The invention provides a night vision system in front of a vehicle, which does not need special field angle adjustment equipment, and can electrically adjust the field of view angle while looking at a vehicle display device. The vehicle front night vision system includes: an infrared camera (10), which has a CCD element (12) that converts the image in front of the vehicle into an electrical signal and a microcomputer (13) that generates a video signal according to the electrical signal; the night vision system controls (ECU 30), which controls the timing of the synchronization signal contained in the video signal by controlling the action of the microcomputer (13); the head-up display (20), which displays images according to the video signal. The night vision system control (ECU 30 ) incorporated in the in-vehicle LAN receives a viewing angle command signal from an adjustment device ( 70 ) outside the vehicle via the in-vehicle LAN. The night vision system control (ECU 30) controls the timing of the synchronous signal so as to display the image at the viewing angle according to the viewing angle command signal.
Description
technical field [0001] The invention relates to a vehicle front night vision system. Background technique [0002] In the past, when the vehicle was driving at night, it was difficult for the driver to see clearly with the naked eye in the far distance (for example, about 100m to 400m from the front of the vehicle) where the headlights of the vehicle could not shine. become the cause of traffic accidents. [0003] Therefore, the scheme of the night vision system in front of the vehicle has been proposed in recent years, that is, to use the vehicle night vision camera to capture the image of the place with poor vision as mentioned above, and display it on the vehicle display device, so as to assist the driver's vision at night and ensure the safety of the vehicle. safe operation. In addition, according to such a night vision system, by using the moving light beam of the headlight (hereinafter referred to as high beam), it is possible to display the distance ahead of the veh...
