TO A FULLY DRIVERLESS CAR
The National Highway Traffic Safety Administration, and most automated car developers, use a six-stage progression to describe automated driving systems, moving from complete driver control to full autonomy.
The human controls it all – like we've been doing all along.
Most functions are still controlled by the driver, but a specific function( like steering or accelerating) can be done automatically by t he car.
The car takes over two or more functions. For example, t here might be adaptive cruise control combined with technology that keeps a car in its lane. Level 2 cars are already on the road.
Drivers are still behind the wheel at all times, but t hey abdicate control under certain conditions — on motorways, for example, or at certain speeds. The driver must be ready to take over at anytime, with the car allowing sometime to make the transition. Such cars are being tested but are not yet on the market. Still, they might be available before 2020.
The vehicle is fully autonomous under most but not all driving scenarios. All the driver needs to do is say where he or she wants togo, then sit back and enjoy the ride. Level 4 might exclude conditions like gravel roads or extreme weather. Experts say level 4 cars are likely to appear sometime between 2020 and 2025, probably nearer 2025 in New Zealand.
This refers toa fully autonomous system that expects the vehicle’ s performance to equal that of a human driver in every driving scenario. At this“automated chauffeur” level, a blind person or a child could hop in the car. We are probably looking at 2030 or beyond for this level.
