Self Study Program 462 – Audi A8 2010 Night Vision Assist
VAG SSP 462. Night Vision Assist, the latest driver assistance system by Audi, has been designed to specifically meet this challenge. In the dark, Night Vision Assist enables the driver to detect persons ahead of the vehicle much sooner than without it.
Recent years have seen many innovations in the field of automotive driver assistance systems. Driver assistance systems aid drivers by providing comfort and safety, but without relieving them of the responsibility for their own actions. They are one of the reasons for the decline in the number of fatalities resulting from road accidents, despite the ever-increasing number of road users. Many of these systems help to prevent accidents by alerting the driver to impending hazards.
The advantage of early detection is that the driver has more time to react to the hazardous situation ahead.
Animals can also be seen on the display even before they come within the range of the vehicle’s headlights. The night vision system is, therefore, a real advancement. It not only provides better illumination of the road, but also allows the situation ahead of the vehicle to be interpreted more quickly and accurately in the dark. Its range greatly exceeds that of the main-beam headlights. The function has been implemented using a thermal imaging camera, which means that heat-emitting objects, such as human beings and animals, stand out clearly against their background.
The above illustration clearly demonstrates the advantages of the Night Vision Assist system for drivers. The pedestrian crossing the road can only be vaguely discerned through the windscreen. A quick glance at the Night Vision Assist display, however, reveals the pedestrian in full size.
The brightly coloured pedestrian clearly stands out against the background and is bracketed in red to alert the driver to the danger of a collision. By detecting the pedestrian sooner, the driver has more time to react appropriately to the hazardous situation ahead.
