Understanding the Levels of Vehicle Autonomy

Before diving into the details of fully autonomous cars, it is essential to comprehend the levels of automation established by the Society of Automotive Engineers (SAE) to classify the different stages of autonomous driving capabilities.

  • Level 0: No automation. The driver is responsible for all aspects of driving.
  • Level 1: Driver assistance. The vehicle can assist in specific tasks, such as adaptive cruise control or parking assist, but the driver must remain engaged.
  • Level 2: Partial automation. The car can take control of both steering and acceleration/deceleration in specific scenarios, such as highway driving, but the driver must remain vigilant and ready to intervene.
  • Level 3: Conditional automation. The vehicle can manage most driving tasks but may require the driver to intervene in certain situations.
  • Level 4: High automation. The car can operate without human input in specific conditions, such as geofenced areas or designated lanes.
  • Level 5: Full automation. The vehicle can perform all driving tasks under all conditions, without any human intervention.

We will focus on Level 5 autonomy, which represents the ultimate goal of fully autonomous vehicles that can navigate without any human input.
