[0033] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] In the prior art, the road conditions collected by the CCD are collected by the body control system ECU, and then the collected information is sent to the headlight control module after processing. However, due to the development of new energy and the increasing intelligence of automobiles, the resource allocation requirements of the body control module are also increasing. In order to reduce the burden of the body control module and reduce the allocation of body module resources. Integrating CCD in the headlight module, compared with the traditional ADB headlight electronic control device, there is no need for the body control system ECU to control the headlights, reducing the connection harness between the body controller and the lamps, and enhancing the anti-interference ability of the headlights.

[0035] In order to fill the shortcomings of the ADB headlight module solution in the field of LED automobile modules, the utility model provides an intelligent automobile lamp anti-interference design device, such as Figure 1 As shown, it includes a CCD camera detection module 1, a SOC module 2, a DC-DC module 3, a CAN transceiver 4 and an ADB module 5;

[0036] The SOC module 2 establishes communication connections with the CCD camera detection module 1 and the CAN transceiver 4 respectively through the CAN connection port;

[0037] The DC-DC module 3 establishes a communication connection with the SOC module 2 via an I2C connection port or an SPI connection port;

[0038] The ADB module 5 is connected to the CAN transceiver 4 and the DC-DC module 3 respectively.

[0039] Exemplarily, the SOC module 2 is connected to the CCD camera detection module 1 and the CAN transceiver 4 through the CAN connection port to achieve intercommunication. The SOC module 2 is then connected to the DC-DC module 3 through the I2C connection port or the SPI connection port to transmit information.

[0040] In one embodiment, the CCD camera detection module 1 is used to collect image information of the environment around the car and send the image information to the SOC module 2; the image information includes road information of the environment around the car.

[0041] Exemplarily, the CCD camera detection module 1 is used to collect road information in front of the car, such as pedestrians, light intensity, etc. Then, the image collected from the surrounding environment of the car is sent to the SOC module 2. Specifically, the SOC module 2 is a SOC system chip.

[0042] In one embodiment, the SOC module 2 includes a receiving unit, a converting unit and a sending unit;

[0043] The receiving unit is used to obtain the road information collected by the CCD camera detection module 1;

[0044] The conversion unit is used to quantize and decode the road information to convert the road information into digital information;

[0045] The sending unit is used to generate a control command according to the digital information, and send the control command to the CAN transceiver 4 and the DC-DC module 3 through the CAN connection port.

[0046] Exemplarily, the SOC system chip quantizes and decodes the collected image information to complete the radio and television conversion. The SOC system chip then processes and analyzes the photoelectric signal and sends control instructions to the CAN transceiver 4 and the DC-DC module 3.

[0047] Specifically, the SOC system chip obtains the road information collected by the CCD camera detection module 1, and converts the road information into digital information, and further generates a control command from the digital information and sends it to the CAN transceiver 4 through the CAN connection port.

[0048] In one embodiment, the CAN transceiver 4 is used to convert the control instruction from a TTL signal into a differential signal of a CAN bus and send it to the ADB module 5 .

[0049] In one embodiment, the ADB module 5 is used to control the high and low beam LED lights according to the control instructions.

[0050] Exemplarily, the CAN transceiver 4 converts the CAN signal sent by the SOC system chip to the ADB module 5 to automatically adjust the brightness and lighting position of the LED, and adjust the distance, nearness, brightness and darkness of the LED lighting.

[0051] Specifically, the CAN transceiver 4 converts the TTL signal of the CAN controller into a differential signal of the CAN bus and sends it to the ADB module 5. The ADB module 5 automatically controls the high and low beam LED lights according to the control command generated by the controller.

[0052] In one embodiment, the ADB module 5 is further configured to feed back target information to the SOC module 2 after executing the control instruction.

[0053] In one embodiment, the SOC module 2 is further configured to send the target information to the DC-DC module 3 to adjust the target voltage required by the ADB module 5 .

[0054] Exemplarily, the SOC system chip receives the image information collected by the CCD camera detection module 1, processes it into a digital signal and issues a control instruction. The ADB module 5 executes the instruction and then feeds back to the SOC system chip. The SOC system chip transmits the feedback target information to the DC-DC module 3 to adjust the voltage required by the ABD module 5.

[0055] In one embodiment, the ADB module 5 is provided with an LED driving controller, so as to control the turning on and off of a single LED through the LED driving controller.

[0056] In one embodiment, the number of the LEDs does not exceed 100, and the multiple LEDs are arranged in a matrix module.

[0057] For example, the LED driving controller is innovatively designed in the ADB module 5, and a matrix control method is adopted to realize 100% single on and off control of less than 100 LEDs, and realize pixel adjustment from 1% to 100%, and a matrix layout composed of multiple LEDs.

[0058] In one embodiment, the DC-DC module 3 includes a DC-DC Boost unit and a DC-DC BUCK unit;

[0059] The DC-DC Boost unit is used to increase the power supply voltage to the voltage required by the ADB module 5;

[0060] The DC-DC BUCK unit is used to step down the voltage boosted by the DC-DC Boost unit to the voltage required by the ADB module 5 when at least one LED in the LED matrix module is turned off.

[0061] Exemplarily, the DC-DC module 3 provides the voltage required by the ADB module 5. When the LED matrix module in the ADB module 5 changes, the SOC system chip will control the DC-DC module 3 to adjust the output voltage required to ensure the output efficiency. The DC-DCBoost unit boosts the power supply voltage to the voltage required by the ADB module 5. When the LED matrix module in the ADB module 5 changes (for example, turning off one or several LEDs), the DC-DCBUCK unit steps down the voltage boosted by the DC-DCBoost unit to the voltage required by the ADB module 5.

[0062] In a specific embodiment, after the CCD camera detection module 1 completes collecting the road information, it directly sends it to the ADB module 5, which automatically identifies and controls the high and low beams of the vehicle, without going through the vehicle body control system.

[0063] In summary, compared with the traditional ADB solution, Figure 2As shown, the body control unit ECU collects information from the ADAS module and sends the processed road condition information to the MCU controller. The MCU analyzes the information and issues control instructions to control the DC-DC and ADB modules to automatically adjust the high and low beam lights, prevent passers-by from dizziness, etc. In the utility model, the SOC module will directly receive the information from the CCD camera detection module and the acquisition module, and the SOC module will process and identify the image, complete the photoelectric conversion and control the DC-DC module and the ADB module. It can be seen that the utility model can integrate the information processing and CCD camera detection modules in the headlight module, without the need for body control system connection, reduce the connection harness between the body controller and the lamp, reduce the allocation of resources on the body control module, and enhance the anti-interference ability of the headlight.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
