light color, but also predict the traffic window, so as to reasonably control the vehicle speed and avoid sudden braking or misbreaking.

[0096] The icon area can refer to a number of independent visual units divided on the instrument display panel, each corresponding to a specific traffic light point in front, to synchronously display the light state and countdown of the intersection in a graphical manner (such as a circular / square icon combined with color and numbers).

[0097] The system dynamically adjusts the display priority of each icon area according to the estimated arrival time of the vehicle to each traffic light point. The closer the distance, the shorter the arrival time, and the more prominent the icon (such as enlargement, highlighting, or top placement).

[0098] When the estimated arrival time is less than a preset threshold (such as 10 seconds), the display mode is switched to a more eye-catching one (such as flashing, full-screen prompt, or voice linkage) to enhance the warning effect of the critical intersection.

[0099] In the embodiments of the present application, the instrument display panel further includes a direction icon area for displaying the driving direction of the vehicle when driving towards the traffic light point.

[0100] The direction icon area can refer to a graphical display unit on the instrument display panel for intuitively indicating the relative relationship between the current driving direction of the vehicle and the target traffic light point. It can be presented in the form of an arrow, a compass, or a road layout sketch, helping the rider quickly confirm whether the prompted traffic light countdown information corresponds to a straight, left turn, or right turn intersection, avoiding misjudgment due to direction confusion, and improving the accuracy and safety of human-computer interaction.

[0101] In the embodiments of the present application, the preset time is dynamically adjusted according to the speed distribution of the user riding the vehicle and the time spent at the intersection.

[0102] The preset time is not a fixed value, but is dynamically optimized according to the user's historical riding data: the system statistically analyzes the user's passing habits at different speeds and the average waiting time at the intersection (such as more frequent start-stop at low speed and less stopping at high speed), and accordingly adjusts the trigger threshold of "switching the icon display mode". For example, for users who quickly pass through the intersection, the threshold is set to 8 seconds, and for users who frequently stop at low speed, the threshold is set to 12 seconds, so as to ensure that the prompt timing is neither too early to interfere nor too late to warn, and to achieve personalized and context-aware interactive experience.

[0103] In some embodiments, the preset time can satisfy:

[0104] .

[0105] Where a and b are adjustment coefficients.

[0106] Figure 2 The interface schematic diagram of the instrument display panel provided by the embodiments of the present application is as follows: Figure 2As shown, the interface includes two icon areas, each of which is provided with a direction icon area, wherein the icon area is used to display the current light state (such as red light, green light) and the remaining seconds of the countdown of the corresponding traffic light point, and different icon areas correspond to different intersections or different driving directions (such as straight and left turn) of the front of the vehicle. The direction icon area intuitively indicates the driving direction applicable to the traffic light by using an arrow or a simplified road direction graph, helping the rider quickly identify the matching relationship between the prompt information and the self progress path, and avoiding misjudgment due to confusion of multiple intersections or multiple phase signals.

[0107] The two-wheeled vehicle traffic light countdown display system provided by the embodiment of the present application effectively avoids the rider from looking down to check the mobile phone navigation by independently presenting the traffic light countdown information on the instrument display screen, and significantly improves the riding safety. The terminal adopts a lightweight combination of a GNSS positioning module and an NB-IoT communication module, and can be adapted to the existing two-wheeled vehicle instrument without modifying the whole vehicle architecture, thereby greatly reducing the hardware cost. At the same time, the cloud platform has good expansibility, can be connected to the traffic light signal control systems of different cities, and dynamically fuses and analyzes combined with the probe vehicle trajectory data to realize high-precision countdown calculation based on the real traffic state, thereby ensuring the information accuracy. On this basis, the system displays the countdown number and the light state icon in combination, dynamically adjusts the refresh strategy and the prompt priority according to the vehicle speed to predict the arrival time at the intersection, further optimizes the information presentation logic, and reduces the user's cognitive and operation burden, so as to realize collaborative improvement in safety, cost, adaptability and user experience.

[0108] Figure 3 The flowchart of the two-wheeled vehicle traffic light countdown display method provided by the present application is shown in Figure 3 As shown, the method is applied to a vehicle terminal, and the method comprises the following steps:

[0109] S301, acquiring vehicle position information and transmitting the vehicle position information to a cloud platform, so that the cloud platform matches corresponding traffic light points according to the vehicle position information, calculates traffic light countdown information based on the traffic light points, and sends the traffic light countdown information to the vehicle terminal;

[0110] S302, receiving and displaying the traffic light countdown information.

[0111] The vehicle terminal can integrate a positioning module (GPS / Beidou), a communication module (4G / 5G / NB-IoT), a data processing unit (MCU) and an instrument display screen. The hardware configuration of the vehicle terminal can be as follows:

[0112] (1) Positioning module: UBLOX NEO-M8N GPS chip;

[0113] (2) Communication module: remove communication BC35-G NB-IoT module;

[0114] (3) Instrument display screen: 1.3-inch OLED monochrome screen (resolution 128 x 64).

[0115] The positioning module is built-in GNSS positioning module, which realizes the acquisition and return of the real-time position of the two-wheeled vehicle. The returned coordinates are in the format of longitude and latitude. The positioning module acquires the GNSS positioning coordinates, encrypts them in the terminal, deflects them into GCJ-02 coordinates, and then returns them to the cloud platform.

[0116] In use, the positioning module in the vehicle terminal acquires the vehicle position in real time, and uploads the position to the cloud platform through the wireless communication module at a frequency of 1 second per time.

[0117] The cloud platform can access the city traffic signal control system (red light cloud service) to obtain real-time intersection light state data. The push interface service of dynamic traffic information needs to face different vehicle terminal forms and can adapt to systems including Linux, Android and FreeRTOS special vehicle terminal operating systems.

[0118] The cloud platform can be built-in with national navigation electronic map data and basic LBS service, and mark the point of each intersection red light, gather dynamic traffic information, on the one hand, access the city traffic signal control system (red light cloud service) to obtain real-time intersection light state data; on the other hand, through the access of floating car dynamic trajectory data, carry out big data analysis, calculate red light state, traffic event and other information. The obtained dynamic traffic information such as red light state and traffic event is associated and matched with the electronic map.

[0119] Among them, the cloud platform can calculate the red light phase period and the remaining time according to the change rule of the red light state, and extract the distance data according to the vehicle position and the intersection red light position, remind according to the red light countdown, judge the speed and time of the vehicle passing, and remind.

[0120] After generating the countdown instruction and reminding message, the cloud platform push interface service pushes the dynamic traffic information in the MQTT lightweight protocol, which is convenient for terminal user data query and display.

[0121] Among them, the red light state data packet format issued is: {“light_id”: “A203”, “color”: “green”, “countdown”: 12}.

[0122] The instrument display screen receives the instruction issued by the cloud platform to display the countdown information in the form of numbers and icons.

[0123] The instrument display screen simplifies the displayed content, i.e., only displays countdown numbers (such as "15s") and light state icons (red / yellow / green).

[0124] Dynamic refresh: according to the vehicle speed to predict the time to reach the intersection, automatically switch the display priority.

[0125] The instrument display module only displays the countdown numbers and light state colors (red / yellow / green), and does not display the complete map interface.

[0126] Display logic:

[0127] (1) Countdown seconds: display a yellow flashing icon and a number;

[0128] (2) Countdown seconds: display a static icon and a number.

[0129] In some embodiments, dynamic traffic information such as traffic events can also be pushed and displayed on the two-wheeled vehicle instrument and event reminders.

[0130] In some embodiments, the vehicle terminal also includes a communication module, which is responsible for returning the positioning coordinates of the positioning module to the platform; and transmitting the dynamic traffic information of the red light matched by the dynamic traffic information cloud platform to the two-wheeled vehicle display module.

[0131] Among them, the communication protocol adopts the MQTT lightweight protocol to reduce the data transmission delay.
