Automotive Night Vision – How Does It Work?


The safety devices used in the automotive industry continues to increase in order to prevent the accidents that occur mostly due to the vehicle crashing at the night time or in the darker areas. With the advancement in technology and the market of the driverless cars and the auto gear shift cars available, the need for incorporating a safety measure better than the previous models has become important.

Automotive Night Vision

The automotive night vision is nothing but the systems in the automotive industry, in order to help in guiding the drivers through the darkness. Usually, the drivers use the head lights under dark conditions to drive safely. But two cars when coming opposite to each that tend to create a glaring effect due to the brightness of the headlights which again causes crashes.

So, the alternative approach for safety is the automotive night vision systems. There are a number of systems such as the thermographic camera, infrared lights, head up displays, and other technologies in automotive and they help to improve the vision in the darkness.

How Does It Work?

The automotive systems are mostly useful for the cars in order to help the driver to view the vehicles clearly in the night time. The working of the automotive systems is classified into two different categories namely; the active system and the passive system. Let us look at them in detail.

Active system- The active system works with the help of the infrared light; which is designed in the car, as a primary source to help the driver to see the roads in the invisible areas better when compared to using the headlights.

As the infrared rays are outside the visible spectrums of light, they avoid creating blindness with the bright light unlike the head up beams. Further, the system is classified into two different types such as the gated and the non-gated systems, where the gated systems make use of the synchronized camera along with the pulsed light source which helps in higher performance more than 250m length.

Passive system- The passive system, on the other hand, avoids using the infrared system and makes use of the thermographic camera to capture the thermal radiations emitted by the vehicles. As most of the animals and vehicles emit thermal radiation, it is very beneficial for drivers who drive in the darker areas. Also, the range of this particular system is higher when compared to the previous system.

However, the image captured by the thermographic camera is not better when compared to that of the active system’s camera and they are not capable of working in the warm temperature areas.

Does It Help In Reduced Accidents?

In general, most of the vehicle crashes takes place during the twilight hours due to the lack of the lights. Hence, the use of the technologies that are capable of providing night vision does help in reducing the night accident cases as they are capable of detecting objects that are 500 feet away.

Thus, the proper use of the night vision technology can benefit the automotive industry to show a reduced number of accidents by alerting the driver at a proper time.
