[0042] As competition intensifies in the automotive industry, vehicle manufacturers are placing greater emphasis on cost control. As a crucial electronic component, the design of the vehicle lighting control system directly impacts vehicle costs. In related technologies, vehicle lighting control typically involves assigning one or more controllers to each group of lights. For example, the left headlight, right headlight, and main light are controlled by three separate control modules: a left headlight controller, a right headlight controller, and a main light controller. These three modules are connected to the BCM (Body Control Module) via baseline beams. However, this control structure requires a large number of control modules, resulting in a higher overall cost for the lighting control system.

[0043] Therefore, to solve this technical problem, this application proposes a vehicle lighting control module, which can be connected to the vehicle's body controller, the front headlights, and a through light on the same side as the front headlights. The vehicle lighting control module includes a drive control module, a DC-DC module, and a switch module. The DC-DC module is connected to the body controller and can convert the power supply voltage output by the body controller to generate the vehicle lighting operating voltage. The switch module is connected to the DC-DC module, the front headlights, and the through light, and can be used to control the connection between the front headlights and / or the through light and the DC-DC module. The drive control module is connected to the body controller, the DC-DC module, and the switch module, and can receive control signals output by the body controller and generate drive signals to the DC-DC module according to a preset driver program, so that the DC-DC module can perform voltage conversion according to the drive signals. The drive control module is also used to control the switch module according to the control signals.

[0044] This application adopts the structure of the above-mentioned vehicle lighting control module. Through the integrated design of the control module and the switch module, a single drive control module can control both the front headlights and the through lights. This eliminates the need to configure a separate control module for each type of vehicle light, reducing the number of control modules required for the vehicle lighting control system and directly lowering hardware costs.

[0045] The following will be explained and described through several embodiments.

[0046] Please see Figure 1 , Figure 1 This is a structural schematic diagram of Embodiment 1 of the vehicle lighting control module of this application.

[0047] In this embodiment, the vehicle lighting control module may include a drive control module, a DC-DC module, and a switch module.

[0048] The DC-DC module is connected to the body controller and is used to convert the power supply voltage output by the body controller to generate the operating voltage of the headlights.

[0049] The switch module is connected to the DC-DC module, the front headlights and the through light respectively, and is used to control the connection between the front headlights and / or the through light and the DC-DC module;

[0050] The drive control module is connected to the body controller, the DC-DC module and the switch module respectively. It is used to receive the control signals output by the body controller and generate drive signals to the DC-DC module according to the preset driver program, so that the DC-DC module performs voltage conversion according to the drive signals. The drive control module is also used to control the switch module according to the control signals.

[0051] Specifically, the body controller is the vehicle's main control unit. It connects to the headlight control module via a power supply line (with an input voltage of 9-16V and a maximum current of 10A) to provide operating power. Simultaneously, the body controller can also output corresponding control signals based on the user's driving behavior to control various vehicle components. For example... Figure 1As shown, the body controller is connected to the DC-DC module. The body controller provides a constant supply voltage, while the DC-DC module is mainly used for voltage conversion, transforming the supply voltage output by the body controller into a suitable operating voltage for the front headlights and through-lights (different headlights may have different operating voltage requirements) to ensure stable and normal operation of the headlights. The DC-DC module generally uses switching power supply (SFC) technology. A switching power supply controls the output voltage by switching current rapidly (e.g., using a transistor) at high speed. The switching power supply adjusts the voltage by controlling the ratio of on and off times (i.e., pulse width modulation, PWM). Therefore, the DC-DC module can also be connected to the drive control module. Through its connection to the body controller, the drive control module can receive control signals from the user for the headlights. The drive control module has a preset driver program that can generate drive signals (e.g., PWM duty cycle signals) based on the control signals and send them to the DC-DC module. The DC-DC module then performs voltage conversion based on the drive signals to obtain the operating voltage suitable for the front headlights and through-lights.

[0052] The switch module is connected to the DC-DC module, the front headlights, and the through light on the same side as the front headlights (hereinafter referred to as the same-side through light); that is, the switch module is connected to the DC-DC module, the front left headlight, and the left through light, or the switch module is connected to the DC-DC module, the front right headlight, and the right through light. The switch module is responsible for controlling the connection between the DC-DC module and the front headlights and the same-side through light. The switch module is also connected to the drive control module. After receiving the control signal for the vehicle lights from the body controller, the drive control module can control the switch module to turn on or off, thereby determining whether the front headlights and / or the same-side through light are connected to the DC-DC module, and realizing the lighting control of the front headlights and the same-side through light.

[0053] In one feasible implementation, the front headlights may include a daytime running light module and a turn signal module; the switch module may include a first switch device, a second switch device and a third switch device to achieve targeted control of different headlight modules; Figure 2 This is a detailed structural diagram of the vehicle lighting control module.

[0054] like Figure 2As shown, the first switching device is connected to the drive control module, the DC-DC module, and the daytime running light module; the second switching device is connected to the drive control module, the DC-DC module, and the turn signal module; and the third switching device is connected to the drive control module, the DC-DC module, and the through light module. Specifically, the first switching device controls the connection between the daytime running light module and the DC-DC module, the second switching device controls the connection between the turn signal module and the DC-DC module, and the third switching device controls the connection between the through light module on the same side and the DC-DC module. All three switching devices are connected to the drive control module and can control the corresponding vehicle light module according to the control signal. The first, second, and third switching devices are all components with switching functions. In some feasible embodiments, the first, second, and third switching devices can be field-effect transistors (FETs), which are nanosecond-level switching devices that can achieve rapid control and meet the timeliness requirements of vehicle light control.

[0055] The aforementioned front headlights and continuous lights can both be LED arrays. LED arrays offer more uniform brightness and achieve better lighting effects. For example... Figure 2 As shown, both the daytime running light module and the turn signal module can be 6×4 LED arrays; the through light is a 6×5 LED array. Each LED in the LED array is relatively independent, so even if an individual LED fails, it will not affect the normal operation of the entire lighting system, improving the reliability and durability of the vehicle lighting system and reducing maintenance costs caused by the failure of a single LED.

[0056] In addition, such as Figure 2 As shown, the DC-DC module can specifically include a boost circuit, a first buck circuit, and a second buck circuit. The boost circuit is connected to the body controller and the drive control module, respectively, to boost the supply voltage. The first buck circuit is connected to the boost circuit, a first switching device, and a second switching device, respectively, to buck the boosted voltage to generate the first headlight operating voltage. The second buck circuit is connected to the boost circuit and a third switching device, respectively, to buck the boosted voltage to generate the second headlight operating voltage.

[0057] The aforementioned DC-DC module includes a boost circuit and two buck circuits. The boost circuit boosts the power supply voltage from the body controller, and the boosted voltage is then processed by the first and second buck circuits to obtain the first headlight operating voltage and the second headlight operating voltage for the same-side continuous light. In other words, the front headlights and continuous light each have their own buck circuit, enabling precise voltage control of different types of lights without mutual interference, resulting in higher stability of the headlight control. Figure 2 As shown, the vehicle lighting control module can also be equipped with a first input port module, through which the power supply line can be connected to the boost circuit to provide a constant power supply voltage.

[0058] The vehicle lighting control module may also include a first signal input line, a second signal input line, and a third signal input line; such as Figure 2 As shown, the first signal input line is connected to both the body controller and the drive control module, and is used to receive the position light control signal output by the body controller. The drive control module can control the first switching device to turn on, the second switching device to turn off, and the third switching device to turn on according to the position light control signal. The second signal input line is connected to both the body controller and the drive control module, and is used to receive the daytime running light control signal output by the body controller. The drive control module is also used to control the first switching device to turn on, the second switching device to turn off, and the third switching device to turn off according to the daytime running light control signal. The third signal input line is connected to both the body controller and the drive control module, and is used to receive the turn signal control signal output by the body controller. The drive control module is also used to control the first switching device to turn off, the second switching device to turn on, and the third switching device to turn off according to the turn signal control signal.

[0059] The three signal input lines (CLL, DRL, and TURN) can respectively receive the position light control signal, daytime running light control signal, and turn signal control signal from the body controller; for example... Figure 2 As shown, the headlight control module also has a second input port module. The first signal input line, the second signal input line, and the third signal input line can be connected to the drive control module through this second input port module. Each signal is transmitted using an independent signal line, achieving physical isolation between different signals and avoiding signal crosstalk. After receiving the high-level position light control signal from the CLL input, the drive control module can control the operation of the boost circuit, the first buck circuit, and the second buck circuit, and control the first switching device to turn on, the second switching device to turn off, and the third switching device to turn on, so as to illuminate the daytime running light module of the front side headlight (e.g., Figure 2 (6×4 LED array) and through lights on the same side (such as) Figure 2 The 6×5 LED array shown enables vehicle position light control; after receiving a high-level daytime running light control signal from the DRL input, the drive control module can control the operation of the boost circuit and the first buck circuit, and control the first switching device to turn on, the second switching device to turn off, and the third switching device to turn off, so as to illuminate the daytime running light module of the front side headlights (such as...). Figure 2The 6×4 LED array shown enables daytime running light control. Upon receiving a high-level turn signal input from the TURN input, the drive control module controls the operation of the boost circuit and the first buck circuit, and controls the first switching device to turn off, the second switching device to turn on, and the third switching device to turn off, thereby illuminating the turn signal module of the front side headlights (such as...). Figure 2 The 6×4 LED array shown enables turn signal control. Furthermore, the headlight control module can be configured with a feedback module, which connects to both the drive control module and the body controller. This feedback module can relay the turn signal control results to the body controller via a turn-feedback line (TURN-FB), allowing the user to promptly receive the headlight control information.

[0060] It is worth mentioning that the aforementioned headlight control module may also include a filtering module. This filtering module is connected to the switching module, the front headlights, and the through-lights, respectively. It can suppress noise interference to stabilize the headlight operating voltage output by the DC-DC module. On the one hand, the filtering module can filter out switching noise from the step-down circuit; on the other hand, it can block high-frequency noise, reducing the risk of electromagnetic interference to the entire vehicle. Figure 2 As shown, the filtering module may include three filtering components: the first filtering component is connected to the first switching device and the daytime running light module of the front headlight; the second filtering component is connected to the second switching device and the turn signal module of the front headlight; and the third filtering component is connected to the third switching device and the through light on the same side.

[0061] It is easy to understand that the vehicle lighting control module provided in this application embodiment can achieve the control of the front headlight and the through light on the same side by a single drive control module through the integrated design of the drive control module and the switch module. This eliminates the need to configure a separate control module for each type of vehicle light, reduces the number of control modules used in the vehicle lighting control system, and directly reduces the hardware cost of the vehicle lighting control system.

[0062] Furthermore, this application also proposes a vehicle lighting control system, which may include a body controller, headlights, a continuous light, and a vehicle lighting control module as described above.

Since the vehicle lighting control system of this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0063] In one feasible implementation, the number of vehicle lighting control modules is 2; the front headlights may include a front left headlight and a front right headlight; the through light includes a first through light on the same side as the front left headlight and a second through light on the same side as the front right headlight; Figure 3 Here is a schematic diagram of an example vehicle lighting control system, such as... Figure 3As shown, the first headlight control module is connected to the body controller, the front left headlight and the first through light, and can be used to control the left headlight (i.e., the front left headlight and the left through light on the same side); the second headlight control module is connected to the body controller, the front right headlight and the second through light, and is used to control the right headlight (i.e., the front right headlight and the right through light on the same side).

[0064] The aforementioned front left headlight and front right headlight both include a daytime running light module and a turn signal module; wherein, the daytime running light module can be a 6×4 LED array; the turn signal module can be a 6×4 LED array; the first through light and the second through light are both 6×5 LED arrays; for details, please refer to the description in the aforementioned embodiment section, which will not be repeated here.
