[0042] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0043] Embodiment 1

[0044] like Figure 1 As shown, a vehicle lighting controller mainboard includes: a host 100 and a remote control 200; the host 100 is provided with a power supply module 1, an MCU main control module 2, a wireless receiving module 3, a multi-power output module 4, an indicator light module 5 and a learning button module 6, the wireless receiving module 3, the multi-power output module 4, the indicator light module 5, and the learning button module 6 are respectively connected to the MCU main control module 2, the wireless receiving module 3 is communicatively connected with the remote control 200, and the multi-power output module 4 includes: a multi-channel power output circuit with different levels of current output, the input end of each output circuit is connected to the output end of the MCU main control module 2, and the output end of each power output circuit is connected to an external functional device as an output channel; the external functional device is a low beam headlight, a high beam headlight, a horn, various front-mounted lights and an ambient light, etc.

[0045] The remote controller 200 includes a plurality of transmitting buttons corresponding to the number of power output circuits;

[0046] The learning button module 6 at least includes a learning button 61, which selects the code recording channel by single-clicking the learning button, so that each transmitting button controls one or more output channels of the multi-power output module 4 to output the corresponding function mode by matching the code, and controls the corresponding indicator light of the indicator light module 5. Among them, the MCU main control module 2 is provided with: a function instruction generation unit for analyzing and generating corresponding control instructions according to the corresponding function mode, and a function response unit for responding to the control instruction of the function instruction generation unit to make a function mode. Specifically, the power supply module 1 is used to power the host, and the normal working voltage range is DC11.5V-35V, and the maximum withstand voltage is DC110V; the power supply module 1 is connected to the charging module, and the charging module includes: a charging interface connected to a solar charger / power bank / car charger, and a lithium battery charging management unit that charges the electricity from the charging interface into a built-in lithium battery; the host is also provided with a voltage output by the power supply module 1 to convert the voltage to provide a stable 5V power supply voltage for the MCU main control module 2; the wireless receiving module 3 preferably has a wireless transceiver with a receiving frequency of 433.92MHZ and an open receiving distance of ≥50 meters.

[0047] As mentioned above, this case achieves a high degree of system integration by integrating the power supply module, MCU main control module, wireless receiving module, multi-power output module, indicator light module and learning button module in the host. Through the setting of the multi-power output module, multiple power output circuits with different current levels are provided, so that the multi-power output module can realize multiple functional modes according to the control instructions of the MCU main control module, making the control method more flexible and simple to operate, so as to meet the lighting needs in different driving scenarios, such as overtaking, emergency rescue, daytime driving, etc. Through the learning button module, users can easily pair the transmitting buttons on the remote control to realize the quick call of specific lighting modes. The learning button module adopts intelligent recognition and matching technology, so that each transmitting button on the remote control can be accurately matched with the multi-power output module on the host, which improves the response speed of the system and ensures the accurate transmission of control instructions. Moreover, users can freely set and adjust the lighting mode according to their needs to realize personalized and intelligent lighting control. The MCU main control module performs real-time analysis according to the lighting mode of the indicator light and generates corresponding control instructions to improve the lighting efficiency of the system and reduce unnecessary energy consumption.

[0048] As a specific implementation, the functional mode includes:

[0049] Overtaking function mode, reminding surrounding vehicles through a specific lighting mode;

[0050] Horn function mode, warning through horn sound effects;

[0051] SOS function mode sends out an emergency distress signal through continuous strong light flashing;

[0052] DRL function mode provides continuous and stable light output to improve daytime driving safety;

[0053] The strobe function mode attracts attention through rapid and intense flashing of lights, which is often used for emergency vehicles such as police cars and ambulances;

[0054] The color temperature conversion function mode changes the color temperature of the indicator light by adjusting the current ratio of different power output circuits to adapt to different driving environments and atmospheres.

[0055] As mentioned above, the overtaking function mode reminds surrounding vehicles through a specific lighting mode, so that other drivers can quickly notice the upcoming overtaking action, thereby reducing the risk of traffic accidents caused by lane changes or overtaking. The horn function mode can attract more people's attention in complex environments through horn sound effects, thereby avoiding potential dangers. The SOS function mode sends an emergency distress signal through continuous strong light flashing, which can quickly attract the attention of surrounding vehicles and pedestrians in an emergency and buy precious rescue time for the driver. The DRL function mode can improve daytime driving safety. The flashing function mode can quickly attract the attention of surrounding vehicles and pedestrians, so that the vehicle can maintain high recognition in various environments, which helps to improve driving safety and emergency response efficiency. The color temperature conversion function mode adjusts the current ratio of different power output circuits to achieve the change of indicator light color temperature to adapt to different driving environments and atmospheres, thereby improving the driving experience. For example, in low visibility conditions such as night or foggy days, it can be adjusted to warm colors to enhance the lighting effect; in clear daytime, it can be adjusted to cold colors to improve recognition. To sum up, the overtaking function, horn function, SOS function, DRL function, flashing function and color temperature change function possessed by the vehicle lighting controller motherboard enable one controller motherboard to realize full control of the car's low beam, high beam, horn, etc. It has diverse functions, improves driving safety and driving experience, and can meet the lighting needs in different driving environments and atmospheres.

[0056] like Figure 1 As shown, the host 100 is further provided with a power-on control module 7, and the power-on control module 7 is provided with an ACC input terminal 71 connected to the ACC line of the car, and the power-on control module 7 is used to start normal operation when the car ignition is detected / low power operation when the ACC line is not connected. Specifically, the host can only start working when the car key is turned on, and when the ACC line is not connected, the static current of the entire host is less than 1MA, so as to effectively reduce the static loss of the car battery.

[0057] As shown in the figure, the multi-power output module 4 includes: two power output circuits for outputting 30A current, two power output circuits for outputting 20A current, and two power output circuits for outputting 10A current. Each output circuit is provided with a MOS tube controlled by the MCU main control module 2. In specific implementation, the multi-power output module 4 is composed of circuits such as "QP1-QP8" MOS tubes, and there are 6 independent control channels. In this way, through the above settings, the maximum load capacity of the host in this case is set to: 30A*2; 20A*2; 10A*2, so that the load power is sufficient and large enough. The design of multi-speed current output allows users to choose the appropriate current gear according to actual needs, so as to meet different power needs. Through the 6 independent control channels composed of circuits such as "QP1-QP8" MOS tubes, users can realize independent control of each output circuit, which improves the flexibility and controllability of power output.

[0058] like Figure 1 As shown, the remote controller 200 includes: a wireless touch switch remote controller or a wireless toggle switch remote controller or a wired toggle switch remote controller. In this way, the wireless touch switch remote controller can control the lighting system through a simple touch operation without physically touching the switch, thereby improving the convenience and flexibility of operation. The wired toggle switch remote controller allows the user to switch different lighting modes or functions by toggling the switch, and the operation is intuitive and easy to understand. Although the wired toggle switch remote controller is limited by the length of the cable, in some fixed or limited spaces, the wired toggle switch remote controller may provide a more stable and reliable operating experience. Different types of remote controllers provide a variety of operating methods, allowing users to choose the appropriate control method according to their preferences and habits. Moreover, during the design process, it can be ensured that different types of remote controllers have good compatibility and interoperability with the vehicle lighting controller mainboard, so that users can freely switch different remote controllers to control the same lighting system without worrying about compatibility issues.

[0059] Embodiment 2

[0060] As Figure 2 As shown, a control method for a vehicle lighting controller mainboard, the mainboard includes: a host and a remote controller; including the following steps:

[0061] Connect the power supply to power on the host and remote controller;

[0062] Identify the external voltage input to the host, and if the voltage is greater than a first preset value, start the host normally; in specific implementation, the first preset value is a voltage value greater than the normal working voltage of the host, such as 10V;

[0063] After powering on, perform initialization operation, click the learning button in the learning button module, select the recording channel, and the indicator light of the corresponding channel will light up;

[0064] According to user needs, switch the corresponding function mode through the remote control;

[0065] In the selected lighting mode, according to the received remote control commands, the host generates and responds to corresponding function control commands to control the indicator lights and the corresponding channels to output the corresponding function modes; among which, the function control commands include: overtaking function control commands, horn function control commands, SOS function control commands, DRL function control commands, strobe function control commands and color temperature change function control commands.

[0066] As mentioned above, the control method of this case realizes intelligent power management by identifying the external voltage and judging whether it is turned on normally according to the preset value. By learning the button function, the pairing between the remote control and the host is more flexible and convenient, and the user can choose the recording channel as needed. This method supports a variety of lighting modes, such as overtaking, horn, SOS, DRL, flashing, and color temperature change, so as to enrich the lighting effects of the vehicle. Different lighting modes can be easily switched through the remote control, which is simple and quick to operate and improves the user experience.

[0067] The lighting status of the indicator light directly reflects the currently selected channel and mode, which is convenient for users to confirm and monitor. The control method of this case allows the functions of the vehicle lighting controller to be expanded by adding or modifying functional control instructions, thereby adapting to new lighting scene requirements.

[0068] As a specific implementation, the “after powering on, performing initialization operation, by clicking the learning button in the learning button module, selecting a recording channel, and then the indicator light of the corresponding channel lights up” includes the following steps:

[0069] After powering on, select the code recording channel by clicking the learning button so that the indicator light of the corresponding channel is lit, press one of the buttons on the remote control for T1 seconds, and when the indicator light flashes N times, it means that the code is successfully paired; T1 and N are integers greater than or equal to 3, preferably 3.

[0070] After the code is successfully paired, the remote control can perform the switch function;

[0071] Among them, a button in the remote control can be paired with multiple channels; that is, the pairing principle allows one-to-many; during the pairing process between the remote control and the mainboard, when a button is successfully paired with the corresponding channel, it will enter a "latched" state. This "latched" state means that the controller will remember and fix the corresponding relationship between the button and the channel, and this corresponding relationship will not be lost even after power failure and restart.

[0072] As mentioned above, by clicking the learning button, the user can easily select the recording channel and intuitively confirm the selected channel through the lighting status of the indicator light. The continuous pressing of the remote control button for T1 second and the quick flashing of the indicator light N times as feedback for successful binding are simple and easy to understand. After successful binding, the controller enters the "latch" state to remember and fix the correspondence between the button and the channel, ensuring the continuity of communication between the remote control and the host. One button in the remote control can bind multiple channels, that is, the one-to-many binding principle, allowing users to configure and control the lighting system more flexibly.

[0073] As a specific implementation mode, when the function control instruction of the corresponding function mode is a horn function control instruction, it is switched to a horn switch mode for implementing a horn switch; when the function control instruction of the corresponding function mode is a non-horn function control instruction, it is switched to a common switch mode for implementing a light switch;

[0074] Among them, in the normal switch mode, the remote control button is triggered once to execute the "light on" function, and triggered occasionally to execute the "light off" function; in the speaker mode, use the specific button of the remote control as the activation button, and activate the speaker mode through a specific button combination; when the activation button and the specific button are pressed on the remote control, the corresponding channel of the host is output, and the corresponding channel is disconnected when the button is released. In specific implementation, if the user uses the "No. 1 key" of the remote control as the activation key, and the "No. 2 / 3 / 4 / 5 / 6 keys" are used as feature keys. Press and hold the two buttons "1+2" ​​of the remote control for 3 seconds, and the indicator light changes from constant light to slow flashing and then goes out. At this time, the No. 2 key is converted to the speaker mode inching mode: press and hold the No. 2 button on the remote control, the corresponding channel of the host is output, and release the No. 2 button, the corresponding channel of the host is disconnected; in the speaker mode, only the transmitter 2 / 3 / 4 / 5 / 6 buttons corresponding to the receiver channel can switch the speaker function, and the No. 1 key cannot be switched as a function key; repeat the above operation to restore the "normal switch mode".

[0075] As mentioned above, in the normal switch mode, the "turn on the light" and "turn off the light" functions are respectively executed by single and even triggering of the remote control button. The design is intuitive and easy to understand, and users do not need to remember complex command sequences. In the horn switch mode, it is activated by a specific button combination, and after activation, the horn is controlled by pressing and holding a specific button. The operation is also simple and easy to use. In summary, not only the basic light switch function is realized, but also the horn switch function is introduced, enriching the application scenarios and functionality of the vehicle lighting system. Users can choose to use the normal switch mode or the horn switch mode according to their needs to meet different driving needs.

[0076] like Figure 2 As shown, the control method of this case also includes the following steps:

[0077] When you need to clear the set pairing information, press and hold the learning button for 3 seconds until all channel indicators flash slowly, and continue to press and hold the learning button until the indicator goes out, indicating that all channels have been successfully cleared. In this way, by adding the step of clearing the set pairing information, the method of this case has a reset function, avoids failures caused by misoperation, improves the maintainability of the system, and enhances the user experience.

[0078] As mentioned above, this case protects a vehicle lighting controller mainboard and its control method. All technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
