Automatic switching method of vehicle high beam and low beam based on intelligent identification of multi-road conditions

Abstract

The invention discloses an automatic switching method of a vehicle high beam and a low beam based on the intelligent identification of multi-road conditions, which comprises the following steps: afterthe high beam lamp is turned on, the road condition identification is carried out when the driver is judged not to intervene manually; When a special section of road appears, the light flashes far and near until the end of the special section of road; Measure the distance between the vehicle and the meeting vehicle. When the distance is less than 150m, the high beam is switched to the low beam until the meeting vehicle is finished. The invention provides an automatic switching method of vehicle high-low beam lamp based on intelligent identification of multi-road conditions, which can switch lights according to specific road conditions when a driver forgets to switch lights, and improves driving safety.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a method for automatically switching high and low beams of cars based on intelligent identification of multiple road conditions. Background technique [0002] Automobiles expand the radius of people's daily life and speed up the transportation of goods. The impact on life has both positive and negative sides. It can improve the quality of life, make holiday travel more convenient, and provide the possibility for fast transportation. But it will also cause environmental pollution and various traffic accidents. [0003] Among them, the non-standard use of car lights can also cause major accidents. The low beam is used for close-range lighting, with a large irradiation range (about 160 degrees), a short irradiation distance, and the degree of concentration cannot be adjusted; while the light emitted by the high beam will be emitted in parallel, the light is more concentrated, the bright...

AI Technical Summary

Problems solved by technology

The traditional method adopts the form of manual control by the driver, but because some drivers are negligent or lack safety common sense, and some drivers have limited driving skills, manual alternate operation is extremely easy to cause traffic accidents

Although the relevant staff have conducted some research on the above problems, the research direction is often only for a certain point, the direction is relatively single, and it is relatively scattered, and it is not integrated into a coordinated whole
