Levels of Autonomous Driving
Levels of Autonomous Driving:
The Society of Automotive Engineers (SAE) has defined six levels of autonomy in driving. These levels categorize the level of automation, ranging from no automation (level 0) to full automation (level 5). Each level represents a progression in the vehicle's ability to control itself and interact with its surroundings. As we move up the levels, the reliance on human input decreases, and the vehicle takes on more responsibility for driving tasks. These levels serve as a guideline for understanding the capabilities and limitations of autonomous vehicles.
A Understanding the SAE Autonomous Driving Levels
The Society of Automotive Engineers (SAE) has established six levels of autonomy in driving to classify the degree of automation.
