[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0039] As described in the background art, the basic principle of the adaptive headlight system of an automobile is to collect the dynamic signal parameters of the automobile through sensors such as vehicle speed, attitude, corner, and position installed on the vehicle, and then generate a control signal through the analysis, judgment, and algorithm operation of the headlight main controller, control the motor drive controller to output a corresponding drive signal to the actuator, and finally the actuator controls the headlight to perform corresponding operations to complete the working process of the adaptive headlight system. The automotive AFS is the main development direction of the future automotive front lighting system.

[0040] However, in the existing adaptive headlight system, the sensor, the headlight main controller, and the motor drive controller are respectively independently arranged at different positions of the headlight system. The sensor and the motor drive controller are respectively connected to the headlight main controller through their respective external transmission harnesses. When the external transmission harness connects components, not only is it easy to have connection failures, but also the length of the external transmission harness is long. When the external transmission harness connects components, it will pass by or be close to different electrical components inside the vehicle body, making the external transmission harness vulnerable to electromagnetic interference from the external environment and causing problems such as signal loss, and ultimately resulting in the failure of the adaptive headlight system.

[0041] Based on this, the embodiments of the present application provide an adaptive headlight system and a vehicle, which effectively solve the existing technical problems, improve the problem that the data transmission between the sensor and the motor drive controller and the headlight main controller is greatly affected by the environment, and make the interference electromotive forces generated by the sensor, the headlight main controller, and the motor drive controller basically the same, which is convenient for the implementation of the protection strategy.

Therefore, there is no need to connect the sensor 200 and the motor drive controller 400 to the headlight main controller 300 respectively through an external transmission harness. This not only avoids the problems caused by connection failures of the external transmission harness, but also avoids the problem of signal transmission loss caused by the external transmission harness being easily affected by electromagnetic interference in the external environment, and improves the problem that the data transmission between the sensor 200 and the motor drive controller 400 and the headlight main controller 300 is greatly affected by the environment. Moreover, since the sensor 200, the headlight main controller 300, and the motor drive controller 400 are integrated on the same circuit board 100, their positions are close to each other, thus ensuring the consistency of the ground wire impedance. Therefore, when the circuit board 100 is affected by external electromagnetic interference, the interference electromotive forces generated by the sensor 200, the headlight main controller 300, and the motor drive controller 400 can be basically the same, which not only facilitates the implementation of the protection strategy, but also improves the stability of the adaptive headlight system. In addition, integrating the sensor 200, the headlight main controller 300, and the motor drive controller 400 on the same circuit board 100 also reduces the manufacturing cost of the adaptive headlight system and is more convenient for assembly and production.
