- Radar and Cameras: Radar and cameras provide additional layers of perception, enabling the vehicle to sense objects, pedestrians, and other vehicles in real-time.
b. Artificial Intelligence (AI) and Machine Learning
- Decision-Making Algorithms: AI algorithms process sensor data to make real-time decisions, such as steering, braking, and acceleration.
- Machine Learning Adaptability: Self-driving cars use machine learning to continuously improve their performance by learning from various driving scenarios.
III. Levels of Automation: Understanding Autonomy
a. SAE Levels of Automation
- Level 0-2: These levels involve partial automation, where the driver maintains control but may receive assistance in specific tasks.
- Level 3: Conditional automation allows the car to handle certain driving scenarios, with the driver as a fallback.
- Level 4-5: High and full automation describe vehicles capable of performing most or all driving tasks without human intervention.
b. Current Industry Focus
- Commercial Fleets: Companies are deploying self-driving technology in commercial fleets for applications like ride-hailing and goods delivery.
- Consumer Vehicles: While fully autonomous consumer vehicles are in development, current focus is on enhancing driver assistance features in conventional cars.
