The Six Levels of Vehicle Automation

The Society of Automotive Engineers (SAE) International has established a widely accepted classification system for vehicle automation, ranging from Level 0 (no automation) to Level 5 (full automation). Understanding these levels is key to comprehending the capabilities of various vehicle automation systems.

Level 0: No Automation

Description: The human driver performs all driving tasks.
Examples: Older vehicles without any automated assistance features.

Level 1: Driver Assistance

Description: The vehicle can assist with either steering OR acceleration/braking, but not both simultaneously.
Examples: Adaptive Cruise Control (ACC) or Lane Keeping Assist (LKA).

Level 2: Partial Automation

Description: The vehicle can assist with both steering AND acceleration/braking simultaneously, but the driver must remain engaged and monitor the environment.
Examples: Systems like Tesla Autopilot or GM Super Cruise, where the vehicle handles multiple tasks under driver supervision.

Level 3: Conditional Automation

Description: The vehicle can perform all driving tasks under specific conditions, and the driver is not required to monitor the environment constantly. However, the driver must be ready to take over when prompted.
Examples: Mercedes-Benz DRIVE PILOT, which allows hands-free driving in specific traffic jam situations.

Level 4: High Automation

Description: The vehicle can perform all driving tasks and monitor the driving environment under specific conditions, such as within a geofenced area. The driver may not be required to intervene, even if a system failure occurs.
Examples: Robotaxis operating in designated zones, designed to function without human input.

Level 5: Full Automation

Description: The vehicle can perform all driving tasks under all conditions, equivalent to a human driver. No human intervention is required at any point.
Examples: Fully autonomous vehicles that can operate anywhere, anytime, without a steering wheel or pedals.
