AI Technical Summary

Technical Problem

In a two-way, two-lane ordinary road tunnel, when the vehicle turns on the high beam, it has a serious impact on the vision of the opposite driver, increasing the risk of traffic accidents. The existing technology cannot adjust the light intensity and color temperature of the tunnel lighting device in real time.

Method used

The dynamic high beam recognition system is used to identify vehicles that turn on the high beam in real time, and through the delayed tunnel lighting adjustment system, the light intensity and color temperature of the lighting device in the tunnel are adjusted in real time according to the vehicle speed and traffic data, so as to reduce the impact of the high beam on the driver of the vehicle.

Benefits of technology

By adjusting tunnel lighting in advance, it reduces the time for drivers of direct vehicles to adapt to the impact of high beams, reduces the stimulation caused by rapid change of the light intensity of the lighting device, and improves driving safety.

Abstract

The invention belongs to the technical field of automobile active safety, and discloses a bidirectional double-lane ordinary highway tunnel high beam linkage lighting device and method, and the device comprises a dynamic high beam recognition system, a delayed tunnel lighting adjustment system and a wireless communication module. The speed, average speed and traffic flow of vehicles at each sampling point in a tunnel are calculated through a dynamic high beam recognition system, whether high beams of the vehicles are turned on or not is judged, the light intensity of the vehicles turning on the high beams is marked, and lighting control information is generated through a delayed tunnel lighting adjustment system, so that the light intensity and color temperature of a tunnel lighting device are adjusted; by means of the device and the method, dynamic delayed illumination capable of reducing negative effects of the high beam in the tunnel can be achieved, the whole adjusting process is smooth, a driver is helped to adapt to light changes, and stimulation and discomfort caused by changing of light intensity and color temperature of the illumination device are reduced.
