[0037] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] The following describes the vehicle trunk warning method, device, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problems mentioned in the above background technology, the present application provides a vehicle trunk warning method, in which the actual distance between the vehicle trunk and the surrounding obstacles is detected; when the actual distance is less than the preset safety distance, the maximum openable door angle of the vehicle trunk is calculated according to the actual distance; and a warning prompt is generated according to the maximum openable door angle, and at least one acoustic reminder device and / or at least one optical display device of the vehicle is controlled to perform a collision warning reminder inside and / or outside the vehicle according to the warning reminder. The present application determines the maximum openable door angle according to the distance between the trunk door and the surrounding obstacles to perform a collision warning, avoid collision when opening the trunk, thereby ensuring the safety of the vehicle and passengers, and greatly improving the user experience. Therefore, the problem that the related technology cannot predict whether the vehicle trunk will collide with the surrounding obstacles when it is opened, and it is difficult to avoid the occurrence of trunk door collision events is solved.

[0039] Specifically, Figure 1 A flowchart of a vehicle trunk warning method provided in an embodiment of the present application.

[0040] like Figure 1 As shown, the vehicle trunk warning method includes the following steps:

[0041] In step S101 , the actual distance between the vehicle trunk and surrounding obstacles is detected.

[0042] It is understandable that in real life scenarios, such as in a parking lot, when the distance between two adjacent vehicles is small and there is an obstacle behind the vehicle, when the passenger is not paying attention or miscalculates, it is easy for the vehicle trunk door to collide with nearby walls, adjacent vehicles or obstacles, thereby causing economic losses to the user. Therefore, before opening the trunk, the embodiment of the present application can detect whether there are obstacles around the vehicle trunk. If there are obstacles, it is necessary to obtain the actual distance between the vehicle trunk and the surrounding obstacles, so as to determine whether the trunk can be opened safely according to the actual situation, thereby avoiding the occurrence of situations such as the trunk door being damaged due to hitting obstacles during the trunk opening process, and improving the user experience.

[0043] Optionally, in one embodiment of the present application, before detecting the actual distance between the trunk of the vehicle and surrounding obstacles, it also includes: detecting whether the vehicle meets preset warning conditions; when it is detected that the vehicle meets the preset warning conditions, controlling the vehicle to enter the trunk door opening warning mode.

[0044] Before detecting the actual distance between the vehicle trunk and surrounding obstacles, the embodiments of the present application can also detect whether the vehicle meets the warning conditions, and then control the vehicle to enter the trunk door opening warning mode to perform the detection of the actual distance between the vehicle trunk and surrounding obstacles.

[0045] Specifically, in the embodiment of the present application, the above-mentioned warning conditions may include whether the gear is in P gear or N gear, whether the handbrake is pulled up, and whether the vehicle speed is zero, etc. When the vehicle meets the above-mentioned warning conditions, the user can click on the icon or button on the vehicle display screen or the steering wheel, or issue a voice command to turn on the trunk door opening warning function to enter the trunk door opening warning mode, and then the user can choose to turn on one or more distance measuring devices, such as infrared detectors, laser distance sensors and ultrasonic radars, millimeter wave radars or binocular cameras, etc., through components such as the display screen, or use the system default detection device to identify whether there are obstacles around the trunk. If there are obstacles, the distance between the trunk and the obstacle can be detected by the above-mentioned infrared detectors, ultrasonic radars or binocular cameras, etc., or the above-mentioned multiple detection devices can be used for distance measurement at the same time to obtain multiple distance data, and the minimum distance value is taken as the actual distance between the vehicle trunk and the obstacle, and the obtained distance data is displayed on the vehicle display screen or instrument panel, and a voice reminder can also be made.

[0046] For example, after the user parks the vehicle in the parking lot, he clicks on the trunk door opening warning icon on the vehicle display screen to turn on the trunk door opening warning function, enter the trunk door opening warning mode, and display the icon of this mode on the vehicle dashboard. Then the user can choose to turn on infrared detectors and ultrasonic radars and other devices through the vehicle display screen to detect whether there are obstacles and the distance between the vehicle and the obstacle. When an obstacle is detected, the obstacle distance detected by the infrared detector and ultrasonic radar is obtained respectively. If the distances obtained are 30cm and 25cm respectively, 25cm is taken as the actual distance between the vehicle trunk and the obstacle. In addition, the embodiments of the present application can also obtain the type of obstacle through binocular cameras and fill lights and other devices combined with deep learning, and accurately measure the distance to the obstacle through the camera ranging algorithm.

[0047] It should be noted that the above-mentioned infrared detectors, ultrasonic radars or binocular cameras and other equipment can be installed on the trunk door or on both sides of the trunk. Users can also make adjustments according to actual conditions and usage effects. There are no specific restrictions here.

[0048] Therefore, it is judged whether the vehicle meets the warning conditions before the distance measurement, which ensures the safety of the vehicle and passengers and improves the safety and intelligence level of the vehicle. In addition, the embodiment of the present application identifies and detects the distance between the vehicle and the obstacle through multiple devices according to the user's personal wishes, improves the detection accuracy of the distance and the user's participation, and improves the user's experience.

[0049] In step S102, when the actual distance is less than the preset safety distance, the maximum openable angle of the vehicle trunk is calculated according to the actual distance.

[0050] When the actual distance between the vehicle trunk and surrounding obstacles is detected and the actual distance is less than the distance threshold, it means that a collision may occur when the vehicle trunk is opened. Therefore, the embodiment of the present application can be combined with the maximum opening angle of the vehicle trunk to control the safe opening of the trunk. In this way, it is possible to predict whether the vehicle trunk door will collide with surrounding obstacles when opening the door, and to avoid the situation where passengers open the door and hit obstacles in unknown circumstances through early warning, thereby ensuring the safety of the vehicle and greatly improving the user experience.

[0051] Optionally, in one embodiment of the present application, the preset safety distance is obtained by the straight-line distance that the trunk door of the vehicle extends outward when the trunk door of the vehicle is opened to the maximum opening angle.

[0052] It should be noted that the above distance threshold adopts the straight-line distance of the vehicle trunk door extending outward when the vehicle trunk door is opened to the maximum opening angle. When the distance information is greater than or equal to the straight-line distance, it indicates that the vehicle trunk door will not collide when it is opened, and the body controller does not perform any operation. When the distance information is less than the straight-line distance, it indicates that the vehicle trunk door will inevitably collide when it is opened. Therefore, the above distance data is converted into a bus signal and sent to the body controller, door controller and other components through the CAN (Controller Area Network) bus to control the opening of the trunk. At the same time, the body controller can also transfer the alarm signal to the instrument through the gateway for early warning, such as Figure 2 As shown, whether the trunk can be opened is quantified based on the above-mentioned straight-line distance, and the straight-line distance of the vehicle trunk door extending outward when the vehicle trunk door is opened to the maximum opening angle is used as the threshold, thereby ensuring the reliability of the data, thereby improving the accuracy of judging whether a collision will occur during the trunk opening process, and further improving the safety performance of the vehicle.

[0053] Optionally, in one embodiment of the present application, it also includes: detecting an actual door opening angle of a vehicle trunk; when it is detected that the actual door opening angle reaches a maximum door opening angle, controlling the vehicle trunk to issue a collision warning reminder while controlling the vehicle trunk to stop opening.

[0054] When the body controller determines that the vehicle trunk may collide with surrounding obstacles when opened, further, the embodiment of the present application can also reasonably control the actual opening angle of the trunk so that the trunk can be opened without colliding with obstacles.

[0055] Specifically, when the body controller determines that the trunk of the vehicle may collide with surrounding obstacles when it is opened, the vehicle system calculates the maximum door opening angle when the trunk of the vehicle cannot collide with surrounding obstacles, that is, the anti-collision door opening angle, and sends the angle data to the corresponding door controller, etc. When the door opening angle of the trunk door of the vehicle is less than the maximum door opening angle, the trunk door of the vehicle will not collide with surrounding obstacles; when the door opening angle of the trunk door of the vehicle is greater than or equal to the maximum door opening angle, the trunk door of the vehicle will collide with surrounding obstacles.

[0056] It should be noted that, in the embodiment of the present application, during the trunk opening process, the actual opening angle of the trunk can be detected in real time through devices such as a vehicle-mounted angle sensor, and the angle information can be converted into a bus signal and displayed in real time through devices such as a vehicle-mounted display screen or a vehicle dashboard. When the actual opening of the trunk reaches the maximum opening angle, the angle information on the control display screen or dashboard can be continuously flashing, and the user can be further warned through devices such as voice prompts or buzzers. At the same time, the vehicle trunk is controlled to stop opening.

[0057] For example, when the body controller determines that opening the vehicle's trunk door will cause a collision with surrounding obstacles, but the user still needs to open the trunk according to actual needs, the user can press the trunk opening button in the car. At the same time, the embodiment of the present application can display the maximum door opening angle calculated by the vehicle-mounted system on the vehicle dashboard or vehicle-mounted display screen, and can send a request to the user to confirm opening the trunk. When the user receives the request, the trunk opening action can be executed. At the same time, the real-time opening angle of the trunk can be obtained through the on-board angle sensor and other devices, and the data is transmitted back to the on-board display screen or instrument panel. When the actual opening of the trunk reaches the maximum door opening angle, the angle information on the display screen or instrument panel can continuously flash to warn the user, and at the same time, the vehicle trunk is controlled to stop opening.

[0058] It can be understood that the embodiments of the present application can control the opening of the vehicle trunk under the premise of safety by real-time detection of the actual opening angle of the vehicle trunk combined with the maximum opening angle, thereby avoiding the situation where the user opens the trunk excessively and hits an obstacle, thereby further improving the safety and reliability of the vehicle and greatly enhancing the user experience.

[0059] In step S103, a warning prompt is generated according to the maximum door opening angle, and at least one acoustic reminder device and / or at least one optical display device of the vehicle is controlled to provide a collision warning prompt inside and / or outside the vehicle according to the warning prompt.

[0060] When it is detected that the actual door opening angle reaches the maximum door opening angle, the embodiment of the present application can control the vehicle trunk to stop opening. At the same time, the vehicle can also be controlled to issue a collision warning reminder inside or outside the vehicle through devices such as horns or turn signals. The specific execution logic is as follows: Figure 3 As shown, the user is further reminded to ensure the overall safety of the vehicle.

[0061] Optionally, in one embodiment of the present application, before generating a warning prompt based on the maximum door opening angle, it also includes: extracting at least one material feature of surrounding obstacles; inputting at least one material feature into a pre-trained material recognition model to output the actual material of the surrounding obstacles; and correcting the maximum door opening angle based on the actual material.

[0062] It should be noted that before generating a warning prompt based on the maximum door opening angle, the embodiment of the present application can also extract the material characteristics of the surrounding obstacles and input them into the material recognition model, and then output the actual materials of the surrounding obstacles to correct the above-mentioned maximum door opening angle according to the actual materials.

[0063] Specifically, the embodiments of the present application can collect a large amount of relevant obstacle images or video data through high-definition cameras and other devices, and then use algorithms such as GLCM (Gray-Level Co-Occurrence Matrix) to process the above image data to extract the material characteristics of the surrounding obstacles. Further, the embodiments of the present application can use the cascade width learning algorithm to train the above material characteristics to build a material recognition model, so that the actual material of the surrounding obstacles can be obtained in real time. In addition, those skilled in the art can also use other deep learning methods to identify materials, which are not specifically limited here.

[0064] After obtaining the actual material of the above-mentioned obstacle, some physical properties corresponding to the obstacle material can be obtained, such as hardness, elasticity, mass, plasticity, etc. Therefore, the embodiments of the present application can judge whether the trunk can continue to be opened and the degree of opening based on parameters such as the elastic modulus of the above-mentioned material and the required opening degree of the vehicle trunk. For example, the smaller the elastic modulus of the material, the larger the angle at which the trunk can continue to be opened, thereby correcting the maximum opening angle of the trunk.

[0065] For example, when the actual material of the obstacle obtained by the above method is sponge, the vehicle can display parameters such as the elastic modulus of the sponge on the vehicle display screen, and use the vehicle system in combination with relevant parameters to calculate a correction value for the maximum opening angle of the trunk. The elastic modulus of the material and the above correction value can also be displayed on the vehicle display screen, and a request is sent to the user whether to correct the maximum opening angle. If the user accepts the request, the door controller controls the trunk to slowly open. During this process, the user can stop the opening process at any time by pressing the button in the car, or control the trunk to close, so as to avoid the trunk colliding with the obstacle.

[0066] It can be understood that the embodiments of the present application extract the material characteristics of the surrounding obstacles and construct a material recognition model to obtain the actual materials of the surrounding obstacles, so as to correct the maximum door opening angle according to the actual materials. This can not only meet the user's needs to properly open the trunk when there are obstacles while ensuring the safety of the vehicle, but also improve the user's usage experience and willingness, making the vehicle more humane and intelligent. At the same time, it protects the safety of opening the trunk of the vehicle to a certain extent, and greatly avoids damage to the trunk due to collision with obstacles.

[0067] Furthermore, by correcting the above-mentioned maximum door opening angle, a new maximum door opening angle is obtained. When the actual opening angle of the trunk reaches the corrected maximum door opening angle, the embodiment of the present application can generate a warning prompt to provide a collision warning reminder to the user.

[0068] For example, when the trunk of a vehicle reaches the corrected maximum opening angle, a danger icon can be displayed on the vehicle display or instrument panel, and the user can be reminded by voice, such as "The trunk has reached the maximum opening, please be careful to avoid collision with obstacles!", etc. The voice message can also be displayed on the vehicle display to remind the user in the car to the greatest extent. In addition, the vehicle turn signal can be controlled to flash continuously and the horn can be sounded to warn the user outside the vehicle. At the same time, the trunk of the vehicle can be controlled to stop opening or close to ensure the safety of the vehicle.

[0069] Therefore, the embodiments of the present application can issue warning information through one or more combinations of voice information, text information, and light information, thereby providing warning reminders inside and outside the vehicle, maximizing the attention of users and improving the efficiency of warnings. At the same time, if there are no obstacles around, there is no need to issue door opening angle warnings, and no reminders are required for passengers, thus avoiding excessive information affecting the passenger experience.

[0070] According to the vehicle trunk warning method proposed in the embodiment of the present application, the actual distance between the vehicle trunk and the surrounding obstacles is detected; when the actual distance is less than or equal to the preset safety distance, the maximum openable door angle of the vehicle trunk is calculated according to the actual distance; and a warning prompt is generated according to the maximum openable door angle, and at least one acoustic reminder device and / or at least one optical display device of the vehicle is controlled to issue a collision warning reminder inside and / or outside the vehicle according to the warning reminder. The present application determines the maximum openable door angle according to the distance between the trunk door and the surrounding obstacles to issue a collision warning, avoid collision when opening the trunk, thereby ensuring the safety of the vehicle and passengers, and greatly improving the user experience.

[0071] Next, the vehicle trunk warning device proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0077] Optionally, in one embodiment of the present application, the preset safety distance is obtained by the straight-line distance that the trunk door of the vehicle extends outward when the trunk door of the vehicle is opened to the maximum opening angle.

[0081] Optionally, in one embodiment of the present application, the warning device 10 for the trunk of the vehicle in the embodiment of the present application further includes: a third detection module and a second control module.

[0082] Among them, the third detection module is used to detect the actual opening angle of the vehicle trunk.

[0083] The second control module is used to control the vehicle trunk to issue a collision warning reminder and control the vehicle trunk to stop opening when it is detected that the actual door opening angle reaches the maximum door opening angle.

[0084] Optionally, in one embodiment of the present application, the warning device 10 for the trunk of a vehicle in the embodiment of the present application further includes: an extraction module, an output module and a correction module.
