With the continuous advancement of technology and the improvement of regulations, the safety of intelligent driving will be further improved.
[0003] Currently, in terms of driving safety, trucks are large in size and have many blind spots.

Therefore, when driving on complex roads, blind spots may lead to dangerous incidents, especially at intersections, where pedestrians and non-motor vehicles may seize space, and cars may illegally overtake. The safety factor is extremely low. Summary of the Invention

[0065] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0066] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script without departing from the scope of this application.
[0067] Figure 1 A flowchart of an intelligent driving safety assistance management method provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes:
[0068] S100 collects real-time traffic data from the intersection area, identifies whether there are trucks at the current intersection, and identifies the vehicle's location, traffic light status, and movement of other road users;
[0069] This step captures real-time images of the intersection area and uses deep learning algorithms to identify and classify vehicles in the image, particularly trucks. The system also analyzes the vehicle's position, direction, and speed in the image, as well as its relative position to other road users. Image processing technology is used to identify the color and state of traffic lights (red, yellow, green), and edge detection and pattern recognition techniques are used to accurately capture lane markings at intersections, ensuring accurate judgment of the lanes occupied by trucks and other vehicles.
[0070] like Figure 2 As shown, the identification of whether there is a truck vehicle at the current intersection, and the identification of the vehicle location, traffic light status, and movement of other road participants specifically include:
[0071] S110, analyzing the image collected by the intersection monitoring equipment, extracting image features, and identifying whether there is a truck type vehicle;
[0072] S120 captures the status of traffic lights and lane markings at intersections in real time, and analyzes the lanes and current positions of trucks and other road users.
[0073] S200 predicts the truck's trajectory in real time based on the truck's lane, headlight status, speed data, and traffic light status at the intersection, and determines the truck's blind spots within the trajectory;
[0074] This step first determines the truck's driving intention, such as whether it is about to turn, change lanes, or stop, by analyzing the truck's lane, traffic light status, and the truck's headlights (such as turn signals and brake lights). Furthermore, by combining the truck's speed and acceleration data, the system can more finely infer its driving intention, ensuring accurate predictions. The system then uses a machine learning model, combined with historical data and current real-time traffic conditions, to predict the truck's possible trajectories under different driving intentions. Taking into account the truck's size, weight, and inertia, the system accurately predicts the truck's trajectory. Furthermore, the system conducts in-depth analysis of the captured images to identify the truck's specific size and shape. Combined with previously predicted truck trajectories, it determines potential blind spots during the truck's travel. These blind spots include those in front of the truck, especially when turning or changing lanes; those on the sides of the truck, especially when merging or negotiating narrow roads; and those behind the truck, especially when slowing down or stopping.
[0075] By comprehensively analyzing a truck's driving intentions, predicted trajectories, and identified blind spots, the system can more accurately predict the truck's path and potential risks, thereby improving road traffic safety. The system utilizes advanced machine learning models and image analysis technology, enabling it to adapt to complex and changing traffic environments, significantly enhancing the intelligence level of intelligent driving safety assistance management. Furthermore, the system's real-time data processing and rapid prediction capabilities ensure rapid response to traffic changes, prompt warnings, and timely decision-making to effectively prevent traffic accidents. These advantages collectively ensure that this intelligent driving safety assistance management method can more effectively prevent and reduce traffic accidents in practical applications, thereby improving overall road traffic safety and operational efficiency.
[0076] like Figure 3 As shown, the real-time prediction of the truck's driving trajectory and the determination of the truck's visual blind spot within the driving trajectory specifically include:
[0077] S210, judging the driving intention of the truck based on the lane the truck is in, the state of the traffic light, and the state of the truck's lights, and obtaining a predicted trajectory result of the truck;
[0078] S210: Analyze the collected images, identify the size of the truck, and, based on the truck trajectory prediction results, determine the potential blind spots of the truck during driving. Specifically:
[0079] Front blind spot:
[0080] Left and right blind spots:
[0081] Rear Blind Distance = L v ;
[0082] Among them, W v Indicates the width of the truck, L v Indicates the length of the truck, FOV h Indicates the horizontal field of view of the camera, D r represents the distance from the front of the truck to the camera, and θ represents the angle between the camera chamber and the horizontal angle.
[0083] S300, based on the truck's trajectory and real-time road dynamics, and matching the locations and behavior patterns of other road users, performs overlap detection on the predicted possible driving paths. If other road users are in the truck's blind spot, collision risk is identified.
[0084] In this step, all road users, including but not limited to pedestrians, cyclists, motorcycles, and other vehicles, are identified and tracked. Using high-precision sensors and advanced image recognition technology, the system captures and analyzes the positions and movements of these users in real time. The system then integrates the predicted trajectories of the truck and other road users, as well as any potential blind spots in the truck's field of view, to conduct a comprehensive collision risk assessment.
[0085] Specifically, a point-in-polygon detection algorithm is used to determine whether each road user's current position lies within the truck's blind spot polygons. This algorithm accurately determines whether other road users are within the truck's blind spot. The system also calculates the relative distances between the truck and other road users at any given moment, further assessing collision risk based on the truck's dimensions and the collision radius of the other road users. If a road user is within the truck's blind spot and their relative distance to the truck is less than or equal to the sum of their collision radii, the system determines a potential collision exists.
[0086] By integrating the truck's trajectory, blind spots, and the real-time location and behavior patterns of other road users, the system effectively prevents potential traffic accidents. The system processes and analyzes large amounts of traffic data in real time, rapidly responding to dynamic changes on the road and promptly detecting and warning of potential collision risks, achieving comprehensive safety coverage for the entire transportation system. Furthermore, based on advanced algorithms and data analysis technologies, the system provides intelligent decision-making support, helping traffic managers more effectively dispatch traffic and manage safety. This provides efficient and accurate safety assurance in complex traffic environments, significantly improving the safety and smoothness of road traffic.
[0087] like Figure 4 As shown, the predicted possible driving paths are overlapped and detected. If there are other road users in the truck's blind spot, the collision risk is identified, specifically including:
[0088] S310, identifying and tracking the position and movement trajectory of road participants;
[0089] S330 integrates the trajectory prediction results of the truck and other road users, and considers the potential blind spots of the truck during driving to assess the potential blind spot collision risk. Specifically:
[0090] Use the point-in-polygon detection algorithm to determine the current position P of the road participant B (t) Whether it is inside the blind spot polygons of the truck, so as to check the current position P of other road participants B B (t) Whether it is in the blind spot of truck A;
[0091] Calculate the relative distance d(t) between truck A and other road participants B at any given time t:
[0092]
[0093] Among them, (P A (t) x , P A (t) y ) represents the position coordinates of truck A at time t, (P B (t) x , P B (t) y ) represents the position coordinates of other road participant B at time t;
[0094] If P B (t) is in the blind spot, and the relative distance d(t) is less than or equal to the sum of the collision radius R of the truck A and other road participants B. A +R B , it means there is a collision event;
[0095]
[0096] S400, generating warning information for different road participants and using traffic lights and electronic display screens to warn other traffic participants;
[0097] This step generates alerts tailored to different road users based on the identified collision risk. These alerts are intended to promptly notify and warn potentially affected pedestrians, cyclists, motorcyclists, and other drivers. The system customizes the content and format of these alerts based on the risk level and the affected parties, ensuring effective communication and reception.
[0098] Specifically, the system will issue warning information through various channels, including but not limited to the flashing changes of traffic lights, real-time updates of electronic display screens at intersections, voice prompts from on-board devices, push notifications from mobile applications, etc. For example, for pedestrians, the system may guide them to pay attention to safety through pedestrian lights and ground LED indicators at intersections; for cyclists and motorcycle riders, the system may issue sound or vibration warnings through their smart helmets or on-board devices; for other vehicle drivers, the system may alert them to potential collision risks through specific flashing patterns of traffic lights or warning prompts from the on-board navigation system.
[0099] S500, real-time traffic data of the intersection is collected again to determine whether a collision event occurs, and if so, an automatic alarm is issued.
[0100] This step further collects real-time traffic data at the intersection to monitor and determine if a collision has occurred. This step ensures real-time monitoring of traffic conditions at the intersection through continuous data collection and analysis. The system pays special attention to the movements of the truck and other road users in its blind spot, as well as changes in traffic light status, to accurately determine if a collision has occurred.
[0101] Specifically, the system utilizes high-precision sensors and advanced image recognition technology to capture real-time traffic conditions at intersections. By comparing the previous and subsequent data, the system can identify unusual traffic behavior, such as sudden stops, deviations from the planned trajectory, and signs of vehicle damage, which could indicate a collision. Once the system detects these unusual behaviors, combined with other evidence (such as sudden changes in traffic light status and emergency evasive maneuvers by other road users), it determines that a collision may have occurred.
[0102] Once a collision is detected, the system will automatically execute the alarm procedure and notify the relevant rescue and management departments to ensure timely handling of the accident and reduce the risk of secondary injuries.
