[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In modern traffic environments, horns are the most commonly used warning tool for vehicles, used to remind surrounding vehicles or pedestrians to pay attention and avoid. However, the use of horns has caused widespread noise pollution to a certain extent, especially in places that are sensitive to sound environments such as residential areas, schools and hospitals. Frequent and high-decibel horn sounds have seriously affected the quality of life and working environment of residents. In order to reduce noise pollution, some areas have promoted measures to reduce the volume of horns or prohibit the use of horns, but this has also brought new problems. Reducing the sound of horns may lead to a significant decrease in the warning effect, especially in noisy urban environments. Low-volume horns often fail to attract the attention of other road users. In emergency situations, such as reminding pedestrians or vehicles to avoid, too low a volume may increase the risk of accidents and fail to fully play the warning function.

[0024] At the same time, the role of light warnings and signs in dynamic traffic scenes is also limited. Light warnings are less effective during the day and are difficult to be clearly identified in high-light environments, while signs can only provide static instructions and cannot be dynamically adjusted according to real-time traffic conditions. These traditional warning methods are powerless in multi-lane, high-volume and complex traffic environments and are difficult to meet the needs of modern road safety.

[0025] In view of the above problems, an embodiment of the present invention provides a driving warning method. The execution subject of the method is a vehicle that sends warning information. In the embodiment of the present invention, the vehicle that sends the warning information is regarded as the local vehicle. Figure 1 This is one of the flow charts of the driving warning method provided by the present invention. Figure 1 As shown, the method includes: Step 110, obtaining driving information of surrounding vehicles.

[0026] Specifically, the on-board system uses hardware such as cameras and radars (such as millimeter-wave radars and lidars) to collect the operating status of surrounding vehicles on the current road in real time, including but not limited to parameters such as the speed, direction, position, and acceleration of each surrounding vehicle.

[0027] In addition, through vehicle networking technologies (such as V2X communication technology), vehicles can also obtain driving information from other connected surrounding vehicles. For example, V2X communication technology uses radio services in the 5.850 to 5.925 GHz frequency band to obtain driving information of surrounding vehicles in a low-latency and high-reliability manner.

[0028] The information collection process needs to ensure the real-time and accuracy of the information to support the subsequent analysis of collision risks and the generation of warning information.

[0029] Step 120: determining a warning vehicle from the surrounding vehicles based on the driving information of the surrounding vehicles.

[0030] The local vehicle analyzes the driving information of surrounding vehicles and determines the target vehicles with potential collision risk with the local vehicle in real time, thereby determining the warning vehicle. Specifically, based on the driving information of the vehicle, such as position, speed, direction and other parameters, combined with the calculation of the relative distance and relative speed between the local vehicle and the surrounding vehicles, it determines whether the two vehicles are likely to collide.

[0031] On this basis, in order to improve the comprehensiveness of collision risk judgment, the actual conditions of the current road can also be comprehensively considered, such as lane width, traffic density, and the distribution of surrounding obstacles. These environmental factors have an important impact on risk assessment and can help more accurately determine whether surrounding vehicles are warning vehicles. Through comprehensive analysis, not only can misjudgment be avoided, but also unnecessary interference can be reduced, ensuring the pertinence and reliability of the warning.

[0032] Through the above method, it is possible to accurately judge and effectively warn of the potential collision risk of surrounding vehicles. This method based on driving information analysis can significantly improve the safety of vehicles in complex traffic environments, while enhancing the accuracy and real-time nature of warnings, and effectively reducing the possibility of misjudgment and missed judgments.

[0033] Step 130: Send warning information to the warning vehicle, where the warning information is used to trigger a driving reminder inside the warning vehicle.

[0034] Specifically, the warning information includes the driving information of the vehicle that sends the warning information, such as the current position, driving speed and driving direction of the vehicle; and the relative driving information between the local vehicle and the warning vehicle, such as the relative position and relative speed between the two vehicles. The driving information of the sending end can clearly describe the state of the local vehicle in the traffic flow. The relative driving information further refines the driving relationship between the local vehicle and the warning vehicle. In addition, the warning information may also contain supplementary data for risk analysis, such as the predicted collision time window or information about other traffic participants that may be involved in the target area. This information can be generated through a dynamic analysis model, providing a higher-dimensional judgment basis for the on-board system of the warning vehicle. The combination of these data can not only reveal the current risk status, but also provide important dynamic feedback to the driver, helping him to judge the severity of the potential collision risk and make corresponding operational judgments.

[0035] Warning information can be transmitted using a variety of technical means, such as real-time transmission through vehicle networking communication modules (such as V2X communication), short-range wireless communication technology (such as DSRC) or cellular network technology (such as C-V2X). These technologies can ensure low latency and high reliability of information transmission. At the same time, according to the needs of specific scenarios, they can also be sent in combination with local broadcast or multicast to adapt to different traffic conditions and communication environments. Encryption mechanisms and data verification methods can also be used in the transmission process to ensure the accuracy and security of information.

[0036] After the warning vehicle receives the warning information, the on-board system can parse the warning information and generate corresponding prompts. Driving prompts come in various forms, such as audio reminders, visual warnings, or a combination of the two. For example, when the warning vehicle is at potential risk of collision, the in-car sound effects will simulate the direction of the source of danger through directional warning sounds, and the relative position of the vehicle on the other end and the estimated collision time will be displayed in the form of an image on the dashboard or central control screen. By directly and specifically reminding the driver of the warning vehicle, the interference that the traditional broad warning method may cause to other unrelated vehicles or pedestrians can be avoided, and the accuracy of the reminder can be improved. At the same time, the warning information triggers driving prompts in the warning vehicle, which helps the driver perceive potential risks more quickly, reduce reaction time, and improve driving safety.

[0037] The driving warning method provided by the present invention avoids the problem of horn noise pollution and weakening the warning effect by reducing the volume by accurately sending warning information to the warning vehicle and triggering driving prompts in the vehicle. The method adopts directional reminders and only targets vehicles that may collide, which improves the accuracy and effectiveness of the warning. At the same time, it overcomes the poor effect of light warnings during the day and the shortcomings of static information on billboards, and can realize real-time risk warnings in complex traffic scenes, significantly improving driving safety and environmental friendliness.

[0038] Based on the above embodiment, in step 120, determining the warning vehicle from the surrounding vehicles based on the driving information of the surrounding vehicles includes: Based on the driving information of the surrounding vehicles, a vehicle collision warning is provided to the surrounding vehicles; Based on the collision warning results of the surrounding vehicles, a warning vehicle is determined from the surrounding vehicles.

[0039] Specifically, by analyzing the driving information of each surrounding vehicle, including its current position, speed, driving direction and acceleration, as well as the relative position and speed difference with the local vehicle, it is determined whether there is a risk of collision between the two vehicles. The time to collision (TTC) is used as a key indicator, and the threshold is set in combination with the safe stopping distance (0.5 meters to 3 meters). The time to collision indicates the event that the two vehicles may collide while maintaining the current speed or acceleration and direction unchanged.

[0040] Next, based on the collision warning results, the warning vehicle is determined from the surrounding vehicles. Specifically, when the collision time of a surrounding vehicle is lower than the preset threshold, the vehicle is considered to have a collision risk and is marked as a warning vehicle. The collision time reflects the time window in which the local vehicle and the surrounding vehicles may collide while maintaining the current driving state. By comparing with the threshold, it can quickly determine whether the vehicle poses a potential threat to the local vehicle.

[0041] This screening mechanism can effectively reduce the interference of irrelevant vehicles, while ensuring that the selection of warning vehicles is accurate and reliable, laying the foundation for subsequent directional information transmission. This process not only enhances the efficiency of driving warning, but also improves the risk identification ability in complex traffic environments.

[0042] Based on the above embodiment, the vehicle collision warning for the surrounding vehicles based on the driving information of the surrounding vehicles includes: Determining the vehicle state of the surrounding vehicles based on the vehicle speed in the driving information of the surrounding vehicles; Based on at least one of the relative distance, vehicle speed and vehicle acceleration in the driving information of the surrounding vehicles, at least one of the vehicle speed and vehicle acceleration of the local vehicle, and the vehicle status of the surrounding vehicles, a vehicle collision warning is provided to the surrounding vehicles.

[0043] Specifically, the vehicle status of the surrounding vehicles includes different states such as constant speed, deceleration or stationary. This state information lays an important dynamic foundation for the subsequent collision risk assessment. Next, the possibility of collision between the two vehicles is analyzed by calculating the collision time, combining at least one parameter of the relative distance, speed and acceleration of the surrounding vehicles and at least one parameter of the speed and acceleration of the local vehicle.

[0044] As an important indicator for determining collision risk, collision time is used to describe the time window in which a collision may occur when two vehicles maintain their current speed and direction. Before calculating the collision time, the relative distance between the surrounding vehicles and the vehicle at the end needs to be calculated. The relative distance can be calculated using the Euclidean distance formula. Specifically, assuming that the coordinates of the vehicle at the end are (X A , Y A ), the coordinates of the surrounding vehicles are (X B , Y B ), the calculation formula of relative distance is: in Indicates the relative distance between the local vehicle and the surrounding vehicles. In addition, the relative distance can also be calculated based on the signal strength of the received signal strength indicator (RSSI). That is, the signal strength decays as the distance increases. According to a specific propagation model (such as the logarithmic distance path loss model), the distance between the sender and the receiver can be estimated. For example, the logarithmic distance path loss model can be expressed as: in, is in the distance The received signal strength at At the reference distance The received signal strength at is an environmental factor, which depends on the impact of the surrounding environment on the signal. Through the above model, the relative distance can be calculated based on the signal strength received by the surrounding vehicles: Combined with the relative distance, the collision time can be calculated based on the speed and acceleration of the local vehicle and the speed and acceleration of surrounding vehicles in the driving information. Specifically, assuming that the relative distance between the two vehicles is s (meters), the safe stopping distance is d (meters), the driving time is t (seconds), and the speed and acceleration of the local vehicle are (m / s) and (m / s 2 ), the speed and acceleration of the surrounding vehicles are (m / s) and (m / s 2 ). When the surrounding vehicles in front are stationary, if: Then no collision will occur. By making both sides of the inequality equal, we can get the collision time at this time: , ( = 0) , ( ≠0) When the surrounding vehicles ahead are moving at a constant speed, if: No collision will occur. By taking the equal sign on both sides of the inequality, we can get the collision time at this time: , ( = 0) , ( ≠0) When the surrounding vehicles in front are decelerating, it is necessary to first determine whether the surrounding vehicles have stopped before the vehicle at the end, and then determine whether a collision will occur before the front vehicle stops. , both cars will stop at the same time. When , the surrounding vehicles stop before the local vehicle, and the travel time of the surrounding vehicles is: At this time, if it satisfies: There will be no collision before the surrounding vehicles stop, and the shortest distance between the two vehicles occurs after the surrounding vehicles stop. The collision time calculation formula is: , ( = 0) , ( ≠0) If satisfied: The shortest distance between two vehicles occurs before the surrounding vehicles stop. After the surrounding vehicles stop, a collision may occur. The calculation formula for collision time is: , ( = 0) , ( ≠0) when When the local vehicle stops before the surrounding vehicles, the shortest distance between the two vehicles occurs before the surrounding vehicles stop. When the speeds of the two vehicles are equal, the collision time calculation formula is: , ( = 0) , ( ≠0) Through the analysis method based on vehicle status, collision time and their motion relationship, it is possible to accurately identify target vehicles with actual risks and provide a reliable basis for the subsequent generation of warning information. This method combines the dynamic characteristics and relative behavior of vehicles, is suitable for complex and changing traffic environments, and greatly improves driving safety and the reliability of the warning system.

[0045] Based on the above embodiment, the driving warning method further includes: Receive the specified operation; In response to the designation operation, a vehicle designated by the designation operation is determined from among the surrounding vehicles as the warning vehicle.

[0046] Specifically, the designated operation refers to the driver or the vehicle system selecting a specific vehicle as a warning target through explicit instructions, which is used to assist or supplement the automated collision warning function in specific scenarios. The designated operation may include the driver manually selecting a vehicle, such as actively marking a surrounding vehicle as a target vehicle through the touch screen, knob or voice command of the vehicle system. This method is usually suitable for complex traffic scenarios, and the driver wants to pay special attention to the dynamic information of a certain vehicle. In addition, the vehicle system can also provide suggestions based on the current traffic conditions. For example, when a vehicle's behavior is detected to be abnormal, such as sudden braking or frequent lane changes, the driver is prompted to set it as a warning vehicle. By responding to these designated operations, the method further screens and marks the selected target vehicles as warning vehicles, enhancing the adaptability and flexibility of the system in complex traffic environments, and providing drivers with more efficient and safe driving support.

[0047] Figure 2 This is the second flow chart of the driving warning method provided by the present invention. The execution subject of the method is the vehicle that receives the warning information. In the embodiment of the present invention, the vehicle that receives the warning information is regarded as the local vehicle. Figure 2 As shown, the method includes: Step 210, receiving warning information, wherein the warning information is sent when the opposite vehicle determines that the local vehicle is a warning vehicle, and the warning vehicle is determined from the surrounding vehicles based on the driving information of the surrounding vehicles of the opposite vehicle; Specifically, the local vehicle receives the warning information through the vehicle-mounted system so as to perceive the potential traffic risks in time. The sending of warning information is based on the comprehensive analysis of the driving information of the surrounding vehicles by the other vehicle, including but not limited to driving information such as relative distance, speed, acceleration, and collision risk assessment results based on collision time and preset thresholds. After the other vehicle determines that the local vehicle may collide with it and marks it as a warning vehicle, the warning information is generated and sent.

[0048] The received warning information not only contains the risk judgment results, but also may contain the absolute driving information of the other vehicle, such as the current position, speed, driving direction, etc. of the other vehicle, as well as the relative driving information between the local vehicle and the other vehicle, such as the relative distance and relative speed of the two vehicles. This information can provide accurate dynamic environmental perception for the local vehicle, allowing the driver to quickly understand the possible sources of risk and their severity. In addition, the warning information can also be combined with the dynamic information of other traffic participants in the target area to provide a more comprehensive traffic risk background.

[0049] By receiving and analyzing the warning information, the local vehicle can take further countermeasures, such as triggering driving prompts or assisted driving systems in the car to help the driver respond quickly. This process ensures that the local vehicle can effectively avoid risks in complex traffic environments and improves overall driving safety.

[0050] Step 220: In response to the warning information, a driving reminder is given in the vehicle.

[0051] Specifically, after receiving the warning information, the local vehicle issues a risk warning to the driver through the vehicle system so that the driver can perceive the possible collision risk in time and take corresponding avoidance measures. This driving warning can be in various forms, including but not limited to sound prompts, visual prompts and multi-modal prompts.

[0052] Audio prompts can be used through the car's speaker system in the form of alarms or voices to remind the driver of the potential risk of collision. Visual prompts can intuitively display relevant information on the car screen. Multimodal prompts are a comprehensive prompt method that combines audio and visual information to ensure that the driver can quickly notice the risk and respond. In addition, the prompt content can also include specific avoidance suggestions, such as reminding the driver to slow down, change lanes or perform emergency braking.

[0053] Through this driving reminder mechanism, the local vehicle can effectively improve the driver's risk perception ability in complex traffic scenarios, shorten the reaction time, and thus significantly reduce the probability of collision accidents. This process not only enhances driving safety, but also provides the driver with a more intuitive and efficient driving experience.

[0054] The driving warning method provided by the present invention can significantly improve driving safety by analyzing vehicle dynamic information in real time and accurately sending warning information to potential collision vehicles. Compared with the defects of traditional horn noise being widely spread and light warning being poor, this method avoids interference with irrelevant vehicles and the environment, and the warning is more targeted and effective. At the same time, by combining absolute driving information and relative driving information, it can accurately judge the risk of collision, and remind the driver in the form of sound or visual effects through in-vehicle driving prompts, shortening the reaction time and reducing the risk of accidents.

[0055] Based on the above embodiment, in step 220, in response to the warning information, providing a driving prompt in the vehicle includes: Based on the warning information, determining the position information of the opposite vehicle relative to the own vehicle; Based on the position information, the opposite vehicle is identified in the surrounding environment image, and / or, based on the position information, the horn sound of the opposite vehicle is directionally simulated.

[0056] First, based on the received warning information, parse and determine the position information of the other vehicle relative to the local vehicle, such as the relative direction, distance and motion status of the other vehicle. These position information can provide the driver of the local vehicle with a clear location of the source of risk, laying the foundation for the subsequent generation of prompt content. Next, based on the position information, the other vehicle can be identified in the surrounding environment image of the local vehicle. For example, in the real-time surrounding environment picture displayed on the on-board display screen, the other vehicle is marked with a specific color or dynamic symbol to intuitively indicate its location and possible collision risk. This method can help the driver quickly identify risk targets and make reasonable driving decisions based on the overall environmental information.

[0057] At the same time, the horn sound of the opposite vehicle can also be simulated based on the position information. By generating a horn sound in a specific direction in the in-car sound system, the warning signal that the opposite vehicle may send can be simulated. The directional sound effect can be combined with the actual position and direction of the opposite vehicle, so that the driver can more intuitively judge the source of the risk through auditory perception. This multimodal prompting method not only enhances the intuitiveness of the risk prompt, but also effectively improves the driver's perception efficiency.

[0058] By combining the above driving prompts, drivers can quickly perceive the presence of the other vehicle and its potential risks in a complex traffic environment, shorten reaction time, and improve overall driving safety. This method uses multiple perception channels such as vision and hearing to provide drivers with more comprehensive risk information support, while reducing the problems of insufficient information or perception delay that may be caused by traditional single prompt methods.

[0059] Based on the above embodiments, Figure 3 This is the third flow chart of the driving warning method provided by the present invention. Figure 3As shown, first, the vehicle system obtains the driving information of surrounding vehicles (including parameters such as position, speed, acceleration, etc.) through vehicle network technology to ensure the real-time and accuracy of driving information. On this basis, the vehicle system provides two ways of warning: intelligent reminder and manual selection. If the vehicle system determines that an intelligent horn reminder is needed, the algorithm analyzes the list of vehicles that may need to be reminded and sends warning information to them. For example, the vehicle system can analyze whether the following distance is too close. Even if there is no risk of collision, if the distance between the front vehicle and the vehicle is lower than the set threshold (such as less than 50 meters on a highway), it will actively remind the driver to keep a safe distance from the front vehicle. In addition, the vehicle system can also identify vehicles in the blind spot. When the driver turns on the turn signal and prepares to change lanes, if there is a vehicle in the blind spot, the vehicle system will actively send warning information to avoid potential dangers. At the same time, the driver can also manually select the target vehicle that needs to be reminded and send warning information through the three-dimensional imaging interface of the vehicle system. In this process, if the vehicle system detects a potential collision risk, it will actively send a warning message to the vehicle that may collide. When the warning information is received by the target vehicle, its onboard system will trigger internal audio or visual prompts to help the driver perceive potential risks in a timely manner. Audio prompts can remind the source of risks through directional alarm sounds, and visual prompts can mark the location and dynamic information of risky vehicles through a three-dimensional image interface to provide drivers with intuitive risk feedback.

[0060] The traffic warning device provided by the present invention is described below. The traffic warning device described below and the traffic warning method described above can be referenced to each other.

[0061] Figure 4 It is one of the structural schematic diagrams of the traffic warning device provided by the present invention, such as Figure 4 As shown, the device comprises: The driving information acquisition unit 410 is used to acquire the driving information of each surrounding vehicle; A warning vehicle determining unit 420, configured to determine a warning vehicle from the surrounding vehicles based on the driving information of the surrounding vehicles; The warning information sending unit 430 is used to send warning information to the warning vehicle, and the warning information is used to trigger a driving prompt inside the warning vehicle.

[0062] The traffic warning device provided by the present invention avoids the problem of horn noise pollution and weakening the warning effect by reducing the volume by accurately sending warning information to the warning vehicle and triggering driving prompts in the vehicle. The method adopts directional reminders and only targets vehicles that may collide, which improves the accuracy and effectiveness of the warning. At the same time, it overcomes the shortcomings of poor daytime light warning effects and static information on billboards, and can realize real-time risk warnings in complex traffic scenes, significantly improving driving safety and environmental friendliness.

[0063] Based on any of the above embodiments, the warning vehicle determination unit is specifically used for: Based on the driving information of the surrounding vehicles, a vehicle collision warning is provided to the surrounding vehicles; Based on the collision warning results of the surrounding vehicles, a warning vehicle is determined from the surrounding vehicles.

[0067] The traffic warning device provided by the present invention can significantly improve driving safety by analyzing vehicle dynamic information in real time and accurately sending warning information to potential collision vehicles. Compared with the defects of traditional horn noise being widely spread and light warning being poor, this method avoids interference with irrelevant vehicles and the environment, and the warning is more targeted and effective. At the same time, by combining absolute driving information and relative driving information, it can accurately judge the risk of collision, and remind the driver in the form of sound or visual effects through in-vehicle driving prompts, shortening the reaction time and reducing the risk of accidents.

[0068] Based on any of the above embodiments, the early warning information response unit is specifically used to: Based on the warning information, determining the position information of the opposite vehicle relative to the own vehicle; Based on the position information, the opposite vehicle is identified in the surrounding environment image, and / or, based on the position information, the horn sound of the opposite vehicle is directionally simulated.

Figure 6 As shown, the electronic device may include: a processor 610, a communication interface 620, a memory 630 and a communication bus 640, wherein the processor 610, the communication interface 620 and the memory 630 communicate with each other through the communication bus 640.
