Description

Technical Field

[0001] This application relates to the field of automotive electronics application technology, and in particular to a method, device, vehicle, and storage medium for controlling a vehicle's display screen. Background Technology

[0002] With the development of technology and the improvement of people's living standards, people have increasingly higher requirements for the intelligence of car cockpits. As the hub of human-computer interaction, the level of intelligence of in-vehicle displays reflects the overall intelligence level of the cockpit. At present, displays are mostly used as a display carrier, showing parameters, navigation information, and multimedia information during vehicle operation. The level of intelligent display is extremely low or even non-existent, which can no longer meet the needs of drivers in driving.

[0003] In related technologies, cameras can be used to monitor the driver and passengers, and the brightness of the current environment can be determined based on the monitored image data in order to adjust the brightness of the display screen.

[0004] However, among related technologies, displays that lack intelligent display perception can interfere with driving conditions to some extent. The displays cannot perform human-computer interaction, making it difficult to meet the driver's display needs when driving at high speeds. Furthermore, they cannot perceive the surrounding environment and the driver's driving status, which limits their capabilities and reduces the driver's driving experience, and urgently needs to be improved.

Furthermore, at high speeds, traditional displays cannot facilitate convenient human-machine interaction and fail to meet the driver's display needs.

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] The following description, with reference to the accompanying drawings, describes a vehicle display control method, device, vehicle, and storage medium according to embodiments of this application. Addressing the issues raised in the background section regarding related technologies where displays lacking intelligent display perception interfere with driving conditions, lack human-computer interaction, fail to meet the driver's display needs at high speeds, and cannot perceive the surrounding environment or the driver's driving state, thus limiting the driver's experience, this application provides a vehicle display control method. This method utilizes a camera to monitor the driver's state and surrounding environment in real time, enabling proactive reminders and intelligent display. Furthermore, it uses light sensing to adjust the display effect in real time, thereby improving the driver's experience. This solves the problems of related technologies where displays lacking intelligent display perception interfere with driving conditions, lack human-computer interaction, fail to meet the driver's display needs at high speeds, and lack perception of the surrounding environment and the driver's driving state, thus limiting the driver's experience.

[0032] Specifically, Figure 1 This is a flowchart illustrating a vehicle display screen control method provided in an embodiment of this application.

[0033] like Figure 1 As shown, the display screen control method of this vehicle includes the following steps:

[0034] In step S101, the system detects whether the vehicle has entered the display screen perception mode based on the vehicle's surrounding environment and the driver's current state.

[0035] It is understood that the display sensing mode in this application embodiment is a mode that automatically adjusts the display parameters and presented content by sensing the user's environment, behavior state and needs.

[0036] In actual implementation, this application embodiment can collect data on the surrounding environment from the external camera when the system starts up, and collect data on the driver's state from the camera located under the display screen, so as to obtain the vehicle's surrounding environment and the driver's current state, in order to detect whether the vehicle has entered the display screen perception display mode. The collected surrounding environment data can be transmitted to the display system through the WIFI channel. The display system analyzes the data and feeds back the analysis results on the driver's side display screen interface.

[0037] The embodiments of this application can monitor the driver's status and the surrounding environment in real time, thereby enabling proactive reminders and intelligent displays, which in turn improves driving safety and optimizes the driving experience.

[0038] Optionally, in one embodiment of this application, detecting whether the vehicle has entered the display screen perception mode based on the vehicle's surrounding environment and the driver's current state includes: acquiring at least one of the following information: the vehicle's surrounding environment, the driver's current state, vehicle speed, the driver's driving behavior, and weather; and detecting whether the vehicle has entered the intelligent perception display mode based on the at least one piece of information.

[0039] It is understood that the embodiments of this application can obtain the vehicle's surrounding environment through an external camera, obtain the driver's current state through a camera located under the display screen, and obtain vehicle speed data through a speed sensor.

[0040] As one possible implementation method, embodiments of this application can acquire information such as the vehicle's surrounding environment, the driver's current state, vehicle speed, driver's driving behavior, and weather, thereby detecting whether the vehicle has entered the intelligent perception display mode, further realizing proactive reminders and intelligent display, thereby improving driving safety and optimizing the driving experience.

[0041] In step S102, when the vehicle enters the display screen perception display mode, the light intensity data of the driver's location is collected, and the vehicle is judged to meet the preset display screen control conditions based on the light intensity data.

[0042] It is understood that the preset display screen control conditions in the embodiments of this application can be conditions that satisfy the application scenario, display content, and brightness of the display screen.

[0043] In actual implementation, when the system is started, this embodiment can collect light intensity data of the driver's location through a light sensor located under the display screen when the vehicle enters the display screen perception mode. Based on the light intensity data, it can determine whether the vehicle meets certain display screen control conditions. Based on the judgment result, the display screen can be controlled in a targeted manner to realize intelligent perception and active adjustment of the vehicle display, thereby improving the driver's driving experience.

[0044] It should be noted that the preset display screen control conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0045] In step S103, if the vehicle meets the preset display screen control conditions, the vehicle's display screen is controlled to perform a brightness adjustment action based on the light intensity data, and the driver's dangerous driving state is extracted from the driver's facial expressions and behavioral characteristics, so as to control the vehicle's display screen to perform a danger warning action based on the dangerous driving state.

[0046] It is understood that the brightness adjustment action in the embodiments of this application can be to brighten or darken the display screen.

[0047] In practical implementation, this application embodiment can adjust the brightness of the display screen based on light intensity data when the vehicle meets certain display screen control conditions. This ensures that the information on the display screen is clearly visible and does not cause glare under any lighting conditions, thereby reducing safety hazards caused by obstructed vision. This application embodiment can extract the driver's dangerous driving state from the driver's facial expressions and behavioral characteristics, and control the display screen to perform hazard warning actions based on the dangerous driving state. This includes displaying warning information, emitting sound or vibration alerts on the display screen to attract the driver's attention and prompt them to take safety measures.

[0048] This application's embodiments, through monitoring and adjustment, provide focused reminders for various driving conditions or problems that may occur during driving, improving the driving experience and potentially preventing accidents to some extent. Furthermore, this application, through subsequent data maintenance, possesses self-learning capabilities, can establish a cloud server, and relies on the cloud server to achieve real-time data interaction, continuously improving and refining its functionality.

[0049] It should be noted that the embodiments of this application establish a complete intelligent sensing display system, including functions such as in-vehicle intelligent display, intelligent sensing, light sensing, and active adjustment. The intelligent sensing display system includes the following design contents:

[0050] Hardware system design: design of light sensor and in-vehicle camera display, design of external camera, definition of transmission channel, and completion of hardware equipment design.

[0051] Database Design: 1. Drivers' driving habits and corresponding environmental handling strategies are stored in the database. The backend platform processes the real-time interactive data and provides prompts through the display interface; 2. The database is maintained and its functions are continuously improved.

[0052] User interface design: Users can perform CRUD operations on database information, interact with the server, and update system versions. The cloud server setup allows for real-time upgrades to the display system, cloud server maintenance, and self-learning capabilities.

[0053] The preset display screen control conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0054] Optionally, in one embodiment of this application, the driver's dangerous driving state is extracted from the driver's facial expressions and behavioral characteristics, and the display screen is controlled to perform a dangerous driving warning action according to the dangerous driving state. This includes: detecting whether the driver is in at least one dangerous driving state, such as fatigue, answering a phone call, or being distracted, based on facial expressions and behavioral characteristics; and controlling the display screen to display dangerous driving warning information to provide a dangerous driving reminder when the driver is in at least one dangerous driving state.

[0055] It is understood that the driver's facial expressions and behavioral characteristics in this application embodiment can be collected by a camera. Facial expressions may include eye contact, mouth shape, and furrowed brows, while behavioral characteristics may include the driver's head movements, hand movements, and body posture.

[0056] In actual implementation, this application embodiment can detect whether the driver is in a state of fatigue (such as dull eyes and frequent blinking), answering a phone call (such as holding the phone close to the ear), or distracted (such as eyes looking away from the front of the vehicle and frequently turning the head) and other dangerous driving states based on facial expressions and behavioral characteristics. This application embodiment can also perform driver identification. When the driver is in a dangerous driving state, the collected data is handed over to the controller for processing, and the display screen is controlled to display dangerous driving warning information to provide a dangerous driving reminder.

[0057] Optionally, in one embodiment of this application, controlling the display screen to perform a brightness adjustment action based on light intensity data includes: determining whether the display screen brightness is greater than a preset brightness threshold based on the light intensity data; if the display screen brightness is greater than the preset brightness threshold, adjusting the vehicle's display screen to a first target brightness, otherwise adjusting the vehicle's display screen to a second target brightness.

[0058] It is understood that the light intensity data in this application embodiment can be processed by the display system's built-in controller, and the result can be compared with the data in the controller; the first target brightness in this application embodiment can be to increase the brightness of the display screen, and the second target brightness can be to decrease the brightness of the display screen.

[0059] In actual implementation, this application embodiment can determine whether the brightness of the display screen is greater than a certain brightness threshold based on the light intensity data. If the brightness of the display screen is greater than a certain brightness threshold, it indicates that the ambient brightness is very bright, and the brightness of the display screen can be increased. If the brightness of the display screen is less than or equal to a certain brightness threshold, it indicates that the ambient brightness is very low, and the brightness of the display screen can be decreased.

[0060] This application embodiment can ensure a good driving experience for the driver through autonomous adjustment. Furthermore, before performing this action, the light intensity at the driver's position needs to be calibrated, and the calibration data is integrated into the display screen's controller. When the system receives data from the light sensor, it will actively determine and adjust accordingly.

[0061] It should be noted that the preset brightness threshold can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0062] Optionally, in one embodiment of this application, the method further includes: obtaining the driver's driving habits; determining the driver's personalized needs based on the driving habits; matching personalized content of the vehicle based on the personalized needs; and displaying the personalized content on the vehicle's display screen.

[0063] It is understood that the embodiments of this application may use vehicle-mounted sensors, cameras, GPS (Global Positioning System) and other devices to collect various data of the driver during the driving process, such as driving speed, acceleration, braking frequency, steering habits and common routes, to generate the driver's driving habits.

[0064] In actual implementation, the embodiments of this application can obtain the driver's driving habits, determine the driver's personalized needs based on the driving habits, match corresponding personalized content from the vehicle's infotainment system according to the personalized needs, such as specific music styles, radio programs, news categories, navigation settings and interface themes, and display the personalized content on the display screen for the driver to view and use in real time.

[0065] The embodiments of this application can obtain the driver's driving habits and determine their personalized needs based on these habits, thereby matching and displaying corresponding personalized content, which can significantly improve the driver's driving experience and satisfaction.

[0066] Specifically, it can be combined with Figures 2 to 7 As shown, the working principle of the vehicle display control method in this application embodiment is explained in detail with a specific example.

[0067] like Figure 2 As shown, the intelligent display perception system in this embodiment consists of a light sensor, in-vehicle and out-of-vehicle cameras, a display system, and user interface operation steps. The specific workflow is as follows: After the vehicle is started, the system starts to work normally, collecting data on the driver's state and the surrounding environment through the light sensor and image collector, transmitting the collected data to the display system for analysis, and the controller feeds back the analysis results to the display system, providing prompts or active adjustments on the display interface.

[0068] This process involves several aspects:

[0069] I. Working principle of a camera (e.g.) Figure 3 (As shown): The optical image of the scene generated by the Lens is projected onto the sensor surface. After photoelectric conversion into an analog electrical signal, noise reduction is performed, followed by A / D conversion to become a digital image signal. This signal is then processed by a digital signal processing chip before being output. The output signal from the external camera is transmitted to the display system via a Wi-Fi channel, while the signal from the under-screen camera interacts with the display system through a dedicated communication protocol.

[0070] II. Light sensors operate based on the photoelectric effect. This refers to the phenomenon where certain substances absorb light and convert it into electrical energy. The photoelectric effect can be divided into external and internal photoelectric effects; this system uses the external photoelectric effect. Under light illumination, electrons are emitted from the interior of a substance, generating electricity—this is the external photoelectric effect. The light sensor is an ambient light sensor, mainly composed of a projector and a receiver. It focuses ambient light and transmits it to the receiver via the projector. Based on the photoelectric effect, the receiver converts various light signals into corresponding electrical signals, which are then further processed into various switching and control actions to adjust the screen brightness.

[0071] Third, to minimize the size of this system, this application integrates all in-vehicle sensors into the display screen, achieving a highly integrated and miniaturized system. This application allows for openings in the display screen, placing the cabin detection camera and light sensor beneath the screen. External data is acquired through the openings in the screen, and the under-screen camera has excellent light envelope, enabling better acquisition of effective driver information.

[0072] IV. The control unit of this system is located in the display screen system and is responsible for data processing and the implementation of control actions.

[0073] V. The system has upgrade capabilities and can be upgraded via a cloud server. Upgrade process (e.g.) Figure 7 As shown in the image, during the upgrade, the system identifies the version information. If the version information does not match, it obtains the latest data from the cloud server, displays the data downloaded by the display system, and implements the upgrade.

[0074] VI. System's working strategy (e.g.) Figure 6 As shown below:

[0075] 1) The vehicle starts, and the system begins to work, as shown in the diagram. Figure 4 As shown.

[0076] 2) The controller collects data on the driver's status and the surrounding environment through light sensors and cameras. The controller processes the collected data: the light sensor data determines whether to adjust the display brightness, the in-vehicle camera data determines the driver's status, and the external camera data determines the surrounding environment.

[0077] 3) The system stops working after the vehicle is turned off.

[0078] like Figure 4 As shown, embodiments of this application may include the following steps:

[0079] Step S401: Start the vehicle.

[0080] Step S402: System startup.

[0081] Step S403: The interface displays a message indicating that the system is enabled.

[0082] Furthermore, such as Figure 5 As shown, embodiments of this application may include the following steps:

[0083] Step S501: Turn off the vehicle.

[0084] Step S502: System shutdown.

[0085] Step S503: The interface displays a message indicating that the system is shut down.

[0086] like Figure 6 As shown, embodiments of this application may include the following steps:

[0087] Step S601: System startup.

[0088] Step S602: Collect data.

[0089] Step S603: Data determination.

[0090] Step S604: Data determination.

[0091] In this embodiment, the display screen brightness is not adjusted when the conditions are not met, and is adjusted when the conditions are met.

[0092] Step S605: Data determination.

[0093] In this embodiment, data can be collected and judged by an in-vehicle camera. If the conditions are not met, the display interface will not provide a prompt; if the conditions are met, the display interface will provide a prompt.

[0094] Step S606: Data determination.

[0095] In this embodiment, data can be collected and judged by an external camera. If the conditions are not met, the display interface will not provide a prompt; if the conditions are met, the display interface will provide a prompt.

[0096] Furthermore, such as Figure 7 As shown, embodiments of this application may include the following steps:

[0097] Step S701: Report the current firmware version.

[0098] Step S702: Add the upgrade firmware in the cloud console.

[0099] Step S703: Determine if there is an upgrade requirement. If yes, proceed to step S704; otherwise, proceed to step S705.

[0100] Step S704: Send a firmware upgrade request to the device.

[0101] Step S705: Do not perform an upgrade.

[0102] Step S706: Send the firmware URL to the device.

[0103] Step S707: Download firmware via the URL according to the protocol.

[0104] Step S708: After downloading, perform a firmware upgrade.

[0105] Step S709: The cloud displays "Upgrade in progress".

[0106] Step S710: Upgrade successful.

[0107] Step S711: The cloud displays "Upgrade successful".

[0108] The vehicle display control method proposed in this application includes functions such as in-vehicle intelligent display, intelligent perception, light sensing, and active adjustment. It can monitor the driver's state and surrounding environment in real time via a camera, detecting these factors to provide proactive reminders and intelligent display. Light sensing can be used to adjust the display effect in real time, thereby improving the driver's driving experience. Through these monitoring and adjustments, various driving conditions or problems that may occur during driving are highlighted, improving the driving experience and potentially preventing accidents to some extent. Furthermore, this system can establish a cloud server, relying on it to achieve real-time data interaction and continuous improvement, thus enhancing its functionality. This solves the problems in related technologies where displays lacking intelligent display perception interfere with driving conditions, cannot perform human-computer interaction, fail to meet the driver's display needs at high speeds, and lack perception of the surrounding environment and driver's state, thus limiting the driving experience.

[0109] Next, with reference to the accompanying drawings, a vehicle display control device according to an embodiment of this application is described.

[0110] Figure 8 This is a schematic diagram of the structure of the vehicle display control device according to an embodiment of this application.

[0111] like Figure 8 As shown, the vehicle's display screen control device 10 includes: a detection module 100, a judgment module 200, and a control module 300.

[0112] Specifically, the detection module 100 is used to detect whether the vehicle has entered the display screen perception mode based on the vehicle's surrounding environment and the driver's current state.

[0113] The judgment module 200 is used to collect light intensity data at the driver's location when the vehicle enters the display screen perception display mode, and to determine whether the vehicle meets the preset display screen control conditions based on the light intensity data.

[0114] The control module 300 is used to control the brightness adjustment of the vehicle's display screen based on light intensity data when the vehicle meets the preset display screen control conditions, and to extract the driver's dangerous driving state from the driver's facial expressions and behavioral characteristics, so as to control the vehicle's display screen to perform a hazard warning action based on the dangerous driving state.

[0115] Optionally, in one embodiment of this application, the control module 300 includes a detection unit and a control unit.

[0116] The detection unit is used to detect whether the driver is in at least one dangerous driving state, such as fatigue, answering a phone call, or being distracted, based on facial expressions and behavioral characteristics.

[0117] The control unit is used to control the vehicle's display screen to show dangerous driving warning information when the driver is in at least one dangerous driving state, in order to provide a dangerous driving reminder.

[0118] Optionally, in one embodiment of this application, the control module 300 further includes a judgment unit and an adjustment unit.

[0119] The judgment unit is used to determine whether the brightness of the display screen is greater than a preset brightness threshold based on the light intensity data.

[0120] The adjustment unit is used to adjust the vehicle's display screen to a first target brightness when the display screen brightness is greater than a preset brightness threshold, and otherwise adjust the vehicle's display screen to a second target brightness.

[0121] Optionally, in one embodiment of this application, the detection module 100 includes an acquisition unit and a detection unit.

[0122] The acquisition unit is used to acquire at least one of the following information: the vehicle's surrounding environment, the driver's current state, the vehicle speed, the driver's driving behavior, and the weather.

[0123] The detection unit is used to detect whether the vehicle has entered the display screen's perception display mode based on at least one piece of information.

[0125] The acquisition module is used to acquire the driver's driving habits.

[0126] The determination module is used to determine the driver's personalized needs based on driving habits.

[0127] The display module is used to match personalized content to the vehicle according to individual needs and display the personalized content on the vehicle's display screen.

[0128] It should be noted that the foregoing explanation of the vehicle display control method embodiment also applies to the vehicle display control device of this embodiment, and will not be repeated here.

[0129] The vehicle display control device proposed in this application can monitor the driver's state and surrounding environment in real time through a camera. By detecting the driver's state and the surrounding environment, it can provide proactive reminders and intelligent displays. It can also adjust the display effect of the screen in real time through light sensing, thereby improving the driver's driving experience. This solves the problems in related technologies where displays lacking intelligent display perception interfere with driving conditions to some extent, cannot perform human-computer interaction, fail to meet the driver's display needs at high speeds, and lack the ability to perceive the surrounding environment and the driver's driving state, thus limiting the driver's experience.
