The invention belongs to the technical field of vehicle safety, and discloses a device and method for automatically turning on vehicle fog lamps at night in low visibility, comprising: a camera installed in the center of the front windshield of the vehicle, installed in the center of the front bumper of the vehicle and moving toward the vehicle The radar sensor of the direction, the ARM processor installed in the engine compartment of the vehicle, and the electromagnetic switch connected in series on the branch road of the fog lamp; the signal output end of the camera is connected with the first signal input end of the ARM processor, and the signal output of the radar sensor terminal is connected to the second signal input terminal of the ARM processor, the signal output terminal of the ARM processor is connected to the control terminal of the electromagnetic switch, and the output terminal of the electromagnetic switch is connected to the opening branch of the vehicle fog lamp, which has low investment and is suitable for large-scale The characteristics of promotion, intelligence, automation, no operation and high reliability.
Description
technical field [0001] The invention belongs to the technical field of vehicle safety, and in particular relates to a device and method for automatically turning on vehicle fog lamps at night in low visibility. Background technique [0002] The function of fog lights is to make drivers of surrounding vehicles notice the existence of their own vehicle under low visibility conditions, thereby prompting other drivers to take reasonable measures to avoid traffic accidents. All vehicles must be equipped with fog lights, but the actual situation is that many drivers do not know the existence of fog lights at all, or even know but do not know how to turn on fog lights. [0003] From the perspective of fog lamp design, it is only necessary to turn on the fog lamp under low visibility conditions, and it does not need to be turned on under other conditions. Therefore, if it is possible to automatically recognize the visibility of the road ahead at night, a relevant technical solution...
