[0029] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0030] A control device and method for in-vehicle multimedia according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the vehicle-mounted multimedia control device includes:

[0032] The housing 1 is surrounded by a plurality of panels 11 and has a receiving cavity formed therein;

[0033] A main control board 2 is installed on one side of any panel 11 located in the accommodating cavity, and a gravity sensor 21, a communication module 22 and a control chip 23 are installed on the main control board 2. The gravity sensor 21 is used to monitor the gravity data of the control device and send the gravity data to the control chip 23; the control chip 23 is used to determine the target panel on the current shell 1 that is oriented as the target orientation based on the gravity data, and send the target identification information of the target panel to the target vehicle through the communication module 22, and the target vehicle adjusts the color of the vehicle atmosphere light and / or determines the music recommendation type to be played based on the target identification information and the first preset corresponding relationship;

[0034] Among them, the first preset correspondence includes the correspondence between the identification information of each panel 11 and the color of the vehicle atmosphere light, between the identification information of each panel 11 and the music recommendation type, or between the identification information of each panel 11 and the color of the vehicle atmosphere light and the music recommendation type.

[0035] In some embodiments, the housing 1 of the vehicle-mounted multimedia control device is surrounded by a plurality of panels 11 , and a receiving cavity is formed inside the housing 1 , in which electronic components can be installed.

[0036] For example, as an example, Figure 1 and Figure 2 As shown, the housing 1 of the control device is surrounded by 6 panels 11. A main control board 2 is installed inside the accommodating cavity surrounded by the housing 1, wherein the main control board 2 can be installed on any panel 11 by a detachable connection or a non-detachable connection. The detachable connection method can be screw connection, and the non-detachable method can be welding. For example, the main control board 2 can be directly installed by screwing the mounting holes 24 and the mounting studs on the panel 11.

[0037] The main control board 2 can be a printed circuit board assembly (PCB-A) board. The PCB-A board refers to a printed circuit board on which various electronic components are assembled through processes such as surface mounting technology or through-hole insertion technology to achieve specific functions. The PCB-A board has the characteristics of small size, light weight, and high reliability.

[0038] The main control board 2 is equipped with a gravity sensor 21, a communication module 22 and a control chip 23, wherein the gravity sensor 21 is connected to the control chip 23, and the control chip 23 communicates with the vehicle through the communication module 22. The communication module 22 is used to communicate between the control device and the target vehicle, and the communication module 22 can be a wireless communication module such as a Bluetooth module, a Wi-Fi module, or a wired communication module 22 (such as a serial communication module). The gravity sensor 21, the communication module 22 and the control chip 23 can be installed on the side of the main control board 2 that faces away from the housing 1 to ensure a larger installation space.

[0039] The control device can rotate to change the orientation of each panel 11. The gravity sensor 21 can monitor the gravity data of the control device in real time, and send the gravity data to the control chip 23. The control chip 23 determines the orientation of each panel 11 according to the received gravity data, thereby determining the target panel on the current shell 1 that is oriented as the target orientation. Among them, the orientation of the panel 11 can be the orientation of the side of each panel 11 located outside the accommodating cavity, or it can be the orientation of the side of each panel 11 located inside the accommodating cavity, as long as the orientation of each panel 11 is defined consistently; the target orientation can be upward, downward, or leftward, and is not specifically limited here. For example, as an example, a panel 11 whose side is oriented vertically upward outside the accommodating cavity can be determined as the target panel, that is, the control chip 23 determines the panel 11 whose side is oriented vertically upward outside the accommodating cavity as the target panel based on the gravity data.

[0040] The control chip 23 stores the corresponding relationship between each panel 11 and its identification information. After determining the target panel, the target identification information corresponding to the target panel can be determined, and the target identification information of the target panel is sent to the target vehicle through the communication module 22. The target identification information can be the number or code of the target panel. In the control device, each panel corresponds to a unique number or code for distinguishing different panels.

[0041] A first preset correspondence is pre-stored in the target vehicle, which may include the correspondence between the identification information of each panel and the color of the vehicle's ambient light, the correspondence between the identification information of each panel and the type of music recommendation, and the correspondence between the identification information of each panel and the color of the vehicle's ambient light and the type of music recommendation.

[0042] For example, if the identification information of a certain panel is "soothing music, blue", then when the panel is oriented in the target orientation (for example, the outer side is facing upward), the music recommendation type can be determined as "soothing music" and the color of the vehicle's ambient light is blue.

[0043] For another example, the control device is a hexahedron, and each panel in the hexahedron of the control device corresponds to a panel identification information, and each panel identification information corresponds to a vehicle ambient light color and a music type. The positive integer starting from A1 is determined as the panel identification information of the panel. The first preset correspondence relationship can be: the first panel A1-color-random music type, the second panel A2-white-pure music type, the third panel A3-red-cheerful music type, the fourth panel A4-blue-soothing music type, the fifth panel A5-green-fresh music type, the sixth panel A6-purple-classical music type. It can be seen that the panel with panel identification information A3 corresponds to the vehicle ambient light color of red, and the corresponding music recommendation type is the cheerful music type.

[0044] In addition, the user of the target vehicle can set a first preset correspondence. For example, the default first preset correspondence can be changed to be dynamically adjusted according to changes in seasons and / or scenes. For example, in winter, the fourth panel A4-blue-soothing music type is changed to the fourth panel A4-warm yellow-soothing music type, that is, the ambient light color corresponding to soothing music in winter can be set to warm yellow.

[0045] In addition, the playback of the video can be controlled by the control device.

[0046] After receiving the target identification information, the target vehicle can determine the target color of the vehicle atmosphere light corresponding to the target identification information based on the target identification information and the first preset correspondence, thereby controlling the color of the vehicle atmosphere light to be adjusted to the target color; or determine the target music recommendation type corresponding to the target identification information based on the target identification information and the first preset correspondence, thereby controlling the music recommendation type of the music to be played to be adjusted to the target recommendation type, so that the music of the target recommendation type can be played when playing music; or determine the target color and target recommendation type of the vehicle atmosphere light corresponding to the target identification information based on the target identification information and the first preset correspondence, thereby controlling the color of the vehicle atmosphere light to be adjusted to the target color, and controlling the music recommendation type of the music to be played to be adjusted to the target recommendation type.

[0047] In this way, this embodiment uses the above-mentioned control device so that when the user needs to adjust the color of the vehicle's ambient light and / or determine the music recommendation type to be played, the user only needs to rotate the control device to change the target panel of the control device housing, thereby being able to control the music recommendation type and adjust the color of the vehicle's ambient light. This realizes the rapid change of the vehicle's ambient light color and the change of the music type by rotating the control device, and adds a new and convenient operation interaction method, making the interaction between the user and the vehicle's multimedia more convenient, and solving the problem that it is inconvenient for rear passengers or co-pilot passengers in the vehicle to adjust the music type or the vehicle's ambient light.

[0048] In some embodiments, a light panel is installed on one side of each panel located in the accommodating cavity, and the light on the light panel faces the panel and the light can penetrate the corresponding panel; wherein,

[0049] The light colors of each light panel are different, and for the same panel, the difference between the color hue of the vehicle ambient light corresponding to the panel and the color hue of the light color corresponding to the panel is less than a preset difference value.

[0050] Among them, a light board is installed on one side of each panel located in the accommodating cavity, and a light is installed on the light board, that is, each panel corresponds to a light board. The light on the light board faces the panel, and the light can pass through the corresponding panel. For example, the panel is a light-transmitting panel or a light-transmitting hole is set on the panel. The light-transmitting panel can be a material with a certain degree of transparency or a fully transparent material, such as a translucent panel or a fully transparent panel.

[0051] The lights on each light board can be light emitting diode (LED) light strips or light beads. The LED light strips or light beads can be arranged regularly on the light board, for example, arranged around the edges of the light board, or arranged in rows and columns or in a circle.

[0052] For example, Figure 3 As shown, a lighting panel is installed on one side of each panel located in the accommodating cavity. When the shell is a hexahedron, the lighting panel includes lighting panel 31, lighting panel 32, lighting panel 33, lighting panel 34, lighting panel 35 and lighting panel 36.

[0053] The lighting board can be a PCB-A board.

[0054] In addition, in the control device, the light colors on each light panel are different, and the light colors may include red, green, blue, and various intermediate colors mixed together, and may also include colored lights that randomly change the light colors.

[0055] Each lighting panel may further include four mounting holes 311 for connecting the lighting panels.

[0056] In order to accurately control the color, the LED light strips or lamp beads on the lighting panel can be managed through the color management algorithm. The color management algorithm can parse and generate color instructions that are accurate to specific hue, saturation, and brightness. For example, the color can be adjusted through the color model (Hue, Saturation, Value, HSV for short) or the color model (Hue-Saturation-Lightness, HSL) to improve the variability of the light color.

[0057] The difference between the color hue of the vehicle ambient light corresponding to the same panel 11 and the color hue of the light color corresponding to the panel 11 is less than the preset difference value, that is, the difference between the two is within a small range, so as to form a harmonious and complete ambient light environment between the vehicle ambient light and the control device.

[0058] Among them, the difference value of color hue can be measured according to the Euclidean distance or color difference formula in the calculated color space, such as ΔE*ab, wherein ΔE*ab represents a color difference calculation formula based on the Lab color space, which is a commonly used color space composed of brightness (L), red green (a), and blue yellow (b).

[0059] According to the technical solution provided in the embodiment of the present application, by controlling the difference between the color of each light and the color hue of the vehicle's ambient light to be less than a preset difference value, the visual uniformity and coordination of the target vehicle's interior lighting environment is ensured, thereby improving the user's visual experience of using the target vehicle and enhancing the personalization and emotionality of the user experience.

[0060] In some embodiments, when the control device controls the music player to play music, the control chip is also used to control the light of the light panel corresponding to the target panel to move with the music.

[0061] The control chip of the control device can control the light panel on the target panel. When the music player is controlled by the control device to play music, the control chip can also control the light of the light panel of the target panel to move rhythmically with the music. The control chip can receive a rhythm signal corresponding to the rhythm of the music sent by the target vehicle, and control the light of the light panel of the target panel to move rhythmically according to the rhythm signal. The music rhythm may include rhythm, volume, pitch change, etc., and the rhythm signal may include instructions to change the brightness, flashing frequency or dynamic effects of the lights, etc., which can match the rhythm and emotional changes of the music.

[0062] For example, when the music tempo speeds up, the lights can become brighter and flash faster, while in a soft melody, the lights can change brightness gradually and gently.

[0063] In addition, the target vehicle can also control the vehicle's ambient lights to move with the music. The rhythm of the vehicle's ambient lights corresponding to the same music is the same as the rhythm of the control device, making the vehicle's atmosphere harmonious.

[0064] According to the technical solution provided in the embodiment of the present application, the synchronized rhythm of light and music creates a more immersive audio-visual enjoyment space for users, so that music playback is not only limited to the auditory experience, but also enriches the emotional expression through the addition of visual elements, improves the overall entertainment and viewing experience, and can also customize the interactive effects of light and music according to different environments and needs to meet the diverse scene needs of users.

[0065] In some embodiments, the control chip is also used to control the light brightness of the light panel installed on the target panel to be adjusted to a first preset brightness, and to control the light brightness of other light panels to be adjusted to a second preset brightness, and when the light of the light panel corresponding to the current target panel is a multi-color light, control the multi-color light to change color periodically and randomly; wherein the first preset brightness is greater than the second preset brightness.

[0066] Figure 4 A schematic diagram of a lighting panel provided in an embodiment of the present application, such as Figure 4 As shown, the lighting panel is provided with mounting holes 311 and LED lamp beads 312. The LED lamp beads can be arranged parallel to the edge of the panel. The mounting holes 311 are located at each corner of the panel and can be directly installed with screws to the shell.

[0067] The control chip is also used to control the light brightness corresponding to the light board of the target panel to be adjusted to a first preset brightness after determining the target panel, and to control the light brightness corresponding to other light boards except the light board corresponding to the target panel to be adjusted to a second preset brightness, that is, to adjust the light brightness of the panel facing the target direction in the control device to the first preset brightness, and to adjust the light brightness of the light boards corresponding to other panels to the second preset brightness.

[0068] For example, assuming that the light color corresponding to the current target panel is green, the gravity sensor receives gravity data, the target panel changes, and the light color corresponding to the changed target panel is blue, the brightness of the blue light is adjusted to the first preset brightness, and the brightness of the lights corresponding to the colors other than blue, including green, is adjusted to a second preset brightness that is less than the first preset brightness.

[0069] The light brightness can be adjusted by using a control chip using a digital-to-analog converter (DAC) or pulse-width modulation (PWM) technology to adjust the current or duty cycle of the LED lamp beads in each light panel.

[0070] In addition, when the light of the light board corresponding to the current target panel is a multi-color light, the control chip can control the multi-color light to randomly change periodically within a preset color range at a certain time interval, that is, control the multi-color light to change color periodically and randomly.

[0071] For example, multi-color lights periodically change colors randomly between blue, yellow, red, green, and purple, and the alternation between the two colors is smooth and soft.

[0072] In addition, when the control device is turned on but no connection is established with the target vehicle or linkage is established with the music player, the control chip controls the light of the light panel corresponding to the target panel to periodically, irregularly and smoothly adjust the light display brightness, wherein the light display brightness is not greater than the first preset brightness and not less than the second preset brightness.

[0073] Figure 5 is another schematic diagram of a lighting panel provided in an embodiment of the present application, such as Figure 5 As shown, the light board includes a mounting hole 311, an LED lamp bead 312 and a light control chip 313. The LED lamp bead 312 and the light control chip 313 are mounted on each panel through the mounting hole 311. The light control chip 313 can receive the light control instruction sent by the control chip and control the lighting of the LED lamp bead according to the light control instruction. The light control chip can also send the real-time information of the LED lamp bead to the control chip to synchronize the information of the light board with the control chip. Of course, the control chip can also directly control the lighting of the LED lamp bead.

[0074] According to the technical solution provided in the embodiment of the present application, by distinguishing the light brightness settings of the target panel and other panels, the overall lighting in the car is made more coordinated, while reducing energy consumption in non-critical areas and achieving rational use of energy. The periodic random color changing function of the multi-color light enables the light of the control device to be flexibly adjusted according to the occasion or emotional needs, thereby enhancing the interactivity and fun of the environment, bringing users a richer and more delicate sensory experience, and enhancing the overall immersion and satisfaction.

[0075] In some embodiments, the control device also includes a power module and at least one power touch key; the power module is installed in the accommodating cavity to supply power to various electrical components of the control device; the power touch key is arranged at the corner position of the shell to control the connection between the power module and various electrical components.

[0076] The control device also includes a power module and at least one power touch key, wherein the power module is installed in the accommodating cavity, for example, it can be installed on the side of any lighting panel facing away from the panel or on the side of the main control board facing away from the panel, so that the power module can effectively dissipate heat to avoid mutual interference with the heat generated by the lighting board or the main control board, and also optimizes the space utilization in the accommodating cavity, making the structure in the control device more compact and reasonable.

[0077] The side of the light panel facing away from the panel is the side where no LED light strip or light beads are installed.

[0078] Among them, the power supply module can adopt a high-efficiency conversion circuit design to stably provide the required working voltage and current for each electrical component in the accommodating cavity, thereby ensuring the stable operation and high-efficiency performance of the control device. The electrical components include LED light strips or lamp beads, gravity sensors, communication modules and control chips.

[0079] In addition, the power touch key is arranged at the corner of the control device housing to control the connection between the power module and various electrical components, so that the user can naturally touch it when holding or operating the control device, thereby improving the user experience.

[0080] For example, in one example, Figure 6 A schematic diagram of a power touch key of a control device provided in an embodiment of the present disclosure, such as Figure 6 As shown, the power touch key 4 is installed at the common point of three adjacent panels. The outside of the control device can be set as a pressable triangular button, and the power touch key 4 can be directly controlled by touch.

[0081] Among them, the power touch key 4 can be realized by capacitive sensing, and can realize the switching of the power on and off or the power state without physical pressing. It has high response sensitivity and can immediately feedback the user's operation intention, thereby enhancing the interactivity of the system.

[0082] In addition, the accommodating cavity may also include a built-in battery for storing electricity for operating the electrical components of the control device.

[0083] According to the technical solution provided in the embodiment of the present application, the power touch key can control the connectivity between the power module and various electrical components, that is, it can control the opening and closing of the control device. The power module can enable various electrical components to obtain a stable and continuous power supply, thereby improving the operating stability and reliability of the control device.

[0084] In some embodiments, the number of the power touch keys is two, and the two power touch keys are installed at any diagonal position of the housing; wherein,

[0085] When the control device is in the off state, when the two power touch keys are touched at the same time and the duration of the touch is not less than the first preset duration, the control power module is connected to each electrical component to put the control device into the on state;

[0086] When the control device is in the on state, when the two power touch keys are touched at the same time and the duration of the touch is not less than the first preset duration, the control power module is disconnected from the electrical components to switch the control device to the off state.

[0087] The number of power touch keys can be two, and the two power touch keys can be installed at any diagonal position of the shell, so as to ensure that when any panel of the control device is the target panel, the user can easily touch the power touch key, making it more convenient and accurate to control the vehicle multimedia control device through the power touch key, and installing it at a diagonal position can prevent accidental touch and misoperation.

[0088] The two power touch keys can be connected to the internal control circuit through conductive materials. The control circuit may include a timer module for recording the duration of the two power touch keys being touched. The control circuit may also include a status detection module for detecting whether the control device is currently in an on state.

[0089] When the control device is in the off state, the two power touch keys are touched at the same time and the duration of the touch is not less than the first preset duration. The control circuit can control the power module to achieve connectivity with each electrical component, so that the control device switches from the off state to the on state.

[0090] When the control device is in the on state, when the two power touch keys are touched at the same time and the duration of the touch is not less than the first preset duration, the control circuit controls the power module to disconnect from each electrical component, so that the control device switches from the on state to the off state.

[0091] Among them, the first preset time length can be 3 seconds, that is, when it is detected that the two power touch keys are touched at the same time, and the duration of the simultaneous touching is not less than 3 seconds, the on state (off state) of the control device is switched to the off state (on state).

[0092] In some examples, when the control device is in the off state, after two power touch keys are touched at the same time, the power module is connected to each electrical component to make the control device enter the on state, and after the two power touch keys are touched at the same time when the control device is in the on state, the power module is disconnected from each electrical component to switch the control device to the off state. In other examples, when the control device is in the off state, after any of the two power touch keys are touched, the power module is connected to each electrical component to make the control device enter the on state, and after any of the power touch keys is touched when the control device is in the on state, the power module is disconnected from each electrical component. The present application does not specifically limit the way in which the power touch key controls the power module to be connected to each electrical component.

[0093] According to the technical solution provided in the embodiment of the present application, by installing two power touch keys at the diagonal positions of the shell, the user can more easily operate the power touch key with both hands or one hand, and in the case of the diagonal position, it can ensure that when any panel of the control device is the target panel, there is a power touch key in a position that is convenient for the user to operate, thereby improving the accuracy of operating the control device and the safety of the equipment, while optimizing the user experience of using the control device.

[0094] In some embodiments, a charging contact is provided at the center of the outer surface of each panel of the housing, and the charging contact is connected to the power module;

[0095] When the charging contacts are connected to the charging seat on the target vehicle, the charging seat charges the power module through the charging contacts.

[0096] Figure 7 A schematic diagram of the coordination between a charging contact on a control device and a charging seat on a vehicle provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the charging contact 5 is at the center point of each panel 11 in the control device, which is convenient for connecting with the charging base 6.

[0097] A charging contact 5 is provided at the center point of the outer surface of each panel of the housing. The charging contact 5 passes through the panel and is connected to a power module (not shown in the figure).

[0098] In addition, the charging contacts 5 take into account the compatibility with the charging seat on the target vehicle to ensure that the charging seat 6 on the target vehicle can be seamlessly connected with the charging contacts 5 on the housing. When the housing is properly installed or close to the charging seat of the target vehicle, the charging contacts 5 are aligned and in close contact with the charging seat on the target vehicle.

[0099] Among them, the charging base is a key component for transmitting electrical energy to the target vehicle, and its design follows the standardized interface protocol, including physical dimensions, electrical characteristics, and communication protocols.

[0100] In addition, the charging contacts 5 can be assisted by magnetic force to align or mechanically guide structures to automatically align and closely contact with the charging socket on the target vehicle, thereby improving the accuracy and convenience of the connection between the charging contacts 5 and the charging socket.

[0101] According to the technical solution provided in the embodiment of the present application, a charging contact 6 is provided at the center of the outer surface of each panel of the shell, so that the control device can be charged through any surface to ensure the operation of the control device. Charging through the charging contact 6 makes the use of the control device more flexible.

[0102] In some embodiments, the communication module is a Bluetooth module;

[0103] The control device pairs the Bluetooth module of the control device with the Bluetooth module of the target vehicle to establish a connection with the target vehicle;

[0104] When the control device is in an uncharged state within the second preset time period and the control chip does not detect a change in gravity data within the second preset time period, the control device enters a dormant state to disconnect from the target vehicle;

[0105] When the control device is in a dormant state and the control device starts to charge or the control chip detects a change in gravity data, the control device enters a wake-up state to reconnect with the target vehicle.

[0106] In some examples, the communication module may be a Bluetooth module, through which the control device can pair with the Bluetooth module of the target vehicle to establish a connection with the target vehicle, wherein the pairing process includes steps such as device discovery, service discovery, and characteristic value reading and writing, which can ensure that the connection between the control device and the target vehicle is safe and reliable. After successful pairing, the control device and the target vehicle can exchange data through the corresponding Bluetooth module, such as sending control instructions.

[0107] The communication between the Bluetooth module of the control device and the Bluetooth module of the target vehicle may include:

[0108] If the control device is connected to the target vehicle for the first time, you need to open the Bluetooth setting interface of the target vehicle, find the name corresponding to the control device and pair it. After the pairing is successful, the control device can be connected to the target vehicle;

[0109] When the control device is turned on, if the control device and the target vehicle have been paired, the control device will automatically connect to the target vehicle;

[0110] When the control device is turned on and Bluetooth is turned on, if the control device cannot connect to the target vehicle, the user can choose to turn on the control device association in the control device setting panel of the target vehicle, and the control device will automatically connect to the target vehicle;

[0111] When the control device is connected to the target vehicle, the control device is automatically disconnected from the target vehicle after the control device is turned off;

[0112] When the control device is connected to the target vehicle, open the Bluetooth setting interface of the target vehicle, find the name corresponding to the control device and cancel the pairing, and the control device is disconnected from the target vehicle;

[0113] When the control device is connected to the target vehicle, the user can choose to disconnect the control device in the control device setting panel of the target vehicle, and the control device will automatically disconnect from the target vehicle;

[0114] When the control device is connected to the target vehicle, after the control device enters the dormant state, the control device is automatically disconnected from the target vehicle.

[0115] In addition, when the control device is in the on state, when the charging base is powered off for more than a second preset time period and the gravity sensor has no output of a state change within the second preset time period, the control device enters a sleep state and disconnects communication with the target vehicle.

[0116] Among them, the state of the control device also includes a sleep state, and whether the control device should enter the sleep state can be determined based on two key conditions: whether the control device is in an uncharged state within a second preset time period, and whether the control chip of the control device has not detected any changes in gravity data during this period.

[0117] If the above two conditions are met at the same time (not charged and no gravity data changes are detected), the control device will automatically enter the sleep state. In the sleep state, the Bluetooth module will suspend work and all non-essential circuits will be turned off to minimize energy consumption. At the same time, the connection with the target vehicle will be temporarily disconnected until the wake-up condition is met.

[0118] The wake-up conditions include the control device starting to charge, which indicates that the user is using or preparing to use the control device, so it is necessary to re-establish the connection; the control chip detects a change in gravity data, which indicates that the control device is moved or the user is operating (such as moving, rotating, etc.) the control device, which also indicates that it is necessary to restore the connection. When the above conditions are met at the same time, the control device wakes up from the sleep state, the Bluetooth module restarts, and tries to reconnect with the target vehicle to restore data communication and control functions.

[0119] According to the technical solution provided in the embodiment of the present application, in the sleep state, the control device can automatically disconnect from the target vehicle when not needed, reducing energy consumption during standby and extending battery life. When the sleep mode is converted to the wake-up state, the control device can respond to the wake-up state and re-establish the connection with the target vehicle, ensuring the immediacy and continuity of control and improving the user experience.

[0120] In some embodiments, when the control device is connected to the target vehicle, the control chip sends the target operation received by any power touch key to the target vehicle, so that the target vehicle determines the target control instruction for the music player based on the target operation and the second preset correspondence, and controls the music player based on the target control instruction;

[0121] The second preset corresponding relationship includes the corresponding relationship between the current playing state of the music player, the operation corresponding to the power touch key, and the control instruction.

[0122] Specifically, when the control device is connected to the target vehicle, the control chip sends the target operation received by any power touch key to the target vehicle, so that the target vehicle can determine the target control instruction for the music player according to the target operation and the second preset correspondence, and control the music player according to the target control instruction.

[0123] Among them, the target operation may include simultaneously touching the power touch key for a duration greater than the first preset duration, single-clicking any power touch key within the preset control time, double-clicking any power touch key within the preset control time, touching any power touch key three times within the preset control time, etc.

[0124] Among them, the control chip can instantly obtain and analyze the target operation from the power touch key, and send the target operation to the target vehicle through the communication module, so that the target vehicle controls the music player according to the target operation and the pre-stored second preset corresponding relationship.

[0125] The second preset corresponding relationship includes the corresponding relationship between the playing state of the music player, the operation corresponding to the power touch key and the control instruction.

[0126] The playing status of the music player can be play, pause, switch to next song, switch to previous song, etc.

[0127] For example, the second preset corresponding relationship may be:

[0128] When the control chip detects a first operation of clicking any power touch key within a preset control time, the first operation is sent to the target vehicle. If the target vehicle detects that the current playing state of the music player is a paused playing state, the music player is controlled to play music based on the corresponding relationship between the paused playing state, the first operation and the control music playing instruction. In addition, if the target vehicle detects that the current playing state of the music player is a playing state, the music player is controlled to pause the music playing based on the corresponding relationship between the playing state, the first operation and the control music pause playing instruction.

[0129] When the control chip detects a second operation of double-clicking any power touch key within a preset control time, the second operation is sent to the target vehicle. If the target vehicle detects that the current playing state of the music player is the playing state, the music player is controlled to switch the currently playing music to the next song based on the corresponding relationship between the playing state, the second operation and the instruction for controlling the music to switch to the next song.

[0130] When the control chip detects the third operation of touching any power touch key three times within the preset control time, the third operation is sent to the target vehicle. If the target vehicle detects that the current playing state of the music player is the playing state, based on the correspondence between the playing state, the third operation and the instruction to control the music to switch to the previous song, the music player is controlled to switch the currently playing music to the previous song.

[0131] In some examples, the control chip can also pre-store a second preset correspondence, and based on the correspondence between the operation corresponding to the power touch key in the second preset correspondence and the control instruction, convert the target operation received by any power touch key into a control instruction, and send the control instruction to the target vehicle. At this time, the target vehicle determines the final target control instruction based on the correspondence between the current play state of the music player and the control instruction in the second preset correspondence, and controls the music player based on the target control instruction. For example, when the control chip detects a first operation of clicking any power touch key within a preset control time, based on the correspondence between the first operation and playing music and the first operation and pausing music in the second preset correspondence, the first operation is converted into a play music instruction and a pause music instruction, and the play music instruction and the pause music instruction are sent to the target vehicle. The target vehicle detects that the current play state of the music player is paused at this time, then based on the correspondence between the pause state and the play music instruction in the second preset correspondence, the final target control instruction is determined to be play music.

[0132] According to the technical solution provided in the embodiment of the present application, users can control the in-car music player in a more intuitive and convenient way without having to distract themselves by looking for physical buttons or virtual buttons on the touch screen. The second preset correspondence can be customized according to user preferences, providing a personalized interactive experience for the vehicle and improving driving safety and operational convenience.

[0135] S901, receiving target identification information of a target panel sent by a control device of the vehicle-mounted multimedia;

[0136] The vehicle-side controller on the target vehicle receives the target identification information of the target panel sent by the control device of the vehicle-mounted multimedia, wherein the vehicle-side controller can receive the target identification information through the communication module of the target vehicle. The target identification information is usually a unique code used to distinguish different target panels of the control device.

[0137] The target panel is a panel on the housing of the control device that faces the target direction.

[0138] S902, adjusting the color of the vehicle ambient light and / or determining a target music recommendation type of the music to be played based on the target identification information and the first preset correspondence relationship;

[0139] The first preset corresponding relationship includes the correspondence between the identification information of each panel and the color of the vehicle atmosphere light, between the identification information of each panel and the music recommendation type, or between the identification information of each panel and the color of the vehicle atmosphere light and the music recommendation type; that is, the first preset corresponding relationship includes the correspondence between the identification information of each panel and the color of the vehicle atmosphere light, or includes the correspondence between the identification information of each panel and the music recommendation type, or includes the correspondence between the identification information of each panel and the color of the vehicle atmosphere light and the music recommendation type.

[0140] The vehicle-side controller searches according to the first preset correspondence based on the received target identification information to determine the color of the vehicle atmosphere light and / or the target music recommendation type corresponding to the target identification information in the first preset correspondence, and based on this, adjusts the color of the vehicle atmosphere light and / or determines the music recommendation type to be played as the target music recommendation type.

[0141] In addition, the color adjustment of the vehicle ambient light can be performed through the lighting module of the target vehicle to match the color corresponding to the target panel in the current control device.
