How Self Driving Car Work

Self-driving cars integrate a wide array of sensors, computing modules, connectivity equipment and AI software to enable autonomous operation:

  • Cameras: High-resolution cameras capture images and video to provide visual data. Some systems use up to 10 cameras for 360-degree coverage.
  • Radars: Radar sensors bounce radio waves to detect objects at long ranges and measure distances, similar to how autonomous cruise control works.
  • LiDARS: LiDAR (Light Detection and Ranging) systems shoot millions of laser beams per second to generate precise 3D mapping of the car's surroundings.
  • Ultrasonics: Short-range ultrasonic sensors measure proximity to obstacles during parking and low-speed maneuvers.
  • GPS: Global positioning system modules provide localization by continuously tracking the vehicle's geographic coordinates.
  • Maps: Pre-generated high-definition maps support navigation and real-time location data.
  • Control Units: Actuators control acceleration, braking, and steering through drive-by-wire.
  • Machine Learning Compute: Powerful GPUs and AI chips provide computing power to run advanced neural networks.

All this hardware generates massive data that feeds into the autonomous driving software stack. The AI-powered perception, prediction, planning, and control modules process sensor data to understand the environment and operate the vehicle.

Levels of Autonomy

There are 5 levels of autonomous driving capabilities:

Level 1

Driver assistance features like automated emergency braking, adaptive cruise control or lane keeping. The driver must constantly monitor and be ready to take control.

Level 2

Steering or acceleration/deceleration assistance. The driver must still continuously pay attention to the road and surroundings.

Level 3

The vehicle can independently monitor its surroundings and make some driving decisions, but human override is still required.

Level 4

Fully self-driving within certain conditions like designated areas or good weather. The human takeover may eventually be needed.

Level 5

The highest level of autonomy with robust self-driving abilities in all conditions. No human intervention is ever required. This is the end goal of R&D, but it does not yet exist.

AI Perception Systems

The fundamental capability underpinning autonomous mobility relies on accurately perceiving contextual elements around the vehicle for intelligent adaptations. Multiple cameras, lidar sensors and radars gather continuous streams of visual data arrays tracking static, dynamic and fleeting aspects like road curvatures, traffic signaling systems, junctions, surrounding vehicles, pedestrians, stray animals and obstruction objects along the intended route.

High resolution camera feeds blended with low light infrared or depth detecting lidars offer rich scene understanding for what lies ahead to around 300 meters relative to simple cameras limited to 150 meters. Radar scans penetrate fog, rain and snow conditions where optical systems falter. Sensor fusion algorithms then stitch composite operational views labeling aspects before streaming into path planning modules. Here AI neural networks running object classification and prediction codes categorize trees, pets, potholes and more amidst endless permutations with remarkable accuracy determining influence zones for navigational decisions afterwards.
