Autonomous vehicle levels refer to the SAE International standard (J3016) that classifies driving automation from Level 0 to Level 5 based on the degree of human involvement and system capability. Here’s a concise breakdown:
- Level 0 (No Automation): The human driver controls all aspects of driving (steering, acceleration, braking) with no assistance from the vehicle. Basic warnings (e.g., blind-spot alerts) may exist but don’t intervene.
- Level 1 (Driver Assistance): The vehicle can assist with either steering (e.g., lane-keeping assist) or acceleration/braking (e.g., adaptive cruise control), but not both simultaneously. The driver remains fully responsible.
- Level 2 (Partial Automation): The vehicle can control both steering and acceleration/braking in specific scenarios (e.g., highway driving) using systems like Tesla’s Autopilot or GM’s Super Cruise. The driver must monitor the system at all times and be ready to take over.
- Level 3 (Conditional Automation): The vehicle can handle all driving tasks in certain conditions (e.g., traffic jams or highways) and will prompt the driver to take over when needed. The driver can disengage from monitoring but must respond to requests. Example: Audi’s Traffic Jam Pilot (in limited markets).
- Level 4 (High Automation): The vehicle can perform all driving tasks in specific environments or conditions (e.g., geofenced urban areas) without human intervention. It can handle emergencies independently, but human override is possible. Example: Waymo’s driverless taxis in designated areas.
- Level 5 (Full Automation): The vehicle is fully autonomous in all conditions and environments, requiring no human input or presence. No steering wheel or pedals are needed. This level is still theoretical, with no commercial examples as of April 2025.
