What is ADAS?
Advanced Driver-Assistance Systems (ADAS) are electronic technologies that assist drivers with safety and driving functions. These systems use sensors, cameras, radar, and software to detect hazards and help prevent accidents.
- Automatic emergency braking can detect obstacles and apply brakes without driver input
- Lane departure warning and lane-keeping assist help maintain proper lane position
- Adaptive cruise control adjusts speed to maintain a safe following distance automatically
Levels of Autonomy
The SAE defines six levels of driving automation, from Level 0 (no automation) to Level 5 (full automation). Understanding these levels helps set realistic expectations about what current and future vehicles can do.
- Level 0-1: Driver does everything or gets minor assistance like adaptive cruise control
- Level 2-3: Partial to conditional automation — the car can steer and brake but requires driver attention
- Level 4-5: High to full automation — the vehicle handles all driving tasks in defined or all conditions
Current Technology
Today's most advanced consumer vehicles operate at Level 2 to Level 2+ autonomy, with some approaching Level 3 in specific conditions. EVs are at the forefront of these developments thanks to their software-centric architectures.
- Tesla Autopilot, GM Super Cruise, and Ford BlueCruise offer hands-free highway driving
- Over-the-air software updates continuously improve ADAS capabilities after purchase
- Camera, radar, lidar, and ultrasonic sensor fusion provides comprehensive environmental awareness
