Description

Technical Field

[0001] The present application relates to the field of vehicles, and more particularly, to a vehicle control method and a vehicle in the field of vehicles. Background Art

[0002] As car consumers have higher and higher requirements for visual experience, on-board display screens may be installed in multiple locations in the vehicle cabin to meet the different usage needs of the driver, co-pilot and rear passengers, and improve the convenience of obtaining information.

[0003] The operation of multiple in-vehicle display screens consumes vehicle energy. When the vehicle energy is low, continuous high-definition display on the in-vehicle display screens may cause the vehicle to run out of power and affect normal driving of the vehicle.

[0004] Therefore, how to achieve vehicle energy saving while meeting users' demand for display screens is an urgent problem to be solved. Summary of the invention

[0005] The present application provides a vehicle control method and a vehicle, which can adjust the image quality of multiple display screens while meeting user usage requirements to achieve vehicle energy saving.

[0006] In a first aspect, a vehicle control method is provided, the method comprising:

[0007] When it is detected that the vehicle has an energy-saving demand, the user position in the vehicle and the target screen in the lit state are obtained;

[0008] Based on the user position and the target screen, determine the image quality adjustment order of the target screen;

[0009] Based on the picture quality adjustment sequence, the current picture quality configuration parameters of the target screen are adjusted to the target picture quality configuration parameters, wherein the energy consumption corresponding to the target picture quality configuration parameters is less than the energy consumption corresponding to the current picture quality configuration parameters.

[0010] In the above technical solution, when it is detected that the vehicle has an energy-saving demand, the user position of the user in the vehicle is detected, and the target screen in the vehicle that is in a lit state is obtained; the image quality adjustment order of at least two target screens is determined in combination with the user position and the target screen in a lit state; and the image quality configuration parameters of the target screen are adjusted according to the image quality adjustment order. When the vehicle has an energy-saving demand, in combination with the user position and the target screen in a lit state, the screen that the user has a use demand can be determined from multiple screens in the vehicle, and then the image quality adjustment order can be determined according to the level of use demand, and the image quality of the target screen is adjusted according to the image quality adjustment order, so that the energy consumption of the adjusted target screen is less than the energy consumption of the target screen before adjustment, and the vehicle energy saving is achieved on the basis of ensuring that the adjusted target screen can meet the use needs of the user in the vehicle.

[0011] In combination with the first aspect, in some possible implementations, determining the image quality adjustment order of the target screen based on the user position and the target screen includes:

[0012] Based on the user's location, determine the target areas where the user is located;

[0013] Based on the target area, determining a first target screen in the target area among the target screens;

[0014] Based on the user position and the first target screen, a picture quality adjustment order of the first target screen is determined, wherein the picture quality adjustment order is negatively correlated with the user's usage demand for the first target screen.

[0015] In the above technical solution, first, according to the user position of the user in the car, the various target areas where the user is located are determined; according to the target area, the first target screen in each target area can be determined from the target screens in the lit state; and then combined with the user position, the image quality adjustment order of the first target screen in the target area where the user is located can be determined. For different target areas (for example, the front area, the back area, etc.), the corresponding image quality adjustment order of the screen in each area can be determined. By adjusting the image quality of the in-car screen through the image quality adjustment order, the usage requirements of users in different areas can be met, and the flexibility of adjusting the image quality of the screen can be improved. In addition, the priority in the image quality adjustment order is negatively correlated with the usage requirements, that is, the image quality of the screen with lower usage requirements is adjusted first, which can achieve the effect of energy saving of the vehicle by reducing the image quality on the basis of meeting the current usage requirements of the user.

[0016] In combination with the first aspect and the above implementation manner, in some possible implementation manners, determining the image quality adjustment order of the first target screen based on the user position and the first target screen includes:

[0017] If the user position includes the main driving position, determining that the priority of the co-pilot screen in the image quality adjustment order of the first target screen in the front area is higher than the priority of the main driving screen;

[0018] If the user position does not include the main driving position, detect whether the user position includes the co-pilot position to obtain a first detection result; based on the first detection result, determine the image quality adjustment order of the first target screen in the front row area.

[0019] In the above technical solution, during the driving of the vehicle, the main driver has a greater demand for the use of the main driver screen; when there is a main driver in the vehicle, the priority of the co-driver screen is determined to be higher than that of the main driver screen; the use needs of the main driver can be met first, avoiding reducing the image quality of the main driver screen and affecting the main driver's acquisition of information. When there is no main driver in the car, it is further detected whether the co-driver is included, and the image quality adjustment order in the front area is determined based on the detection results. The screens in the front area mainly include the main driver screen and the co-driver screen. When there is no main driver, the image quality adjustment order is determined based on the use of the co-driver screen, so that the image quality adjustment can meet the actual user needs and further improve the flexibility of multi-screen image quality adjustment.

[0022] If the first detection result indicates that the user position does not include the co-pilot position, detect whether there is a user in the back row to obtain a second detection result; based on the second detection result, determine the image quality adjustment order of the first target screen in the front row area.

[0023] In the above technical solution, when there is no main driver user in the vehicle but there is a co-driver user, the priority of the main driver screen is determined to be higher than that of the co-driver screen, that is, the picture quality of the main driver screen is adjusted first to meet the co-driver user's demand for using the co-driver screen; when there is no co-driver user, it is further detected whether there is a back-seat user to determine whether there is a user in the vehicle who needs to use the screen, and the order of picture quality adjustment is determined based on the detection result. On the basis of ensuring the usage needs, the screen picture quality is adjusted to improve the flexibility of picture quality adjustment.

[0024] In combination with the first aspect and the above implementation manner, in some possible implementation manners, determining the image quality adjustment order of the first target screen in the front row area based on the second detection result includes:

[0025] If the second detection result indicates that there is a rear-seat user, determining that the priority of the main driving screen is higher than the priority of the co-pilot screen in the image quality adjustment sequence of the first target screen in the front-row area;

[0026] The method further includes:

[0027] If the second detection result indicates that there is no rear seat user, the front passenger screen is turned off.

[0028] In the above technical solution, when it is detected that there are rear-seat users in the car, the rear-seat users may have the need to obtain information through the co-pilot screen, and the priority of the main driving screen is determined to be higher than that of the co-pilot screen to meet the viewing needs of the users in the car; when there are no rear-seat users, the co-pilot screen is directly turned off to avoid unnecessary lighting of the screen, causing energy waste, and further meeting the energy-saving needs of the vehicle.

[0029] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0030] If the co-pilot screen includes a first co-pilot screen and a second co-pilot screen, obtaining a visual area of ​​the co-pilot user, wherein the first co-pilot screen and the second co-pilot screen are located at different positions in front of the co-pilot position;

[0031] If the sight area is located on the first co-pilot screen, determining that the second co-pilot screen has a higher priority than the first co-pilot screen in the image quality adjustment sequence of the co-pilot screen;

[0032] If the sight area is located on the second co-pilot screen, it is determined that the priority of the first co-pilot screen in the image quality adjustment order of the co-pilot screen is higher than the priority of the second co-pilot screen.

[0033] In the above technical solution, when the co-pilot screen includes two screens, the line of sight area of ​​the co-pilot user is obtained; the order of picture quality adjustment is determined according to the screen where the line of sight area is located; the screen where the line of sight area is located is determined as a screen with lower priority, and the picture quality of the screen with lower usage demand is adjusted first. While meeting the current usage needs of the co-pilot user, the picture quality of the other screen is appropriately reduced to achieve vehicle energy saving.

[0034] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0037] If the user type indicates that there is a target user of a preset type, based on the user position of the target user, it is determined that the priority of the first rear row screen in the image quality adjustment order of the first target screen in the rear row area is higher than the priority of the second rear row screen, wherein the distance between the second rear row screen and the target user is smaller than the distance between the first rear row screen and the target user.

[0038] In the above technical solution, when it is detected that there are rear-seat users in the car, the user type of the rear-seat user is obtained; if there is a preset type of target user among the rear-seat users, the image quality adjustment order of the first target screen in the rear-seat area is determined according to the user position of the target user; it is determined that the priority of the screen farther from the target user is higher than the priority of the screen closer to the target user. The preset types can be children and the elderly, etc. Based on the user type of the user, the priority of the image quality adjustment order is determined, which can ensure the needs of the preset type of users to view the screen content, avoid reducing the image quality to affect the target user's viewing of the screen content, and provide users with a better visual experience.

[0039] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0040] If there is no target user in the rear area, obtain the number of first users in the first sub-area and the number of second users in the second sub-area;

[0041] Based on the first number of users and the second number of users, it is determined that the priority of the first rear screen in the image quality adjustment order of the first target screen in the rear area is higher than the priority of the second rear screen, wherein the number of users in the sub-area corresponding to the second rear screen is less than the number of users in the sub-area corresponding to the first rear screen.

[0042] In the above technical solution, when it is detected that there is no target user of the preset type in the rear area, the number of users in each sub-area of ​​the rear area is obtained, and the priority of the rear screen corresponding to the area with a smaller number of users is determined to be higher than the priority of the rear screen corresponding to the area with a larger number of users. When the user's seat is close to one side, there may be a demand for the screen on one side only. The screen quality on the other side is adjusted first, which can reduce the impact on the screen with a larger current demand, and achieve vehicle energy saving on the basis of meeting the actual use needs of users.

[0043] In combination with the first aspect and the above implementations, in some possible implementations, based on the image quality adjustment order, adjusting the current image quality configuration parameters of the target screen to the target image quality configuration parameters includes:

[0045] When the real-time power reaches the power threshold, the current image quality configuration parameters of the second screen are adjusted to the target image quality configuration parameters, wherein the priority of the first screen in the image quality adjustment sequence is higher than the priority of the second screen.

[0046] In the above technical solution, after determining the picture quality adjustment order, the picture quality of the first screen with a higher priority is adjusted first; in the process of adjusting the picture quality of the first screen according to the picture quality adjustment order, the real-time power of the vehicle is obtained, and when the real-time power drops to the power threshold, the picture quality of the second screen with a lower priority is adjusted. In combination with the real-time power, it is determined whether to adjust the picture quality of the screen, which improves the flexibility of multi-screen picture quality adjustment, which can not only meet the energy-saving needs of the vehicle, but also reduce the impact on the user's use of the screen.

[0061] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text 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 the description of the embodiments of the present application, "multiple" means two or more than two.

[0062] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0063] The in-vehicle display is an important interactive interface in modern cars, used to display navigation, entertainment, vehicle information and other functions. With the development of technology, the functions and performance of in-vehicle displays are constantly improving, becoming a key component to enhance driving experience and safety.

[0064] In recent years, with the rapid development of automobile technology and consumers' increasing attention to driving experience, it has become popular to install multiple display screens in car cockpits. The multi-screen configuration not only makes the car more entertaining and intelligent, but also greatly improves the user's driving experience and comfort.

[0065] The following will be combined Figure 1 and Figure 2 Introducing the in-vehicle display screens that may be configured in the vehicle cockpit.

[0066] Figure 1 It is a schematic diagram of a scenario provided in an embodiment of the present application. Figure 1The indicative is a vehicle display screen that may be configured in the front row area of ​​the vehicle, the front row area is the first row of the vehicle cabin, that is, the area where the main driver and the co-driver are located. The vehicle display screen in the front row area may include an instrument screen 101, a central control screen 102, a co-driver entertainment screen 103, and a co-driver ceiling screen 104.

[0067] The instrument panel 101 is usually installed on the center console in front of the main driver's seat, and is used to display various key information of the vehicle, such as speed, rotation speed, fuel level, battery power, temperature, etc.

[0068] The central control screen 102 is usually installed in the center of the vehicle's center console, and is used to display navigation information, entertainment information, vehicle status (such as fuel level, battery power, tire pressure, etc.), and is used to adjust various vehicle settings (such as air conditioning, seat heating, driving mode, etc.) and realize interconnection functions.

[0069] The co-pilot entertainment screen 103 is usually installed on the center console in front of the co-pilot seat to meet the entertainment and information acquisition needs of the co-pilot user.

[0070] The co-pilot ceiling screen 104 is usually installed on the top of the vehicle in front of the co-pilot seat to meet the entertainment and information acquisition needs of users such as the co-pilot user or the rear seat users.

[0071] Figure 2 This is another scenario schematic diagram provided in an embodiment of the present application. Figure 2 Indicated in the figure are the in-vehicle display screens that may be configured in the rear area of ​​the vehicle, which is the area other than the front area where the main driver and the co-driver are located. For example, the rear area may be the second row area, the third row area, etc. The in-vehicle display screens in the rear area may include a left display screen 201 and a right display screen 202, etc.

[0072] The left display screen 201 is usually installed on the backrest of the main driver's seat or on the top of the vehicle on the left side of the rear area, facing the rear users to meet the entertainment and information acquisition needs of the rear users.

[0073] The right display screen 202 is usually installed on the backrest of the front passenger seat or on the top of the vehicle on the right side of the rear area, facing the rear users to meet the entertainment and information acquisition needs of the rear users.

[0074] It should be noted that the specific area division and the configuration of the vehicle-mounted display screen need to be determined according to the actual vehicle model. The embodiment of the present application does not limit the area division within the vehicle, the number of vehicle-mounted display screens installed, and the installation location. It should be understood that the vehicle can include at least two of the above screens.

[0075] In order to improve user experience and ensure driving safety, in-vehicle displays are usually configured with better picture quality parameters, such as high resolution, high brightness or high contrast. Each in-vehicle display generates power consumption during operation. When multiple in-vehicle displays in the vehicle cabin operate at a higher picture quality at the same time, the power consumption generated will be greater. For electric vehicles or hybrid vehicles, the larger display power consumption may cause the vehicle's battery to decrease at a faster rate, and may even cause the vehicle to lose power, affecting the normal driving of the vehicle.

[0076] In view of the above problems, the present application provides a vehicle control method and a vehicle. When it is detected that the vehicle has an energy-saving demand, the image quality adjustment order of the target screen in the lit state is determined according to the user position in the vehicle. Afterwards, according to the image quality adjustment order, the current image quality configuration parameters of the target screen are adjusted to the target image quality configuration parameters to reduce the energy consumption generated by the target screen. On the basis of meeting the user's use requirements for the screen, the image quality configuration parameters of the screen are adjusted to meet the energy-saving requirements of the vehicle.

[0077] Combine the following Figures 3 to 5 The vehicle control method provided in the embodiment of the present application is described in detail.

[0078] Figure 3 is a schematic flow chart of a vehicle control method provided by an embodiment of the present application. It should be understood that the method can be applied to a vehicle; or, applied to a processor in a vehicle; or, applied to a chip in a processor mounted in a vehicle.

[0079] For example, Figure 3 As shown, the method 300 includes the following steps S301-S303.

[0080] S301, when it is detected that the vehicle has an energy-saving demand, obtain the user position in the vehicle and the target screen in the lit state.

[0081] For example, during the operation of the vehicle, the energy consumption indicators of the vehicle are monitored in real time, such as the battery power (for electric vehicles), the remaining fuel (for fuel vehicles), and the real-time energy consumption of the engine or motor, to determine whether the vehicle needs to save energy. If it is determined that the vehicle needs to save energy, the user position of the user in the vehicle cabin and the target screen in the lit state are further obtained.

[0082] Optionally, as to the method of detecting whether the vehicle has an energy-saving demand, data from an energy monitoring system may be obtained and a corresponding energy threshold may be set. When the energy consumption index meets the threshold condition, it is determined that the vehicle has an energy-saving demand.

[0083] For example, the battery power of the vehicle is monitored, and a power threshold is set to 40%. If it is detected that the current battery power of the vehicle is less than or equal to the power threshold of 40%, it is determined that the vehicle has an energy saving demand. On the contrary, if it is detected that the current battery power of the vehicle is greater than the power threshold of 40%, it is determined that the vehicle does not have an energy saving demand.

[0084] It should be understood that the setting of the energy threshold needs to be combined with the actual vehicle performance, etc. The above values ​​are only used as examples, and this application does not make any specific limitations on the setting values ​​of the energy threshold.

[0085] Optionally, when it is detected that the vehicle does not have energy-saving requirements, the display mode of the vehicle display screen can be set to the standard mode. In the standard mode, the vehicle display screen can display with the default image quality configuration parameters, or display according to the user-defined image quality configuration parameters. When it is detected that the vehicle has energy-saving requirements, the display mode of the vehicle display screen can be automatically controlled to switch to the intelligent tuning mode to meet the vehicle's energy-saving requirements.

[0086] Optionally, with regard to the method of obtaining the user's position in the vehicle, the user's position in the vehicle can be determined by obtaining data from vehicle-mounted sensors; or obtaining a cabin image through a vehicle-mounted camera to determine the user's position; or detecting the signal strength of electronic equipment in the vehicle to determine the user's position, etc.

[0087] For example, an infrared sensor, an ultrasonic sensor or a pressure sensor may be installed in the vehicle cabin, and the position of the user in the vehicle may be determined by receiving monitoring data from the sensor.

[0088] Exemplarily, an in-vehicle camera may be installed in the vehicle cabin for capturing images of the vehicle cabin. An image recognition algorithm may be used to determine the location of the user in the vehicle based on the cabin image.

[0089] For example, if a user's mobile device (eg, cell phone, tablet) is connected to the vehicle system via Bluetooth or Wi-Fi, the vehicle can estimate the user's location using the strength of these wireless signals.

[0090] Optionally, in order to improve the accuracy of the user's position, two or more methods may be used to determine the user's position in the vehicle. The embodiments of the present application do not limit the specific acquisition methods and the number of methods.

[0091] Optionally, for the on-board display screens configured in the vehicle, some on-board display screens are turned on by default after the vehicle is powered on, and some on-board display screens can be turned on manually; the vehicle system can determine whether the screen is in a lit state based on the operation identifier of each on-board display screen.

[0092] It should be noted that for a screen that is in the off state, since it is not in working state, the energy consumption generated is low or no energy consumption, so its picture quality configuration parameters will not be adjusted.

[0093] S302: Determine the image quality adjustment order of the target screen based on the user position and the target screen.

[0094] For example, users at different locations use different in-vehicle display screens, and different in-vehicle display screens have different importance in vehicle operation and safety during vehicle driving. After determining the user position of the user in the vehicle and the target screen in the lit state, the image quality adjustment order of the target screen can be determined according to the user position, that is, the priority ranking between the various screens during the image quality adjustment process.

[0095] Optionally, in the process of determining the image quality adjustment sequence of the target screens, the corresponding image quality adjustment sequence may be determined according to the demand levels between the target screens.

[0096] For example, during vehicle driving, the driver needs to obtain basic driving information of the vehicle through the instrument screen and view navigation information through the central control screen. Compared with other entertainment screens, the main driving screen is more important. Therefore, the image quality adjustment order can be determined as follows: the priority of other screens (such as the co-pilot screen, the rear screen, etc.) is higher than the priority of the main driving screen (such as the instrument screen, the central control screen, etc.).

[0097] If the image quality adjustment order is determined only based on the importance of the target screens, the image quality adjustment may not meet the actual usage needs of users in different areas of the car. Therefore, the corresponding image quality adjustment order can be determined for each different area. In one implementation, the image quality adjustment order of the target screen is determined based on the user position and the target screen, including:

[0098] Based on the user's location, determine the target areas where the user is located;

[0099] Based on the target area, determining a first target screen in the target area among the target screens;

[0100] Based on the user position and the first target screen, a picture quality adjustment order of the first target screen is determined, wherein the picture quality adjustment order is negatively correlated with the user's usage demand for the first target screen.

[0101] Exemplarily, taking a 2-row 5-seat vehicle as an example, the passenger positions in the vehicle may include the main driving position, the co-pilot position, the left rear position, the middle rear position, and the right rear position. If the user position includes the main driving position and / or the co-pilot position, the target area can be determined to be the front row area. If the user position includes the left rear position and / or the middle rear position and / or the right rear position, the target area can be determined to be the rear row area. After determining the target area corresponding to the user position, the first target screen that is lit in the area can be further determined. Afterwards, the image quality adjustment order of the first target screen in each target area can be determined based on the user position and the first target screen.

[0102] For screens with lower usage requirements, they can be adjusted first; for screens with higher usage requirements, in order to avoid affecting the normal use of users, the screens with lower usage requirements can be adjusted first, and then the screens with higher usage requirements. That is, the order of image quality adjustment is negatively correlated with the user's usage requirements for the first target screen.

[0103] For example, see Figure 1 and Figure 2 If the target area determined according to the user's position is the front row area, the corresponding first target screen may include: Figure 1 The instrument screen 101, the central control screen 102, the co-pilot entertainment screen 103 and the co-pilot ceiling screen 104 are shown. If the target area determined according to the user's position is the rear area, the corresponding first target screen may include the following: Figure 2 The left display screen 201 and the right display screen 202 are shown.

[0104] It should be understood that in this application, the expression "sequence" refers to the order in which the image quality of the target screen is adjusted. When there is only one target screen, only the image quality of the target screen can be adjusted. In this case, "sequence" means adjusting the image quality of the target screen, and not adjusting the image quality of other screens, because the other screens are not lit. When there are multiple target screens, the image quality of the multiple target screens can all be adjusted. In this case, "sequence" means the order in which the image quality of the multiple target screens is adjusted.

[0105] In an embodiment of the present application, first, according to the user position of the user in the car, the target areas where the user is located are determined; according to the target area, the first target screen in each target area can be determined from the target screens in the lit state; and then combined with the user position, the image quality adjustment order of the first target screen in the target area where the user is located can be determined. For different target areas (for example, the front area, the back area, etc.), the corresponding image quality adjustment order of the screen in each area can be determined. By adjusting the image quality of the in-car screen through the image quality adjustment order, the usage requirements of users in different areas can be met, and the flexibility of adjusting the image quality of the screen can be improved. In addition, the priority in the image quality adjustment order is negatively correlated with the usage requirements, that is, the image quality of the screen with lower usage requirements is adjusted first, which can achieve the effect of energy saving of the vehicle by reducing the image quality on the basis of meeting the current usage requirements of the user.

[0106] In one implementation, determining the image quality adjustment order of the first target screen based on the user position and the first target screen includes:

[0107] If the user position includes the main driving position, determining that the priority of the co-pilot screen in the image quality adjustment order of the first target screen in the front area is higher than the priority of the main driving screen;

[0108] If the user position does not include the main driving position, detect whether the user position includes the co-pilot position to obtain a first detection result; based on the first detection result, determine the image quality adjustment order of the first target screen in the front row area.

[0109] The main driving screen is used to indicate the screens with high usage requirements of the driver, which may include an instrument screen and / or a central control screen, etc. The co-pilot screen is used to indicate the screens with high usage requirements of the co-pilot user, which may include one or more display screens.

[0110] For example, for the front row area of ​​the vehicle cockpit, if the user position includes the main driving position, the driver needs to obtain vehicle-related information through the main driving screen, and compared with the co-pilot screen, the image quality display of the main driving screen may affect driving safety. Therefore, it is determined that the priority of the co-pilot screen in the image quality adjustment sequence is higher than that of the main driving screen, that is, the image quality configuration parameters of the co-pilot screen are adjusted first, and then the image quality configuration parameters of the main driving screen are adjusted. When the main driving position is not included in the user position, it indicates that the user in the car has a low demand for the use of the main driving screen, and then it can be further detected whether the user position includes the co-pilot position, that is, it can be detected whether there is a co-pilot user, so as to determine the image quality adjustment sequence of the screen in the front row area.

[0111] Optionally, when the user position includes the main driver's position, in order to avoid affecting the main driver's user's reading of vehicle information and driving safety, the picture quality adjustment of the main driver's screen can be prohibited, that is, only the picture quality adjustment order of display screens other than the main driver's screen is determined, and the picture quality of other display screens is adjusted according to the picture quality adjustment order.

[0112] In the embodiment of the present application, during the driving of the vehicle, the main driver has a greater demand for the use of the main driver screen; when there is a main driver in the vehicle, the priority of the co-driver screen is determined to be higher than that of the main driver screen; the use needs of the main driver can be met first, avoiding the reduction of the image quality of the main driver screen and affecting the main driver's acquisition of information. When there is no main driver in the vehicle, it is further detected whether the co-driver is included, and the image quality adjustment order in the front area is determined based on the detection results. The screens in the front area mainly include the main driver screen and the co-driver screen. When there is no main driver, the image quality adjustment order is determined based on the use of the co-driver screen, so that the image quality adjustment can meet the actual user needs and further improve the flexibility of multi-screen image quality adjustment.

[0113] In one implementation, based on the first detection result, determining the image quality adjustment order of the first target screen in the front row area includes:

[0114] If the first detection result indicates that the user position includes the co-pilot position, determining that the priority of the main driving screen is higher than the priority of the co-pilot screen in the image quality adjustment sequence of the first target screen in the front row area;

[0115] If the first detection result indicates that the user position does not include the co-pilot position, detect whether there is a user in the back row to obtain a second detection result; based on the second detection result, determine the image quality adjustment order of the first target screen in the front row area.

[0116] For example, when the user position does not include the main driving position but includes the co-pilot position, it is necessary not only to meet the co-pilot user's need to watch audio and video, but also to give priority to ensuring the best effect of the co-pilot user's current viewing screen, then determine that the priority of the main driving screen in the image quality adjustment order is higher than the priority of the co-pilot screen, that is, the image quality configuration parameters of the main driving screen are adjusted first, and then the image quality configuration parameters of the co-pilot screen are adjusted. When the user position does not include the main driving position and the co-pilot position, the rear-seat user may view information through the front-seat screen. In order to further determine the image quality adjustment order, it is possible to detect whether there is a rear-seat user, and determine the image quality adjustment order of the screen in the front row area based on the detection result.

[0117] Optionally, for the method of detecting whether there is a user in the back row, reference may be made to the method of determining the user position in the above S301, for example, using a sensor, image recognition, etc., which will not be elaborated in detail in the embodiment of the present application.

[0118] In an embodiment of the present application, when there is no main driver user in the vehicle but there is a co-driver user, the priority of the main driver screen is determined to be higher than that of the co-driver screen, that is, the picture quality of the main driver screen is adjusted preferentially to meet the co-driver user's demand for using the co-driver screen; when there is no co-driver user, it is further detected whether there is a back-seat user to determine whether there is a user in the vehicle who needs to use the screen, and the order of picture quality adjustment is determined based on the detection result. On the basis of ensuring the usage demand, the screen picture quality is adjusted to improve the flexibility of picture quality adjustment.

[0119] In one implementation, based on the second detection result, determining the image quality adjustment order of the first target screen in the front row area includes:

[0120] If the second detection result indicates that there is a rear-seat user, determining that the priority of the main driving screen is higher than the priority of the co-pilot screen in the image quality adjustment sequence of the first target screen in the front-row area;

[0121] The method further includes:

[0122] If the second detection result indicates that there is no rear seat user, the front passenger screen is turned off.

[0123] For example, when it is detected that there is a rear-seat user in the vehicle, the rear-seat user may use the co-pilot screen in the front area to watch movies or listen to music from a distance, so the priority of the main driver screen in the image quality adjustment sequence is determined to be higher than that of the co-pilot screen. When it is detected that there is no rear-seat user in the vehicle, there is no user in the vehicle at this time, and the co-pilot screen can be directly controlled to be turned off.

[0124] Optionally, when multiple co-pilot screens are installed at the co-pilot position, the priorities of the multiple co-pilot screens can be determined to be at the same level, and the multiple co-pilot screens can be adjusted synchronously.

[0125] Optionally, since the main driver's screen is a constantly on screen for users to view key information, in order to ensure that users can view key information and achieve energy saving, the image quality of the main driver's screen can be adjusted after turning off the co-pilot screen.

[0126] In an embodiment of the present application, when it is detected that there are rear-seat users in the vehicle, the rear-seat users may have a need to obtain information through the co-pilot screen, and the priority of the main driver's screen is determined to be higher than that of the co-pilot screen to meet the viewing needs of the users in the vehicle; when there are no rear-seat users, the co-pilot screen is directly turned off to avoid unnecessary lighting of the screen, which causes energy waste and further meets the energy-saving needs of the vehicle.

[0127] In one implementation, if the co-pilot screen includes a first co-pilot screen and a second co-pilot screen, obtaining a visual area of ​​the co-pilot user, wherein the first co-pilot screen and the second co-pilot screen are located at different positions in front of the co-pilot position;

[0128] If the sight area is located on the first co-pilot screen, determining that the second co-pilot screen has a higher priority than the first co-pilot screen in the image quality adjustment sequence of the co-pilot screen;

[0129] If the sight area is located on the second co-pilot screen, it is determined that the priority of the first co-pilot screen in the image quality adjustment order of the co-pilot screen is higher than the priority of the second co-pilot screen.

[0130] For example, for some models, two co-pilot screens may be installed at the co-pilot position to enable the co-pilot user to easily obtain information in different postures. When the vehicle contains multiple co-pilot screens, the co-pilot user's line of sight area can be further obtained, and the image quality adjustment order can be determined according to the co-pilot user's line of sight area; when the line of sight area is located on one of the co-pilot screens, it indicates that the co-pilot user has a higher demand for the use of the current co-pilot screen, and it can be determined that the priority of another co-pilot screen in the image quality adjustment order is higher than the current co-pilot screen, that is, the image quality configuration parameters of the unused co-pilot screen are adjusted first.

[0131] Exemplarily, when the co-pilot screen includes Figure 1 As shown in the co-pilot entertainment screen 103 and the co-pilot ceiling screen 104, if the co-pilot user's line of sight is located on the co-pilot entertainment screen 103, the picture quality configuration parameters of the co-pilot ceiling screen 104 are adjusted first; if the co-pilot user's line of sight is located on the co-pilot ceiling screen 104, the picture quality configuration parameters of the co-pilot entertainment screen 103 are adjusted first.

[0132] Alternatively, the head posture of the co-pilot user can be obtained through a camera installed in the car, and the position, tilt angle, and rotation angle of the head can be identified through a computer vision algorithm to determine the co-pilot user's line of sight area. Alternatively, a dedicated eye tracking device, such as an eye tracker based on the principle of infrared light reflection, can be used to track the movement of the user's eyes with high precision to determine the exact point of sight.

[0133] Optionally, when the co-pilot screen includes multiple screens, the seat position of the co-pilot seat can be monitored, and the co-pilot screen that the co-pilot user may currently be using can be determined based on the seat position or the inclination angle of the seat back, and the order of picture quality adjustment of the multiple co-pilot screens can be further determined.

[0134] For example, when the seat back is tilted at a small angle, it is more convenient to use the co-pilot entertainment screen in front of the seat for entertainment activities, so it can be determined that the priority of the co-pilot ceiling screen is higher than the priority of the co-pilot entertainment screen. When the seat back is tilted at a large angle, the user may be in a semi-reclining or lying position. At this time, it is more convenient to use the co-pilot ceiling screen above the front side of the seat for entertainment activities, so it can be determined that the priority of the co-pilot entertainment screen is higher than the priority of the co-pilot ceiling screen.

[0135] It should be noted that in the embodiment of the present application, only the co-pilot screen includes two screens as an example. When more display screens are installed in the co-pilot area, the solution in the embodiment of the present application can still be adopted. By detecting the line of sight area of ​​the co-pilot user, the picture quality adjustment order of multiple screens is determined. The embodiment of the present application does not limit the number of screens installed.

[0136] In an embodiment of the present application, when the co-pilot screen includes two screens, the line of sight area of ​​the co-pilot user is obtained; the order of picture quality adjustment is determined according to the screen where the line of sight area is located; the screen where the line of sight area is located is determined as a screen with lower priority, and the picture quality of the screen with lower usage demand is adjusted preferentially. While meeting the current usage demand of the co-pilot user, the picture quality of the other screen is appropriately reduced to achieve vehicle energy saving.

[0137] The display screen installed in the rear area of ​​the vehicle cabin is used to meet the needs of rear users. Usually, the elderly, children and other users will sit in the rear area. In order to avoid the low-quality display affecting the eyesight of children or affecting the normal viewing of the display content by the elderly, the corresponding image quality adjustment order can be determined according to the user type of the rear user. In one implementation, if the presence of a rear user is detected, the user type of the rear user is obtained;

[0138] Based on the user position and the first target screen, determining the image quality adjustment order of the first target screen includes:

[0139] If the user type indicates that there is a target user of a preset type, based on the user position of the target user, it is determined that the priority of the first rear row screen in the image quality adjustment order of the first target screen in the rear row area is higher than the priority of the second rear row screen, wherein the distance between the second rear row screen and the target user is smaller than the distance between the first rear row screen and the target user.

[0140] Among them, the preset types can be user types such as the elderly and children who have higher image quality display requirements.

[0141] Exemplarily, when a rear-seat user is detected in the rear-seat area of ​​the vehicle, the user type of the rear-seat user is determined. If a target user of a preset type is detected among the rear-seat users, the image quality adjustment order of the screens in the rear-seat area is determined according to the user position of the target user. The image quality adjustment order is determined such that the priority of the rear-seat screens farther from the target user is higher than the priority of the rear-seat screens closer to the target user.

[0142] For example, when it is detected that a child is sitting in the rear area and the child's user position is determined to be the left side of the rear row, the order of image quality adjustment of the rear screen can be determined as follows: the priority of the right side of the rear screen is higher than the priority of the left side of the rear screen, that is, the image quality configuration parameters of the right side of the screen are adjusted first; if there is a child sitting on the left side of the rear area and an elderly person sitting on the right side, it can be determined that the priorities of the screens on both sides are the same, and the image quality configuration parameters of the two screens can be adjusted synchronously, or the image quality configuration parameters of the two screens can be not adjusted.

[0143] In the embodiment of the present application, when it is detected that there are rear-seat users in the vehicle, the user type of the rear-seat user is obtained; if there is a preset type of target user among the rear-seat users, the image quality adjustment order of the first target screen in the rear-seat area is determined according to the user position of the target user; it is determined that the priority of the screen farther from the target user is higher than the priority of the screen closer to the target user. The preset types can be children and the elderly, etc. Based on the user type of the user, the priority of the image quality adjustment order is determined, which can ensure the needs of the preset type of user to view the screen content, avoid reducing the image quality to affect the target user's viewing of the screen content, and provide users with a better visual experience.

[0144] In one implementation, if there is no target user in the rear area, the number of first users in the first sub-area and the number of second users in the second sub-area are obtained;

[0145] Based on the first number of users and the second number of users, it is determined that the priority of the first rear screen in the image quality adjustment order of the first target screen in the rear area is higher than the priority of the second rear screen, wherein the number of users in the sub-area corresponding to the second rear screen is less than the number of users in the sub-area corresponding to the first rear screen.

[0146] Exemplarily, when it is detected that there is no target user of a preset type in the rear area, the image quality adjustment order of the rear screens is determined according to the number of users in the two sub-areas in the rear area. The image quality adjustment order is determined such that the priority of the screen in the area with more users is higher than the priority of the screen in the area with less users.

[0147] For example, if there are three users in the rear area, the distance between the middle user's seat and the two sides of the vehicle can be determined; if the middle user is biased to the left, the number of users in the rear left area can be determined to be 2, and the number of users in the rear right area can be determined to be 1, and the image quality adjustment order of the rear screens can be determined accordingly, with the priority of the right display screen being higher than the priority of the left display screen. If the user in the middle position of the rear row sits in the center of the rear area, the priority of the display screens on both sides can be determined to be the same, and the image quality configuration parameters of the two display screens can be adjusted synchronously.

[0148] Optionally, when there are multiple display screens in the rear area, the display screen currently being used by the rear user is determined in combination with the sight area of ​​the rear user, and the priority of the unused display screen is determined to be higher than the priority of the display screen being used.

[0149] In the embodiment of the present application, when it is detected that there is no target user of a preset type in the rear area, the number of users in each sub-area of ​​the rear area is obtained, and the priority of the rear screen corresponding to the area with a smaller number of users is determined to be higher than the priority of the rear screen corresponding to the area with a larger number of users. When the user's seat is close to one side, there may be a demand for the screen on one side only. The image quality of the screen on the other side is adjusted first, which can reduce the impact on the screen with a larger current demand, and achieve vehicle energy saving on the basis of meeting the actual use needs of the user.

[0150] S303, based on the image quality adjustment sequence, adjusting the current image quality configuration parameters of the target screen to target image quality configuration parameters, wherein the energy consumption corresponding to the target image quality configuration parameters is less than the energy consumption corresponding to the current image quality configuration parameters.

[0151] The image quality configuration parameters may include screen resolution, display brightness, display contrast and other parameters.

[0152] For example, after determining the image quality adjustment sequence of the target screen according to the user position of the user in the vehicle and the target screen in the lit state, the current image quality configuration parameters of the target screen can be adjusted to the target image quality configuration parameters in sequence according to the image quality adjustment sequence. In order to meet the energy-saving requirements of the vehicle, the image quality configuration parameters are adjusted downward, that is, the energy consumption generated by the target screen displaying with the target image quality configuration parameters is less than the energy consumption generated by the target screen displaying with the current image quality configuration parameters.

[0153] It should be noted that, in order to ensure the normal use requirements of the target screen by the user, the target image quality configuration parameters need to meet the standard that the user can clearly view the display content on the target screen.

[0154] Exemplarily, after the image quality adjustment sequence in each target area is determined, the image quality of the first target screen in the target area is adjusted according to the image quality adjustment sequence corresponding to each target area.

[0155] In one implementation, based on the picture quality adjustment sequence, the current picture quality configuration parameters of the first screen are adjusted to the target picture quality configuration parameters, and the real-time power of the vehicle is obtained;

[0156] When the real-time power reaches the power threshold, the current image quality configuration parameters of the second screen are adjusted to the target image quality configuration parameters, wherein the priority of the first screen in the image quality adjustment sequence is higher than the priority of the second screen.

[0157] For example, the image quality adjustment of multiple target screens is used to achieve vehicle energy saving. After determining the image quality adjustment order, the image quality of the first screen with a higher priority in the image quality adjustment order can be adjusted first. After that, the real-time power of the vehicle is monitored. When the real-time power reaches a preset power threshold, the image quality of the second screen after the first screen is adjusted.

[0158] Exemplarily, when the battery level of the vehicle reaches 40%, it can be determined that the vehicle has an energy-saving demand. At this time, according to the user position and the target screen, the image quality adjustment order of the target screen is determined to be that the priority of the first screen is higher than the priority of the second screen. After determining the image quality adjustment order, first adjust the current image quality configuration parameters of the first screen to the target image quality configuration parameters. After adjusting the image quality of the first screen, continuously monitor the real-time battery level of the vehicle, and when the real-time battery level reaches 30%, adjust the image quality of the second screen.

[0159] It should be noted that the embodiment of the present application only takes the two-priority picture quality configuration order as an illustration. When the picture quality adjustment order indicates the priority order between multiple target screens, multi-level power thresholds can be set. Combined with the multi-level power thresholds and picture quality adjustment order, the picture quality of multiple target screens can be adjusted in turn.

[0160] For example, when the image quality adjustment order indicates that the priority of the first screen is higher than the priority of the second screen, and the priority of the second screen is higher than the priority of the third screen, it can be determined that the first power threshold is 30% and the second power threshold is 20%. First, the image quality of the first screen is adjusted, and when the real-time power of the vehicle is reduced to 30%, the image quality of the second screen is adjusted. When the real-time power is reduced to 20%, the image quality of the second screen is adjusted.

[0161] It should be noted that the above threshold settings are only used as examples. In actual application, the corresponding thresholds need to be determined in combination with factors such as the actual vehicle operating conditions and vehicle model.

[0162] Optionally, different target screens may have different physical configuration parameters. During the image quality adjustment process, the target image quality configuration parameters corresponding to each target screen may be determined, and the current screen may be adjusted according to the target image quality configuration parameters corresponding to the current screen.

[0163] In the embodiment of the present application, after determining the image quality adjustment order, the image quality of the first screen with a higher priority is adjusted first; in the process of adjusting the image quality of the first screen according to the image quality adjustment order, the real-time power of the vehicle is obtained, and when the real-time power drops to the power threshold, the image quality of the second screen with a lower priority is adjusted. In combination with the real-time power, it is determined whether to adjust the image quality of the screen, which improves the flexibility of multi-screen image quality adjustment, which can not only meet the energy-saving needs of the vehicle, but also reduce the impact on the user's use of the screen.

[0164] In summary, in the embodiment of the present application, when it is detected that the vehicle has an energy-saving demand, the user position of the user in the vehicle is detected, and the target screen in the vehicle that is in a lit state is obtained; the image quality adjustment order of at least two target screens is determined in combination with the user position and the target screen in a lit state; and the image quality configuration parameters of the target screen are adjusted according to the image quality adjustment order. When the vehicle has an energy-saving demand, in combination with the user position and the target screen in a lit state, the screen that the user has a use demand can be determined from multiple screens in the vehicle, and then the image quality adjustment order can be determined according to the level of use demand, and the image quality of the target screen is adjusted according to the image quality adjustment order, so that the energy consumption of the adjusted target screen is less than the energy consumption of the target screen before adjustment, and the vehicle energy saving is achieved on the basis of ensuring that the adjusted target screen can meet the use needs of the user in the vehicle.

[0165] Figure 4 is a schematic flow chart of another vehicle control method provided by an embodiment of the present application. It should be understood that the method can be applied to a vehicle; or, applied to a processor in a vehicle; or, applied to a chip in a processor mounted in a vehicle.

[0166] For example, Figure 4 As shown, the method 400 includes the following steps S401-S411.

[0167] S401, when it is detected that the vehicle has an energy-saving demand, the user position in the front area of ​​the vehicle cabin and the target screen in the lit state are obtained.

[0175] Exemplarily, when it is detected that the user position includes the main driving position, it is determined that the adjustment priority of the co-pilot screen is higher than the adjustment priority of the main driving screen.

[0176] Specifically, when the main driving screen includes the instrument screen and the central control screen, the adjustment priority of the central control screen can be determined to be higher than the adjustment priority of the instrument screen to ensure that the main driving user can clearly view the basic driving information of the vehicle. Alternatively, the adjustment priorities of the instrument screen and the central control screen are determined to be at the same level, that is, both are adjusted at the same time.

[0177] Optionally, the implementation of S403 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0180] Optionally, the implementation of S404 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0181] S405, determine whether the co-pilot ceiling screen is in a lit state; if so, execute S406; if not, execute S407.

[0182] Exemplarily, when the co-pilot screen includes a co-pilot entertainment screen and a co-pilot ceiling screen, if the user position includes the co-pilot position, it can be further determined whether the co-pilot ceiling screen is in a lit state.

[0183] Optionally, the implementation of S405 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0184] S406, obtaining the visual area of ​​the co-pilot user, and determining the image quality adjustment order of the front screen according to the visual area.

[0185] Exemplarily, if the co-pilot ceiling screen is in a lit state, the co-pilot user's field of vision is obtained, and the image quality adjustment order of the front screen is determined according to the co-pilot user's field of vision.

[0186] Optionally, when the co-pilot user's sight area is on the co-pilot entertainment screen, the image quality adjustment order is determined to be the main driver screen>co-pilot ceiling screen>co-pilot entertainment screen. When the co-pilot user's sight area is on the co-pilot ceiling screen, the image quality adjustment order is determined to be the main driver screen>co-pilot entertainment screen>co-pilot ceiling screen.

[0187] Optionally, the implementation of S406 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0188] S407, determining the order of adjusting the image quality of the front screens is as follows: main driver screen > co-driver entertainment screen.

[0189] Exemplarily, when the co-pilot ceiling screen is not in a lit state, the image quality adjustment order of the front screens is determined to be main driver screen > co-pilot entertainment screen.

[0190] Optionally, the implementation of S407 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0191] S408, determine whether there is a user in the back row; if so, execute S409; if not, execute S410.

[0192] Exemplarily, when the user position does not include the co-pilot position, that is, when there is no user in the front row area, it is detected whether there is a user in the back row.

[0193] Optionally, the implementation of S408 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0194] S409, determining the order of adjusting the image quality is main driver's screen > co-driver's screen.

[0195] For example, when there are rear-seat users in the vehicle cabin, the rear-seat users may use the front passenger screen, and the order of image quality adjustment is determined to be main driver screen > passenger screen.

[0196] Optionally, the implementation of S409 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0197] S410, control the co-pilot screen to turn off.

[0198] For example, when there is no user in the vehicle cabin, the co-pilot screen can be controlled to turn off to achieve vehicle energy saving.

[0199] Optionally, the implementation of S410 can refer to Figure 2 The relevant description of S302 in the present application embodiment will not be repeated here.

[0200] S411, based on the image quality adjustment sequence, adjusting the current image quality configuration parameters of the target screen to the target image quality configuration parameters.

[0201] Among them, the energy consumption corresponding to the target image quality configuration parameter is less than the energy consumption corresponding to the current image quality configuration parameter.

[0202] Exemplarily, after determining the image quality adjustment sequence of the target screens in the front area, the current image quality configuration parameters of the target screens are adjusted to the target image quality configuration parameters in sequence according to the image quality adjustment sequence.

[0203] Optionally, the implementation of S411 can refer to Figure 2 The relevant description of S303 in the present application embodiment is not repeated here.

[0204] In summary, in the embodiment of the present application, by obtaining the user position in the front area of ​​the vehicle cabin, the picture quality adjustment order between the target screens in the lit state is determined; by judging whether there is a main driving user, a co-pilot user and a rear user, the corresponding picture quality adjustment order is determined, which can not only meet the usage requirements of different users for the target screens, but also achieve vehicle energy saving by adjusting the picture quality configuration parameters, and avoid multiple target screens running with higher energy consumption picture quality configuration parameters, resulting in rapid consumption of vehicle energy and affecting the normal driving of the vehicle.

[0205] Figure 5 This is a schematic flow chart of another vehicle control method provided by an embodiment of the present application. It should be understood that the method can be applied to a vehicle; or, applied to a processor in a vehicle; or, applied to a chip in a processor mounted in a vehicle.

[0206] For example, Figure 5 As shown, the method 500 includes the following steps S501-S505.

[0207] S501, when it is detected that the vehicle has an energy-saving demand, obtain the user position in the rear area of ​​the vehicle cabin, the target screen in the lit state, and the user type of the rear user.

[0208] Exemplarily, the energy consumption parameters of the vehicle (e.g., battery charge, remaining fuel, etc.) are monitored.
