[0061] Figure 5 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation
[0062] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0063] Figure 1 This is an exemplary embodiment illustrating a vehicle theater system control method, which can be applied to a vehicle, the vehicle including, for example... Figure 2 The vehicle-mounted cinema system 20 shown herein, the method can be used to control, for example... Figure 2 The vehicle theater system 20 shown includes a human-machine interface 21, a head-up display 22, a window with adjustable light transmittance 23, interior lighting equipment 24, an interior camera 25, a front-view camera 26, and a control device 30, to realize the vehicle theater mode.
[0064] Specifically, the subject executing this method can be an electronic device with information processing capabilities configured on the vehicle, such as a body control module or an electronic control unit, or an electronic device with information processing capabilities in the vehicle theater system, such as the control device 30 in the vehicle theater system 20. This disclosure does not limit the specific implementation of this method.
[0065] The embodiments disclosed herein are as follows Figure 2 For example, the control device 30 is used as the execution subject of the vehicle theater system control method. It is connected to each unit in the vehicle theater system 20 to acquire and process information from each unit and control each unit in order to realize the steps of the vehicle theater system control method.
[0066] like Figure 1 As shown, the vehicle theater system control method includes the following steps:
[0067] S101. In response to the user's cinema mode operation, acquire the illuminance in the direction of the vehicle's front and the illuminance inside the vehicle.
[0068] The user's cinema mode operation can be an operation performed by the user on the human-machine interface 21. The human-machine interface 21 can be a device including a display screen, which may be located on the vehicle's center console. The human-machine interface 21 may also include a voice recognition device. The user's operation to activate cinema mode on the human-machine interface 21 can be either clicking a button on the display screen or issuing a voice command. The vehicle's voice recognition device recognizes the voice command and matches it with the voice command to activate cinema mode, thus confirming that the user has activated cinema mode on the human-machine interface 21. In addition, the illuminance in the direction of the vehicle's front can be obtained through the forward-facing camera 26, and the illuminance inside the vehicle can be obtained through the in-vehicle camera 25.
[0069] S102. Control the light transmittance of the window 23 and / or the brightness of the interior lighting device 24 according to the illuminance in the direction of the vehicle front, the illuminance inside the vehicle, and the preset illuminance.
[0070] Among them, the car window can be Figure 2 The light transmittance of the windows 23 is adjustable. Windows 23 may include a sunroof, front and rear windshields, and retractable windows around the vehicle. The preset illuminance can be 50 lux or 40 lux, and the specific value can be based on the user's setting or the default optimal viewing illuminance setting.
[0071] S103. Control the head-up display device 22 to display preset content.
[0072] The preset content can be, for example, a splash screen ad animation, a user-defined selfie, an album cover, or a video, etc. This disclosure does not limit the types of information in the preset content.
[0073] In some optional embodiments, the preset illuminance is determined based on the brightness information of the preset content; or, the preset content includes video, and the preset illuminance dynamically changes with the brightness information of each frame of the video. For example, when the preset content is album cover information, the preset illuminance only needs to be set once based on one frame of the album cover image; or, when the preset content is video information such as a movie, if the control device 30 detects that the brightness of the next frame of the preset content is high, the preset illuminance can be increased. This solution allows for a better match between ambient illuminance and screen illuminance, enhancing the user's immersive viewing experience.
[0074] As vehicle configurations become increasingly diverse, head-up displays (HUDs) 22 are being installed in more and more vehicles. Furthermore, because the HUD 22 projects a virtual image onto the windshield, the viewing experience is not limited by the size of the vehicle's interior space, resulting in a better playback effect. Additionally, the HUD 22 may include storage space for storing the aforementioned preset content data; alternatively, this data can be sent to the HUD 22 via mobile devices such as smartphones. Those skilled in the art will understand that once the HUD 22 is activated, it can automatically retrieve data from its own storage space or receive data from other units within the vehicle theater system 20, such as the control device 22, and display corresponding images based on that data.
[0075] In this embodiment, a head-up display device 22 is used as the display device for the vehicle theater, and the interior illuminance can be adjusted according to the illuminance in the direction of the vehicle's front and the interior illuminance. This not only eliminates the need to purchase separate equipment such as projectors and screens, but also improves the movie playback effect. At the same time, the user's viewing experience can be enhanced by adjusting the interior illuminance.
[0076] In some optional embodiments, controlling the light transmittance of the window 23 based on the illuminance in the direction of the vehicle's front, the illuminance inside the vehicle, and a preset illuminance includes:
[0077] When the illuminance inside the vehicle is greater than the preset illuminance, the vehicle interior lighting device 24 is controlled to be turned off.
[0078] The required light transmittance is calculated based on the ratio of the vehicle window 23 to the vehicle body area, the illuminance in the direction of the vehicle front, and the preset illuminance.
[0079] The light transmittance of the window 23 is adjusted according to the required light transmittance.
[0080] Specifically, in one possible implementation, the required light transmittance can be calculated according to the following formula: T = L × tgt / (K*LX out )*100%, where T is the required light transmittance, LX tgt Indicates the preset illuminance, LX out This indicates the illuminance in the direction of the vehicle's front, and K represents the proportion of the vehicle's surface area to the area of the windows (23). The value of K is generally between 0.3 and 0.7. The preset illuminance is LX. tgt 50 lux, frontal illuminance (LX) out Taking 1000 lux and K value of 0.5 as an example, T = 50 / (1000 * 0.5) * 100% = 10%, that is, the required light transmittance is 10%.
[0081] By adopting this solution, when the illuminance inside the vehicle is high, such as during a daytime with strong sunlight, the light transmittance of window 23 can be adjusted so that the illuminance inside the vehicle approaches the preset illuminance, thereby improving the user's movie-watching experience.
[0082] In some alternative embodiments, controlling the brightness of the in-vehicle lighting device 24 based on the illuminance in the direction of the vehicle's front, the illuminance inside the vehicle, and a preset illuminance includes:
[0083] When the illuminance at the front of the vehicle is less than a preset illuminance threshold and the illuminance inside the vehicle is less than the preset illuminance, the interior lighting device 24 is turned on; and,
[0084] The brightness of the in-vehicle lighting device 24 is adjusted according to the difference between the in-vehicle illuminance and the preset illuminance.
[0085] By adopting this solution, when the illuminance inside the vehicle is low, such as at night, the brightness of the vehicle's interior lighting equipment 24 can be adjusted to make the illuminance inside the vehicle approach the preset illuminance, so that users can have a better experience when watching movies.
[0086] In some embodiments, the interior lighting device 24 includes hue-adjustable ambient lighting, and the method further includes:
[0087] Obtain the color tone information of the image containing the preset content;
[0088] The ambient light's hue is adjusted based on the hue information.
[0089] For example, when the preset content is video information, if the control device 30 detects that the hue information representing blue occupies 70% of the area in the frame of the preset content to be played on the head-up display device 22 in the next frame, then the ambient light can be controlled to display blue when the head-up display device 22 plays the next frame; if the hue information representing red occupies 70% of the area in the next frame, then the ambient light can be controlled to display red when the head-up display device 22 plays the next frame, so that the ambient hue of the atmosphere matches the playing picture better, thereby improving the user's immersion in the movie.
[0090] In some alternative embodiments, before acquiring the headlight illuminance outside the vehicle and the interior illuminance within the vehicle space, the method further includes:
[0091] Determine if the conditions for activating Cinema Mode are met;
[0092] The conditions for activating the cinema mode include one or more of the following:
[0093] The parking location of the vehicle meets the preset conditions;
[0094] The state of charge of the vehicle's power battery is greater than a preset charge threshold.
[0095] The vehicle is currently in park.
[0096] The head-up display device 22 is not faulty;
[0097] The illuminance in the direction of the vehicle's front is less than a preset illuminance threshold.
[0098] Those skilled in the art will understand that modern high-precision maps possess sub-meter level positioning capabilities, road-level and lane-level planning capabilities, and lane-level guidance capabilities. Preset conditions for vehicle parking locations can include the vehicle being in an open area without no-parking signs. Additionally, it can determine whether the vehicle is in a poorly ventilated location, such as an underground parking garage. By determining whether the vehicle's parking location meets these preset conditions, user safety during movie viewing can be ensured, avoiding risks such as traffic accidents or carbon monoxide poisoning.
[0099] In addition, the preset illuminance threshold can be 1000 lux. It should be understood that when the illuminance in the direction of the vehicle's front is too high, the viewing experience through the head-up display device 22 will be affected. Therefore, by ensuring that the illuminance in the direction of the vehicle's front is less than the preset illuminance threshold, it can be ensured that the lighting in the direction of the vehicle's front will not affect the user's viewing experience, thereby improving the user's viewing experience.
[0100] Optionally, the method further includes:
[0101] If, during the display of preset content on the head-up display device 22, it is detected that there are no passengers in the front or rear seats of the vehicle, the head-up display device 22 is controlled to pause the display. If, upon detecting that a passenger has returned to the vehicle, the head-up display device 22 is controlled to resume the display.
[0102] The vehicle can be equipped with a pressure sensor on each seat, and the occupancy status inside the vehicle can be determined based on the signals detected by the pressure sensors.
[0103] This solution allows the system to automatically pause playback when there are no passengers in the vehicle and resume playback when passengers return, making the vehicle cinema system more intelligent.
[0104] Optionally, in response to the cinema mode operation, the method further includes:
[0105] If it is determined that there are no passengers in the front seats of the vehicle, adjust the backrest of the front seats to a preset backrest angle; and / or,
[0106] If it is determined that there are no passengers in the rear seats of the vehicle, adjust the front seats to a preset seat position and adjust the steering wheel to a preset steering wheel position; and / or,
[0107] Close the vehicle doors, windows, and sunroof in the aforementioned window 23; and / or,
[0108] The vehicle's air conditioning system is turned on with the preset air conditioning temperature as the target temperature, and the air conditioning system is adjusted to the external circulation mode.
[0109] The preset backrest angle, preset seat position, and preset steering wheel position can be the optimal viewing angle and position set by default when the vehicle leaves the factory, or they can be adjusted by the user according to their specific usage. The preset air conditioning temperature can be 24 degrees Celsius, or it can be set by the user according to their usage habits; this disclosure does not limit this setting.
[0110] This solution detects passenger seating arrangements and adjusts the seats and steering wheel accordingly. This not only creates more space for maximum comfort but also prevents obstruction of view by the seats or steering wheel, enhancing the viewing experience. Furthermore, when the user activates cinema mode, closing the windows (23) provides a more enclosed environment, reducing external interference. Turning on the air conditioning prevents stuffiness inside the vehicle due to the enclosed space, further improving the viewing experience.
[0111] Optionally, the control head-up display device 22 displays preset content including:
[0112] The backlight brightness of the head-up display device 22 is determined based on the illuminance in the direction of the vehicle head.
[0113] The head-up display device 22 is controlled to display the preset content at the backlight brightness.
[0114] Specifically, the backlight brightness of the head-up display 22 can be six times that of the illuminance in the direction of the vehicle's front. By adopting this solution, the backlight brightness of the head-up display 22 can be adjusted according to the illuminance in the direction of the vehicle's front, minimizing the impact of the light from the vehicle's front on the user's viewing experience and making the viewing experience closer to that of a movie theater.
[0115] In some other embodiments, the vehicle theater system 20 also includes a communication device, allowing the vehicle to communicate with portable electronic devices such as mobile phones. The vehicle can control the vehicle theater system based on operations performed by the user on the mobile phone. Specifically, the communication device can be connected to a control device 30, enabling the control device 30 to obtain relevant operations performed by the user on the mobile phone or other portable electronic device via the communication device.
