Automatic vehicle headlight control system based on vehicle-infrastructure integration

Abstract

The invention discloses an automatic vehicle headlight control system based on vehicle-infrastructure integration. The automatic vehicle headlight control system comprises on-board equipment and roadside equipment which are connected with each other through a wireless communication module implemented through an RF (radio frequency) technology. A vehicle positioning module is used for acquiring vehicle position signals in real time and transmitting the signals to the roadside equipment through the wireless communication module, and a central processing unit in the roadside equipment is used for comparing the vehicle position signals with prearranged light-switching position signals, outputting the light-switching signals when a vehicle reaches a light-switching position, and transmitting the light-switching signals to the on-board equipment through the wireless communication module so as to control a signal execution module to switch lamplight. By the automatic vehicle headlight control system, a vehicle can switch between high beam and low beam alternately timely to hint when passing by road segments such as pedestrian crosswalks, ramps and sharp turns at night and is capable of turning on a dipped headlight for lighting in the daytime before entering a tunnel.

Description

technical field [0001] The invention relates to the field of vehicle-road coordination, in particular to the field of automatic control of automobile headlights combined with vehicle-road coordination technology. Background technique [0002] With the development of my country's economy and science and technology, the number of cars is increasing, and the safety of cars is getting more and more attention. According to regulations, when a car passes through sharp bends, slopes, crosswalks and other road sections at night, it should alternately use high and low beams to signal. Nowadays, most vehicles switch between high and low beams manually. Drivers sometimes forget to alternate between high and low beams, and at the same time drivers alternate manually. It will also affect the safe driving of vehicles and easily cause traffic accidents. In addition, when a vehicle enters a tunnel during the day, the ambient light suddenly changes from bright to dark, causing temporary bli...

Problems solved by technology

According to regulations, when a car passes through sharp bends, slopes, crosswalks and other road sections at night, it should alternately use high and low beams to signal. Nowadays, most vehicles switch between high and low beams manually. Drivers sometimes forget to alternate between high and low beams, and at the same time drivers alternate manually. It will also affect the safe driving of vehicles and easily cause traffic accidents

In addition, when a vehicle enters a tunnel during the day, the ambient light suddenly changes from bright to dark, causing temporary blindness to the driver, which can easily lead to traffic accidents. Therefore, the vehicle needs to turn on the headlights in advance before entering the tunnel, and some vehicles are equipped with automatic The headlights are controlled to turn on the headlights after the light is dimmed, so the above problems cannot be solved well.
