Night high beam automatic control device and method

Abstract

The invention provides a night high beam automatic control device and method. The night high beam automatic control device comprises a photoresistor sensor, a radar detector, a speed sensor and a single-chip microcomputer. If the photoresistor sensor detects poor ambient illumination outside the vehicle and the radar detector detects that no object exists within a set distance, the single-chip microcomputer controls the high beam to be turned on; if the photoresistor sensor detects poor ambient illumination outside the vehicle and the radar detector detects that an object exists within a set distance, the single-chip microcomputer controls the high beam and the low beam to alternate; the single-chip microcomputer controls the alternating frequency of the high beam and the low beam according to the real speed; according to the night high beam automatic control device and method, alternate flickering control over the high beam and the low beam is achieved, the burden of an automobile driver is relieved through the automatic control device for the high beam at night of the automobile, the feeling adaptability generated by long-term turning on of the high beam of the driver is improved, standardization and reasonability of automobile lamps are guaranteed, and the automobile driving safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automatic control device and method for high beam at night. Background technique [0002] With the development of society and the improvement of people's living standards, cars have become a daily tool in our lives. Safety, as one of the three major issues in the development of automobiles in the world today, is the eternal theme of people driving, especially the safety of driving at night. In reality, it is not uncommon for cars to switch from high beam to low beam in time when driving at night, causing the other driver to be dazzled and causing driving danger, and the phenomenon of irregular use of lights for vehicles is not uncommon. [0003] Zou Zujun et al. designed a set of automatic switching system for high and low beams of automobiles by using ATmega16 single-chip microcomputer, phototransistor, and slope detection sensor. The main function is to automatica...

However, the above research only changes the high beams to low beams when meeting vehicles, and does not change the state of the lights when there are no vehicles meeting or when there are pedestrians ahead.
