Intelligent dimming meaus for motor vehicle

Abstract

An intelligent dimming device for motor vehicle is composed of a signal transmitting and receiving circuit A, a single chip control circuit B and an execution circuit. The device is linked with the vehicle dipped headlight, the far-reaching headlamp and width indicator lamp, and is controlled by the vehicle big light dimming switch and the width indicator lamp switch. When two vehicles mounted with the device are encountering at night, only one vehicle open the dipped headlight, the vehicle can transmit dimming signal to another vehicle (the vehicle opens the far-reaching headlamp), and the receiver of the another vehicle can receive the signal in effective distance and change distance light to near light. The dimming process is that: the dipped headlight is opened, and the far-reaching headlamp will quickly reduce brightness and will be gradually extinguished, after several seconds, after the vehicle meeting, the dimmed vehicle will automatically return to distance light. The whole dimming process is natural in vision, and a LED indicating lamp is flashing for indication and is in favor of safe driving. Under special circumstance, for example, the headlight of vehicle is damaged or other reasons; the device can automatically enter dormant state, will not transmit and receive signals to ensure the driving safety.

Description

technical field [0001] The invention relates to a motor vehicle lighting control device, in particular to an intelligent motor vehicle light dimmer. Background technique [0002] Motor vehicle headlights have two illumination functions of high beam and low beam. When a motor vehicle is running normally at night, it is generally illuminated with high beams. When two vehicles meet, in order to prevent the high beams from being dazzled and avoid traffic safety accidents arising therefrom, the Ministry of Communications has stipulated on motor vehicle safety: motor vehicles at night When meeting cars, at a distance of 150M, both sides of the meeting should consciously change the headlights to low beam lighting. Since the change of the far and low beams of the motor vehicle is manually controlled by the driver, due to the driver's negligence and low quality , Malicious opening and other reasons, at present, the safety of motor vehicles at night is not satisfactory, and traffic a...
