Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] As described in the background, with the development of modern industry, the automobile technology has achieved a leap-forward rapid development. And with the development of economy, the demand for automobiles in modern life is getting larger and larger, and the performance and humanized design of automobiles are also getting more and more attention. The lighting lamps on the automobile, especially the front and rear lamps on the automobile, are very important for road driving safety, and have a major role in indicating the following vehicles and pedestrians. The lighting control process of the lamps of the vehicle is usually that the vehicle body outputs a lighting signal to the driving device of the lamps, and then the driving device outputs a corresponding driving signal to the lamps to control the lighting of the lamps. For the lamps of the same vehicle model, the lighting and light emitting requirements of different markets are different, such as the requirements of the light emitting area of the lamps in the American market and the European market are different. Therefore, the driving signals connected by the lamps in different markets are different, so that the driving devices used in different markets are different, which finally leads to the reducibility of the parts of the vehicle.

[0040] Based on this, the embodiments of the present application provide a driving circuit board, a driving device and a vehicle, which effectively solve the existing technical problems, use the same driving circuit board to achieve the lighting effects of different types of lamps, and improve the replaceability of vehicle parts.

[0041] To achieve the above purpose, the technical solutions provided in the embodiments of the present application are as follows, specifically combined with Figures 1 to 10 The technical solutions provided in the embodiments of the present application are described in detail.

[0042] refer to Figure 1 As shown, it is a structural schematic diagram of a driving circuit board provided in an embodiment of the present application, wherein the driving circuit board 10 is used to drive the lamp 20, and the driving circuit board 10 includes: an opening port 101, the opening port 101 is electrically connected to the control port 31 of the control component 30, and the control port 31 outputs a lighting start signal, and the lighting start signal is used to control the driving circuit board 10 to access the feedback signal; a sampling port 102, the sampling port 102 is electrically connected to the feedback port 21 of the lamp 20, and the feedback port 21 outputs the feedback signal, and the feedback signal carries the target driving signal required for the current type of the lamp 20 to be lit; a driving port 103, the driving port 103 is electrically connected to the power port 22 of the lamp 20, and the driving port 103 outputs the target driving signal, and the lamp 20 lights up in response to the target driving signal.

[0043] It is understandable that the technical solution provided by the embodiment of the present application is that the feedback signal output by the lamp 20 carries the target drive signal required for the current type of lamp 20 to be illuminated. In other words, for the same vehicle model, the lamp 20 on the vehicle feedbacks the target drive signal corresponding to the lamp 20 in the corresponding market, such as the target drive signal corresponding to the lamp 20 in the European market or the target drive signal corresponding to the lamp 20 in the US market. The driver circuit board 10 then analyzes and processes the feedback signal and outputs the target drive signal corresponding to the type of lamp 20. Therefore, whether it is the US market, the European market, or other markets, the same driver circuit board can be used to achieve the lighting effect of different types of lamps 20, ultimately improving the replaceability of vehicle parts.

[0044] like Figure 2, which is a schematic diagram of the structure of another driver circuit board provided in an embodiment of the present application, wherein the driver circuit board 10 provided in an embodiment of the present application includes a processor 110, a sampling circuit 120, and a power supply circuit 130.

The lighting-on signal is used to control the processor 110 to find a target driving signal corresponding to the sampling signal from the memory 140, and control the processor 110 to generate the lighting control signal. The processor 110 uses a lookup table to obtain the driving signal corresponding to the sampling signal, which can not only improve the processing speed of the processor 110, but also reduce the operation energy consumption of the processor 110, thereby improving the performance of the driving circuit board. In some embodiments, the memory 140 can store mapping data of sampling signals and driving signals corresponding to lamps 20 in the American market and mapping data of sampling signals and driving signals corresponding to lamps 20 in the European market; after obtaining the sampling signal, the processor 110 can determine whether the lamp 20 belongs to the American market or the European market according to the sampling signal, and also obtain the driving signal required for driving the lamp 20 in the corresponding market and other related information.
