[0016] In a possible implementation manner of the first aspect, before the determining the target picture quality mode of the target vehicle-mounted screen according to the emotion type of the target person, the method further includes:

[0017] When the target vehicle-mounted screen is a roof display screen, the number of target persons is determined; wherein the target person is a rear seat occupant;

[0018] When the number of target persons is greater than one, whether the roof display screen meets the picture quality mode automatic switching condition is determined according to the emotion type of all target persons;

[0019] When the emotion type of all target persons is the same, it is determined that the roof display screen meets the picture quality mode automatic switching condition.

[0020] When the target vehicle-mounted screen is a roof display screen, the number of rear seat occupants is determined, when the number of rear seat occupants is greater than one, that is, there are multiple rear seat occupants, when the emotion type of all rear seat occupants is the same, the roof display screen meets the picture quality mode automatic switching condition, so that the target picture quality mode determined by the roof display screen according to the facial expression information of all rear seat occupants is more in line with the emotion type of all rear seat occupants, thereby reducing the differences among the passengers, enhancing the resonance, and avoiding the dissatisfaction of the passengers caused by frequent switching of the picture quality mode, so that the rear seat occupants have a better entertainment experience.

[0021] In a possible implementation manner of the first aspect, after the determining the number of target persons when the target vehicle-mounted screen is a roof display screen, the method further includes:

[0022] When the number of target persons is one, it is determined that the roof display screen meets the picture quality mode automatic switching condition.

[0023] When the target vehicle-mounted screen is a roof display screen, when the number of target persons is one, that is, there is one rear seat occupant, it is determined that the roof display screen meets the picture quality mode automatic switching condition, so that the roof display screen can automatically adjust and switch the target picture quality mode determined according to the facial expression information of the rear seat occupant, which is more in line with the emotion type of the target person and meets the needs of the target person in different scenarios.

[0024] In a possible implementation manner of the first aspect, before the determining the target picture quality mode of the target vehicle-mounted screen according to the emotion type of the target person, the method further includes:

[0025] When the target vehicle-mounted screen is an instrument panel display screen, a co-driver multimedia display screen, or a seatback display screen, it is determined that the target vehicle-mounted screen meets the picture quality mode automatic switching condition.

[0026] When the target vehicle-mounted screen is the instrument panel display screen, the co-driver multimedia display screen or the chair-back display screen, since the corresponding target person is at most one, the target vehicle-mounted screen is determined to meet the picture quality mode automatic switching condition, so that the instrument panel display screen, the co-driver multimedia display screen and the chair-back display screen can respectively determine the target picture quality mode according to the facial expression information of the target person, automatically adjust and switch, without manual operation, to provide better personalized interactive experience for the target person, better meet the emotional type of the target person, save time and effort, and be simple and fast, and improve the satisfaction of the target person.

[0027] In a possible implementation manner of the first aspect, in a case where the target vehicle-mounted screen meets the picture quality mode automatic switching condition, the target picture quality mode of the target vehicle-mounted screen is determined according to the emotional type of the target person, and the method comprises the following steps.

[0028] In a case where the target vehicle-mounted screen meets the picture quality mode automatic switching condition, if the emotional type of the target person is a happy emotion, the target picture quality mode of the target vehicle-mounted screen is determined to be a bright mode.

[0029] If the emotional type of the target person is an anxiety emotion, the target picture quality mode of the target vehicle-mounted screen is determined to be a soft mode.

[0030] If the emotional type of the target person is a fatigue emotion, the target picture quality mode of the target vehicle-mounted screen is determined to be an eye protection mode.

[0031] If the emotional type of the target person is a mind-wandering emotion, the target picture quality mode of the target vehicle-mounted screen is determined to be a navigation mode.

[0032] If the emotional type of the target person is a natural emotion, the target picture quality mode of the target vehicle-mounted screen is determined to be a standard mode.

[0033] In a case where the target vehicle-mounted screen meets the automatic switching condition of the quality mode, if the emotion type of the target person is the happy emotion, the target quality mode of the target vehicle-mounted screen is determined as the bright mode, if the emotion type of the target person is the anxious emotion, the target quality mode of the target vehicle-mounted screen is determined as the soft mode, if the emotion type of the target person is the fatigue emotion, the target quality mode of the target vehicle-mounted screen is determined as the eye protection mode, if the emotion type of the target person is the absent-minded emotion, the target quality mode of the target vehicle-mounted screen is determined as the navigation mode, and if the emotion type of the target person is the natural emotion, the target quality mode of the target vehicle-mounted screen is determined as the standard mode, so that the target quality mode of the target vehicle-mounted screen is more in line with the emotion type of the target person. Since the emotion type is determined according to the facial expression information of the target person, the switched target quality mode is more in line with the current mood and emotion of the target person, and manual switching of the quality mode of the target vehicle-mounted screen is not needed, thereby improving the visual experience of the target person.

[0034] In a possible implementation of the first aspect, the control of the target vehicle-mounted screen to switch to the target quality mode comprises:

[0035] In a case where the alarm signal is received, in response to the alarm signal, an alarm display area of the alarm signal on the target vehicle-mounted screen is determined according to the alarm signal.

[0036] According to the alarm display area, a quality mode switching area and a non-quality mode switching area of the target vehicle-mounted screen are determined.

[0037] The quality mode switching area of the target vehicle-mounted screen is controlled to switch to the target quality mode, and the non-quality mode switching area is controlled to switch to the standard mode.

[0038] When the target vehicle-mounted screen meets the automatic switching condition of the quality mode, the current quality mode of the target vehicle-mounted screen is inconsistent with the target quality mode, the target vehicle-mounted screen needs to be controlled to switch to the target quality mode, and if the alarm signal is received, the alarm display area of the alarm signal on the target vehicle-mounted screen is determined according to the alarm signal in response to the alarm signal. Since the alarm display area needs to alarm and remind the target person, if the alarm display area also switches the quality mode, the target person is likely to ignore the alarm and reminder. According to the alarm display area, the quality mode switching area and the non-quality mode switching area of the target vehicle-mounted screen are determined, the quality mode switching area of the target vehicle-mounted screen is controlled to switch to the target quality mode, and the non-quality mode switching area is controlled to switch to the standard mode, so that the alarm display area can not switch to the target quality mode, but switch to the standard mode, which can effectively remind the target person and effectively avoid the occurrence of the situation of ignoring the alarm and reminder.

[0039] In a possible implementation of the first aspect, before determining the target image quality mode of the target in-vehicle screen based on the emotion type of the target person, the method further includes:

[0040] Determining whether to issue a reminder notification based on the current image quality mode of the target vehicle screen to remind the target person whether to trigger an automatic image quality mode switching function;

[0041] In a case where the target person triggers the automatic switching function of the picture quality mode, in response to the triggering operation of the automatic switching function of the picture quality mode, it is determined that the target vehicle screen meets the automatic switching condition of the picture quality mode.

[0042] Based on the current picture quality mode of the target vehicle screen, it can be determined whether to issue a reminder notification to remind the target person whether to trigger the automatic switching function of the picture quality mode. When the target person triggers the automatic switching function of the picture quality mode, in response to the triggering operation of the automatic switching function of the picture quality mode, it is determined that the target vehicle screen meets the automatic switching conditions of the picture quality mode, so that the automatic switching function of the picture quality mode of the target vehicle screen can be triggered according to the user's instructions, thereby improving the target person's interactive experience satisfaction and the target person's visual preference matching.

[0054] In the following description, specific details are set forth in order to provide a thorough understanding of embodiments of the present application. However, persons of ordinary skill in the art will readily recognize that embodiments of the present application can be practiced without these specific details. In other instances, well-known structures, devices, circuits, and methods have not been described in detail in order to avoid obscuring the description of the present application.

[0055] It should be understood that, when used in the specification and the appended claims of the present application, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0056] It should also be understood that the term "and / or" used in the specification and the appended claims of the present application means any combination of one or more of the associated listed items and all possible combinations thereof, and includes these combinations.

[0057] The picture quality mode of the screen mainly refers to the color style of the screen, for example, a bright mode in which the picture quality of the screen is bright and full of vitality, a soft mode in which the picture quality of the screen is soft and warm, and the like. Since color has an important influence on people's emotions, the picture quality mode of the vehicle-mounted screen also influences the emotional state of the vehicle passenger. Different picture quality modes can create different atmospheres to meet the needs of the vehicle passenger in different emotional states, and by selecting a suitable picture quality mode, the emotional state of the vehicle passenger can also be adjusted.

[0058] As shown in Figure 2 , Figure 2 is a display interface schematic diagram of a picture quality mode of a vehicle-mounted screen provided by the prior art, which is a picture quality mode displayed by the vehicle-mounted screen. When the vehicle passenger feels tired or irritable, the vehicle passenger prefers to select a picture quality mode of a cold color tone such as blue and green, which plays a role of calming and soothing emotions. At this time, the vehicle passenger can manually switch the picture quality mode to a high-level mode by operating the vehicle-mounted touch screen. When the driver is absent-minded and needs to be refreshed, the driver prefers to select a picture quality mode of a warm color tone such as red and yellow to stimulate vitality. At this time, the driver can switch the vehicle-mounted touch screen to a lively mode to remind the driver to concentrate and reduce traffic accidents.

[0059] The vehicle-mounted screen on the vehicle is generally pre-provided with multiple picture quality modes, which can be autonomously selected by the vehicle passenger or the driver according to the emotional state or needs to realize the switching of the picture quality mode of the vehicle-mounted screen. However, the current switching of the picture quality mode of the vehicle-mounted screen is mainly realized by manual operation of the vehicle-mounted screen or a remote control device by the driver or the vehicle passenger, and cannot realize automatic switching of the picture quality mode according to the facial expression or emotional state of the vehicle passenger or the driver. Manual operation is easy to distract the attention of the driver and is easy to mistakenly touch other functions, further affecting the driving experience of the vehicle passenger.

[0060] To solve the above problems, an embodiment of the present application provides a picture quality mode control method of a vehicle-mounted screen, as shown in Figure 1 , Figure 1 is a flowchart of a picture quality mode control method of a vehicle-mounted screen provided by an embodiment of the present application, which comprises the following steps.

[0061] In step S11, the current picture quality mode of the target vehicle-mounted screen and the emotional type of the target person are acquired; wherein the target person is a person corresponding to the target vehicle-mounted screen.

[0062] In step S12, in the case that the target vehicle-mounted screen meets the automatic switching condition of the picture quality mode, the target picture quality mode of the target vehicle-mounted screen is determined according to the emotional type of the target person.

[0063] Step S13 : When it is determined that the current image quality mode of the target vehicle-mounted screen is inconsistent with the target image quality mode, the target vehicle-mounted screen is controlled to switch to the target image quality mode.

[0064] It should be noted that the vehicle is installed with an on-board terminal, which can be an integrated circuit that integrates multiple functional modules into a single chip and integrates AI emotion recognition software. It is a core processor, including calculation, control, graphics processing, image signal processing, digital signal processing, AI recognition and video encoding and decoding functions. It can monitor the driver or passengers in real time through the on-board DMS camera (Driver Monitoring System Camera) and identify the emotional state of the driver or passengers through the AI ​​emotion recognition software.

[0065] The on-board terminal can be an intelligent on-board screen, or it can be a host device connected to the on-board screen. Other devices on the vehicle can be controlled through the on-board terminal or the intelligent on-board screen, such as: turning on and off the aromatherapy, playing and stopping music, starting and turning off the massage function of the seat, etc. It can also realize the interaction function with the passengers, identify the passengers' instructions through voice, body language and other recognition methods, and execute them.

[0066] In-vehicle screens can include one or more of the following: a central control display, a roof display, an instrument panel display, a passenger multimedia display, a seatback screen, and an armrest screen. The image quality mode of these in-vehicle screens significantly impacts the passenger or driver's riding experience. By adjusting the image quality mode of these in-vehicle screens, the in-vehicle screens can be made more suitable for the passenger or driver, improving their comfort while riding in the vehicle.

[0067] Among them, the central control display screen and the co-pilot multimedia display screen are used to display the current vehicle surrounding conditions, current location, navigation route or entertainment video, etc. to the co-pilot passenger. The picture quality mode affects the visual experience of the co-pilot passenger. When the central control display screen is used as the target vehicle screen, the target person corresponding to the central control display screen is the co-pilot passenger.

[0068] The roof display screen (ceiling screen) is the core of the rear-seat entertainment system, providing rich audio-visual enjoyment for rear passengers. Its picture quality mode directly affects the visual experience of rear passengers during the journey. When the roof display screen is used as the target vehicle screen, the target person corresponding to the roof display screen is the rear passenger.

[0069] The instrument panel display is used to provide the driver with key information about vehicle operation. Its image quality mode directly affects the driver's visual experience when driving the vehicle. When the instrument panel display is used as the target vehicle screen, the target person corresponding to the instrument panel display is the driver.

[0070] The chair back screen is used to provide video "picture-in-picture" function, gesture control screen function, video cache function, etc. for the rear passengers, and its quality mode also affects the riding experience of the passengers. When the chair back screen is the target vehicle screen, the target passengers corresponding to the chair back screen are the rear passengers facing the chair back screen.

[0071] The armrest screen is used to control the second row of seats, including controlling the air conditioner, seats, and aromatherapy functions in the vehicle, and its quality mode has little effect on the target passengers. When the armrest screen is the target vehicle screen, the target passengers corresponding to the armrest screen are the passengers sitting on the seats of the armrest screen.

[0072] The vehicle terminal can obtain the current quality mode of the target vehicle screen in real time through the communication connection with the vehicle screen. The vehicle terminal also pre-stores the corresponding relationship between the quality mode of the vehicle screen and the emotion type of the passengers. For example, when the emotion type of the passengers is happy, the quality mode of the vehicle screen that the passengers want to watch is bright mode; when the emotion type of the passengers is anxious, the quality mode of the vehicle screen that the passengers want to watch is soft mode.

[0073] As shown in Figure 3 , the flowchart of the quality mode switching method of the vehicle screen provided by another embodiment of the present application is shown in Figure 3 The vehicle DMS camera obtains the facial expression information of the target passengers in real time, extracts the user emotion features of the target passengers, and obtains the emotion type of the target passengers based on the AI emotion recognition algorithm through the integrated AI emotion recognition software.

[0074] It should be noted that the AI emotion recognition software can be obtained after training and optimization of many training samples. Each training sample includes facial expression information of the training personnel and its corresponding real emotion type. After training and optimization, the AI emotion recognition software can quickly and accurately identify the emotion type of the target passengers according to the obtained facial expression information of the target passengers. For example, the identified emotion type of the target passengers is anxious, tired, etc.

[0075] Since the vehicle screen exists a situation that the target person does not want to automatically switch the quality mode of the vehicle screen when playing special picture information, the quality mode automatic switching condition is set in advance, the quality mode automatic switching function is started when the target vehicle screen meets the quality mode automatic switching condition, at this time, the target vehicle screen is automatically switched according to the emotion type of the target person. When the target vehicle screen does not meet the quality mode automatic switching condition, the quality mode automatic switching function is closed, at this time, the target vehicle screen is not automatically switched according to the emotion type of the target person.

[0076] It should be noted that the quality mode automatic switching condition can be that the current quality mode of the target vehicle screen meets a specific requirement, or the information content displayed by the target vehicle screen is not the pre-set information content (such as alarm information), or the set vehicle driving state, or the set driving time period, and the embodiment does not make specific settings.

[0077] When the target vehicle screen meets the quality mode automatic switching condition, the quality mode automatic switching function is started, at this time, the target quality mode corresponding to the target vehicle screen is determined according to the emotion type of the target person through the pre-stored corresponding relationship between the quality mode of the vehicle screen and the emotion type of the corresponding vehicle passenger. The target quality mode is the quality mode that the target person wants to watch. As shown in Figure 3 Different emotion types correspond to screen quality modes, which are target quality modes.

[0078] In an optional example, when the target vehicle screen is a roof display screen, if there are multiple rear passengers, one of them is designated as the target person, and it is determined that the roof display screen meets the quality mode automatic switching condition.

[0079] It is judged whether the current quality mode of the target vehicle screen is consistent with the target quality mode, when the current quality mode of the target vehicle screen is not consistent with the target quality mode, it indicates that the current quality mode of the target vehicle screen is not the quality mode that the target person wants to watch, at this time, the quality mode of the target vehicle screen is automatically switched from the current quality mode to the target quality mode, meeting the viewing demand of the target person.

[0080] In an optional example, the vehicle terminal can also be communicatively connected to other devices, and when the mood type of the target person changes, the linkage strategy of the devices can be realized by controlling the other devices. For example, when the mood type of the target person is happy mood, the picture quality mode of the target vehicle screen is switched to the bright mode corresponding to the happy mood, at this time, the picture quality will be vivid and bright, full of vitality, and at the same time, the linkage strategy is used to control the popular music to be played, so that the mood of the target person is better. When the mood type of the target person is anxiety mood, in order to alleviate the anxiety mood of the target person, the picture quality mode of the target vehicle screen is switched to soft mode, because the picture of soft mode is warm color and the picture quality is soft, which can help the target person to relax, and at the same time, the linkage strategy is used to open the incense and play the soothing music, so that the nervous mood of the target person is relaxed, and the target person has a better driving experience.

[0081] When the target vehicle screen does not meet the automatic switching condition of the picture quality mode, the automatic switching function of the picture quality mode is closed, at this time, the target person can switch the picture quality mode of the target vehicle screen through manual operation, voice interaction, gesture interaction and the like.

[0082] It can be understood that the technical scheme provided by the embodiment can obtain the current picture quality mode of the target vehicle screen and the mood type of the target person, because the target person is the person corresponding to the target vehicle screen, so when the facial expression information of the target person using the target vehicle screen changes, the mood type of the target person can be recognized in time, and then the target picture quality mode of the target vehicle screen is determined according to the mood type of the target person, when the current picture quality mode of the target vehicle screen is inconsistent with the target picture quality mode, the target vehicle screen is controlled to switch to the target picture quality mode, so that the target picture quality mode of the target vehicle screen is more suitable for the mood type of the target person, the function of automatically completing the picture quality mode switching according to the mood type of the target person is realized, so that the target person does not need to manually operate the target vehicle screen to switch the picture quality mode, the probability of mistakenly touching other functions is reduced, the driving comfort of the target person is improved, and the technical problem that the operation is inconvenient and other functions are easily mistaken in the prior art caused by manually switching the picture quality style mode is effectively solved, so that the experience of the driver or the passenger is poor.

[0083] In a possible implementation, because the functions of the vehicle screens are different, the corresponding target persons can also be different, when the target vehicle screen is the central control display screen, in step S12, the target picture quality mode of the target vehicle screen is determined according to the mood type of the target person, and before that, whether the central control display screen meets the automatic switching condition of the picture quality mode can be determined by the following method:

[0084] When the target vehicle-mounted screen is the central control display screen, the opening state of the navigation system is acquired; whether the central control display screen meets the automatic switching condition of the quality mode is determined according to the opening state of the navigation system; in the case where the opening state of the navigation system is not opened, it is determined that the central control display screen meets the automatic switching condition of the quality mode; in the case where the opening state of the navigation system is opened, it is determined that the central control display screen does not meet the automatic switching condition of the quality mode.

[0085] Specifically, the central control display screen can display the current vehicle surrounding situation, the current positioning or the navigation route for the driver in combination with external cameras or radars and the like, and can also play audio and video for the driver or the passenger by connecting a mobile phone or a vehicle-mounted multimedia playing device, and the quality mode of the central control display screen also affects the visual experience of the driver or the passenger.

[0086] When the target vehicle-mounted screen is the central control display screen, if the navigation system of the vehicle is in use, the central control display screen will display navigation information or driving related information, at this time, if the quality mode of the central control display screen is automatically switched, it may cause the driver to not clearly see the navigation information on the central control display screen, thereby affecting the driving safety of the driver.

[0087] The vehicle-mounted terminal is in communication connection with the navigation system of the vehicle, and can acquire the opening state of the navigation system in real time or acquire the signal that the navigation system has been opened or not opened in response to the opening or closing operation of the navigation system.

[0088] According to the opening state of the navigation system, whether the central control display screen meets the automatic switching condition of the quality mode is determined. When the opening state of the navigation system is opened, at this time, the navigation system is in the opened state, the central control display screen displays the driving related information of the navigation system, such as navigation or 360 video, at this time, the central control display screen does not meet the automatic switching condition of the quality mode, that is, the central control display screen cannot realize the automatic switching of the quality mode.

[0089] When the opening state of the navigation system is not opened, at this time, the navigation system is in the unopened state, the driver does not need to check the information on the central control display screen, and the co-driver passenger can entertain through the central control display screen, at this time, the central control display screen meets the automatic switching condition of the quality mode, that is, the central control display screen can determine the target quality mode of the central control display screen according to the emotional type of the co-driver passenger, and when the current quality mode of the central control display screen is inconsistent with the target quality mode, the central control display screen is controlled to switch to the target quality mode.

[0090] It should be noted that the central control display screen can also be switched according to the quality mode of the co-driver multimedia display screen to the quality mode consistent with the co-driver screen.

[0091] It can be understood that, in the case that the navigation system is not turned on, the central control display screen meets the automatic switching condition of the picture quality mode, so that the central control display screen is automatically switched to the target picture quality mode according to the mood type determined by the facial expression information of the target person, and manual operation of the target person is not required, thereby effectively avoiding distraction of the driver or the front passenger, and in the case that the opening state of the navigation system is turned on, it is determined that the central control display screen does not meet the automatic switching condition of the picture quality mode, so that the navigation system can continuously maintain the original picture quality mode for display, and the current picture quality mode is not automatically replaced due to the facial expression information of the target person.

[0092] In a possible implementation, when the target vehicle-mounted screen is a roof display screen, in step S12, the target picture quality mode of the target vehicle-mounted screen is determined according to the mood type of the target person. Before that, whether the roof display screen meets the automatic switching condition of the picture quality mode can be determined by the following method:

[0093] When the target vehicle-mounted screen is a roof display screen, the number of target persons is determined; wherein the target person is a rear passenger; when the number of target persons is greater than one, whether the roof display screen meets the automatic switching condition of the picture quality mode is determined according to the mood type of all target persons; when the mood types of all target persons are the same, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode.

[0094] Specifically, the roof display screen (ceiling screen) is the core of the rear entertainment system, and provides rich audio and video entertainment, video playback and other functions for the rear passengers through wireless projection, Internet access, car machine control and other input pictures. The picture quality mode of the roof display screen directly affects the visual experience of the rear passengers during the journey. The target person corresponding to the roof display screen is the rear passenger.

[0095] When there are multiple rear passengers, if the mood types of multiple people are not completely the same, or the mood types of multiple people change at different times, there is a situation that there are multiple different picture quality modes corresponding to the same time. At this time, it is not possible to determine a unique target picture quality mode, and the roof display screen cannot automatically switch the picture quality mode of the roof display screen according to the mood type of the rear passenger.

[0096] The number of rear passengers is determined, and when the number of rear passengers is greater than one, for example, there are three rear passengers, whether the roof display screen meets the automatic switching condition of the picture quality mode is determined according to the mood type of all rear passengers.

[0097] When the facial expression information of all the rear passengers is similar, and the emotion type of all the rear passengers is the same, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode. According to the unique emotion type of the rear passengers, the target picture quality mode of the roof display screen is determined. When it is determined that the current picture quality mode of the roof display screen is inconsistent with the target picture quality mode, the roof display screen is controlled to switch to the target picture quality mode.

[0098] When the facial expression information of any two of the rear passengers is not similar, and the emotion type of any two of the rear passengers is not the same, it is determined that the roof display screen does not meet the automatic switching condition of the picture quality mode, and the roof display screen cannot be directly controlled to automatically switch the picture quality mode.

[0099] It can be understood that when the target vehicle screen is the roof display screen, the number of rear passengers is determined. When the number of rear passengers is greater than one, that is, there are multiple rear passengers, when the emotion type of all the rear passengers is the same, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode. The target picture quality mode of the roof display screen determined according to the facial expression information of all the rear passengers is more in line with the emotion type of all the rear passengers, so that the passengers reduce differences, enhance resonance, and avoid dissatisfaction of the passengers caused by frequent switching of the picture quality mode, so that the rear passengers have a better entertainment experience.

[0100] In a possible implementation, when the target vehicle screen is the roof display screen, after the number of target passengers is determined, when the number of target passengers is one, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode.

[0101] Specifically, after the number of rear passengers corresponding to the roof display screen is determined, when the number of rear passengers is one, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode. The rear passenger is the target passenger. The emotion type can be determined according to the facial expression information of the rear passenger, and the target picture quality mode is determined according to the emotion type. When the current picture quality mode of the roof display screen is inconsistent with the target picture quality mode, the roof display screen is controlled to switch to the target picture quality mode, so as to realize the automatic switching of the picture quality mode of the roof display screen.

[0102] It can be understood that when the target vehicle screen is the roof display screen, when the number of target passengers is one, that is, the number of rear passengers is one, it is determined that the roof display screen meets the automatic switching condition of the picture quality mode, so that the roof display screen can automatically adjust and switch according to the target picture quality mode determined according to the facial expression information of the rear passenger, which is more in line with the emotion type of the target passenger and meets the needs of the target passenger in different scenarios.

[0103] In a possible implementation, in step S12, the target picture quality mode of the target vehicle-mounted screen is determined according to the emotion type of the target person. Before that, whether the target vehicle-mounted screen meets the picture quality mode automatic switching condition can be determined by the following method: when the target vehicle-mounted screen is the instrument panel display screen, the co-driver multimedia display screen, or the seatback display screen, it is determined that the target vehicle-mounted screen meets the picture quality mode automatic switching condition.

[0104] Specifically, when the instrument display screen is the target vehicle-mounted screen, the instrument display screen is used to display vehicle state information or fault alarm conditions, and provides the driver with key information of vehicle operation, helping the driver to understand whether the vehicle is running normally in time, and the picture quality mode directly affects the driver's visual experience when driving the vehicle. The driver is the target person corresponding to the instrument display screen.

[0105] When the instrument display screen meets the picture quality mode automatic switching condition, the emotion type of the driver can be determined according to the facial expression information of the driver, the target picture quality mode of the instrument display screen is determined according to the emotion type of the driver, and when the current picture quality mode of the instrument display screen is different from the target picture quality mode, the picture quality mode of the instrument display screen is switched to the target picture quality mode. Or when the emotion type of the driver changes, the picture quality mode of the instrument display screen is controlled to be switched to the target picture quality mode corresponding to the changed emotion type.

[0106] When the co-driver multimedia display screen is the target vehicle-mounted screen, the co-driver multimedia display screen is used to provide entertainment and information display for the co-driver, and can also be used to adjust the volume, switch songs, and view navigation information, and the picture quality mode directly affects the riding experience of the co-driver, and the co-driver is the target person corresponding to the co-driver multimedia display screen.

[0107] When the co-driver multimedia display screen meets the picture quality mode automatic switching condition, the emotion type of the co-driver can be determined according to the facial expression information of the co-driver, the target picture quality mode of the co-driver multimedia display screen is determined according to the emotion type of the co-driver, and when the current picture quality mode of the co-driver multimedia display screen is different from the target picture quality mode, the picture quality mode of the co-driver multimedia display screen is switched to the target picture quality mode. Or when the emotion type of the co-driver changes, the picture quality mode of the co-driver multimedia display screen is controlled to be switched to the target picture quality mode corresponding to the changed emotion type of the co-driver.

[0108] When the chair back screen is the target vehicle screen, the rear passengers can realize seat back adjustment, ventilation adjustment, heating start, massage start and other functions through the chair back screen, and can also realize vehicle air conditioning adjustment, music playing, volume adjustment, atmosphere lamp light adjustment, window adjustment, fragrance concentration adjustment, and the like. In addition, some chair back screens also support video "picture-in-picture" function, gesture control screen function, video cache function and the like, and the picture quality mode also affects the riding experience of the passengers. Since the chair back screen is directed to the rear passengers, the rear passengers corresponding to the chair back screen are the target passengers corresponding to the chair back screen.

[0109] When the chair back screen meets the picture quality mode automatic switching condition, the emotion type of the rear passenger corresponding to the chair back screen can be determined according to the facial expression information of the rear passenger, the target picture quality mode of the chair back screen is determined according to the emotion type of the rear passenger, and the picture quality mode of the chair back screen is switched to the target picture quality mode when the current picture quality mode of the chair back screen is different from the target picture quality mode. Or when the emotion type of the rear passenger changes, the picture quality mode of the chair back screen corresponding to the rear passenger is switched to the target picture quality mode corresponding to the changed emotion type of the rear passenger.

[0110] It can be understood that when the target vehicle screen is the instrument panel display screen, the co-driver multimedia display screen or the chair back display screen, since the target passengers corresponding thereto are at most one, the target vehicle screen is determined to meet the picture quality mode automatic switching condition, so that the instrument panel display screen, the co-driver multimedia display screen and the chair back display screen can respectively determine the target picture quality mode according to the facial expression information of the target passenger, automatically adjust and switch without manual operation, provide better personalized interactive experience for the target passenger, be more in line with the emotion type of the target passenger, save time and effort, be simple and convenient, and improve the satisfaction of the target passenger.

[0111] In a possible implementation, when the target vehicle screen meets the picture quality mode automatic switching condition, since there are multiple picture quality modes, in step S12, the target picture quality mode of the target vehicle screen is determined according to the emotion type of the target passenger, including:

[0112] When the target vehicle screen meets the picture quality mode automatic switching condition, if the emotion type of the target passenger is happy emotion, the target picture quality mode of the target vehicle screen is determined to be the bright mode; if the emotion type of the target passenger is anxious emotion, the target picture quality mode of the target vehicle screen is determined to be the soft mode; if the emotion type of the target passenger is fatigue emotion, the target picture quality mode of the target vehicle screen is determined to be the eye protection mode; if the emotion type of the target passenger is absent-minded emotion, the target picture quality mode of the target vehicle screen is determined to be the navigation mode; and if the emotion type of the target passenger is natural emotion, the target picture quality mode of the target vehicle screen is determined to be the standard mode.

[0113] Specifically, after obtaining the facial expression information of the target person, the AI emotion recognition software of the vehicle terminal can recognize the emotion type of the target person according to the facial expression information of the target person after being trained and optimized. The method for recognizing the emotion type is not specifically limited in this embodiment, and can be an AI emotion recognition software built according to a neural network.

[0114] As shown in Figure 3 When it is recognized that the emotion type of the target person is a happy emotion, the target picture quality mode of the target vehicle screen is determined to be a bright mode. The picture quality in the bright mode is vivid and bright, full of vitality, and can make the target person feel happier. When the target vehicle screen meets the automatic switching condition of the picture quality mode, if the current picture quality mode of the target vehicle screen is not the bright mode, the target vehicle screen is controlled to switch to the bright mode. At the same time, a linkage strategy can be used to control the multimedia device to play popular music, so that the target person feels happier.

[0115] When it is recognized that the emotion type of the target person is an anxious emotion, the target picture quality mode of the target vehicle screen is determined to be a soft mode. The picture quality in the soft mode is relatively soft in warm color, which can relieve the anxious emotion of the target person. When the target vehicle screen meets the automatic switching condition of the picture quality mode, if the current picture quality mode of the target vehicle screen is not the soft mode, the target vehicle screen is controlled to switch to the soft mode. At the same time, a linkage strategy can be used to control the aroma to be opened, and relatively soothing music to be played, so as to relieve the nervous and anxious mood of the target person and relieve the anxious emotion of the target person.

[0116] When it is recognized that the emotion type of the target person is a fatigue emotion, the target picture quality mode of the target vehicle screen is determined to be an eye protection mode. In the eye protection mode, the blue light component of the picture is lower than that in the ordinary mode, and the picture is relatively soft, which can reduce the eye irritation of the target person and make the visual experience of the target person comfortable. When the target vehicle screen meets the automatic switching condition of the picture quality mode, if the current picture quality mode of the target vehicle screen is not the eye protection mode, the target vehicle screen is controlled to switch to the eye protection mode. At the same time, a linkage strategy can be used to remind the target person to pay attention to rest, control the multimedia device to play dynamic music, and start the seat massage, so as to relieve the fatigue emotion of the target person and make the eyes of the target person rest.

[0117] When the emotion type of the target person is identified as the absent-minded emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the navigation mode. The navigation mode can remind the driver to pay attention to the road conditions in real time and timely remind the driving-related information. When the target vehicle-mounted screen meets the automatic switching condition of the picture quality mode, if the current picture quality mode of the target vehicle-mounted screen is not the navigation mode, the target vehicle-mounted screen is controlled to switch to the navigation mode. At the same time, the seat massage can also be started through the linkage strategy to stimulate the driver to adjust the attention and drive safely.

[0118] When the emotion type of the target person is identified as the natural emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the standard mode. The standard mode is the ordinary picture quality mode of the target vehicle-mounted screen, which means that no special picture processing is performed. When the target vehicle-mounted screen meets the automatic switching condition of the picture quality mode, if the current picture quality mode of the target vehicle-mounted screen is not the standard mode, the target vehicle-mounted screen is controlled to switch to the standard mode. At the same time, the interactive function can be used to quietly wait for the target person to issue an instruction, enhance the entertainment of human-computer interaction, and be more in line with the emotional status of the target person.

[0119] It can be understood that, when the target vehicle-mounted screen meets the automatic switching condition of the picture quality mode, if the emotion type of the target person is the happy emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the bright mode, if the emotion type of the target person is the anxious emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the soft mode, if the emotion type of the target person is the fatigue emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the eye protection mode, if the emotion type of the target person is the absent-minded emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the navigation mode, and if the emotion type of the target person is the natural emotion, the target picture quality mode of the target vehicle-mounted screen is determined as the standard mode. The target picture quality mode of the target vehicle-mounted screen is more in line with the emotion type of the target person. Since the emotion type is determined according to the facial expression information of the target person, the switched target picture quality mode is more in line with the current mood and emotion of the target person. The picture quality mode of the target vehicle-mounted screen does not need to be manually switched, and the visual experience of the target person is improved.

[0120] In a possible implementation, in step S13, the target vehicle-mounted screen is controlled to switch to the target picture quality mode, including:

[0121] In the case of receiving the alarm signal, in response to the alarm signal, the alarm display area of the alarm signal on the target vehicle-mounted screen is determined according to the alarm signal; the picture quality mode switching area and the non-picture quality mode switching area of the target vehicle-mounted screen are determined according to the alarm display area; the picture quality mode switching area of the target vehicle-mounted screen is controlled to switch to the target picture quality mode, and the non-picture quality mode switching area is controlled to switch to the standard mode.

[0122] Specifically, when the target vehicle-mounted screen is controlled to switch to the target image quality mode, the target person can not want to switch all regions of the target vehicle-mounted screen to the target image quality mode. For example, when the target vehicle-mounted screen is an instrument panel display screen, an alarm signal related to driving information is displayed on the instrument panel display screen, and the alarm signal is generally in a special mode such as red to remind the driver to pay attention to the alarm signal. At this time, the display region of the alarm signal does not need to switch the image quality mode according to the emotional type of the driver.

[0123] It should be noted that the vehicle-mounted terminal pre-stores the display region of each alarm signal.

[0124] In the case of receiving an alarm signal of a vehicle, the vehicle-mounted terminal displays the alarm signal on the target vehicle-mounted screen in response to the alarm signal. According to the pre-stored display region of each alarm signal and the received alarm signal, the alarm display region of the received alarm signal on the target vehicle-mounted screen is determined. According to the alarm display region, the target vehicle-mounted screen is divided into two regions, including an image quality mode switching region and a non-image quality mode switching region. The non-image quality mode switching region is the alarm display region, and the image quality mode thereof is the standard mode and does not need to be switched according to the emotional type of the target person. The image quality mode switching region is the region of the target vehicle-mounted screen other than the alarm display region, and the image quality mode thereof is automatically switched according to the emotional type of the target person.

[0125] It can be understood that when the target vehicle-mounted screen meets the image quality mode automatic switching condition, the current image quality mode of the target vehicle-mounted screen is inconsistent with the target image quality mode, and the target vehicle-mounted screen needs to be controlled to switch to the target image quality mode, if an alarm signal is received, at this time, the alarm display region of the alarm signal on the target vehicle-mounted screen can be determined in response to the alarm signal. Since the alarm display region needs to alarm and remind the target person, if the alarm display region also switches the image quality mode, it is easy to cause the target person to ignore the alarm reminder. According to the alarm display region, the image quality mode switching region and the non-image quality mode switching region of the target vehicle-mounted screen are determined, the image quality mode switching region of the target vehicle-mounted screen is controlled to switch to the target image quality mode, and the non-image quality mode switching region is controlled to switch to the standard mode, so that the alarm display region can not be switched to the target image quality mode, but to the standard mode, which can effectively remind the target person and effectively avoid the occurrence of the situation of ignoring the alarm reminder.

[0126] In a possible implementation, according to the emotional type of the target person, the target image quality mode of the target vehicle-mounted screen is determined, and before the method further includes:

[0127] According to the current image quality mode of the target vehicle-mounted screen, it is determined whether to issue a reminder notification to remind the target person whether to trigger the image quality mode automatic switching function.

[0128] In the case that the target person triggers the automatic switching function of the picture quality mode, the target vehicle-mounted screen is determined to meet the automatic switching condition of the picture quality mode in response to the triggering operation of the automatic switching function of the picture quality mode.

[0129] Specifically, the target vehicle-mounted screen can also determine whether to start the function of automatically switching the picture quality mode according to the instruction of the target person.

[0130] When the current picture quality mode of the target vehicle-mounted screen is a special picture quality mode, for example, the current picture quality mode is an eye protection mode, the eye protection mode can be a picture quality mode deliberately selected by the target person, and the target person does not need the target vehicle-mounted screen to automatically switch the picture quality mode. At this time, it is determined whether to issue a reminder notification according to the current picture quality mode of the target vehicle-mounted screen. The special picture quality mode can be set according to the needs of the target person, for example, the current picture quality mode is a navigation mode, and a reminder notification is issued. The reminder notification is used to remind the target person whether to start or trigger the automatic switching function of the picture quality mode, which can be a voice reminder or a message reminder.

[0131] The target person can issue an instruction to start the automatic switching function of the picture quality mode through gestures or voice, etc. In the case that the target person starts the automatic switching function of the picture quality mode, the target vehicle-mounted screen is determined to meet the automatic switching condition of the picture quality mode in response to the starting operation of the automatic switching function of the picture quality mode, and the target vehicle-mounted screen automatically switches the picture quality mode according to the emotional type of the target person.

[0132] When the target person issues an instruction not to start the automatic switching function of the picture quality mode, the automatic switching function of the picture quality mode is not started, and the target vehicle-mounted screen is determined not to meet the automatic switching condition of the picture quality mode in response to the operation of not starting the automatic switching function of the picture quality mode, and the target vehicle-mounted screen does not automatically switch the picture quality mode according to the emotional type of the target person.

[0133] It can be understood that it can be determined whether to issue a reminder notification according to the current picture quality mode of the target vehicle-mounted screen to remind the target person whether to trigger the automatic switching function of the picture quality mode, and the target vehicle-mounted screen is determined to meet the automatic switching condition of the picture quality mode in the case that the target person triggers the automatic switching function of the picture quality mode in response to the triggering operation of the automatic switching function of the picture quality mode, so that the automatic switching function of the picture quality mode of the target vehicle-mounted screen can be triggered according to the instruction of the user, and the interactive experience satisfaction of the target person and the visual preference matching degree of the target person are improved.

[0134] It should be understood that the size of the serial number of each step in the above embodiments does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
