Levels of Automation

The progression toward fully autonomous vehicles is categorized into six levels, as defined by the Society of Automotive Engineers (SAE):

Level 0 (No Automation): The driver has full control of the vehicle at all times.

Level 1 (Driver Assistance): Systems like adaptive cruise control assist the driver but require constant supervision.

Level 2 (Partial Automation): The vehicle can perform steering and acceleration/deceleration, but the driver must remain engaged.

Level 3 (Conditional Automation): The vehicle can handle most driving tasks, but human intervention is required in certain conditions.

Level 4 (High Automation): The vehicle can operate autonomously in specific environments without human input.

Level 5 (Full Automation): The vehicle is fully autonomous and capable of operating in all conditions without any human involvement.
