Based upon this description of the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without having inventive effort are within the scope of the present application.

[0033] It should be noted that like reference numerals and letters refer to like items in the accompanying drawings, and as a result, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings. The terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0034] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0035] Currently, a display screen such as a TFT liquid crystal screen is usually provided on a current automobile instrument panel, and a display screen such as a liquid crystal instrument and a vehicle display screen is provided on the display screen, a vice driver place of a part of vehicles is even provided with a vice driver entertainment screen, so as to realize a two-screen or even a three-screen design. These display screens can usually be used to display vehicle information or realize human-vehicle interaction, complete vehicle setting, and even can be used for passenger viewing, game, and other entertainment activities. On this basis, in order to optimize the interior appearance and enhance the visual experience of the vehicle passengers, a variety of background lights and atmosphere lights such as LED light strips, lamp beads, and other decorations are further provided near the two-screen or three-screen. Whether the display screen or the background light and atmosphere light, the display mode thereof can usually be adjusted by the vehicle passengers according to their own needs, for example, the working mode and the backlight brightness of the display screen are adjusted or the on-off, color, brightness, and the like of the background light and atmosphere light are adjusted.

[0036] In the prior in-vehicle device control scheme of display screen and background light, the related hardware devices usually include interior end devices and a cockpit controller, wherein the interior end devices usually include a display screen, a LVDS (Low-Voltage Differential Signaling) deserializer, an MCU (Microcontroller Unit), a background light and the like; and the cockpit controller usually includes a SOC (System on Chip), a LVDS transmitter and a LIN transmitter. The display screen is in communication connection with the LVDS deserializer, the LVDS deserializer is in communication connection with the SOC via the LVDS transmitter, and the LVDS deserializer is also in communication connection with the MCU, the SOC is also in communication connection with the LIN receiver via the LIN transmitter, the LIN receiver is also in communication connection with the MCU, and the MUC is also in communication connection with the display screen and the background light.

[0037] When the in-vehicle passenger needs to adjust the display mode of the display screen or the background light, an operation instruction can be issued by, for example, touching a corresponding virtual control button in the display screen, and the operation instruction can be sent to the SOC via the LVDS deserializer and the LVDS transmitter in turn, the SOC generates a control signal according to the operation instruction and a suitable preset coding rule, and the control signal is sent to the display screen via the LVDS transmitter, the LVDS deserializer and the MCU in turn to realize the control of the display screen, or the control signal is sent to the background light via the LIN transmitter, the LIN receiver and the MCU in turn to realize the control of the background light.

[0038] Therefore, in the prior in-vehicle device control scheme of display screen and background light, the LIN transmitter, the LIN receiver, the LVDS transmitter and the LVDS deserializer are needed, and the LIN bus is needed to realize the communication connection between the LIN transmitter and the LIN receiver, and the LVDS bus is needed to realize the communication connection between the LVDS transmitter and the LVDS deserializer, that is, at least two buses and at least two preset communication protocols are needed to realize the control of the in-vehicle devices such as the display screen and the background light, and the hardware structure and the software control logic are relatively complex. The in-vehicle device control method provided in the present application aims to simplify the hardware structure and the software control logic in the in-vehicle device control scheme of display screen and background light.

[0039] Figure 1 The in-vehicle device communication connection principle diagram provided in an embodiment of the present application is shown in Figure 1The related hardware devices in the embodiment may, for example, include an interior device and a cockpit controller, which may, for example, be a computer or the like device having data processing capability. The interior device may, for example, include the in-vehicle device and a low-voltage differential signaling (LVDS) deserializer, a microcontroller unit (MCU), and the like. The in-vehicle device may, for example, include the display screen, a background light, and the like. The cockpit controller may, for example, include a system on chip (SOC) and an LVDS transmitter.

[0040] The display screen is in communication connection with the LVDS deserializer. The LVDS deserializer is in communication connection with the SOC via the LVDS transmitter. The LVDS deserializer is also in communication connection with the MCU. The MCU is also in communication connection with the display screen and the background light. The LVDS deserializer in the interior device and the LVDS transmitter in the cockpit controller may be in communication connection via a bus. That is, the cockpit controller may be in communication connection with the in-vehicle device, such as the display screen and the background light, via the LVDS deserializer and the MCU, and the like, by using a bus and a preset communication protocol.

[0041] For example, the display screen may be, but is not limited to, a TFT liquid crystal screen, and the like. The background light may be, but is not limited to, an LED light strip, a lamp bead, and the like. The SOC may be a system on chip having a communication function and a data processing function, and the like. The MCU may be a microcontroller unit having a communication function and a data processing function, and the like. The liquid crystal screen may be in communication connection with the LVDS deserializer via an LVDS wire harness. The LVDS deserializer and the LVDS transmitter may be in communication connection via an LVDS bus. The LVDS transmitter and the SOC and the LVDS deserializer and the MCU may be in communication connection via an I2C wire harness. It can be understood that, when the LVDS wire harness, the LVDS bus, and the I2C wire harness are used to realize communication connection between devices, the devices may be connected via corresponding LVDS interfaces and I2C interfaces. Alternatively, the devices may be wirelessly connected based on an LVDS protocol or an I2C protocol, which is not limited herein.

[0042] Of course, the above content is only an example. The types and models of the display screen, the background light, the SOC, the MCU, and the like, and the specific communication connection implementation manner may be selected and determined according to actual conditions, and are not limited by the content in the embodiment. Figure 1

[0043] ​On this basis, Figure 2 A flowchart of a vehicle interior device control method is provided for an embodiment of the present application. The method can be applied to the above-mentioned cockpit controller, which is connected to multiple vehicle interior devices through a bus using a preset communication protocol. Specifically, the method can be applied to the SOC in the above-mentioned cockpit controller. The cockpit controller being connected to multiple vehicle interior devices through a bus using a preset communication protocol can mean that the cockpit controller is connected to multiple vehicle interior devices through an MCU, an LVDS deserializer, and the like via a bus, as shown in FIG. 1. The method can include the following steps. Figure 2

[0044] S201, receiving an operation instruction obtained based on a user operation.

[0045] For example, the operation instruction obtained based on a user operation can be issued by a user, i.e., a vehicle occupant, through a corresponding virtual control button in a touch display screen, or by pressing a corresponding physical button or rotating a corresponding physical knob beside the display screen. The operation instruction can be transmitted to an LVDS deserializer through an LVDS harness between the display screen and the LVDS deserializer, and then transmitted to the cockpit controller through an LVDS bus between the LVDS deserializer and the cockpit controller. Specifically, the operation instruction can be received by an LVDS transmitter in the cockpit controller and then transmitted to the SOC in the cockpit controller through, for example, an I2C harness.

[0046] S202, generating a control signal according to a preset encoding rule corresponding to the operation instruction and the preset communication protocol.

[0047] For example, the control signal can be a series of 16-bit hexadecimal codes, which can follow a three-part format of signal ID-signal byte-signal value. Each part can have one or more digits. For example, for a vehicle interior device including a display screen and a background light, the preset encoding rule can be as shown in Table 1 and Table 2.

[0048]

[0049] Table 1: Display screen control signal preset encoding rule

[0050]

[0051] Table 2: Background light control signal preset encoding rule

[0052] ​For example, the control signal can be 0x920001x00, as shown in Table 1 and Table 2, the first segment 0x92 can refer to the signal ID, 0x92 can represent that the control signal is a display screen control signal, the second segment 0001 can refer to the signal byte, 0001 can represent that the signal byte of the control signal is Byte1, that is, the control signal can be used to control the working mode of the display screen, and the third segment 0x00 can refer to the signal value, 0x00 can represent that the control signal is used to control the working mode of the display screen to be in a normal working state.

[0053] The control signal can also be 0x930002x01, as shown in Table 1 and Table 2, the first segment 0x93 can refer to the signal ID, 0x93 can represent that the control signal is a background light control signal, the second segment 0002 can refer to the signal byte, 0002 can represent that the signal byte of the control signal is Byte2, that is, the control signal can be used to control the brightness of the background light, and the third segment 0x01 can refer to the signal value, 0x01 can represent that the control signal is used to control the brightness of the background light to be the brightness corresponding to 0x01.

[0054] Of course, the above content is only an example, and the specific control signal format and the specific preset encoding rule can be adjusted and determined according to the actual situation, and are not limited to the above Table 1, Table 2 and the above example.

[0055] In addition, the in-vehicle equipment is not limited to the background light and the display screen, and can also include an air conditioner, a seat massage, a window mode, etc., which is not limited herein.

[0056] S203, the control signal is sent to at least one in-vehicle equipment corresponding to the control signal through the preset communication protocol to perform corresponding control.

[0057] For example, the control signal is sent to at least one in-vehicle equipment corresponding to the control signal through the preset communication protocol to perform corresponding control, for example, the cockpit controller can send the control signal to the corresponding in-vehicle equipment, such as a display screen or a background light, through a preset communication protocol such as an I2C protocol, and an LVDS deserializer and an MCU. Specifically, the control signal can be sent by the SOC in the cockpit controller to the LVDS transmitter in the cockpit controller through, for example, an I2C harness, and then the control signal is sent to the LVDS deserializer through the LVDS bus by the LVDS transmitter. The LVDS deserializer sends the control signal to the in-vehicle equipment such as the display screen or the background light through a preset communication protocol such as an I2C protocol corresponding to the I2C harness after receiving the control signal.

[0058] It can be understood that the above is only one possible example, and the specific control signal sending process, the specific preset communication protocol type, etc. can be adjusted and determined according to the actual situation, which is not limited here.

[0059] The in-vehicle device control method provided by the embodiment of the application is applied to a cockpit controller. The cockpit controller is connected in communication with a plurality of in-vehicle devices through a preset communication protocol using one bus. The method comprises: receiving an operation instruction obtained based on a user operation; generating a control signal according to a preset encoding rule corresponding to the operation instruction and the preset communication protocol; and sending the control signal to at least one in-vehicle device corresponding to the control signal through the preset communication protocol to perform corresponding control. This method replaces at least two buses and at least two preset communication protocols in the prior art solution with one bus and one corresponding preset communication protocol, so that the cockpit controller can control the plurality of in-vehicle devices through only one bus and one corresponding preset communication protocol, thereby simplifying the hardware structure and software control logic in the in-vehicle device control scheme of the display screen and the background light.

[0060] Optionally, in the embodiment, Figure 2 The plurality of in-vehicle devices can comprise: a background light, at least one display screen; and the control signal can comprise an identifier of a target in-vehicle device.

[0061] The sending of the control signal to at least one in-vehicle device corresponding to the control signal through the preset communication protocol to perform corresponding control can comprise:

[0062] The sending of the control signal to the background light and / or the display screen corresponding to the control signal through the preset communication protocol to make the background light and / or the display screen perform corresponding control.

[0063] For example, the identifier of the in-vehicle device can refer to the Figure 2 For example, the signal ID in Table 1 and Table 2 in the embodiment, such as 0X92 and 0x93, when there are a plurality of display screens, the signal ID can further comprise, for example, 0x94 and 0x95. Of course, in addition to using the signal ID as the identifier of the target in-vehicle device, a text note or the like can also be used as the identifier of the target in-vehicle device. The specific selection and determination can be made according to actual needs, which is not limited here.

[0064] In addition, in the embodiment, when the at least one in-vehicle device corresponding to the control signal comprises the background light, the control signal can comprise an instruction for the background light to operate in a specified mode.

[0065] Exemplarily, the control signal includes an instruction for the background light to operate in the specified mode, for example, the instruction can indicate the background light to Figure 2 When the specified mode further includes other contents, the signal bytes such as Byte3, Byte4, etc. can be further set to indicate the operation of the corresponding other contents, of course, the above-mentioned contents are only possible examples, and how to indicate the background light to operate in the specified mode and which contents the signal bytes such as Byte3, Byte4, etc. correspond to can be adjusted and determined according to actual conditions, which is not limited here.

[0066] Further, on the basis of the above-mentioned embodiments, the multiple modes of the background light can include control of at least one of the background light on / off, color, brightness or different combinations of at least two.

[0067] Exemplarily, the control of at least one of the background light on / off, color, brightness can be as follows Figure 2 As shown in Table 2 of the embodiments, for example, the background light is controlled to be turned off by the control signal 0x930002 0x00, the background light is controlled to be turned on and the brightness is the brightness corresponding to the signal value 0x01 by the control signal 0x930002 0x01, the background light is controlled to be the color corresponding to the signal value 0x00 by the control signal 0x930001 0x00, etc. Optionally, the background light color can also be associated with the theme of the cockpit controller, that is, when the theme of the cockpit controller is set to a first theme, the background light color can be controlled and adjusted to at least one color corresponding to the first theme, and when the theme of the cockpit controller is set to a second theme, the background light color can be controlled and adjusted to at least one color corresponding to the second theme, etc.

[0068] The different combinations of at least two of the background light on / off, color, brightness can be realized by at least two control signals, for example, the background light is controlled to be turned on and the brightness is the brightness corresponding to the signal value 0x01 by the control signal 0x930002 0x01 and the background light is controlled to be the color corresponding to the signal value 0x00 by the control signal 0x930001 0x00, optionally, since the two control signals are both background light control signals and have the same signal ID, they can be combined into a control signal such as 0x930002 0x01 0001 0x00, that is, the control signal can be in the format of signal ID-first signal byte-first signal value-second signal byte-second signal value, and so on. When the control signal is three, four, etc., the combined control signal can be in the format of seven, nine, etc.

[0069] Of course, the above are just possible examples. The specific control of at least one of the following, such as the backlight on / off state, color, and brightness, or different combinations of at least two of them, can be selected and adjusted according to the actual situation, and is not limited to the examples above.

[0070] In addition, based on the above embodiments, when at least one in-vehicle device corresponding to the above control signal includes a display screen, the above control signal includes instructing the display screen to play specified content or operate according to a specified mode.

[0071] For example, the control signal instructing the display screen to play specified content may include, for example, the path to the specified content, and the instruction for the display screen to operate in a specified mode may be, for example, as described above. Figure 2 As shown in Table 2 of the embodiment, the display screen can be controlled to operate in normal working state by, for example, a control signal of 0x92 0001 0x00, or the display screen can be controlled to operate in screen-off state by, for example, a control signal of 0x92 0001 0x01. Of course, if it is necessary to control at least two different combinations of the above display screen operating mode, backlight brightness, etc., at least two control signals or a five-segment format or a seven-segment format control signal composed of at least two control signals can also be used. Of course, how to specifically instruct the above display screen to play specified content or operate in a specified mode can be selected and determined according to the actual situation, and is not limited to the above content.

[0072] Optionally, based on any of the above embodiments, the preset communication protocol can be the integrated circuit bus I2C communication protocol. This I2C communication protocol can adopt a half-duplex synchronous communication mode, which uses fewer pins, has low cost, and is relatively simple to implement.

[0073] Furthermore, based on any of the above embodiments, the bus is a Low Voltage Differential Signaling (LVDS) bus. This LVDS bus can be, for example, a copper PCB trace or a balanced cable, which offers advantages such as low power consumption, low bit error rate, low crosstalk, and low radiation.

[0074] Figure 3 This is a schematic diagram of an in-vehicle equipment control device provided in an embodiment of the present invention. This in-vehicle equipment control device can execute the aforementioned in-vehicle equipment control method. This device can be integrated into devices with computing capabilities, such as the aforementioned cockpit controller. Figure 3 As shown, the device includes:

The method includes: receiving operation instructions obtained based on user operations; generating control signals according to the operation instructions and preset encoding rules corresponding to the preset communication protocol; and sending the control signals to at least one in-vehicle device corresponding to the control signals via the preset communication protocol to execute the corresponding control. This method replaces at least two buses and at least two preset communication protocols in existing technologies with a single bus and a corresponding preset communication protocol. This allows the cockpit controller to control multiple in-vehicle devices using only a single bus and its corresponding preset communication protocol, thereby simplifying the hardware structure and software control logic in in-vehicle device control schemes such as displays and backlights.

[0079] Optionally, the aforementioned multiple in-vehicle devices include: backlighting, at least one display screen; the aforementioned control signals include an identifier of the target in-vehicle device;
