1. The Rise of NVIDIA DRIVE in Autonomous Vehicles
1.1 Autonomous Driving Levels and Computational Demands
The Society of Automotive Engineers (SAE) defines six levels of driving automation, from Level 0 (no automation) to Level 5 (full automation). As vehicles advance from Level 2 (partial automation) toward Level 5, they must process exponentially more sensor data in real time, running sophisticated perception, planning, and control algorithms with strict latency and safety requirements. Key computational challenges include:
- Sensor Fusion: Combining data from cameras, LiDAR, radar, and ultrasonic sensors to form a unified environmental model.
- Perception: Object detection, classification, and tracking using deep neural networks (DNNs).
