[0075] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0076] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0077] Before describing the method for adjusting the image quality of a vehicle screen provided in an embodiment of the present application, the implementation environment involved in the embodiment of the present application is first described.

[0078] For example, Figure 1 This is a schematic diagram of an implementation environment of a method for adjusting the image quality of a vehicle screen provided in an embodiment of the present application, see Figure 1 , Figure 1 The device includes a vehicle 101, wherein the vehicle 101 may be provided with an onboard screen.

[0079] The in-vehicle screen is used to provide functions such as navigation, entertainment, and vehicle information interaction.

[0080] Optionally, the vehicle-mounted screen can be arranged in the front row of the vehicle 101, or in the front and rear rows of the vehicle 101, that is, the vehicle 101 can include the front screen 102, or the front screen 102 and the rear screen 103.

[0081] The front screen 102 may include, but is not limited to, an instrument screen, a passenger entertainment screen, a central control screen, and a passenger ceiling screen.

[0082] The instrument panel is located in front of the driver's seat and is set up to replace the mechanical pointer instrument of the transmission. It is mainly used to display vehicle speed, speed, fuel level, temperature, alarm prompts and other content.

[0083] The co-pilot entertainment screen is a display screen specially designed for the co-pilot seat, usually located in front of or above the co-pilot seat, for providing entertainment and other functions.

[0084] The central control screen is located in the center of the center console of the vehicle 101, and is mainly used to realize functions such as navigation, entertainment, air conditioning control, and menu settings (such as seat heating and steering wheel adjustment).

[0085] The co-pilot ceiling screen can be arranged on the roof of the co-pilot seat of the vehicle 101, and is mainly used for the co-pilot passenger to watch videos, listen to music or engage in other entertainment activities.

[0086] The rear screen 103 may include but is not limited to a ceiling screen and a seatback screen.

[0087] The ceiling screen is usually located in the center of the rear roof of the vehicle 101 and is mainly used for rear passengers to watch videos, listen to music or other entertainment activities.

[0088] The seatback screen may be located on the seatback of the front seat of the vehicle 101 and arranged facing the rear seat, mainly to provide relevant entertainment functions for the rear seat users.

[0089] The vehicle 101 is provided with a sleep mode. When the vehicle 101 is in the sleep mode, the seats, windows, lights and other equipment of the vehicle 101 can be controlled in linkage. For example, when the vehicle 101 is in the sleep mode, the front seats of the vehicle 101 can be laid down and connected with the rear seats to form a bed. In addition, the windows and lights of the vehicle 101 can be closed, or the windows are closed and the brightness and color of the lights are adjusted to the parameters set by the user.

[0090] In an embodiment of the present application, when the vehicle 101 is in sleep mode, the screen parameters of some of the above-mentioned vehicle screens can be adjusted, or the screen parameters of all the above-mentioned vehicle screens can be adjusted. The specific adjustment method is set according to the actual situation of the vehicle 101.

[0091] The application scenarios of the embodiments of the present application are further described.

[0092] For example, Figure 2 is a scene diagram of a method for adjusting the image quality of a vehicle screen provided in an embodiment of the present application, see Figure 2 , Figure 2 Including the above Figure 1 The central control screen 201 shown in the embodiment.

[0093] It should be understood that the vehicle includes multiple in-vehicle screens, and users in the vehicle can trigger the sleep mode through any one of the multiple in-vehicle screens. For example, users sitting in the back row can trigger the sleep mode through the rear screen.

[0094] like Figure 1 As shown, for example, if a user sitting in the passenger seat of the vehicle wants to rest and clicks the sleep mode start button set on the central control screen 201, the vehicle will enter the sleep mode. After the vehicle switches to the sleep mode, the seat of the vehicle can also be automatically laid flat to serve as a bed. In addition, the lights, windows, etc. in the vehicle will respond accordingly to provide the user with a good sleeping atmosphere.

[0095] In addition, after the vehicle switches to sleep mode, the vehicle screen that triggers the sleep mode can display the corresponding sleep-aiding animation, and the above-mentioned central control screen 201 can display the corresponding sleep-aiding animation to provide the user with a better sleeping atmosphere.

[0096] In sleep mode, users will relax and be completely unprepared for unsafe factors in the vehicle, so their safety awareness will be reduced. In this case, if the vehicle breaks down, the user may not know that the vehicle has broken down, which may seriously threaten the user's safety, so the user's safety cannot be guaranteed.

[0097] To this end, an embodiment of the present application provides a method for adjusting the image quality of a vehicle screen, which can be applied to a scenario in which the vehicle is in sleep mode.

[0098] Specifically, after receiving the operation of turning on the sleep mode of the vehicle, in response to the operation of turning on the sleep mode of the vehicle, when a fault alarm is detected in the vehicle, the alarm type of the fault alarm of the vehicle is first obtained. Then, based on the alarm type, the image quality of at least a part of the display area of ​​the vehicle screen that triggers the sleep mode is adjusted, so that the information associated with the fault alarm is displayed in the display area in a striking state. It should be understood that different alarm types have different adjustment strategies for the image quality of the vehicle screen.

[0099] In this way, when the vehicle is in sleep mode, if a vehicle fault alarm is detected, the image quality of at least a part of the display area of ​​the vehicle screen can be adjusted based on the alarm type, so that information related to the fault alarm can be prominently displayed in the display area, so that the vehicle screen can prompt the user that the vehicle has a fault alarm, so that the user can be informed of the vehicle fault in time and deal with it in time, which can improve the user's safety in sleep mode and improve the user experience at the same time.

[0100] The method for adjusting the image quality of the vehicle screen provided in the embodiment of the present application is explained in detail below.

[0101] Figure 3 1 is a flow chart of a method for adjusting the image quality of a vehicle screen provided in an embodiment of the present application. The method can be applied to a vehicle multimedia host (Head Unit, HUT). Figure 3 The method includes the following steps 301-303.

[0102] Step 301: In response to the operation of starting the sleep mode of the vehicle, the vehicle multimedia host obtains the alarm type of the fault alarm when detecting that the vehicle has a fault alarm.

[0103] The alarm type refers to the type of fault that occurs in the vehicle. In the embodiment of the present application, the alarm type is used to indicate the urgency of the fault alarm that exists in the vehicle. Optionally, the alarm type may include a non-emergency alarm and an emergency alarm.

[0104] As an implementation method, after the vehicle enters sleep mode, the ECU (Electronic Control Unit) can keep detecting whether the vehicle has a fault alarm. If the vehicle has a fault alarm, the ECU can send information about the fault alarm to the on-board multimedia host, so that the on-board multimedia host can be informed that the vehicle has a fault alarm.

[0105] Because users relax when they are resting, their safety awareness will be reduced. The vehicle may have various faults at any time, so when users are resting, they will not know the faults of the vehicle, so when the vehicle fails, it may affect the safety of users in some cases.

[0106] In this case, by continuously detecting whether the vehicle has a fault alarm after the vehicle enters sleep mode, and performing corresponding processing when a fault alarm is detected, the impact on user safety can be reduced, thereby improving user safety assurance.

[0107] Optionally, the operation of step 302 may be: when a fault alarm occurs in the vehicle, the vehicle multimedia host obtains a fault code of the fault in the vehicle; based on the fault code, obtains a corresponding alarm type from a second corresponding relationship and determines it as the alarm type of the fault alarm.

[0108] The fault code is used to uniquely identify the fault that occurs in the vehicle. It should be understood that different faults in the vehicle have different fault codes, and the fault in the vehicle has a unique fault code.

[0109] The second corresponding relationship refers to the corresponding relationship between the fault code and the alarm type, and the second corresponding relationship may include multiple fault codes and multiple alarm types, wherein for each fault code, there is a corresponding alarm type.

[0110] Optionally, the second corresponding relationship can be pre-set by a technician. For example, the technician can determine the corresponding alarm type according to the importance of the fault represented by the fault code (or the impact on user safety), so that the alarm type corresponding to different fault codes can be set.

[0111] For example, the following Table 1 is an example of the second corresponding relationship. Referring to Table 1, Table 1 includes multiple fault codes and alarm types, wherein the alarm types include emergency alarms and non-emergency alarms. In addition, each fault code has a corresponding alarm type. For example, if the fault of the vehicle is abnormal battery temperature, and the fault code of abnormal battery temperature is 331, then it is determined from the following Table 1 that the corresponding alarm type is an emergency alarm.

[0112] Table 1

[0113] Fault Codes Alarm Type 23 Non-emergency alarm 331 Emergency alarm 534 Non-emergency alarm …… ……

[0114] The embodiment of the present application only uses the above Table 1 as an example to exemplify the above second corresponding relationship, and does not constitute a limitation to the embodiment of the present application.

[0115] It is worth noting that in the embodiment of the present application, the vehicle-mounted screen may include an instrument screen and a ceiling screen.

[0116] In this case, when there is a fault alarm in the vehicle, the on-board multimedia host can display the fault icon or fault information of the fault alarm through the instrument screen; and display the target reminder information through the ceiling screen.

[0117] Fault information is used to indicate vehicle faults. For example, if the vehicle has an abnormal battery temperature alarm, a fault icon or related fault information of the abnormal battery temperature can be displayed on the instrument screen to remind the user that the vehicle has an abnormal battery temperature fault.

[0118] The target reminder message is used to remind the vehicle of a fault alarm. For example, the target reminder message can be "The battery temperature is abnormal, please check it in time" or "The battery temperature is abnormal, please stay away from the vehicle in time."

[0119] Since the user cannot know the fault of the vehicle when resting, and the user may face the ceiling screen when resting, when a fault alarm of the vehicle is detected, the corresponding reminder information can be displayed on the instrument screen and the ceiling screen.

[0120] In this case, by displaying the fault icon or fault information on the instrument screen and the target reminder information on the ceiling screen, the user can see the vehicle fault alarm at the first glance after opening his eyes when he is resting, and can see the fault in time on the instrument panel after he stands up, so that the user can more conveniently know the vehicle fault and thus improve the user experience.

[0121] Optionally, the in-vehicle multimedia host may control the vehicle to adjust the screen parameters of the in-vehicle screen to third screen parameters when the vehicle is in sleep mode.

[0122] The third screen parameter is a screen parameter suitable for the user to sleep. Optionally, the third screen parameter can be set in advance, for example, a technician can set it according to the user's sleep needs. In the embodiment of the present application, the screen parameter of the vehicle screen includes but is not limited to at least one of the color temperature, contrast, and brightness of the vehicle screen.

[0123] In this case, after turning on the sleep mode of the vehicle, the screen parameters of the vehicle screen are adjusted to the third screen parameters by controlling the vehicle, so that the screen parameters of the vehicle screen can be adjusted to screen parameters suitable for the user's sleep, thereby realizing the linkage control of the vehicle screen and the sleep mode, so that the vehicle screen can provide the user with a good sleeping atmosphere.

[0124] Optionally, the degree of light demand of other users during sleep can be obtained from a web page, an APP, or other channels, and then the third screen parameter can be determined based on the degree of light demand of most users during sleep. For example, the greater the degree of light demand during sleep, the greater the third screen parameter can be set; the smaller the degree of light demand during sleep, the smaller the third screen parameter can be set.

[0125] As an implementation method, the third screen parameter can be set by the user. For example, a sleep mode parameter configuration interface can be set on the vehicle screen, and the user can configure the parameters of each vehicle device through the sleep mode parameter configuration interface to achieve linkage control between the sleep mode and each vehicle device. Configuring the parameters of each vehicle device includes configuring the screen parameters of the vehicle screen.

[0126] For example, Figure 4 is a schematic diagram of a parameter configuration interface provided in an embodiment of the present application, see Figure 4 , Figure 4 The parameter configuration interface 401 includes a window configuration area 402, an air conditioning configuration area 403, and a vehicle screen configuration area 404. Figure 4 The contents that can be configured in the parameter configuration interface are merely exemplified and described, and may also include areas for configuring parameters of other vehicle-mounted devices, which is not limited in the embodiments of the present application.

[0127] like Figure 4 As shown, in the window configuration area 402, the user can set the degree of opening of the window by sliding. In the air conditioning configuration area 403, the user can set the parameters related to the air conditioning by sliding and clicking, such as setting the air conditioning temperature, wind speed and other parameters. In the vehicle screen configuration area 404, the user can configure the parameters of the vehicle screen such as color temperature, contrast, brightness, etc. by clicking and sliding.

[0128] In this case, when the vehicle turns on the sleep mode later, the screen parameters of the vehicle screen can be adjusted according to the parameters set by the user. In this way, the vehicle screen is displayed with the screen parameters required by the user in the sleep mode, so as to better meet the user's needs and thus improve the user experience.

[0129] It should be understood that, when the vehicle-mounted multimedia host does not receive an operation to start the sleep mode of the vehicle, the screen parameters of the vehicle-mounted screen can be controlled to remain as preset parameters.

[0130] The preset parameters may be the default screen parameters displayed on the vehicle screen set by the technicians at the factory.

[0131] Step 302: Based on the alarm type, the vehicle multimedia host adjusts the image quality of at least a portion of the display area of ​​the vehicle screen associated with the sleep mode, so that the information associated with the fault alarm is displayed in the display area in a striking state.

[0132] Image quality refers to a set of screen parameters of the vehicle screen, that is, image quality refers to multiple screen parameters of the vehicle screen, and adjusting the image quality of the display area is to adjust the screen parameters of the display area on the vehicle screen. In the embodiment of the present application, the image quality may include at least one of the brightness, color temperature, contrast, etc. of the vehicle screen.

[0133] The in-vehicle screen associated with the sleep mode refers to the in-vehicle screen that triggers the sleep mode, that is, the user triggers the sleep mode through this in-vehicle screen.

[0134] In this case, by adjusting the image quality of at least a part of the display area of ​​the vehicle screen based on the alarm type, and making the information related to the fault alarm prominently displayed in the display area where the image quality is adjusted, the vehicle screen can prompt the user that there is a fault alarm in the vehicle, so that the user can be informed of the vehicle fault in time and deal with it in time, which can improve the user's safety in sleep mode and at the same time improve the user experience.

[0135] It is worth noting that in an embodiment of the present application, different adjustments can be supported for screen parameters of different areas on the vehicle screen, that is, different screen parameters can be set for different areas. In this way, the picture quality of at least a part of the display area of ​​the vehicle screen can be adjusted.

[0136] Generally, the vehicle screen may include a backlight, which can adjust the brightness and other image quality of the vehicle screen by emitting light at different powers. In the embodiment of the present application, the backlight of the vehicle screen is divided into multiple independent areas, and the multiple independent areas are controlled separately, so that each area can independently adjust the brightness and other image quality.

[0137] Optionally, the operation of step 302 may be: when the alarm type is a non-emergency alarm, the vehicle multimedia host adjusts the image quality of the first display area of ​​the vehicle screen so that the information is displayed in a striking state in the first display area. When the alarm type is an emergency alarm, the vehicle multimedia host adjusts the image quality of the second display area of ​​the vehicle screen so that the information is displayed in a striking state in the second display area, and the second display area is the entire display area of ​​the vehicle screen.

[0138] It should be understood that the vehicle screen may include multiple partial display areas. The first display area is a partial display area of ​​the vehicle screen, for example, the first display area may be one of a partial display area, two partial display areas, etc., and the second display area is the entire display area of ​​the vehicle screen.

[0139] In this case, the vehicle multimedia host determines the display area to adjust the image quality according to the urgency of the alarm type. For example, in non-emergency situations, a smaller display area can be adjusted to display information related to the fault alarm, and in emergency situations, the entire display area can be adjusted to display information related to the fault alarm. In this way, the area adjustment is increased in the event of an emergency alarm, thereby attracting more user attention and enabling users to quickly learn of vehicle faults.

[0140] Optionally, the operation of step 302 may be: when the alarm type is a non-emergency alarm, the vehicle multimedia host adjusts the image quality of the display area to the first screen parameter; when the alarm type is an emergency alarm, the image quality of the display area is adjusted to the second screen parameter.

[0141] The first screen parameter is a screen parameter suitable for the user to read the fault alarm information in the sleep mode.

[0142] The second screen parameter is a screen parameter that can attract the user's attention to the vehicle-mounted screen.

[0143] The conspicuity corresponding to the second screen parameter is greater than the conspicuity corresponding to the first screen parameter. That is, when the vehicle screen is displayed with the second screen parameter, it has a higher conspicuity than when the vehicle screen is displayed with the first screen parameter.

[0144] Since non-emergency alarms are fault alarms that do not affect user safety, from the perspective of the urgency of handling, the user can choose not to handle the fault at this time, and can also handle it later. Therefore, the user can also see the information related to the fault alarm later. In this case, the display area can be controlled to display with the first screen parameters. Emergency alarms are fault alarms that have a greater impact on user safety. The user needs to immediately handle the fault or stay away from the vehicle, etc. Therefore, it is necessary to immediately attract the user's attention, so the image quality of the display area can be adjusted to the second screen parameters with higher eye-catchingness.

[0145] In this case, when the alarm type is a non-emergency alarm, the image quality of the display area is adjusted to the first screen parameter, so that when the vehicle fault does not affect the user's safety, the user's rest will not be disturbed, and only the information associated with the fault alarm will be clearly displayed in the display area so that the user can clearly see the information. When the alarm type is an emergency alarm, the image quality of the display area is adjusted to a second screen parameter with a higher degree of eye-catching, so that the image quality of the display area can be adjusted to be more eye-catching, so that the light emitted by the display area can play a role in attracting the user's attention, so that the user can be informed of the emergency fault of the vehicle in time and take corresponding measures, thereby improving user safety and user experience.

[0146] As an implementation method, the above two methods may be combined to adjust the image quality of the display area.

[0147] Specifically, when the alarm type is a non-emergency alarm, the vehicle multimedia host can adjust the picture quality of the first display area of ​​the vehicle screen to the first screen parameters; when the alarm type is an emergency alarm, the vehicle multimedia host can adjust the picture quality of the second display area of ​​the vehicle screen to the second screen parameters.

[0148] In this case, if the alarm type is a non-emergency alarm, the image quality of a portion of the display area of ​​the vehicle screen can be adjusted to the first screen parameter, so that the portion of the display area of ​​the vehicle screen can more clearly display information related to the fault alarm. If the alarm type is an emergency alarm, the image quality of the entire display area of ​​the vehicle screen can be adjusted to the second screen parameter, so that the entire display area of ​​the vehicle screen can more prominently display information related to the fault alarm.

[0149] The following first describes a specific strategy for adjusting the image quality of the display area by the vehicle multimedia host when the alarm type is a non-emergency alarm.

[0150] Among them, when the alarm type is a non-emergency alarm, the operation of the vehicle multimedia host adjusting the image quality of the display area to the first screen parameter can be: when the alarm type is a non-emergency alarm, the vehicle multimedia host obtains environmental information in the vehicle; based on the environmental information in the vehicle, determines whether there is a person in the vehicle who is awake; when there is a person in the vehicle who is awake, adjusts the image quality of the display area to the first screen parameter.

[0151] Optionally, the environmental information within the vehicle may be an image within the vehicle. Additionally, a camera may be installed inside the vehicle, and the image within the vehicle may be captured by the vehicle's internal camera.

[0152] In this case, when a fault alarm occurs in the vehicle, the on-board multimedia host first determines whether there is a person in the vehicle who is awake. If there is a person in the vehicle who is awake, the image quality of the display area is adjusted to the first screen parameter, so that the awake person can clearly see the information associated with the fault alarm, and it will not affect the person who is sleeping.

[0153] Optionally, in the case where there is no awake person in the vehicle, the image quality of the display area is controlled to remain unchanged.

[0154] Since the fault alarm at this time is a non-emergency alarm and will not affect the user's safety, the information related to the fault alarm can be prompted after the user wakes up.

[0155] In this case, by controlling the image quality of the display area to remain unchanged, when the vehicle failure will not affect the user's safety, if the people in the vehicle are not awake, the display area of ​​the vehicle screen can continue to maintain appropriate screen parameters for display, thereby ensuring that the user gets enough rest.

[0156] The operation of the vehicle multimedia host determining whether there is a person in a waking state in the vehicle based on the environmental information in the vehicle may include the following steps (1) to (4).

[0157] (1) The vehicle multimedia host obtains images of people in the vehicle from images in the vehicle.

[0158] Optionally, the person positioning may be performed on the image inside the vehicle to identify the position of the person in the image inside the vehicle; the area where the person is located in the image inside the vehicle is cropped to obtain an image of the person in the vehicle.

[0159] Among them, the method of locating people in the image inside the vehicle can be achieved through a target detection model. For example, the target detection model can be YOLO (You Only Look Once), RCNN (Region-based Convolutional Neural Networks), etc.

[0160] (2) The vehicle multimedia host performs posture recognition on the image of the person in the vehicle to determine whether the person in the vehicle has stood up.

[0161] In the embodiment of the present application, whether the person in the vehicle stands up refers to whether the upper body of the person in the vehicle leaves the seat surface, for example, it may be whether the person in the vehicle is in a sitting position.

[0162] For example, there is a situation where, when the vehicle is in sleep mode, its seat will be laid flat like a bed, so that the user can lie directly on it to rest when resting, so the upper body of the user is in contact with the seat surface when resting. Then, when the user stands up, his upper body will leave the seat surface, so whether the person in the vehicle stands up can refer to whether the upper body of the person in the vehicle leaves the seat surface.

[0163] For another example, there are multiple people in a vehicle, some of whom may be sleeping and some of whom may not. Then the people who are not sleeping may sit up.

[0164] In this case, by performing posture recognition on the image of the person in the vehicle to determine whether the person in the vehicle has stood up, it is possible to accurately determine whether the person in the vehicle is awake.

[0165] Optionally, the posture recognition of the image of the person in the vehicle can be performed through a posture estimation model, wherein the posture estimation model can be a deep learning model constructed based on a convolutional neural network and a recurrent neural network, for example, the posture estimation model can be PoseNet, DensePose, OpenPose, etc., which is not limited to the embodiments of the present application.

[0166] (3) When the posture recognition result shows that the person in the vehicle has stood up, the vehicle multimedia host determines that the person in the vehicle is awake; when the posture recognition result shows that the person in the vehicle has not stood up, the vehicle multimedia host performs eye state recognition on the image of the person in the vehicle to determine whether the person in the vehicle has opened his eyes.

[0167] When the posture recognition result is that the vehicle occupant stands up, it means that the upper body of the vehicle occupant has left the seat surface. At this time, it means that the vehicle occupant has sat up or is sitting up, and it can be determined that the vehicle occupant is awake.

[0168] When the posture recognition result shows that the person in the vehicle has not stood up, it means that the upper body of the person in the vehicle has not left the seat surface, that is, the person in the vehicle is still lying down. Therefore, in this case, the eye state of the image of the person in the vehicle can be recognized to further determine whether the person in the vehicle is still sleeping.

[0169] When judging the awake / sleeping state of a person in a vehicle, posture recognition is more likely to be based on contour features than eye state recognition. Therefore, from a technical point of view, posture recognition is easier to judge the awake / sleeping state of a person in a vehicle. Eye state recognition is more likely to be based on the detailed features of an image. From a technical point of view, it needs to judge the awake / sleeping state of a person in a vehicle through detailed features.

[0170] In this case, posture recognition is first used to determine whether the person in the vehicle is awake / asleep. If posture recognition is unable to determine whether the person in the vehicle is awake / asleep, eye state recognition is used to determine. This allows a simpler method to be used to determine whether the person in the vehicle is awake / asleep. When it is impossible to determine, eye state recognition is used. This allows the awake / asleep state of the person in the vehicle to be determined more accurately.

[0171] Among them, the vehicle-mounted multimedia host performs eye state recognition on the image of the person in the vehicle to determine whether the person in the vehicle has opened his eyes. The operation can be: the vehicle-mounted multimedia host performs feature encoding on the image of the person in the vehicle to obtain target image features; and classifies the target image features to obtain eye state recognition results.

[0172] The eye state recognition result may include whether the person in the vehicle has opened his eyes or not.

[0173] The vehicle-mounted multimedia host performs feature encoding on the image of the person in the vehicle to obtain the target image feature. The operation may be as follows: the vehicle-mounted multimedia host extracts the feature of the image of the person in the vehicle through a deep convolutional neural network to obtain the target image feature.

[0174] In the embodiment of the present application, the eye features are detailed features in the image of the person. Therefore, the eye features of the image of the person in the vehicle can be accurately extracted through a deep convolutional neural network, thereby obtaining accurate target image features, and further obtaining accurate eye state recognition results.

[0175] Among them, the operation of the vehicle multimedia host classifying the target image features and obtaining the eye state recognition result can be: classifying the target image features to obtain two reference recognition results and corresponding probabilities; and determining the reference recognition result with a higher probability among the two reference recognition results as the eye state recognition result.

[0176] The two reference recognition results may be that the person in the vehicle has opened his eyes and that the person in the vehicle has not opened his eyes, respectively. In addition, the probability that the person in the vehicle has opened his eyes and the probability that the person in the vehicle has not opened his eyes may also be included.

[0177] It should be understood that the reference recognition result with a greater probability among the two reference recognition results indicates that the classification result may be this reference recognition result. Therefore, the reference recognition result with a higher probability among the two reference recognition results can be determined as the eye state recognition result.

[0178] (4) When the eye state recognition result indicates that the occupant has opened his eyes, the vehicle multimedia host determines that the occupant is awake; when the eye state recognition result indicates that the occupant has not opened his eyes, the vehicle multimedia host determines that the occupant is asleep.

[0179] Optionally, when there is an awake person in the vehicle, the operation of adjusting the image quality of the display area to the first screen parameter by the vehicle multimedia host may be: the vehicle multimedia host obtains environmental information in the vehicle; based on the environmental information, determines the first screen parameter, and adjusts the image quality of the display area to the first screen parameter.

[0180] Here, the environmental information inside the vehicle may be the light intensity inside the vehicle.

[0181] The operation of the vehicle multimedia host determining the first screen parameter based on the environmental information may be as follows: the vehicle multimedia host obtains the corresponding screen parameter from the third corresponding relationship based on the light intensity in the vehicle and determines it as the first screen parameter.

[0182] The third corresponding relationship is the corresponding relationship between the illumination intensity and the screen parameter. The third corresponding relationship includes multiple illumination intensities and multiple screen parameters, wherein each illumination intensity has a corresponding screen parameter, and the screen parameter is suitable for the user to view the information associated with the fault alarm.

[0183] Optionally, the third corresponding relationship can be pre-calibrated by a technician. Specifically, by controlling the vehicle to be in different light intensities, and then adjusting the screen parameters of the vehicle screen, a screen parameter suitable for the user to view the information associated with the fault alarm is selected from the screen parameters adjusted multiple times as a screen parameter corresponding to the light intensity. In this way, screen parameters corresponding to different light intensities can be obtained, and these are screen parameters suitable for the user to view the information associated with the fault alarm corresponding to different light intensities.

[0184] It is worth noting that in the embodiment of the present application, it is also possible to determine whether there is a person in the vehicle who is awake by whether the vehicle-mounted multimedia host receives a shutdown operation for the sleep mode.

[0185] It should be understood that when an operation to close the sleep mode is received, it means that the user has clicked the close button of the sleep mode, and it can be determined that there is a person in the vehicle who is awake.

[0186] It should be noted that, in the case where the alarm type is a non-emergency alarm, by displaying the information associated with the fault alarm in the display area with adjusted image quality, the information associated with the fault alarm can be clearly displayed in the display area. In this way, a sober user can clearly see the vehicle fault information, or the user can see the vehicle fault alarm in time after waking up.

[0187] Next, when the alarm type is an emergency alarm, the specific adjustment strategy of the image quality of the display area by the vehicle multimedia host is described.

[0188] It should be noted that emergency alarm failures may threaten user safety. In this case, the user needs to know immediately that the vehicle has a fault and take corresponding measures. Therefore, when the alarm type is an emergency alarm, the measure to remind the user is mainly to attract the user as soon as possible.

[0189] It is worth noting that when the alarm type is an emergency alarm, the vehicle multimedia host can determine whether there is a conscious person in the vehicle; when there is a conscious person in the vehicle, the picture quality of the display area of ​​the vehicle screen can be adjusted to the second screen parameter, so that information related to the fault of the emergency alarm can be displayed in the display area.

[0190] If there is a person in the vehicle who is awake, it means that there is a person in the vehicle who can see the content displayed on the vehicle screen, so the image quality of the display area of ​​the vehicle screen can be adjusted. In this case, by adjusting the image quality of the display area of ​​the vehicle screen to the second screen parameter, the information associated with the fault alarm can be displayed very prominently in the display area, so that the awake person in the vehicle can see the information associated with the fault alarm displayed on the vehicle screen in time, and then can be informed of the vehicle fault in time.

[0191] It is worth noting that when the alarm type is an emergency alarm, in addition to adjusting the image quality of the display area to the second screen parameters, a target prompt sound can also be played.

[0192] The target prompt tone is a prompt tone corresponding to the fault of the vehicle, and the target prompt tone is used to remind the vehicle of the current fault. It should be understood that different faults can correspond to different prompt tones.

[0193] Since the failure of emergency alarms may endanger user safety, and users have less safety awareness in sleep mode, a warning sound will be a very effective way to inform users of vehicle failures as soon as possible.

[0194] In this case, by playing the target prompt sound while adjusting the image quality of the display area, users, whether sleeping or awake, can be informed of the vehicle failure and can take corresponding measures as soon as possible to avoid a greater threat to safety.

[0195] When the image quality includes at least one of color temperature, contrast, and brightness, the second screen parameter may include at least one of target color temperature, target contrast, and target brightness.

[0196] When the alarm type is an emergency alarm, the operation of the vehicle multimedia host adjusting the image quality of the display area to the second screen parameter may include at least one of the following.

[0197] First, the in-vehicle multimedia host adjusts the color temperature of the display area to the target color temperature.

[0198] The target color temperature is the highest color temperature that the car screen can achieve.

[0199] Color temperature is a standard for measuring the color of light sources. Common color temperatures range from warm tones (low color temperature, such as 2700K (Kelvin)) to cool tones (high color temperature, such as 6500K or higher). Usually, light with low color temperature is yellowish or orange, which is relatively soft. Therefore, in terms of conspicuousness, low color temperature is not very conspicuous and is not easy to attract strong visual attention. Light with high color temperature is blue or white, especially in a darker environment, and high color temperature will appear more dazzling and obvious, so it is more eye-catching.

[0200] When the alarm type is an emergency alarm, the fault of the vehicle will affect the safety of the user. In addition, when the image quality of the vehicle screen includes color temperature, in order to display the information associated with the fault alarm through the vehicle screen to remind the user, the color temperature of the display area can be adjusted to the target color temperature, so that the display area emits more eye-catching light, so as to attract the user's attention to the vehicle screen and see the information associated with the fault alarm.

[0201] Second, the vehicle multimedia host adjusts the contrast of the display area to a target contrast.

[0202] The target contrast is the maximum contrast that can be achieved by the vehicle screen.

[0203] Contrast refers to the difference in brightness between the brightest and darkest areas on the screen. High contrast means that black is blacker, white is whiter, black and white are in strong contrast, and colors are bright, so that the image has a stronger sense of hierarchy. From the perspective of eye-catchingness, it is more eye-catching and easy to attract visual attention. When the screen displays with low contrast, it lacks a sense of hierarchy and is usually not very eye-catching because the colors are not bright enough to attract attention.

[0204] When the alarm type is an emergency alarm, the vehicle fault will affect the user's safety. In addition, when the screen parameters of the vehicle screen include contrast, in order to display the information associated with the fault alarm through the vehicle screen to remind the user, the contrast of the display area can be adjusted to the target contrast, so that the display area emits more eye-catching light, so as to attract the user's attention to the vehicle screen and see the information associated with the fault alarm.

[0205] Third, the in-vehicle multimedia host adjusts the brightness of the display area to the target brightness.

[0206] The target brightness is the maximum brightness that the vehicle screen can achieve.

[0207] Generally, the higher the screen brightness, the more dazzling the light emitted by the screen. Therefore, if the alarm type is an emergency alarm, the brightness of the display area can be adjusted to the target brightness, so that the car screen emits more eye-catching light, so as to attract the user's attention to the car screen and see the information related to the fault alarm, thereby ensuring their own safety.

[0208] It should be noted that when the image quality of the vehicle screen includes at least one of color temperature, contrast, and brightness, the vehicle multimedia host can adjust the image quality of the display area in at least one of the above three ways. For example, when the image quality of the vehicle screen includes color temperature, contrast, and brightness, the image quality of the display area can be adjusted in a comprehensive manner using the above three ways.

[0209] In this case, it is equivalent to making the car screen always display the adjusted picture quality through at least one of the above methods, that is, controlling the car screen to always display with the highest color temperature, highest contrast and highest brightness.

[0210] Optionally, the image quality of the vehicle-mounted screen may also include flicker frequency.

[0211] In this case, when the alarm type is an emergency alarm, the vehicle multimedia host adjusts the brightness of the display area to the target brightness and the flashing frequency of the display area to the target flashing frequency, so that the display area flashes at the target brightness and target flashing frequency.

[0212] A flashing display refers to periodically changing the visible state of the display content, such as on / off.

[0213] In this case, that is, the display area of ​​the vehicle screen is controlled to flash at a target flashing frequency, and when the display area of ​​the vehicle screen is lit, it is displayed at a target brightness. This allows the display area of ​​the vehicle screen to flash and emit very eye-catching light, thereby stimulating the user's visual nerves, thereby achieving the purpose of quickly attracting the user's attention to the vehicle screen and seeing the information associated with the fault alarm.

[0214] Furthermore, when the vehicle-mounted multimedia host detects that a person in the vehicle is approaching the vehicle-mounted screen, it controls the display area to stop flashing and displays information associated with the fault alarm in the display area.

[0215] When a person in the vehicle is detected approaching the vehicle screen, it means that the user has been attracted by the flashing display of the vehicle screen and is about to view the vehicle screen. In this case, by controlling the display area to stop flashing, the user can clearly see the information associated with the fault alarm, so that the user can be informed of the fault of the vehicle in time, and then can deal with the fault in time to ensure his own safety.

[0216] Optionally, when the screen parameters of the vehicle screen include color temperature, contrast, brightness and flicker frequency, the vehicle multimedia host may also execute the following image quality adjustment strategy.

[0217] When the alarm type is an emergency alarm, the vehicle multimedia host can control the display area of ​​the vehicle screen to flash at a target color temperature, target contrast, target brightness and target flashing frequency.

[0218] In this case, it is equivalent to controlling the display area of ​​the car screen to flash first, and when flashing, the display area of ​​the car screen emits the strongest light that can be emitted. By flashing and emitting the strongest light at the same time, the user's visual nerves can be fully stimulated, thereby achieving the purpose of reminding the user.

[0219] Optionally, when the vehicle-mounted multimedia host detects an emergency fault alarm in the vehicle, it can adjust the image quality of the display area in at least one of the three methods mentioned above, and can also determine whether all occupants in the vehicle are awake within the target time length; if not all occupants in the vehicle are awake within the target time length, the vehicle-mounted screen is controlled to flash with the target color temperature, target contrast, target brightness and target flashing frequency.

[0220] The target duration can be set in advance, and the target duration can be set smaller.

[0221] In this case, it is equivalent to judging whether all occupants in the vehicle are awake in a short period of time. If not all of them are awake, the image quality of the on-board screen will be further adjusted to more visually stimulating parameters, so that users will pay attention to the faults in the vehicle and be reminded as soon as possible, thereby improving user safety assurance.

[0222] It is worth noting that when there is an awake person in the vehicle, the on-board multimedia host determines the target screen based on the position of the awake person; adjusts the image quality of at least a part of the display area of ​​the target screen so that the information associated with the fault alarm is displayed in this display area in a striking state.

[0223] The target screen is the in-vehicle screen closest to the awake person. For example, if the awake person is in the passenger seat, the target screen may be the passenger entertainment screen.

[0224] Consider a situation where the person who triggers the sleep mode is close to the vehicle screen associated with the sleep mode. If the person who is awake in the vehicle is not the person who triggered the sleep mode, when the screen associated with the sleep mode is adjusted, the person who is awake may not know that the information displayed on the screen is associated with the fault alarm.

[0225] For example, the screen that triggers the sleep mode is in the back row. When a vehicle breaks down, the screen in the back row that triggers the sleep mode is adjusted. At this time, the person who is awake is in the passenger seat. In this case, the user who is awake does not know the fault information displayed on the rear screen.

[0226] In this case, by adjusting the image quality of at least a part of the display area of ​​the target screen, the information associated with the fault alarm can be prominently displayed in the display area of ​​the target screen. Therefore, when a vehicle breaks down, awake personnel can always see the information related to the fault alarm and thus be informed of the vehicle breakdown in a timely manner, which is beneficial to personnel safety.

[0227] Optionally, when an emergency alarm occurs in the vehicle, the vehicle multimedia host can display the target reminder information on all the vehicle screens, so that the user can see the target reminder information on any screen, thereby allowing the user to more quickly learn that the vehicle has a fault alarm.

[0228] Optionally, when there is a person in the vehicle and the onboard multimedia host detects that the person in the vehicle has not been awake, a voice reminder message can also be output.

[0229] The voice reminder information is used to remind the user by voice that a fault alarm has occurred in the vehicle.

[0230] It is worth noting that when the vehicle-mounted multimedia host receives the operation to shut down the sleep mode, it can first respond to the operation to shut down the sleep mode and detect whether the vehicle's fault alarm disappears; if the vehicle's fault alarm does not disappear, the picture quality of the display area is kept unchanged as the second screen parameters.

[0231] When a sleep mode shutdown operation is received, it indicates that the user has triggered the sleep mode shutdown operation. Since there is a fault alarm in the vehicle at this time, it is necessary to determine whether the fault alarm disappears to determine whether to adjust the image quality of the display area.

[0232] If the vehicle fault alarm does not disappear, it means that there is still an emergency fault alarm in the vehicle, and the fault of the vehicle has a great impact on the safety of the user. Therefore, in this case, by keeping the image quality of the display area unchanged as the second screen parameter, the vehicle screen continues to alert the user.

[0233] It is worth noting that the vehicle screen image quality adjustment method provided in the embodiment of the present application can adjust the image quality of at least a portion of the display area of ​​the vehicle screen associated with the sleep mode accordingly based on the alarm type when a fault alarm occurs in the vehicle. Specifically, when the alarm type is a non-emergency alarm, since the current fault does not affect the safety of the user, the display area can be kept displayed with a quality suitable for the user to sleep when the people in the vehicle are not awake, and the image quality of the display area can be adjusted to screen parameters suitable for the user to read the information associated with the fault alarm when the people in the vehicle are awake. When the alarm type is an emergency alarm, the current fault has a greater impact on the safety of the user. By adjusting the display area of ​​the vehicle screen associated with the sleep mode to a more eye-catching quality, the purpose is to indirectly prompt the user to view the information associated with the fault alarm through the change of the image quality of the vehicle screen, so as to quickly evacuate the vehicle.

[0234] For ease of understanding, now combined Figure 5 The method for adjusting the image quality of a vehicle screen provided in an embodiment of the present application is exemplarily described. For example, Figure 5 is a flow chart of another method for adjusting the image quality of a vehicle screen provided by an embodiment of the present application. Figure 5 , Figure 5 The process includes the following steps 501 to 506.

[0235] Step 501: The sleep mode is turned on, and the vehicle multimedia host adjusts the screen parameters of the vehicle screen to the third screen parameters.

[0236] Step 502: The vehicle multimedia host determines whether there is a fault alarm in the vehicle. If a fault alarm is detected in the vehicle, the following step 503 is executed. If no fault alarm is detected in the vehicle, the process returns to step 501 to continue to keep the screen parameters as the third screen parameters.

[0237] Step 503: The vehicle multimedia host obtains the alarm type of the fault alarm. If the alarm type of the fault alarm is a non-emergency alarm, the following steps 504 to 505 are executed. If the alarm type of the fault alarm is an emergency alarm, the following step 506 is executed.

[0238] Step 504: The vehicle multimedia host determines whether there is a person in the vehicle who is awake. If there is no person in the vehicle who is awake, the process returns to step 501 to continue to keep the screen parameters of the vehicle screen as the third screen parameters. If there is a person in the vehicle who is awake, the process proceeds to step 505.
