Intelligent car light control method based on cloud computing

Abstract

The invention provides an intelligent car light control method based on cloud computing. The method comprises the steps: establishing car light control modes; transmitting car speed and car concrete position coordinates detected by a vehicle-mounted navigator to a cloud server by virtue of a GPS (global positioning system) in real time; determining which kind of section of a highway where the car is positioned by matching the car position coordinates with a cloud map by the cloud server, and calculating road condition information in next set time period according to the car speed; determining one car light control mode according to the road condition information and the type of the section of the highway in the next set time period, and controlling the lighting direction of a car light in real time. According to the scheme, first of all the comprehensively concrete car light control modes are established, the types of the section of the highway where the car is positioned is determined by matching the car coordinates and the cloud map by the cloud server, and the road condition information of the next section of the high way is calculated in advance, so the lighting mode of the car light can be adjusted in advance and in time; based on the cloud computing, the response speed is high, and the timeliness is high; meanwhile, the car light control modes are set according to the types of the section of the highway and the road condition information, and lighting requirements of various road conditions can be met.

Description

technical field [0001] The invention relates to a cloud computing-based intelligent vehicle lamp control method. It belongs to the technical field of vehicle lighting. Background technique [0002] At present, most car lights are fixed relative to the car body, and cannot automatically adjust the lighting direction as the car turns. When turning at night, the blind spot on the inside of the curve is likely to cause safety accidents; The light is dark and the headlights are on, but when the car passes by, it will forget to turn off the headlights. Such problems often occur. Investigations show that insufficient lighting conditions or unreasonable lighting directions of automobile lights are one of the important reasons for nighttime traffic accidents. [0003] The existing adaptive front-lighting control system AFS (Adaptive Front-lighting System, AFS) consists of four parts: sensor, ECU, light control system and headlights. The vehicle speed sensor and the steering wheel ...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the intelligent vehicle light control method has obvious hysteresis, slow calculation speed, poor timeliness, and single illumination mode, thereby proposing a fast response and high timeliness based on cloud storage and calculation. , all-round, intelligent car light control mode that adapts to various road conditions
