Vehicular night curve auxiliary and vision enhancing device and method thereof

Abstract

The invention discloses a vehicular night curve auxiliary and vision enhancing device, which comprises a follow-up steering illuminating subsystem, an infrared night viewing subsystem, an embedded processing control platform and an LCD (liquid crystal display) screen. The embedded processing control platform is used for acquiring and transmitting vehicular state information and calculating control quantity of the follow-up steering illuminating subsystem to control the follow-up steering illuminating subsystem, and further used for acquiring and processing video signals of the infrared night viewing subsystem. The embedded processing control platform is respectively connected with a vehicular CAN (controller area network) and the follow-up steering illuminating subsystem through CAN bus interfaces, and further connected with an infrared CCD (charge coupled device) camera through a video transmission cable/interface. The embedded processing control platform is connected with the LCD screen. By means of full utilization of the automobile electronic technique and the microelectronic technique and completely technical combination, the visual field is expanded for a driver driving at night, hazardous situation perceptual ability of the driver under adverse conditions can be improved, and accordingly night driving safety can be improved.

Description

technical field [0001] The invention relates to an automobile safety driving assistance system, in particular to a night curve assistance and vision enhancement system. Background technique [0002] In recent years, with the rapid growth of my country's car ownership, the road transportation safety situation has become increasingly severe. In 2008, there were 265,204 road traffic accidents across the country, resulting in 73,484 deaths and direct property losses of 1.01 billion yuan. According to statistics, the number of fatalities in accidents that occur at night without street lighting accounts for more than 30% of the total, and accidents that occur at bends account for about 13% of the total. [0003] Infrared night vision technology is divided into active and passive. Active infrared night vision technology is a night vision technology that implements observation by actively illuminating and using the infrared light reflected by the target to reflect the infrared sou...

Problems solved by technology

[0007] (1) The two are controlled by their own independent ECUs, which is not conducive to the full fusion of information and affects the fit of the two subsystems;

[0008] (2) The space utilization of the body is not high, there are many wires, the connection is complicated, and the mass of the vehicle is increased
