DETAILED DESCRIPTION
[0017] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0019] In daily life, when a vehicle is parked or in motion, there may be individuals inside that require special attention, such as children, the elderly, and pregnant women. The presence of these individuals may necessitate extra care from those outside the vehicle or from drivers of other vehicles.
[0020] Currently, vehicles typically alert drivers or passengers to the situation inside the vehicle through in-car alarm systems or simple audible warnings. For example, some vehicles are equipped with child safety lock alarm systems that sound an alarm when a door is accidentally opened. Additionally, some vehicles display simple information on the dashboard, such as "Child lock engaged" or "Door not properly closed." While these technologies improve vehicle safety to some extent, they primarily alert occupants and cannot directly convey information about the presence of a specific object inside the vehicle to those outside. For instance, when there are children inside, those outside cannot visually perceive the situation using existing technology; that is, current technology cannot effectively alert those outside to the presence of a target requiring special attention within the vehicle, which is a problem that urgently needs to be addressed.
[0021] In view of this, this application provides a method for displaying vehicle alert information, which can be applied to the vehicle's electronic controller. The vehicle is equipped with a rear-end display device. The method may include: in response to the vehicle alert information display function being activated, detecting whether a target object exists inside the vehicle; if a target object is detected inside the vehicle, determining the type of the target object, such as a child, an elderly person, or a pregnant woman; and sending a display command corresponding to the type to the rear-end display controller, instructing the rear-end display controller to display alert information corresponding to the type of target object on the vehicle's rear-end display device, thereby alerting people outside the vehicle to the presence of a target object of that type inside the vehicle.
[0022] Figure 1 This is a flowchart illustrating a method for displaying vehicle notification information according to an embodiment of this disclosure. This method can be executed by a computing device. The computing device may include, but is not limited to, devices such as in-vehicle equipment or vehicle controllers, and the vehicle is equipped with a rear-end display device.
[0023] like Figure 1As shown, the method provided in this embodiment includes the following steps: S101: In response to the vehicle alert information display function being turned on, detect whether there is a target object inside the vehicle.
[0024] The computing device can determine whether the vehicle's alert information display function is turned on. In response to the vehicle's alert information display function being turned on, it can detect whether there is a target object inside the vehicle. The target object may include children (including infants), the elderly, and pregnant women.
[0025] For example, when the vehicle is started, the computing device can read the on / off status of the vehicle prompt information display function from the storage unit of the vehicle system.
[0026] In some possible implementations, this switch state can be configured by the user through the vehicle system's settings interface and stored in the vehicle system's non-volatile memory.
[0027] The computing device can determine whether a switch is in an "on" state by checking its read status. If the switch is in an "on" state, the computing device confirms that the vehicle alert display function is enabled, indicating that it can proceed with the steps of detecting the presence of a target object and displaying alert information for that object. If the switch is in a "off" state, the computing device confirms that the function is not enabled and stops executing subsequent steps.
[0028] In some possible implementations, when the vehicle's alert display function is activated, the in-vehicle camera can be started to capture images, thereby determining whether a target object exists inside the vehicle based on the captured image data. It should be noted that this application embodiment can install at least one camera inside the vehicle. When there is only one camera, since the target object is generally located in the rear seat, the camera can be positioned to provide a clear view of the rear seats. When there are multiple cameras, they can be installed at different angles inside the vehicle, thus covering as many areas as possible within the vehicle, thereby improving the accuracy and comprehensiveness of target object detection.
[0029] S102: If the target object is detected inside the vehicle, determine the type of the target object.
[0030] If the computing device detects a target object inside the vehicle, it can determine the type of the target object, which can include children (including infants), the elderly, pregnant women, and pets, etc.
[0031] In some possible implementations, to more accurately identify the presence of target objects and the type of target objects, the acquired images can be processed using the following steps: The first step can be image preprocessing, where the computing device can perform preprocessing operations such as noise reduction and contrast enhancement on the acquired image to improve image quality and reduce the impact of environmental factors (such as changes in lighting) on the recognition results.
[0032] The second step involves feature extraction, detection, and classification of the preprocessed image data. Specifically, the computing device can use a pre-trained image recognition model (such as a convolutional neural network) to extract features of the target object from the image data. These features may include shape, color, and texture. These features are then used to detect the presence of the target object in the image data and to classify it.
[0033] In some possible implementations, the computing device can also combine multiple frames of image data to further confirm the existence of the target object and further determine the type of the target object through time series analysis, thereby reducing the probability of misjudgment.
[0034] In some possible implementations, radar can also be installed in the vehicle. The radar can detect subtle movements of the chest cavity and body contours to locate a living person and their position. The camera can perform facial and body posture analysis on the locked area to extract features such as age, height, and abdominal protrusion. The computing device can then fuse the two types of information and, through a pre-trained deep learning model, detect whether there is a target object inside the vehicle and the type of target object that can be detected.
[0035] This allows for accurate identification of the target object type regardless of the lighting conditions inside the vehicle, whether the seats are obstructing the view, or whether the person is stationary, thereby reducing the probability of misidentification.
[0036] S103: Send a display command of the corresponding type to the rear display controller, so that the rear display controller controls the display of prompt information corresponding to the type of the target object on the rear display device of the vehicle.
[0037] After determining the type of the target object, the computing device can send a display command of that type to the rear display controller. This display command can instruct the rear display controller to display a prompt message corresponding to the type of the target object on the vehicle's rear display device (e.g., a rear display screen or a display device within the vehicle's taillights; in this embodiment, a rear display screen is used as an example). The prompt message can be, for example, text and / or image information, such as... Figure 2 As shown ( Figure 2 The target audience is children, and the prompts include both text and images.
[0038] For example, a computing device can retrieve a prompt message corresponding to a target object of that type from a preset prompt message library.
[0039] For example, if the target object is identified as a child, the computing device can determine the corresponding prompt, such as "There is a child in the car, please take care of them." If the target object is identified as an elderly person, the computing device can determine the corresponding prompt, such as "There is an elderly person in the car, please take care of them." Furthermore, if the target object is identified as a pregnant woman, the computing device can determine the corresponding prompt, such as "There is a pregnant woman in the car, please drive carefully."
[0040] This alerts people outside the vehicle to the presence of the target object, thereby preventing potential collisions or inappropriate behavior.
[0041] In some possible implementations, in order to more prominently remind people outside the vehicle and other vehicles, and to ensure that the prompt information can be quickly understood, the prompt information in this embodiment can be in the form of a combination of text information and image information.
[0042] Taking a child as the target object as an example, the computing device can send a display command corresponding to the child to the rear display controller. The rear display controller then controls the display of text and image information corresponding to the child on the vehicle's rear screen. For example, the text message could be "There is a child in the car, please take care," and the image could be a picture of a child, a cartoon character, or a baby bottle. Figure 3 As shown, it should be noted that text information and image information can be displayed simultaneously, or the two can be switched at preset times. Those skilled in the art can set this according to actual needs, and no limitation is made here.
[0043] In some possible implementations, this embodiment can also detect the child's state based on the vehicle's state (e.g., it may include a started state, a stopped state, and a turned-off state).
[0044] For example, when the vehicle is running, the computing device can detect the child's initial state, whether the initial state is normal or asleep.
[0045] A normal state refers to a child being awake and comfortable in the car, without any obvious discomfort or danger. A sleeping state refers to a child being asleep in the car.
[0046] For example, when the vehicle is stationary or turned off, the computing device can detect the child's secondary state, such as being in a high-temperature state, a hypoxic state, or a state of being stranded.
[0047] "High temperature" refers to an excessively high temperature inside the vehicle, which may pose a threat to a child's health and requires immediate cooling measures. "Oxygen deficiency" refers to insufficient oxygen inside the vehicle, which may pose a threat to a child's health and requires immediate ventilation or other measures to ensure air circulation. "Left alone" refers to a situation where leaving a child alone in the vehicle for more than a threshold time may pose a safety risk, requiring alerting those outside the vehicle and taking appropriate measures. It should be noted that the threshold time can be set according to actual needs, such as ten minutes, and is not limited here.
[0048] After determining the child's state, the computing device of this application can send a display command corresponding to the child's first or second state to the rear display controller, so that the rear display controller controls the display of text information and / or image information corresponding to the child's first or second state on the rear display screen.
[0049] For example, taking the rear display controller controlling the display of text and image information corresponding to the child's first or second state on the rear display screen as an example, when it is determined that the child is in a normal state, a display command corresponding to the child's normal state can be sent to the rear display controller, so that the rear display controller controls the rear display screen to display the green text "There is a child in the car, please take good care of him / her" with a smiling child icon.
[0050] Once it is determined that the child is asleep, a display command corresponding to the child's sleeping state can be sent to the rear display controller, which will then control the rear display screen to show the blue text "Child is sleeping in the vehicle, please be quiet," along with an icon of a child sleeping with their eyes closed.
[0051] When it is determined that a child is in a high-temperature state, a display command corresponding to the child's high-temperature state can be sent to the rear display controller, which will then control the rear display screen to display the red text "Child in the vehicle is in a high-temperature environment, please pay attention to ventilation," along with a thermometer icon indicating the high temperature. The text and icon can be displayed in a flashing manner.
[0052] When it is determined that a child is in a state of oxygen deficiency, a display command corresponding to the child's state of oxygen deficiency can be sent to the rear display controller, which will then control the rear display screen to show the orange text "The child inside the vehicle is in a state of oxygen deficiency. Please ventilate immediately," along with an oxygen cylinder icon. The text and icon can be displayed in a flashing manner.
[0053] Once it is determined that a child is left in the vehicle, a display command corresponding to the child's status can be sent to the rear display controller. This will cause the rear display controller to control the rear display screen to show the yellow text "Child left in the vehicle for too long, please pay attention to safety," along with a timer icon. The text and icon can also be displayed in a flashing mode.
[0054] In some possible implementations, a child may be in multiple states simultaneously. This allows for the simultaneous display of multiple states. For example, if a child is detected to be in both a high-temperature and oxygen-deficient state while the vehicle is stationary or off, the computing device can send display commands corresponding to these states to the rear-end display controller. This allows the controller to display the corresponding text and / or image information on the rear-end display screen. Alternatively, a display command for a single state can be randomly sent to the rear-end display controller, causing it to display the corresponding text and / or image information on the rear-end display screen.
[0055] This embodiment can detect the specific state of the child inside the vehicle based on the vehicle's status or the child's condition (e.g., normal state, sleeping state, high temperature state, hypoxia state, or stagnation state), and display corresponding text and / or image information on the rear display screen accordingly. This provides a more accurate alert to people outside the vehicle regarding the child's actual condition. This targeted alert not only improves driving safety and reduces potential dangers to children caused by external factors, but also quickly draws the attention of people outside the vehicle in emergency situations (such as high temperature or hypoxia), enabling timely rescue measures to ensure the child's safety.
[0056] In this embodiment, if the vehicle is in the start-up state and a change in the state of the child inside the vehicle is detected, a target display command can be sent to the rear display controller. The rear display controller can then update the message on the rear display screen from "There is a child in the vehicle" to "The child in the vehicle is sleeping. Please keep quiet."
[0057] Such dynamic updates ensure that people outside the vehicle or drivers of other vehicles always have up-to-date information about the status of children inside the vehicle, so that appropriate measures can be taken to ensure the safety and comfort of children.
[0058] If no child is detected inside the vehicle, a stop display command can be sent to the rear display controller, which will then stop displaying the warning message on the rear screen. This means that when the in-vehicle camera and related sensors confirm the absence of a child, the computing device sends a corresponding command to the rear display controller to stop displaying any child-related warning messages on the rear screen. This function ensures the accuracy and real-time nature of the warning messages, avoids unnecessary reminders, and reduces misunderstandings or confusion for people outside the vehicle. In this way, the displayed content can be adjusted more intelligently based on the actual situation inside the vehicle, further improving the user experience.
[0059] In some possible implementations, the prompt message for the target object can be determined in advance based on user input.
[0060] For example, a computing device can acquire user input information and determine the content to be displayed for the prompt information corresponding to the target object of the target type based on the user input information.
[0061] The computing device can acquire user input information through the vehicle's infotainment system's user interface. This information may include user-defined prompts, display methods, or identifiers for the target object. The computing device can then determine the specific content to display for the prompt corresponding to the target object type (such as a child, pet, or valuable item). For example, when a user wants to customize the prompt for a child in the car, they can select "child" as the target object type through the infotainment system's user interface and then input specific content. For instance, the user might input the text "There is a child in the car, please drive carefully," and select a child icon as an auxiliary identifier. After acquiring this user input information, the computing device will associate this content with the target object of "child" to determine the corresponding prompt content to be displayed.
[0062] Finally, once the type of the target object is determined to be the target type, the computing device can send a display command for the target type to the rear display controller based on these user-defined contents. This allows the rear display controller to control the rear display screen to show the corresponding prompt information, ensuring that people outside the vehicle or other vehicles can see and understand what kind of target object is present inside the vehicle. This enhances the user's control over the displayed prompt information, thus better adapting to the needs and preferences of different users.
[0063] In some possible implementations, different types of target objects may be displayed with different priorities, with the highest priority type of target object being the first target object.
[0064] In some scenarios, there may be multiple types of target objects inside the vehicle at the same time. When there are multiple different types of target objects inside the vehicle at the same time, the system can control the display screen at the rear of the vehicle to show the prompt information corresponding to the first target object.
[0065] For example, the computing device can assign different display priorities to different types of target objects. These target objects may include, but are not limited to, children, the elderly, and pregnant women. When there are multiple target objects in the vehicle and these target objects belong to different types, the computing device can determine the display priority of the corresponding prompt information according to the type of the target object.
[0066] For example, pregnant women have a higher display priority than children, who in turn have a higher display priority than the elderly. Of course, those skilled in the art can set the display priority of the target object according to actual needs, and this is not limited here.
[0067] In this way, when multiple target objects of different types exist within the vehicle, the computing device determines the display priority of the corresponding prompt information based on the type of the target object. In this case, the computing device can send a display command corresponding to the first target object (i.e., the target object with the highest priority) to the rear-end display controller, causing the rear-end display controller to display the prompt information corresponding to the first target command. This ensures that pedestrians outside the vehicle or drivers of other vehicles notice the most important prompt information first, allowing them to take appropriate measures to ensure safety.
[0068] For example, if a child and a pregnant woman are both in the car, and the pregnant woman is designated as the primary target, the rear display screen can be controlled to prioritize showing the message corresponding to the pregnant woman, such as "There is a pregnant woman in the car, please take good care of her." This design ensures that the most important message is delivered first when multiple targets are present, thereby improving driving safety and user experience.
[0069] In this embodiment, in response to the vehicle warning information display function being enabled, the system detects whether a target object exists inside the vehicle. If a target object is detected, its type can be determined, such as a child, an elderly person, or a pregnant woman. A display command corresponding to this type can be sent to the rear display controller, instructing it to display a warning message corresponding to the target object type on the vehicle's rear display device. This alerts people outside the vehicle to the presence of such a target object, ensuring they are aware of the situation inside the vehicle and can take appropriate action, thus effectively improving driving safety.
[0070] For example, when a target (such as a child) is detected inside the vehicle, the rear display screen can show a message such as "There is a child in the vehicle, please take extra care." This design creates a warmer and more friendly traffic environment. In this way, it reminds drivers of other vehicles to pay more attention to children in their vehicles, such as reducing unnecessary honking to avoid startling children with loud horns, thus creating a quieter and more comfortable riding environment and further improving vehicle comfort.
