- The Society of Automotive Engineers defines six levels of driving automation, ranging from Level 0 to Level 5.
- Level 1 and Level 2 vehicles involve driver assistance and partial automation, requiring the driver to keep hands on or be ready to intervene.
- Level 3, Level 4, and Level 5 represent conditional, high, and full automation where artificial intelligence takes over driving tasks under specific or all conditions.

To classify the autonomous vehicles, the Society of Automotive Engineers defines the standard levels of automated driving. This standard has become a de facto global standard in the Autonomous Vehicle Technology. Thrair are six levels of driving automation defined in the standard, ranging from Level 0 to Level 5. Level 0, No Automation. Level 1 or Driver Assistance,
Level 2 or Partial Automation. Level 3 is Conditional Automation, Level 4 or High Automation, and Level 5 is Full Automation. As per researchers, we would see approximately 8 million autonomous or semi-autonomous vehicles on the road by 2025. Let us try to understand the standards in details.
Most vehicles on the road nowadays belongs to Level 0 category. In this level, the vehicle completely depends on the driver for every driving action. An example would be a proximity sensor that lets driver know when he is about to hit an object. Level 0 vehicles does not qualify as an autonomous vehicles. Suppose if your car itself can control anything based on the inputs that captures from surroundings, then it belongs to Level 1 category. This is the lowest level
of automation, where vehicle at least should have a single automated system for driver assistance. Here both driver and the automated system shares the control of vehicle. It often referred as hands-on, as driver always needs to keep his hands on steering.
Vehicle with cruise control is a good example for Level 1 vehicle, in which the driver controls steering, and the automated system controls the engine power, to maintain a set speed. Another example is lane assistance system, where system warns the driver if the vehicle is leaving its lane with visual, audible, or through a vibration warning. In Level 2 vehicles, advanced driver assistance system controls, acceleration, braking, and steering. It also referred as
hands-off, however, the driver must be able to intervene immediately at any time if the automated system fails to respond properly. Nissan's ProPilot Assist is a Level 2 driver assistance system. It can keep you at a safe distance from the car in front of you at a preset distance and help to keep the vehicle centered during single lane driving. Tesla's Autopilot, GM's Super Cruise, and Volvo's Pilot Assist, are other examples of Level 2
autonomous vehicle systems. Level 3 vehicles can be truly considered as autonomous. These vehicles have environmental detection capabilities and it can make informed decisions, like emergency braking and lane changing. As drivers are allowed to turn their attention away from the driving tasks, this kind of vehicles are referred as eyes-off. But driver must still require to intervene within some limited time that is defined by the manufacturers,
when a notification comes from the vehicle to take control. Audi's A8L is the first car that meets Level 3 automation standards. The Audi AI traffic jam pilot can take over all aspects of driving in slow-moving traffic up to 37.3 mph. Level 4 vehicles are highly automated vehicle and the vehicle won't drive if all the predefined conditions are not met.
Cars are referred to as mind-off because the systems in the vehicle controls steering, braking, acceleration and monitors the environment without human intervention. There are some restrictions as the full self-driving mode can only be activated in certain, geofenced areas or in traffic jams. If there is a system failure, the car can still ask the driver to take back control, but if it receives no response, the car is able to bring
itself to a safe stop. Waymo, formerly the Google self-driving car project, is the best example of a Level 4 vehicle. Waymo already started a limited trial of a self-driving taxi service in Phoenix, Arizona. A French autonomous vehicle manufacturer, Navia, has already building and selling fully self-driving vehicles, Autonom Cap and Autonom Shuttle in the United States,
with Level 4 standard. In Level 5 vehicles, artificial intelligence AI drives the car entirely on its own and every person in the car becomes a passenger. Systems inside fully autonomous vehicle itself monitor the surroundings and controls all driving tasks, under all conditions including complex driving conditions like busy pedestrian crossings.
As per the standard, vehicles will be free from geofencing and able to go anywhere and do anything that an experienced human driver can do. Although there are lots of talk about fully autonomous vehicles, at this point, none are yet available to the general public. While the future of autonomous vehicles is promising and exciting, due to regulations and legal battles, Level 5 vehicles are probably still many years away. The collective effort of our
researchers, engineers and problem solvers from various disciplines will definitely make the autonomous car on the road a reality.
