[0002] With the vigorous development of the global automobile industry, especially the rise of new energy vehicles, cars have become an indispensable means of transportation in modern society.

Therefore, improving the safety of cars, especially the protection of pedestrians and passengers in the car, has become an important direction for the development of the automobile industry.

[0003] In the field of automotive safety technology, active safety systems are developing particularly rapidly. Among them, active hood technology is an innovative safety measure designed to provide additional protection for pedestrians when a vehicle crashes. However, current active hood technology has certain limitations, especially in terms of false triggering and insufficient linkage with existing sensor systems, which not only increases the financial burden on car owners, but also fails to fully play its due protective role.

[0046] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle protective hood control device, etc. The following takes the vehicle protective hood control device as an example to illustrate this embodiment and the following embodiments.

[0049] The present application embodiment provides a vehicle protective hood control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the present application.

[0050] In this embodiment, the vehicle protective hood control method includes:

[0051] Step S10: Acquire real-time road image.

[0052] It should be noted that the real-time road image here refers to the road image within a certain distance directly in front of the vehicle. Due to the perspective of the image recognition unit, this part of the image will capture the road image of a fan-shaped area directly in front of the vehicle. Moving targets such as vehicles, electric vehicles, and bicycles can be identified within a relatively close distance range. As the perspective expands within a relatively long distance range, pedestrians on both sides of the road can also be identified. By using the trained image recognition model to identify the real-time road image obtained, moving targets with pedestrian characteristics in the image can be identified. Combined with the distance sensor, early warning can be provided.

[0053] It is understandable that the image types of real-time road images, in addition to conventional visible light images, include but are not limited to infrared images, lidar images, multispectral images, etc. For example, infrared images form images by capturing the thermal radiation emitted by objects and can be used at night or in low-light conditions; lidar uses lasers to measure distances and can generate high-precision 3D maps that can accurately sense the distance between moving targets and the current vehicle; and multispectral images can capture spectrums beyond the visible range of the human eye, such as near-infrared, which are used to distinguish between vehicles and pedestrians among moving targets.

[0054] It should be understood that in a complex traffic environment, a single type of sensor may not be able to provide sufficient information. In actual implementation, the robustness and accuracy of the system can be improved by fusing data from multiple sensors (such as integrating visible light cameras, infrared cameras, lidar, etc. into an image recognition module in the above steps).

[0055] Step S20: Obtaining road condition warning information based on the real-time road image.

[0056] It should be noted that after obtaining the real-time road image, the pedestrian feature information in the image can be identified by the pedestrian feature recognition model. Among them, the pedestrian feature recognition model refers to an algorithm or system that uses computer vision technology to detect and identify pedestrian features in an image. This model can extract pedestrian feature information from the road image and classify or identify it. In addition, it is necessary to emphasize the application scenario of this embodiment. Since the active protective hood function is a specialized protection mechanism, its purpose is to automatically pop up to form an elastic buffer when the vehicle collides with a pedestrian during travel, thereby reducing the damage to the pedestrian. In the collision process between the vehicle and the moving object, if the vehicle cannot determine whether the collision is a pedestrian, the active protective hood will pop up from a safety perspective. However, for the vehicle driver, if the active protective hood is still popped up when the vehicle collides with the vehicle, it is tantamount to increasing the maintenance cost. The false triggering will also reduce the user's driving experience. Therefore, the key to solving the false triggering lies in the accurate identification of the collision object and the timely closing of the active hood function when there is no collision risk.

[0057] It is understandable that since the protection objects of the active hood are specifically pedestrians, further, the pedestrians here refer to all kinds of pedestrians such as cyclists, electric bike riders, and pedestrians on foot. In layman's terms, all pedestrians who may have physical contact with the vehicle during a collision are included. Therefore, the key to identifying the collision object is to identify moving objects with pedestrian characteristics in the real-time road image, analyze their position, speed and direction of movement, assess the collision risk and urgency, and issue a collision warning based on the analysis results.

[0058] It should be understood that in addition to pedestrians, the system should also be able to identify other types of moving objects, such as vehicles, bicycles, etc., in order to more comprehensively assess the risk of collision. After identifying pedestrians and other moving objects, the system needs to analyze their relative position and distance to the vehicle to determine whether there is a possibility of collision. Furthermore, the possibility of collision can be determined based on the current vehicle speed. For example, if there is a moving object with pedestrian characteristics at a position close to the vehicle, then it should always be considered that there is a risk of collision. When there is a moving object with pedestrian characteristics at a position far from the vehicle, if the current vehicle speed is slow, it can be considered that the risk of collision is small. On the contrary, if the vehicle speed is fast, it can be considered that there is a certain risk of collision. In summary, based on the positional relationship between the moving object with pedestrian characteristics and the vehicle, a series of conditions such as vehicle speed can be comprehensively used to obtain the collision probability of the current road section, which can be used as road condition warning information.

[0059] Step S30: adjusting the start / stop state of the active protective hood according to the road condition warning information.

[0060] It should be noted that the road condition warning information corresponds one-to-one to the start and stop status of the active protection hood, and the vehicle's start and stop status includes three types: open state, pre-start state and closed state.

[0061] In one embodiment, adjusting the start / stop state of the active protective hood according to the road condition warning information includes: when the road condition warning information is a first type of warning, adjusting the start / stop state of the active protective hood to an open state; when the road condition warning information is a second type of warning, adjusting the start / stop state of the active protective hood to a pre-start state; when the road condition warning information is a third type of warning, adjusting the start / stop state of the active protective hood to a closed state.

[0062] It is understood that the open state is the fully activated state of the active protective hood. When the system receives the first type of warning information, it means that there is a high risk or an imminent collision. At this time, the system will adjust the active protective hood to the open state to provide immediate protection. The pre-start state is an intermediate state between the open and closed states. When the system receives the second type of warning information, it indicates that there is a certain risk of collision, but it may not be imminent. At this time, the system will adjust the active protective hood to the pre-start state. In this state, the hood may have been partially deployed or in a standby state so that it can be quickly fully deployed when it is confirmed that the collision is inevitable; the closed state is the inactive state of the active protective hood. When the system receives the third type of warning information, it means that the current road conditions are safe, no collision risk is detected, or the risk is low. At this time, the system will adjust the active protective hood to the closed state to avoid unnecessary activation and reduce mechanical wear and energy consumption.

[0063] It should be understood that this state division allows the system to flexibly adjust the working state of the active protection hood according to the real-time road conditions and collision risk assessment to achieve the best safety protection effect. At the same time, this also helps to balance the frequency of use of the hood and maintenance costs, ensuring that the system can provide effective protection when it is really needed.

[0064] The present application obtains real-time road images; obtains road condition warning information based on the real-time road images; and adjusts the start and stop states of the active protective hood based on the road condition warning information.

[0065] In summary, the vehicle protective hood control method proposed in the present application can activate the hood in time when it is really necessary to protect pedestrians by intelligently identifying pedestrian characteristics and warning information, thereby reducing the situation where the hood is accidentally triggered in collisions without direct contact with people, significantly improving the control accuracy of the vehicle's active hood, reducing maintenance costs, and at the same time enhancing the ability to protect pedestrians and optimizing the driving experience.

[0066] Reference Figure 2 , Figure 2This is a flow chart of a second embodiment of a vehicle protective hood control method of the present application. Based on the above first embodiment, the second embodiment of the vehicle protective hood control method of the present application is proposed.

[0067] In this embodiment, the step S20 includes:

[0068] Step S201: Divide the real-time road image into a first warning area and a second warning area.

[0069] like Figure 3 As shown, Figure 3 This is a schematic diagram of area division according to the second embodiment of the vehicle protective hood control method of the present application.

[0070] It should be noted that the figure divides the area in the direction of vehicle travel into two areas with different shadow types along the distance from the vehicle. The area closer to the vehicle in the two areas is used as the first warning area, and the part farther away is used as the second warning area.

[0071] In one embodiment, dividing the real-time road image into a first warning area and a second warning area includes: determining a collision reaction depth based on the real-time vehicle speed and the collision reaction time; dividing a portion of the real-time road image whose longitudinal distance is the collision reaction depth into the first warning area, and dividing a portion whose longitudinal distance exceeds the collision reaction depth into the second warning area.

[0072] It should be noted that since it takes a certain amount of time for the vehicle to recognize pedestrians and then give feedback to the vehicle system to control the active hood opening, this time is called the system response time. This time is limited by the speed at which the image data and processing results are transmitted between the modules within the system and the coordination between the components of the system. For safety reasons, the vehicle must respond promptly within this time. Therefore, assuming that after testing, the time from the vehicle identifying the pedestrian and judging that the pedestrian is about to collide with the vehicle, and returning the judgment result to the system, the system opens the active protective hood according to the judgment result. This time is defined as the collision response time. Combined with the distance calculated by the current vehicle speed, this distance is the collision response depth, that is, if there is a moving object with pedestrian characteristics in the area from the front of the vehicle to this distance, it should be ensured that the active protective hood is open. This area is the first warning area. On the other hand, when the area exceeds this collision response depth, it is used as the second warning area.

[0073] It is understandable that since the range of recognition of the vehicle intelligent recognition unit is fixed, the slower the vehicle speed, the longer the depth of the collision reaction, that is, the size of the first warning area and the second warning area is adjusted with the vehicle speed. The advantage of this is that the system can reasonably allocate computing resources and attention according to the division of the warning area, give priority to processing the data in the first warning area, and ensure that key information is responded to quickly. On the other hand, if there are pedestrian features in the divided second warning area, they can be used as candidate data for the first warning area. When the vehicle speed or the pedestrian features in the second warning area meet certain conditions, the state of the active protection hood can be adjusted to the pre-start or open state.

[0074] Step S202: based on the pedestrian feature recognition model, respectively obtain pedestrian feature information of the first warning area and the second warning area.

[0075] It should be noted that the pedestrian feature recognition model is a computer vision technology that can detect pedestrians in images or video sequences and extract features that help identify individuals. These models are usually based on machine learning or deep learning algorithms and can process pictures or video frames of pedestrians to identify and distinguish different pedestrians. The pedestrian feature information obtained by the pedestrian feature recognition model refers to the distance between the moving object containing pedestrian features and the current vehicle and the direction of the moving object, also in terms of Figure 3 Taking the scene diagram as an example, the first warning area can basically only cover the pedestrian and vehicle data directly in front of the current road and identify them, while the second warning area can cover the pedestrian data on the roads on both sides. Since the collision risk of pedestrians crossing the road is much higher than the collision risk caused by moving objects moving side by side longitudinally, if the direction of the moving object in the second area is horizontal or opposite, the current risk is judged to be high. On the contrary, if the direction is consistent with the vehicle's direction of travel, it is judged to be low risk.

[0076] Step S203: Obtaining road condition warning information according to the pedestrian characteristic information in the first warning area and the pedestrian characteristic information in the second warning area.

[0077] It should be noted that with the help of image processing and recognition technology, it is possible to analyze and interpret pedestrians' movement patterns, speeds, directions and other characteristic information in real time. The system integrates this information and combines it with the vehicle's current driving status, such as speed and driving path, to assess the potential risk of collision. This assessment is dynamic and can be quickly adjusted according to changes in traffic conditions to ensure the accuracy and timeliness of warning information.

[0078] Understandably, the first warning zone is concerned with the likelihood of an imminent collision. If pedestrian features are detected in this zone, the system immediately raises the warning level, as the probability of a collision is high in this case. In addition, the system also considers the specific behavior of the pedestrian, such as whether he is running or suddenly changing direction, which may affect the level and urgency of the warning.

[0079] It should be understood that the second warning area, although farther from the vehicle, is equally important for assessing the overall traffic conditions and predicting potential risks. The system monitors the distribution and movement trends of pedestrians in this area, as well as the impact they may have on the vehicle's route. For example, if pedestrians in the second warning area show signs of crossing the road, even if they are still far away from the vehicle, the system may adjust the warning level in advance based on the vehicle speed and the pedestrian's expected movement trajectory to ensure that there is enough time to take evasive measures. In addition, after receiving road condition warning information, the system will display corresponding warning information such as "There are pedestrians / bicycles / electric vehicles ahead, please drive carefully" based on the identified vulnerable road users such as pedestrians, bicycles or electric vehicles, reminding the driver to pay attention and take corresponding driving behaviors, so that the driver can respond quickly to potential dangers, thereby reducing the occurrence of traffic accidents.

[0080] The present embodiment provides a vehicle protective hood control method. The present embodiment first divides the real-time road image into a first warning area and a second warning area; based on a pedestrian feature recognition model, the pedestrian feature information of the first warning area and the second warning area are respectively obtained; and according to the pedestrian feature information of the first warning area and the pedestrian feature information of the second warning area, road condition warning information is obtained.

[0081] In summary, intelligent area division and pedestrian feature recognition have achieved rapid and accurate collision risk assessment, effectively improving driving safety. Dynamically adjusted warning areas and real-time updated road conditions ensure the timeliness and accuracy of system response, reduce false triggers, optimize resource allocation, and enhance driving experience through intuitive driver prompts, and adapt to changing traffic environments.

[0082] Reference Figure 4 , Figure 4 This is a flow chart of a third embodiment of a vehicle protective hood control method of the present application. Based on the above second embodiment, the third embodiment of a vehicle protective hood control method of the present application is proposed.

[0083] In this embodiment, the step S203 includes:

[0084] Step S20301: If there are pedestrian features in the first warning area, the road condition warning information is set as the first type of warning.

[0085] Furthermore, if there are no pedestrian features in the first warning area, when the real-time vehicle speed is greater than the warning speed threshold and there are pedestrian features in the second warning area, the road condition warning information is set as a first type of warning.

[0086] It should be noted that the basis for the warning classification in this application needs to be explained first. Some principles need to be determined based on the most basic division of vehicles into low-speed and high-speed, closer areas and farther areas. First of all, when there are pedestrian features in the first warning area close to the vehicle, no matter whether the current vehicle speed is fast or slow, it should be regarded as a high risk of collision, and it should be regarded as a possible collision. Therefore, this type of relatively urgent situation is regarded as the first type of warning. Under the first type of warning, the active protective hood is in the open state so that it can be started at any time.

[0087] It can be understood that if there are no pedestrian features in the first warning area and the current vehicle speed is greater than the set warning speed threshold, it should be considered that there is still a certain risk. When there are pedestrian features in the second warning area, it should be classified as consistent with the above situation and the road condition warning information should be set to the first type of warning.

[0088] Step S20302: If the real-time vehicle speed is greater than the warning speed threshold and there is no pedestrian feature in the second warning area, the road condition warning information is set to the second type of warning.

[0089] Furthermore, if the real-time vehicle speed is less than the warning speed threshold and there are pedestrian features in the second warning area, the road condition warning information is set to the second type of warning.

[0090] It can be understood that, similar to the previous steps, under the premise that there are no pedestrian features in the first warning area, when only one of the two conditions is met, that is, the vehicle speed is fast or there are pedestrian features in the second warning area, the active protective hood function can be adjusted to the pre-start state, which corresponds to setting the road condition warning information to the second type of warning.

[0091] Step S20303: If the real-time vehicle speed is less than the warning speed threshold and there is no pedestrian feature in the second warning area, the road condition warning information is set to the third type of warning.

[0092] It should be noted that only when there are no pedestrian features in the two warning areas and the current vehicle speed does not exceed the warning speed threshold, the system believes that there is no imminent collision threat, and therefore will not immediately trigger active protection measures. The active hood function can be completely turned off, and the road condition warning information will be set to the third type of warning accordingly.

[0093] It is understandable that by reducing unnecessary active protection hood activation, maintenance costs can be reduced and energy efficiency can be improved. Combined with the corresponding warning information category, the corresponding warning information can also be displayed through the instrument cluster to give the driver an early warning of the current collision risk.

[0094] The present embodiment provides a vehicle protective hood control method. The present embodiment first divides the front of the vehicle into two warning areas according to the distance, identifies the pedestrian features in the images of the two areas through an image recognition model, and divides the start / stop state of the hood into open, pre-start and closed according to the pedestrian features in the two areas and the vehicle speed. In this way, the vehicle can manage collision risks more intelligently and adaptively, while ensuring that the driver obtains the necessary information to make appropriate driving decisions.

[0095] In summary, by intelligently identifying pedestrian characteristics and warning information, the hood can be activated in a timely manner when it is really necessary to protect pedestrians, thereby reducing the situation of false triggering of the hood in collisions without direct contact with people, significantly improving the control accuracy of the vehicle's active hood, reducing maintenance costs, while enhancing the ability to protect pedestrians and optimizing the driving experience.
