Abstract

The invention provides a Bluetooth technology based automobile high beam and low beam automatic control system and belongs to the technical field of automobile lamps. Through the Bluetooth technology based automobile high beam and low beam automatic control system, the problem of how to accurately and efficiently realize automatic switching on a high beam and a low beam in the automobile driving process is solved. The automatic control system comprises a light intensity detection circuit, a Bluetooth transmission module, a single-chip microcomputer control circuit and a high-power constant current driving circuit which are connected in sequence. The single-chip microcomputer control circuit makes a judgment according to a detected cab light intensity signal of the Bluetooth transmission module, controls the high-power constant current driving circuit to operate to drive a load to conduct lighting when the ambient light is less than a set value, judges the condition of automobile meeting according to the light intensity change rate when high beams are turned on, gives a load high beam and low beam switching flickering prompt when it is judged that the high beams of an opposite automobile are turned on and controls the high beams to be switched to low beams after the prompt. The Bluetooth technology based automobile high beam and low beam automatic control system can efficiently and accurately judge the ambient light intensity and accurately and efficiently control the high beams and the low beams to be automatically switched to conform to the driving environment according to the ambient light change of a cab.

Description

technical field [0001] The invention belongs to the technical field of automobile lights, and relates to an automatic control system for far and low beams of automobiles based on bluetooth technology. Background technique [0002] With the continuous rapid development of China's economy, the use of automobiles in people's daily life is becoming more and more common, and China's automobile industry continues to grow, showing a momentum of vigorous development.
