[0040] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] It should be clear that the described embodiments are only some embodiments of the present invention, not all 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.

[0042] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0043] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0044] With the rapid development of intelligent transportation systems, vehicle safety technology has become an important research direction in the automotive industry and traffic management. Among the many vehicle safety technologies, the automatic emergency braking system has attracted much attention because it can effectively reduce traffic accidents and casualties. However, existing AEB systems mainly rely on on-board sensors, such as radar, lidar, and cameras, to detect obstacles ahead and trigger emergency braking. Although these systems have improved driving safety to a certain extent, they still have limitations, especially in scenarios where multiple vehicles are driving continuously, the rear vehicle lacks timely perception and response to the emergency braking behavior of the front vehicle, increasing the risk of rear-end collisions.

[0045] In the context of intelligent connected vehicles (ICV), vehicles can share real-time information, including location, speed, and driving status, through vehicle-to-vehicle (V2V) communication technology. This information sharing provides new possibilities for improving driving safety, especially in emergency braking scenarios. However, most existing V2V communication technologies focus on the anonymity of vehicles and ignore the use of vehicle identification information (such as license plate information) to improve the accuracy and timeliness of emergency braking response.

[0046] In addition, as an indispensable part of modern intelligent transportation systems, map applications have been able to provide real-time traffic information, navigation services, vehicle positioning and other functions. However, the application of map applications in emergency braking scenarios is still limited, especially in terms of using vehicle identification information to improve emergency braking response. Therefore, the present invention provides an emergency braking method to solve the above problems.

[0047] Please refer to Figure 1 , which is a flow chart of an emergency braking method provided by an embodiment of the present invention, comprises the following steps:

[0048] Step S01, obtaining the license plate information of the vehicle ahead.

[0049] In this embodiment, this step is a key link in realizing inter-vehicle communication and intelligent traffic management, which allows the current vehicle to read and parse the text and numbers on the license plate, collect the necessary identity information, and then establish an identification-based communication link between vehicles. In this way, the vehicle can accurately identify and track a specific vehicle, providing accurate data support for subsequent emergency braking response.

[0050] In some embodiments, after obtaining the license plate information of the vehicle ahead, the method may further include:

[0051] Based on the license plate information of the vehicle in front, the front and rear position relationship of the vehicle in front and the current vehicle can be accurately located in the map application.

[0052] The existing technology is limited by the positioning accuracy of the vehicle positioning system. When the distance between vehicles is very close, it is impossible to distinguish the front and rear position relationship, resulting in the warning information generated by the vehicle after emergency braking cannot be accurately and timely sent to the rear vehicle, increasing the risk of traffic accidents.

[0053] In order to solve this problem, after successfully obtaining the license plate information of the vehicle in front, this embodiment uses the license plate information to determine the relative position between the vehicle in front and the current vehicle in the map application. Specifically, by inputting the license plate information of the vehicle in front into the map application, the system can identify and track the precise position of the vehicle in front, thereby clearly marking the front and rear position relationship of the two vehicles on the road on the map. At the same time, the system can also build a comprehensive traffic network through the map application combined with the license plate information uploaded by other vehicles, and accurately grasp the front and rear position relationship of all vehicles in the current range. This method not only improves the accuracy of position judgment, but also provides technical support for instant communication in emergency situations, effectively reduces traffic accidents caused by incorrect position judgment, and improves road driving safety.

[0054] In some embodiments, the license plate information of the vehicle ahead can be obtained by a high-definition camera installed on the front bumper of the vehicle. When the vehicle is driving on a main road in the city, the camera automatically focuses and captures the license plate image of the vehicle ahead, and obtains the license plate information of the vehicle ahead based on the license plate image.

[0055] Step S02: Add the vehicle ahead as a monitoring object in the map application according to the license plate information.

[0056] In this embodiment, the system specially marks the vehicle ahead in the map application according to the license plate information, sets the vehicle ahead as a monitoring object in the map application, and starts to continuously track and monitor the position and driving status of the vehicle ahead. In this way, the current vehicle can receive the driving data of the vehicle ahead in real time, so that when the first emergency braking information uploaded by the vehicle ahead is monitored, the emergency braking function can be activated in time to reduce the probability of traffic accidents.

[0057] In some embodiments, assume that a car equipped with an intelligent driving assistance system is driving on a city road. The system captures the license plate number "Province A12345" of the vehicle in front through the on-board camera, and successfully parses the license plate information using the built-in optical character recognition technology. Subsequently, the system automatically inputs this license plate number into the integrated map application and sets the "Province A12345" vehicle in front as the monitoring object. The map application will continue to track the location of the "Province A12345" vehicle and update its driving status in real time, providing the current vehicle with real-time information about the vehicle in front.

[0058] Through this setting, the driver of the current vehicle or the autonomous driving system can be informed in advance of any emergency operations of the vehicle ahead, such as emergency braking, and take corresponding safety measures. This monitoring mechanism based on license plate information significantly improves the current vehicle's ability to perceive the surrounding environment.

[0059] Step S03, when the first emergency braking information uploaded by the vehicle ahead is monitored in the map application, the emergency braking function is activated.

[0060] In this embodiment, when the map application of the smart vehicle successfully sets the front vehicle "Province A12345" as the monitoring object, the system begins to monitor the dynamics of the vehicle in real time. Once the emergency braking function of the front vehicle is activated, its vehicle system will automatically upload this key information - the "first emergency braking information" - to the map application. Almost at the same time, the map application of the current vehicle will immediately trigger the emergency braking function of the vehicle after monitoring the first emergency braking information, without waiting for the driver's response, so as to quickly reduce the speed or stop the vehicle to avoid or mitigate possible collisions.

[0061] This emergency braking response mechanism based on real-time vehicle networking communication greatly improves driving safety. Through the vehicle's own sensors and braking system, combined with direct communication between vehicles, it achieves instant response to the behavior of the vehicle in front, effectively reducing traffic accidents caused by delayed driver reaction time, especially on highways or congested urban roads. This function is particularly important. This embodiment achieves a rapid response to the sudden behavior of the vehicle in front, greatly improving driving safety and reducing the risk of rear-end collisions caused by untimely driver response.

[0062] Based on the above embodiments, in some embodiments, after executing step S03 to start the emergency braking function, the method may further include the following steps:

[0063] Step S11, determining the rear vehicle of the current vehicle based on the front and rear position relationship of the current vehicle in the map application.

[0064] In this embodiment, the system uses the map application and the license plate information uploaded by other vehicles to construct a traffic network that includes the front and rear position relationship of all vehicles in the current range, obtains the front and rear position relationship of the current vehicle based on the traffic network, and determines the vehicle behind the current vehicle. This process enables the system to accurately identify which vehicles are following the current vehicle, providing key information for subsequent safety warnings and traffic management.

[0065] Step S12, generating reminder information, and sending the reminder information to all rear vehicles within a preset range through a map application.

[0066] In this embodiment, after the emergency braking function is activated, the system automatically creates an emergency reminder message. This message is intended to warn the rear vehicle to pay attention to the emergency braking situation ahead, so as to remind the rear vehicle driver to take corresponding safety measures. Subsequently, using the communication function of the map application, the system broadcasts this reminder message in real time to all rear vehicles within a preset range, ensuring that they can receive this key information in a timely manner, thereby improving the safety warning capability of the entire traffic flow and reducing traffic accidents caused by emergency braking.

[0067] After the emergency braking function is activated, the present embodiment determines the vehicle behind the current vehicle based on the front-rear position relationship of the current vehicle in the map application, generates a first reminder message, and sends the reminder message to all vehicles behind the current vehicle within a preset range through the map application. The function of the reminder message is to timely notify the vehicles behind the current vehicle and remind the driver to slow down or stop the vehicle, thereby effectively preventing the occurrence of a multi-vehicle chain rear-end collision. In this way, the present method significantly improves the safety of road driving and reduces secondary disasters in emergency situations.

[0068] Based on the above embodiments, in some embodiments, the method may further include the following steps:

[0069] When reminder information of other vehicles is received in the map application, the reminder information of other vehicles is output to the information reminder device.

[0070] This embodiment allows the current vehicle to transmit emergency reminders or important notifications sent by other vehicles through the map application to the information reminder system of the vehicle in real time. Specifically, when the vehicle's map application detects reminder information such as emergency braking of the vehicle ahead, traffic accidents or other road hazards, the system will automatically output these reminder information through the vehicle's display screen, audio system or other user interface to remind the driver to pay attention and take corresponding safety measures. This process ensures that the driver can get timely updates on the surrounding traffic conditions, thereby improving driving safety and road efficiency.

[0071] Please refer to Figure 2 , is a schematic diagram of an embodiment of the present invention providing a method for vehicles to communicate emergency braking information through a map application. Figure 2 As shown in the figure, the relative positions of five vehicles on the road and the information transmission process between them are shown, including the following processes:

[0072] 1) When the vehicle ahead encounters an emergency and applies emergency braking, it will do the following:

[0073] Upload first emergency braking information: The vehicle uploads its emergency braking status information to the map application.

[0074] Generate reminder message: At the same time, the vehicle generates a reminder message to notify the vehicle behind.

[0075] 2) The current vehicle monitors the emergency braking information of the vehicle ahead through the map application and performs the following operations after receiving the information:

[0076] Activate the emergency braking function: The current vehicle automatically activates its emergency braking function based on the received emergency braking information to avoid collision with the vehicle in front.

[0077] 3) The vehicle behind and the current vehicle receive the reminder information through the map application and perform the following operations:

[0078] Output the reminder information to the information reminder device: the rear vehicle and the current vehicle will output the received reminder information through their on-board information reminder system (such as audio, display, etc.) to warn the driver to take corresponding safety measures.

[0079] The entire process embodies the intelligent traffic information sharing between vehicles through map applications, aiming to improve driving safety and reduce traffic accidents caused by emergency braking.

[0080] Based on the above technical solution, the emergency braking method provided by the embodiment of the present invention obtains the license plate information of the vehicle in front; adds the vehicle in front as a monitoring object in the map application according to the license plate information; and activates the emergency braking function when the first emergency braking information uploaded by the vehicle in front is monitored in the map application. The present invention achieves accurate monitoring of the emergency braking behavior of the vehicle in front by acquiring the license plate information of the vehicle in front in real time and using it as a monitoring object in the map application. When the system receives the first emergency braking information uploaded by the vehicle in front through the map application, the emergency braking function of the vehicle can be quickly triggered, thereby significantly improving the response speed to emergencies, effectively reducing the occurrence of rear-end collisions, and enhancing road driving safety. This method utilizes vehicle identification information and vehicle networking technology to achieve rapid response to emergencies and provide drivers with more reliable safety protection.

[0081] Please refer to Figure 3 , which is a flow chart of another emergency braking method provided by an embodiment of the present invention. Based on the above embodiment, in some embodiments, before executing step S01 to obtain the license plate information of the vehicle ahead, the following may also be performed: Figure 3 Steps shown:

[0082] Step S21, download and install the map application.

[0083] Step S22, registering an account in the map application according to the input license plate information.

[0084] In this embodiment, after downloading and installing the in-vehicle map application, the user needs to create an account associated with his or her vehicle and enter the license plate number of his or her vehicle during the registration process. This step ensures a one-to-one correspondence between the account and the vehicle, that is, each account is bound to a unique license plate information. This binding mechanism not only meets the basic requirements of the in-vehicle map for accurate positioning of the vehicle, but also enhances the accuracy of vehicle-to-vehicle interaction through the recognition of the license plate number. It allows the system to accurately identify and track each vehicle in a complex traffic environment, laying a solid foundation for the realization of a smart traffic interactive reminder system, so that the following vehicle can promptly identify the license plate of the preceding vehicle, and accurately locate the relative position of the vehicle and other vehicles based on this information, thereby providing effective early warning in emergency situations.

[0085] Step S23, log in to the map application through the account, and navigate through the map application.

[0086] In this embodiment, after logging into the map application using a personal account, the user can use various navigation functions provided by the map application, such as route planning, real-time traffic information, and destination search, to guide driving. This process not only provides users with convenient navigation services, but also enables the map application to provide more personalized and accurate traffic information due to the binding of the account and vehicle information, thereby enhancing driving safety and navigation accuracy.

[0087] Based on the above technical solution, this embodiment provides a comprehensive intelligent navigation and vehicle tracking platform for the driver by downloading and installing a map application, registering an account according to the input license plate information, and logging into the map application through the account to navigate before obtaining the license plate information of the vehicle ahead. This embodiment not only enhances the personalized service capabilities of the map application, but also provides a safe and convenient navigation environment for the vehicle. In this way, the driver can plan the route more effectively, and at the same time, the system can track and identify the vehicle more accurately, providing a solid foundation for subsequent emergency braking reminders and traffic management, thereby improving overall driving safety and efficiency.

[0088] Please refer to Figure 4 ,for Figure 1 A flowchart of an actual performance of S01 in a method of emergency braking is provided. In some embodiments, the license plate number of the vehicle in front can be captured and recognized by using a vehicle-mounted camera or other sensor technology. This process involves technical steps such as image acquisition, preprocessing, license plate positioning, character segmentation and recognition to ensure accurate acquisition of text and digital information on the license plate, and to provide accurate identity recognition for the vehicle.

[0089] For example, as mentioned in step S01, the license plate information of the vehicle ahead is obtained, and the establishment process may specifically include the following steps: Figure 4Steps shown:

[0090] Step S31, obtaining a picture of the vehicle in front through an image acquisition device.

[0091] In this embodiment, by using an image acquisition device such as a vehicle-mounted camera, the vehicle in front is photographed in real time to obtain image data of its license plate and other related information. This process is the basis of license plate recognition technology, which ensures the smooth progress of subsequent image processing and analysis, and provides original visual information for realizing functions such as vehicle monitoring, traffic management and intelligent driving assistance. In this way, the details of the vehicle in front can be effectively captured, laying a solid foundation for subsequent image analysis and data processing.

[0092] In some embodiments, a vehicle-mounted camera is used as an image acquisition device, and the camera can be installed above the front windshield of the vehicle, facing the direction of the vehicle's travel. When the vehicle is driving on the road, the camera is automatically activated to capture the image of the vehicle in front in real time. For example, in an actual driving, the camera successfully captured the rear image of a car 100 meters ahead, including its license plate number. This image is then transmitted to the vehicle's central processing system, providing raw data for subsequent image processing and license plate recognition.

[0093] This setup ensures that clear images of vehicles ahead can be stably obtained under various lighting and weather conditions. These images contain not only license plate information, but also other features such as vehicle model and color, providing rich data support for vehicle identification and subsequent intelligent transportation applications.

[0094] Step S32, preprocessing the image to obtain a preprocessing result.

[0095] In this embodiment, the preprocessing may include at least one of grayscale processing, binarization processing, and noise reduction processing. The system performs a series of preprocessing operations on the front vehicle picture obtained by the vehicle-mounted camera to improve the accuracy of subsequent license plate recognition. Specifically, the preprocessing step may include converting the color image into a grayscale image to reduce the amount of data and highlight the key information in the image; then, applying binarization processing to convert the grayscale image into an image containing only black and white pixels, so that the outline and characters of the license plate are clearer; finally, performing noise reduction processing to eliminate noise in the image and improve the recognition rate of the license plate area. Through the preprocessing operation, it is ensured that the image has the best image quality before the license plate positioning and character recognition.

[0096] Step S33, performing license plate positioning processing, character cutting processing and character recognition processing on the pre-processing result in sequence to obtain license plate information.

[0097] In this embodiment, after the preprocessing step, the preprocessed image is subjected to license plate location processing, and the license plate area is identified and located in the preprocessed image by using a specific algorithm. Next, the located license plate area is subjected to character cutting processing, each character on the license plate is separated from the background, and a separate image is created for each character. Finally, through character recognition processing, each cut character image is analyzed using optical character recognition technology to identify the letters and numbers on the license plate. This series of processing steps enables the system to accurately extract license plate information from the preprocessing results, including the license plate number and possible other registration information.

[0098] Based on the above technical solution, this embodiment uses a series of image processing technologies to accurately obtain the license plate information of the vehicle in front, thereby improving the accuracy and efficiency of license plate recognition and providing reliable data support for inter-vehicle communication.
