Intelligent control method for high beam lights and low beam lights of a vehicle on basis of internet of vehicles

Abstract

The invention relates to an intelligent control method for high beam lights and low beam lights of a vehicle on the basis of the internet of vehicles. The method comprises the steps that 1, the specific location of a key node is found on an in-vehicle map, and a target field is drawn by taking the key node as the center a circle and taking the running required distance as a radius; 2, when the vehicle makes contact with the boundary of the target field, corresponding control operations of the high beam lights and the low beam lights of the vehicle are performed; 3, when other vehicles appear in the target filed, corresponding control operations of the high beam lights and the low beam lights of the vehicle are performed; 4, the external light intensity, temperature and relative humidity orwireless signals of the vehicle are collected and compared with corresponding threshold values, and corresponding control operations of the high beam lights and the low beam lights of the vehicle areperformed. Accordingly, intelligent comprehensive control over the high beam lights and the low beam lights can be effectively and accurately achieved, the system load is small, operation is stable,and the safety is high.

Description

technical field [0001] The invention relates to the field of intelligent vehicles, in particular to an intelligent control method for high and low beams of vehicles based on the Internet of Vehicles. Background technique [0002] At present, the Internet of Things technology has developed rapidly, and the Internet of Vehicles technology is the specific application of the Internet of Things technology in the field of intelligent transportation. The car networking vehicle system regards the vehicle as the control object, and at the same time regards the vehicle as an information node. Through each vehicle in the system, it senses and collects the driving environment information, uses wireless communication technology to realize information sharing, and conducts large-scale intelligent unified management of vehicles. It provides users with services such as real-time and accurate information query, route navigation, accident diagnosis, leisure and entertainment, etc., which can ...

Problems solved by technology

And when the vehicle turns on the high beam, if the pedestrian is about 15 meters away from the front of the vehicle, the figure of the pedestrian will be completely engulfed by the light, and the driver will not be able to see the pedestrian.

In addition, if a vehicle at a short distance behind turns on the high beam, a large area of ​​halo will appear in the three rearview mirrors inside and outside the front vehicle, which will reduce the visible range of the road ahead of the vehicle behind and greatly affect driving safety.

And when encountering low-visibility road environments such as fog, rain, snow, sand and dust, as well as entering tunnels and driving environments where the external light intensity is too low when there are no street lights, due to unreasonable use of low beams and high beams. The situation that leads to driving accidents; therefore, if the use of high and low beams cannot be reasonably used, it will seriously reduce the driving safety at night and greatly increase the probability of dangerous accidents
