Example Embodiment

[0028] The present invention will be further described below in conjunction with the drawings and embodiments.

[0029] This embodiment proposes an adaptive far and near light switching system, such as figure 1 As shown, it includes an external image processing module 1, a control module 2 and an execution unit 3. The external image processing module 1 is connected to the control module 2 through a CAN bus, and the control module 2 is connected to the execution unit 3 through a CAN bus;

[0030] After the external image processing module 1 obtains the position information of the preceding vehicle through the camera module 4, it obtains the distance information of the preceding vehicle by comparing the light spots of the preceding vehicle with the samples in the memory module 5;

[0031] The external image processing module 1 lights up and adjusts the brightness of the high beams in real time according to the distance information of the vehicle ahead. Since the high beams are not even...

Abstract

The invention discloses a self-adaptive far and near light switching system and a control method thereof and belongs to the field of intelligent control of automotive electronic illumination systems.The self-adaptive far and near light switching system comprises an external image processing module, a control module and an execution unit, wherein the external image processing module is connected with the control module, the control module is connected with the execution unit, the external image processing module is used for acquiring front vehicle information, and the control module is used for receiving a control command of the external image processing module. The execution unit is used for executing the control command sent by the control module. The self-adaptive far and near light switching system optimizes a night illumination effect by continuously and gradually adjusting the brightness of a high-beam lamp, ensures that the brightness of the high-beam lamp does not cause glare of a driver driving a front vehicle and accordingly improves the night driving safety.

Description

technical field [0001] The invention belongs to the field of intelligent control of automotive electronic lighting systems, in particular to an adaptive far and near light switching system and a control method thereof. Background technique [0002] With the rapid development of smart car electronics, headlights are also developing in the direction of intelligence. At present, there are smart car lights such as HSS, AFS, and ADB that are mainstream on the market. Among them, the ADB smart lights are mainly to avoid the dazzling effect of the high beam on the driver in front; the AFS smart lights are mainly based on the steering wheel sensor and the speed information to automatically adjust the direction of the headlights when the vehicle is turning; and the HSS smart lights The car lights mainly realize the automatic switching of high and low light through the rain light sensor and the image processor installed on the front windshield. [0003] As far as the HSS with automa...
