Positioning-based automatic switching control system for high beams and low beams of vehicle

Abstract

The invention discloses a positioning-based automatic switching control system for high beams and low beams of a vehicle. The system comprises a GPS positioning module, a storage module, a vehicle speed sensing module, an analog-to-digital conversion module, a signal acquisition module, a control module and a light switching module. The GPS positioning module is used for obtaining position coordinates through real time positioning; the storage module is used for prestoring road position coordinates; the vehicle speed sensing module is used for acquiring current driving speed of the vehicle to obtain analog signals and obtaining digital signals by converting the analog signals with the analog-to-digital conversion module; the control module is used for obtaining current driving speed of the vehicle and by comparing the prestored road position coordinates, when the vehicle is driven within the prestored road, generating and outputting control signals; the light switching module is used for controlling the switching between high beams and low beams according to the control signals. By means of the system, automatic switching is carried out between the high beams and low beams so as to increase the automation degree of the system.

Description

Technical field [0001] The invention relates to a positioning-based automatic switching control system for vehicle long and short beams, which belongs to the technical field of vehicle-mounted equipment. Background technique [0002] The high beam of the car is designed to allow the driver to see the far road conditions clearly at night when driving at high speed, but if you do not switch to the low beam in time when meeting cars, its strong light will make the opposite vehicle unable to see the road clearly, and traffic accidents are very likely to occur . According to domestic statistics, accidents related to high beams account for 30 to 40% of traffic accidents that occur at night, and this is an upward trend. [0003] Regarding the use of high-beam headlights when driving at night, the "Road Traffic Safety Law of the People's Republic of China" has made clear regulations, but in actual driving, it is very serious that the high beams are turned off when meeting cars and passing...
