- Level 1: Some assistance, like cruise control.
- Level 2: Partial automation, like lane-keeping and adaptive cruise control together.
- Level 3: The car can handle most tasks but still needs a human for tricky situations.
- Level 4: Full automation in specific areas or conditions, like city streets.
- Level 5: Complete autonomy. The car can drive anywhere, anytime, without human input.
So, a Level 5 car is the dream of fully self-driving vehicles. Let have a look the features of this AI-driving technology
Key Features of Self-Driving Cars
For a car to drive itself, it needs to “see” the road, “think” about its surroundings, and “decide” what to do next. Here’s how it works:
- Sensors
Sensors act like the car’s eyes. They scan the environment to detect other cars, pedestrians, and obstacles.
Example: What if the car is approaching a traffic light? The sensors recognize the red light and tell the car to stop. - Cameras
Cameras capture detailed images of the road, traffic signs, and lanes. They help the car identify things like a stop sign or a child crossing the street. - LIDAR (Light Detection and Ranging)
LIDAR uses lasers to map the surroundings in 3D. It helps the car measure distances and understand the size of objects nearby.
Example: LIDAR can tell if the object ahead is a small box or a large truck. - GPS and Maps
GPS guides the car to its destination. Combined with maps, it ensures the car stays on the right route.
Example: Just like you use Google Maps, the car uses GPS to avoid taking a wrong turn.
