A night vision navigation integrated system and control method

Abstract

The invention discloses a night vision navigation integrated system and a control method, including a thermal imaging camera, a night vision controller, an instrument, a DVD, a steering wheel angle sensor, a vehicle body control unit, an engine controller, a transmission controller and an electronic stability program; The imaging camera collects road condition images; the night vision controller analyzes the video signal to identify pedestrians, and judges the relative distance and relative distance between the vehicle and pedestrians based on the steering wheel angle signal, vehicle speed signal, and the installation position of the thermal imaging camera speed and predict the trajectory of vehicles and pedestrians, and judge the degree of collision risk of vehicles and pedestrians, and issue different levels of alarm instructions and / or braking request instructions according to the degree of collision risk; the instrument sends out alarm information; the engine controller inhibits the engine The response to the throttle opening generated by the accelerator pedal; the electronic stability program controls the boost cylinder to actively boost. The invention can improve driving safety.

Description

technical field [0001] The invention belongs to automobile active safety technology, and in particular relates to a night vision navigation integrated system and a control method. Background technique [0002] Driving at night, due to insufficient light, it is easy to find traffic accidents. According to statistics, more than half of the traffic fatal accidents occur at night, so a night vision system with pedestrian recognition has appeared. Through this system, pedestrians can be detected in advance compared with high beams, and the driver can be warned by images or sounds, so that it has sufficient Time to take collision avoidance measures. [0003] At present, except for a few high-end models, the passive night vision system mainly displays night vision video images through the car DVD, but there are cases where it works with the DVD navigation function at the same time, and does not have the active braking function. In addition, although the night vision system can de...

Problems solved by technology

[0003] At present, except for a few high-end models, the passive night vision system mainly displays night vision video images through the car DVD, but there are cases where it works with the DVD navigation function at the same time, and does not have the active braking function

In addition, although the night vision system can detect pedestrians in advance, its imaging sense is quite different from that of the human eye, making it difficult to directly view

In addition, when the vehicle speed is high, although the direction of pedestrians can be clearly seen by zooming in on the image (for example, the BMW night vision system provides 1.5 times the image magnification when the vehicle speed is higher than a certain speed), but in the process of driving, the zoomed-in image will cause the image to be blurred. There is a difference between the sense of distance and the real situation, which is not conducive to driving safety
