[0040] In order to effectively solve the shortcomings of traditional technologies in scene perception, data collaboration and early warning decision-making, and significantly improve the intelligence level and service quality of the assisted driving system, this application provides an embodiment of a vehicle driving intelligent control method, see Figure 1 The vehicle driving intelligent control method specifically includes the following contents:
[0041] Step S101: Setting up analysis and identification units along the road. The analysis and identification units include edge boxes, smart cameras, and environmental detection equipment. The edge boxes establish a communication connection with and register with the cloud platform. The smart cameras include license plate capture cameras and wide-angle cameras. The environmental detection equipment collects road environment parameters. Deploying an on-board module on the vehicle side. The on-board module establishes a connection with and registers with the cloud platform via an IoT communication module. The on-board module calls the vehicle-machine interface to obtain the vehicle's driving trajectory. Based on the driving trajectory, multiple analysis and identification units are divided into regional linkage networks.
[0042] Optionally, this embodiment deploys analysis and identification units at key road nodes along major thoroughfares, such as highways and urban expressways. Representative monitoring points are selected by analyzing road geometry and historical traffic data at locations such as accident-prone sections, elevated bridges, and tunnel entrances and exits. A standardized pole structure is constructed at each monitoring point, with the equipment mounted using adjustable cantilever brackets to ensure that the height and angle of the equipment meet monitoring requirements.
[0043] The edge box in this embodiment uses an industrial-grade embedded computing platform equipped with a high-performance ARM processor and AI accelerator chip, supporting edge computing and deep learning algorithms. The edge box connects to the Internet of Things via a 4G / 5G dual-mode communication module, generates a registration key based on the unique device serial number, and establishes a secure communication link with the cloud platform using the TLS encryption protocol. During the registration process, the edge box reports information such as the device's location coordinates and coverage range to the cloud platform, which assigns it a unique identifier and returns an authorization certificate.
[0044] The smart camera in this embodiment consists of two independent imaging units. The license plate capture camera uses a high-definition CCD sensor, equipped with an auto-iris lens and a fill light, enabling clear license plate image capture in all lighting conditions. The wide-angle camera uses a fisheye lens with a 180-degree field of view, enabling panoramic road monitoring. The two cameras undergo angle calibration and spatial mapping to establish an image coordinate system, enabling multi-target tracking and spatial positioning.
[0045] The environmental monitoring device in this embodiment integrates multiple sensors, including a laser visibility meter, a surface temperature sensor, a humidity sensor, and a light sensor. The laser visibility meter measures atmospheric transmittance based on the scattering principle and calculates visibility values. A surface sensor array is embedded in the road surface to monitor road surface temperature distribution and water accumulation in real time. All sensor data is connected to the edge box via an industrial bus, enabling unified management and data fusion.
[0046] This embodiment deploys a standardized onboard module on the vehicle side, using a plug-and-play design and connecting to the vehicle's CAN bus via the OBD interface. The onboard module incorporates a high-precision positioning chip and inertial measurement unit, integrating multi-mode positioning signals such as GPS and Beidou to achieve sub-meter positioning accuracy. An IoT communication module establishes a data channel with the cloud platform, using the lightweight MQTT protocol to transmit vehicle status data.
[0047] The on-board module in this embodiment uses a standardized interface to call the vehicle computer system to obtain vehicle status data such as engine speed, vehicle speed, and steering wheel angle. Combined with high-precision positioning information, it constructs a vehicle motion model and generates an accurate driving trajectory. The on-board module uploads this trajectory data to a cloud platform at regular intervals. The cloud platform maps the trajectory points onto the road network using an electronic map to predict the vehicle's future driving path.
[0048] This embodiment innovatively proposes a method for dynamically constructing a regional linkage network. Based on the predicted vehicle path, the cloud platform extracts analysis and identification units along the route and constructs a directed graph structure based on geospatial relationships. Nodes in the graph represent analysis and identification units, and edges represent the relationships between units. By assigning network priorities and establishing a cascading trigger mechanism, when a node detects an anomaly, it can quickly notify downstream nodes for a coordinated response.
[0049] This embodiment utilizes a distributed edge computing architecture, offloading computational tasks like data collection and feature extraction to edge nodes, reducing the load on the cloud platform. Both the edge box and the onboard module possess local computing capabilities, enabling data preprocessing and preliminary analysis. Furthermore, through unified cloud platform scheduling, device collaboration is achieved, building an intelligent perception network covering the entire road area.
[0050] This embodiment addresses the issues of dispersed equipment, data silos, and delayed response times found in traditional road monitoring systems. Through edge computing and regional linkage mechanisms, it enables real-time perception of road conditions and rapid early warnings. In practical applications, this solution can significantly improve traffic safety in scenarios such as inclement weather and frequent accidents. Particularly in closed road environments such as highways, the system can provide drivers with accurate road condition information and safety warnings, effectively reducing the risk of traffic accidents.
[0051] Step S102: The license plate capture camera acquires the vehicle's license plate number, license plate color, and vehicle model information, the wide-angle camera acquires real-time road images, the environmental detection equipment acquires road visibility and road surface state parameters, the edge box extracts vehicle driving characteristics based on the real-time road images, the edge box trains a traffic flow prediction model and a risk assessment model based on the vehicle driving characteristics, and sends the vehicle driving characteristics, traffic flow prediction results, risk assessment values, and environmental parameters collected by each analysis and recognition unit to the cloud platform;
[0052] Optionally, this embodiment adopts a multi-stage processing strategy for license plate capture. The license plate capture camera triggers capture based on vehicle front-end detection and uses adaptive exposure technology to ensure image quality. The edge box runs an improved YOLOv5 object detection algorithm to locate the license plate area and combines morphological processing to achieve license plate character segmentation. Character recognition is performed using a deep convolutional neural network. The model is trained using a noisy synthetic dataset to improve recognition accuracy in complex environments. Vehicle type classification is also performed based on vehicle body contour features, supporting accurate recognition of various vehicle types such as sedans, buses, and trucks.
[0053] The wide-angle camera in this embodiment captures real-time road images at a sampling rate of 25 frames per second. The edge box processes the video stream in real time and uses an improved DeepSORT algorithm to track multiple targets. The algorithm integrates appearance and motion features during the feature extraction phase to improve vehicle tracking stability. Vehicle motion parameters, including instantaneous speed, acceleration, and lane change frequency, are calculated by tracking trajectories. Furthermore, the relative distance and speed between vehicles are calculated based on spatial mapping relationships to construct vehicle interaction behavior profiles.
[0054] The environmental monitoring equipment in this embodiment uses a multi-sensor collaborative sensing solution. A laser visibility meter calculates visibility by measuring the atmospheric attenuation coefficient, with a sampling period of one minute. A surface sensor array monitors road surface temperature distribution in real time and, combined with humidity data, determines road surface conditions, such as dryness, dampness, waterlogging, or ice. A light sensor monitors changes in ambient brightness and is used to adjust camera parameters and fill-light strategies. All environmental parameters undergo data filtering and smoothing to ensure data quality.
[0055] This embodiment innovatively designs a traffic flow prediction model. The model utilizes a long short-term memory (LSTM) network architecture, and its input features include time-series data such as historical traffic volume, average speed, and vehicle type composition. An attention mechanism captures traffic flow patterns at different time scales, improving prediction accuracy. The model is trained using a sliding window strategy, with the window size dynamically adjusted based on the prediction time span. The prediction results include traffic flow status at multiple future time points, providing a basis for traffic control decisions.
[0056] This example constructs a risk assessment model based on multidimensional features. It uses the Gradient Boosting Decision Tree (GBDT) algorithm. Input features include behavioral characteristics such as vehicle spacing, relative speed, acceleration, and lane changes, as well as environmental characteristics such as visibility and road conditions. The model analyzes historical accident data to establish a mapping between these features and risk levels. The assessment results are output as probabilities, providing a direct reflection of the safety risk level of the current road section.
[0057] This embodiment designs an efficient data transmission mechanism. The edge box packages vehicle characteristics, prediction results, and risk assessment values into structured data, using the protobuf encoding format to reduce transmission overhead. Data packets are uploaded to the cloud platform at a fixed interval, which can be dynamically adjusted based on network conditions. For emergencies, a real-time push mechanism is used to ensure the timely delivery of critical information. The cloud platform synchronizes and analyzes data using timestamps.
[0058] This embodiment implements a computing architecture that integrates edge intelligence and the cloud. Real-time-critical tasks such as feature extraction and target tracking are deployed on edge boxes to reduce network transmission latency. Model training and optimization are performed in the cloud, with updated model parameters regularly distributed to edge nodes. This layered architecture ensures the system's real-time responsiveness while supporting continuous model optimization and evolution.
[0059] This embodiment addresses the challenges of traditional traffic monitoring systems, such as insufficient perception and low prediction accuracy, through multi-source data fusion and intelligent analysis. In practical applications, this solution accurately identifies vehicle characteristics, predicts traffic flow trends, and promptly identifies safety hazards. Especially in scenarios such as inclement weather and complex road conditions, the system can comprehensively analyze multi-dimensional data to provide reliable decision-making support for traffic management and vehicle warnings, effectively improving road efficiency and safety.
[0060] Step S103: The cloud platform receives data uploaded by a plurality of the analysis and identification units, determines whether to trigger regional linkage based on a preset road traffic strategy and the risk assessment value, and when regional linkage is triggered, issues linkage instructions to the relevant analysis and identification units according to the regional linkage network and establishes a communication link, receives the traffic flow prediction results uploaded by the relevant analysis and identification units, and generates warning information including real-time road conditions, recommended detour routes and safe vehicle speeds based on the traffic flow prediction results, and sends the warning information to the vehicle-mounted module corresponding to the license plate number for broadcast.
[0061] Optionally, this embodiment innovatively implements intelligent data collection and processing at the edge. The license plate capture camera uses a two-stage detection mechanism based on a combination of image processing and deep learning to locate license plates. The first stage uses an improved YOLOv5 model for rough positioning, while the second stage employs a high-precision license plate character segmentation network for accurate character-level recognition. This maintains a high recognition accuracy even in complex lighting and occlusion conditions.
[0062] The wide-angle camera in this embodiment uses a multi-scale object detection algorithm to detect and track key targets such as vehicle outlines, pedestrians, and road markings in real time. It calculates driving characteristics such as the vehicle's instantaneous speed, acceleration, and lane departure through spatiotemporal feature analysis. The edge box utilizes a stream processing architecture to establish a feature extraction pipeline, enabling real-time processing of video streams with millisecond latency.
[0063] This example builds a traffic flow prediction model based on a long short-term memory (LSTM) network. The model input features include time-series data such as historical traffic flow, average speed, and vehicle density, while also incorporating environmental factors such as weather conditions and road surface conditions. An attention mechanism captures the correlation between different features, improving prediction accuracy. The prediction results include traffic flow status at multiple future time points, providing a basis for predictive decision-making in traffic management.
[0064] This embodiment designs a risk assessment model based on random forests. The model input variables include multi-dimensional features such as vehicle spacing, relative speed, weather visibility, and road friction coefficient. Feature importance analysis identifies key factors that significantly impact traffic safety. The model outputs a risk assessment value that reflects the probability of a traffic accident occurring on the current road section and is used to trigger an early warning mechanism. In practical applications, the model is continuously optimized through online learning to adapt to the safety characteristics of different scenarios.
[0065] This embodiment optimizes the data transmission strategy. The edge box uses a hierarchical caching mechanism to store raw data, feature data, and model prediction results separately. Data upload uses batch processing, dynamically adjusting the batch size based on data priority and network conditions. Data compression and incremental update mechanisms reduce transmission bandwidth usage.
[0066] This embodiment implements an intelligent regional linkage mechanism based on road traffic strategies. After receiving data uploaded by each analysis and recognition unit, the cloud platform first performs data quality assessment and outlier detection. When the risk assessment value of a road section exceeds a threshold, a regional linkage decision is triggered. The linkage range is determined based on a traffic flow propagation model, taking into account factors such as traffic flow direction and traffic saturation.
[0067] This embodiment builds a warning information generation engine that calculates the congestion index for each road section based on traffic flow predictions. A route planning algorithm comprehensively considers factors such as distance, time, and safety to generate personalized detour suggestions for different vehicle types. Recommended safe speeds are calculated based on current road conditions, weather conditions, and vehicle characteristics to ensure safe driving.
[0068] This embodiment implements a precise information push mechanism. Warning information is distributed to the onboard module via a message queue system, supporting message priority management and reliable transmission. After receiving the warning information, the onboard module selects the appropriate broadcast timing based on the vehicle's driving status and converts the text information into clear voice prompts using speech synthesis technology.
[0069] Through the above technological innovations, this embodiment effectively addresses the problems of traditional traffic warning systems, such as blind spots, delayed predictions, and untimely linkage. In practical applications, this solution accurately identifies traffic risks, predicts traffic flow changes in advance, and enables rapid response through a regional linkage mechanism. Especially in scenarios such as inclement weather and frequent accidents, the system can provide drivers with precise warning information and safety recommendations, significantly improving road safety and efficiency.
[0070] As can be seen from the above description, the vehicle driving intelligent control method provided by the embodiment of the present application can realize multi-dimensional data collection through edge boxes, smart cameras and environmental detection equipment. The regional linkage network is dynamically divided based on the vehicle driving trajectory, and the traffic flow prediction and risk assessment model is trained at the edge. The cloud platform integrates the data of multiple analysis and recognition units, triggers the regional linkage mechanism according to the road traffic strategy and risk assessment value, and generates accurate early warning information including real-time road conditions, recommended detour routes and safe vehicle speeds. This method effectively solves the shortcomings of traditional technologies in scene perception, data collaboration and early warning decision-making, and significantly improves the intelligence level and service quality of the assisted driving system.
[0071] In one embodiment of the vehicle driving intelligent control method of the present application, the following contents may also be specifically included:

The edge box then establishes a secure communication link with the cloud platform based on the registration authorization information.
[0073] Step S202: The edge box establishes a communication connection with the smart camera and the environmental detection device, calibrates the angle and focal length of the smart camera, sets the license plate capture camera to point in the direction of vehicle traffic, and sets the wide-angle camera to a panoramic road monitoring angle. A sub-device management group is established with the edge box as the center, and the sampling period and trigger threshold of the environmental detection device are configured. The edge box obtains environmental parameters including visibility, temperature, humidity and light intensity from the environmental detection device at preset time intervals.
[0074] Optionally, this embodiment identifies key monitoring locations by analyzing historical traffic accident data and road network structural characteristics. This prioritizes accident-prone sections, sharp bends and steep slopes, tunnel entrances and exits, and overpasses. Traffic flow distribution characteristics are then combined to determine the optimal deployment locations for analysis and identification units. A standardized pole structure is established at each monitoring point, using adjustable brackets for mounting equipment to ensure complete coverage of the target area.
[0075] This embodiment performs comprehensive parameter initialization and configuration for the edge box. First, basic device parameters are set, including processor frequency, memory allocation, and storage policy. The network configuration uses a dual-link redundant design, supporting both wired and 4G / 5G wireless networks to ensure communication reliability. The edge box obtains a unique hardware-based identification code through the IoT communication module. This identification code is combined with geographic location information and device type to generate a globally unique device ID.
[0076] This embodiment designs a secure device registration mechanism.

After receiving the registration request, the cloud platform verifies the legitimacy of the device identity and allocates resource quotas. Registration authorization information includes access tokens, encryption keys, service configuration, and other information. Based on this authorization information, the edge box establishes a TLS encrypted channel for secure communication with the cloud platform.
[0077] This embodiment achieves precise calibration of smart cameras. The license plate capture camera uses a two-axis pan-tilt mount, automatically adjusting the shooting angle and focal length through an image quality assessment algorithm. The calibration process uses standard test license plates, collects image samples under different lighting conditions, and optimizes image processing parameters. The wide-angle camera uses a specialized calibration plate, establishing an image coordinate system through corner detection and spatial mapping.
[0078] This embodiment builds a device management system based on edge boxes. The edge boxes serve as local control centers, connecting to smart cameras and environmental monitoring equipment via industrial Ethernet. Devices use a master-slave communication architecture, with the edge boxes periodically sending heartbeat packets to sub-devices to check their online status. If a device anomaly is detected, the system automatically switches to a backup communication link to ensure continuous data collection.
[0079] This embodiment optimizes the configuration strategy for environmental monitoring equipment.

The cloud platform returns a device authorization code, and the vehicle-mounted module establishes a data transmission channel with the cloud platform based on the device authorization code. The vehicle-mounted module uses the vehicle-mounted CAN bus interface to collect the vehicle's real-time position coordinates, driving speed, and direction angle data;
[0085] Step S302: The on-board module uploads the position coordinates, driving speed and direction angle data to the cloud platform at preset time intervals. The cloud platform maps the vehicle position coordinates to an electronic map based on a geographic information system, determines a forward predicted path according to the vehicle's driving direction, extracts the analysis and identification units within the coverage of the predicted path, constructs the extracted analysis and identification units into a regional linkage network, and assigns a network priority to each of the analysis and identification units.

A local caching mechanism is also implemented, temporarily storing data during network interruptions and automatically retransmitting it upon network recovery.
[0091] This embodiment innovatively designs a location mapping algorithm. The cloud platform utilizes high-precision electronic maps and a multi-level indexing structure to rapidly locate the vehicle's current road section. This location mapping takes into account road geometry and traffic regulations, accurately identifying the vehicle's lane. Based on historical trajectory data and current heading angle, a Kalman filter algorithm is used to predict the vehicle's future path, with the prediction range dynamically adjusted based on vehicle speed.
[0092] This embodiment builds an adaptive regional linkage network. The cloud platform extracts relevant analysis and identification units based on the predicted path and constructs a directed acyclic graph using graph theory algorithms. Nodes in the graph represent analysis and identification units, and edges represent the relationships between units. Network priority assignment takes into account multiple factors, including distance from the predicted path, road grade, and historical accident frequency. Priority values are calculated through weighted calculations and used for subsequent linkage triggering decisions.
[0093] This embodiment implements dynamic updates to the network topology. As vehicle locations change, the cloud platform adjusts the coverage of the regional linkage network in real time. Using a sliding window mechanism, analysis and identification units that are about to enter the predicted path are added to the network in advance, while units that have already left the path are removed. This dynamic adjustment mechanism ensures that the network structure always stays synchronized with the vehicle's travel path.
[0094] Through the above technological innovations, this embodiment effectively addresses the challenges of traditional on-board device management and path prediction.

[0096] Step S401: The license plate capture camera collects image data of a vehicle passing by. The edge box processes the image data based on a convolutional neural network model, extracts license plate area features and performs character segmentation, identifies the license plate number and color information, analyzes the vehicle body contour features through a deep learning model to obtain a vehicle model classification result, and stores the license plate number, color information, and vehicle model classification result in a cache database of the edge box.
[0097] Step S402: The wide-angle camera collects road traffic video streams at a preset frame rate. The environmental detection equipment obtains visibility values based on the laser ranging principle and detects road surface state parameters through surface temperature sensors and humidity sensors. The edge box performs target detection and tracking processing on the video stream, extracts driving characteristic parameters such as vehicle trajectory, vehicle speed, and vehicle spacing, and establishes a mapping relationship between the driving characteristic parameters and license plate information.
[0098] Optionally, this embodiment employs a multi-stage processing strategy for license plate recognition. First, the license plate capture camera uses adaptive exposure technology, dynamically adjusting exposure parameters based on ambient lighting conditions to ensure image quality. When a vehicle enters the field of view, high-speed capture is triggered, capturing multiple frames of image data. A motion compensation algorithm is then used to select the clearest image for processing.
[0099] This embodiment designs an improved license plate detection network. The convolutional neural network model, built on the YOLOv5 framework, employs a multi-scale feature fusion strategy to enhance detection capabilities for license plates at varying distances. A spatial pyramid pooling module is incorporated into the network structure to enhance adaptability to license plate deformation and tilt. The model is trained using a dataset of license plate images under various lighting and weather conditions to improve generalization.
[0100] This embodiment implements a precise character segmentation algorithm. It uses an improved FCN semantic segmentation network to achieve pixel-level segmentation at the character level. By introducing an attention mechanism, the ability to distinguish similar characters is improved. During the character recognition stage, a deep residual network is used in conjunction with the CTC loss function to improve recognition accuracy. Furthermore, color histogram analysis is used to determine the base color of the license plate, enabling accurate classification of the license plate type.

A deep learning model extracts vehicle body contour features, including key features such as aspect ratio, front shape, and window layout. A multi-task learning framework is employed to simultaneously predict vehicle type, make, and model, improving classification accuracy. The model also employs a transfer learning strategy, leveraging pre-trained models to accelerate training convergence.
[0102] This embodiment builds an efficient cache database. It uses a key-value storage structure, with the license plate number as the primary key, to store vehicle-related feature information. The database supports concurrent access and transaction processing to ensure data consistency. It manages in-memory data using a least-repeated (LRU) cache strategy, automatically clearing the least recently accessed records when capacity is exceeded.
[0103] This embodiment optimizes the video stream processing process. The wide-angle camera uses a 25 frames per second sampling rate and implements video compression through a hardware encoder. The edge box utilizes a multi-threaded parallel processing architecture to simultaneously process multiple video streams. Object detection utilizes an improved DeepSORT algorithm to achieve stable vehicle tracking. A projection transformation establishes a mapping between pixel coordinates and actual distances to calculate the vehicle's actual position and speed.
[0104] This embodiment implements intelligent collection of environmental parameters. A laser ranging device calculates visibility by measuring the attenuation of the laser signal, with the sampling period dynamically adjusted based on the rate of weather change. A surface sensor array uses thermocouples to measure road surface temperature distribution and, combined with humidity data, determines road surface conditions, such as dryness, dampness, waterlogging, and icing.
[0105] This embodiment innovatively establishes a feature mapping mechanism. Using a spatiotemporal correlation algorithm, a correspondence is established between vehicle tracking trajectories and license plate information. This algorithm considers the continuity of vehicle motion and physical constraints, effectively addressing correlation issues in situations with occlusion and dense traffic. For vehicles that temporarily lose their license plate information, trajectory prediction is used to maintain tracking.
[0106] This embodiment designs a feature parameter extraction method. Based on the tracked trajectory, it calculates vehicle kinematic characteristics, including instantaneous velocity, acceleration, and steering angular velocity. It also calculates the distance between vehicles and their relative speeds based on the positional relationships of adjacent vehicles to assess potential collision risks. All feature parameters undergo data smoothing and outlier filtering to ensure data quality.
[0107] Through the above technological innovations, this embodiment overcomes the limitations of traditional traffic monitoring systems in vehicle identification and behavior analysis. In practical applications, this solution accurately identifies vehicle characteristics and tracks vehicle movement in real time, providing reliable data support for traffic flow prediction and risk assessment. The system maintains stable identification and tracking performance, particularly under complex road conditions and inclement weather, significantly improving the accuracy and reliability of traffic monitoring.
[0108] In one embodiment of the vehicle driving intelligent control method of the present application, the following contents may also be specifically included:
[0109] Step S501: The edge box divides the vehicle driving characteristic parameters into a training data set according to the time series, uses a long short-term memory neural network to construct a network structure of a traffic flow prediction model, uses vehicle speed, vehicle density, and travel time as input features, iteratively trains the network structure to obtain a traffic flow prediction model, and constructs a risk assessment model based on a decision tree algorithm, using vehicle spacing, relative speed, and road surface state parameters as input variables to calculate a collision risk assessment value;
[0110] Step S502: The edge box organizes the vehicle driving characteristics, environmental parameters and timestamp information into a data packet, which contains the future traffic flow state prediction results output by the traffic flow prediction model and the risk assessment value calculated by the risk assessment model. The edge box sends the data packet to the cloud platform through a secure communication link according to a preset data upload cycle, and the cloud platform performs time synchronization and data verification on the received data packet.
[0111] Optionally, this embodiment innovatively designs a data preprocessing process. The edge box uses a sliding window mechanism to organize continuously collected vehicle driving features into training samples in chronological order. The window size is dynamically adjusted based on the prediction time span, for example, using a 5-minute window for short-term predictions and a 15-minute window for medium-term predictions. During the data preprocessing phase, feature scaling is unified using maximum and minimum normalization, and median filtering is used to remove outliers.
[0112] This example builds a traffic flow prediction model based on a long short-term memory (LSTM) network. The network structure consists of an input layer, an LSTM layer, a fully connected layer, and an output layer. Input features include three key indicators: vehicle speed, vehicle density, and travel time. These indicators comprehensively reflect road traffic conditions. The LSTM layer uses a gating mechanism to capture long-term dependencies in time series data. The forget gate filters out irrelevant information, and the input and output gates control information updates and outputs.
[0113] This embodiment optimizes the model training strategy. Batch gradient descent is used for parameter optimization, and the learning rate is adaptively adjusted. A higher learning rate is used for rapid convergence in the early stages of training, and a gradually reduced learning rate is used for fine-tuning. To prevent overfitting, a dropout layer is introduced to randomly discard some neurons, and L2 regularization is used to constrain model parameters. The loss function uses mean squared error, and the backpropagation algorithm is used to calculate gradients and update parameters.
[0114] This embodiment implements a risk assessment model based on a decision tree. A binary decision tree is constructed using the CART algorithm, with input variables including vehicle spacing, relative speed, and road surface condition parameters. The decision tree's splitting criterion uses the Gini index, recursively selecting the optimal splitting feature and threshold. The predicted value of a leaf node represents the collision risk probability, ranging from 0 to 1. The model is trained using labeled historical accident data, and the optimal tree depth is determined through cross-validation.
[0115] This embodiment innovatively designs a risk assessment method. The risk assessment value R is calculated using the following formula:
[0116] R = w1 D + w2 V + w3 S
[0117] Where D is the normalized vehicle spacing, V is the relative speed, S is the road surface condition coefficient, and w1, w2, and w3 are weighting factors. The weighting factors are determined through historical data analysis and reflect the impact of each factor on safety risk. A risk warning is triggered when the R value exceeds a preset threshold.
[0118] This embodiment optimizes the data packet structure. It employs a layered design: the bottom layer contains basic data fields, including device ID, timestamp, and location coordinates; the middle layer contains feature data fields, including vehicle driving characteristics and environmental parameters; and the top layer contains analysis result fields, including traffic flow prediction results and risk assessment values. Data packets are encoded in a compact binary format to reduce transmission overhead.
[0119] This embodiment implements an intelligent data upload strategy. Under normal circumstances, data packets are uploaded at a fixed interval, which can be dynamically adjusted based on network conditions. When an abnormality is detected, such as a sudden increase in risk assessment values or a dramatic change in traffic flow as indicated by forecast results, a real-time upload mechanism is triggered. Data transmission utilizes the TLS encryption protocol to ensure data security.
[0120] This embodiment designs a data synchronization and verification mechanism. After receiving a data packet, the cloud platform first checks the timestamp consistency and reorders packets that arrive out of order. Data integrity is verified using a CRC checksum, and packets that fail verification are requested to be retransmitted. A clock synchronization mechanism is also implemented to ensure time consistency between the edge box and the cloud platform.
[0121] Through the above technological innovations, this embodiment addresses the problems of low prediction accuracy and inaccurate risk assessments that plague traditional traffic prediction systems. In practical applications, this solution can accurately predict traffic flow trends and promptly identify potential safety risks. Especially in complex road conditions, the system can comprehensively analyze multi-dimensional data, providing a reliable basis for traffic management decisions and effectively improving road safety and efficiency.
[0122] In one embodiment of the vehicle driving intelligent control method of the present application, the following contents may also be specifically included:
[0123] Step S601: The cloud platform receives data packets uploaded by multiple analysis and identification units, extracts the risk assessment value, traffic flow, speed and other indicator parameters from the data packets, and compares the indicator parameters with thresholds in the road traffic strategy, which includes a traffic flow density threshold, an average speed threshold, and a unit mileage accident risk threshold. When the indicator parameters of any analysis and identification unit exceed the corresponding threshold, a regional linkage judgment is triggered, and the cloud platform determines the affected range based on the location of the analysis and identification unit that triggered the linkage;
[0124] Step S602: The cloud platform selects the analysis and identification unit located within the affected range from the regional linkage network as a linkage object, generates a linkage session including a linkage object identification code, creates a data sharing channel based on the linkage session, sends a linkage instruction including sharing channel configuration information to the linkage object, receives a confirmation response returned by the linkage object through the data sharing channel, and completes the establishment of a communication link between the linkage objects.
[0125] Optionally, this embodiment implements an intelligent data processing process. The cloud platform uses a distributed message queue to receive data packets uploaded by multiple analysis and recognition units, and uses message middleware to achieve reliable data transmission and load balancing. Upon arrival, the data packets are first parsed and verified, extracting key indicator parameters such as risk assessment value, traffic volume, and average speed. These parameters are then cleaned and standardized to ensure data consistency.
[0126] This embodiment designs an adaptive threshold judgment mechanism. The threshold in the road traffic strategy is not fixed, but is dynamically adjusted based on road grade, time characteristics and historical data. The traffic flow density threshold D is calculated by the following formula:
[0127] D = Dbase (1 + k1 T + k2 W)
[0128] Where Dbase is the base density threshold, T is the time period coefficient, W is the weather impact coefficient, and k1 and k2 are adjustment factors. This dynamic threshold mechanism can better adapt to the needs of different scenarios.
[0129] This embodiment innovatively implements a regional linkage judgment algorithm. When an indicator parameter of a specific analysis and identification unit exceeds a threshold, the system calculates the impact range based on a traffic flow propagation model. This propagation model considers factors such as road network topology, traffic flow direction, and propagation speed. A graph theory algorithm analyzes road network connectivity and identifies potentially affected associated road sections. The impact range is calculated using a spatiotemporal diffusion model, with the size of the range positively correlated with the degree and duration of the violation.
[0130] This embodiment establishes an efficient linkage target selection mechanism. The cloud platform extracts analysis and identification units within the affected area from a pre-established regional linkage network and screens them based on priority and location. The selection process considers multiple dimensions, including device performance, network status, and historical reliability, to ensure the most appropriate linkage targets. A backup mechanism is also implemented, configuring backup devices for key nodes to improve system reliability.
[0131] This embodiment optimizes the linkage session management process. Each linkage session is assigned a globally unique session ID, which contains information such as trigger conditions, participants, and validity period. Session management utilizes a distributed architecture, supporting parallel processing of multiple sessions. A state machine mechanism manages the session lifecycle, ensuring controllable and traceable session creation, maintenance, and release processes.
[0132] This embodiment designs a reliable data sharing channel. A full-duplex communication link is established based on the WebSocket protocol, supporting real-time data push and command issuance. Channel configuration adopts a hierarchical design, including basic and extended configurations. The basic configuration ensures basic channel connectivity, while the extended configuration is dynamically loaded based on business needs. Channel creation uses a handshake mechanism to ensure that all participants reach consensus on communication parameters.
[0133] This embodiment implements an intelligent command issuance strategy. Linked commands are processed according to priority, with urgent commands prioritized. The command format utilizes a unified protocol specification, including fields such as command type, parameter configuration, and execution time. Reliable command transmission is achieved through a message queue mechanism, supporting command confirmation and retransmission. Real-time monitoring of command execution status is also implemented, enabling timely detection and resolution of anomalies.
[0134] This embodiment establishes a complete confirmation and response mechanism. After receiving a command, the linked object first verifies its legitimacy and integrity. It then evaluates the command's feasibility based on local resource availability and generates a response message containing an execution plan. This response message is returned to the cloud platform via a data sharing channel, which confirms the establishment of the linkage relationship. For devices that fail to respond in a timely manner, a timeout mechanism is triggered.
[0135] Through the above technological innovations, this embodiment addresses the issues of delayed regional coordination and low coordination efficiency in traditional traffic management systems. In practical applications, this solution enables rapid response to traffic anomalies and establishes an efficient device coordination mechanism. Especially in emergencies such as traffic accidents and severe weather, the system can quickly coordinate the response of relevant devices, providing strong support for traffic diversion and safety warnings, significantly enhancing the level of intelligent road traffic management.
[0136] In one embodiment of the vehicle driving intelligent control method of the present application, the following contents may also be specifically included:
[0137] Step S701: The cloud platform receives the traffic flow prediction results uploaded by the linkage object, maps the traffic flow prediction results to road sections based on real-time location coordinates, calculates the congestion index of each road section, and calls the path planning engine to calculate the shortest path and the optimal detour path. The cloud platform inputs the lane-level traffic condition information, the road section congestion index, the average travel speed, and the travel time into the warning information generation model, calculates the recommended safe speed based on the vehicle type and road conditions, and generates warning text content.
[0138] Step S702: The cloud platform extracts the license plate information from the cache database of the linkage object, establishes a corresponding relationship between the warning text content and the license plate information, and generates a warning message containing an addressing identifier. The cloud platform queries the communication address of the on-board module and sends the warning message to the corresponding on-board module through the message queue. After receiving the warning message, the on-board module calls the speech synthesis engine to broadcast it and displays the warning content on the car screen.
[0139] Optionally, this embodiment implements an intelligent traffic flow analysis mechanism. After receiving the prediction results uploaded by the linked objects, the cloud platform first performs a spatiotemporal consistency check to ensure the validity of the data. The prediction results are mapped to specific road sections using a high-precision electronic map, establishing a correlation between the prediction data and the road network topology. The congestion index CI is calculated using the following formula:
[0140] CI = (V0 - V) / V0 (ρ / ρmax)
[0141] Where V0 is the free flow speed, V is the current average speed, ρ is the current traffic density, and ρmax is the maximum traffic density. This index comprehensively reflects the road traffic status.
[0142] This embodiment optimizes the path planning algorithm. The algorithm searches for the shortest path, using the congestion index as a weighting factor for road sections and dynamically adjusting path evaluation criteria. When calculating the optimal detour, it comprehensively considers factors such as distance increment, time increment, and road reliability. Using a multi-objective optimization approach, it selects the optimal solution from multiple candidate paths, ensuring the practicality of the detour recommendations.
[0143] This embodiment innovatively designs a warning information generation model. The model utilizes a deep neural network architecture, with input features including multi-dimensional data such as lane-level road conditions, congestion index, and average speed. An attention mechanism identifies key information and generates warning text that aligns with human cognitive habits. The model is trained using a large amount of real-world scenario data to ensure the accuracy and comprehensibility of the generated content.
[0144] This embodiment implements an intelligent safe speed calculation method. A baseline speed is set based on vehicle type and dynamically adjusted based on environmental factors such as road curvature, slope, and weather conditions. Additional speed constraints are introduced in special sections of road, such as construction zones and school areas. The system also considers safety factors such as following distance and braking distance to ensure the recommended speed meets safety requirements.
[0145] This embodiment establishes an efficient vehicle information management mechanism. The cloud platform maintains a distributed cache database that stores the mapping between license plate information and onboard modules. A multi-level caching strategy keeps hot data in memory, improving query efficiency. The database supports real-time updates, ensuring the timeliness of vehicle information. A data synchronization mechanism ensures data consistency across all nodes.
[0146] This embodiment optimizes the organizational structure of warning messages. Warning messages consist of multiple layers: a metadata layer containing basic information such as the message ID, timestamp, and priority; a content layer containing specific information such as road conditions, detour suggestions, and recommended speeds; and a control layer containing presentation parameters such as broadcast strategies and display styles. A compact serialization format is used to reduce transmission overhead.
[0147] This embodiment designs a reliable message delivery mechanism. The cloud platform implements asynchronous transmission of warning messages through a message queue system, supporting message priority management and retry upon failure. A push-pull approach is employed, with urgent messages proactively pushed and common messages allowed to be periodically retrieved by the onboard module. A heartbeat mechanism monitors communication status to ensure message delivery.
[0148] This embodiment implements an intelligent broadcast control strategy. Upon receiving a warning message, the onboard module first analyzes the message's priority and timeliness. Urgent warnings are immediately interrupted for an interruption, while standard warnings are broadcast at an appropriate time. Speech synthesis utilizes a deep learning model to generate natural and fluent voice prompts. Key information is also prominently displayed on the vehicle's screen.
[0149] This embodiment optimizes information presentation through a dynamic display strategy. The screen uses a partitioned layout, placing important information prominently. Key prompts are enhanced through animation, such as dynamic arrows for detours. The display automatically adjusts information density based on vehicle speed, ensuring the driver can quickly access critical information.
[0150] Through the above technological innovations, this embodiment addresses the issues of limited information targeting and low transmission efficiency in traditional warning systems. In practical applications, this solution can provide personalized warning information for different vehicles, helping drivers to promptly understand road conditions and make informed decisions. Especially in complex road conditions and emergency situations, the system delivers warning information promptly through multiple channels, effectively improving road safety and efficiency and significantly enhancing the driver's travel experience.
