Definition
In transport, AI powers route planning, traffic prediction and driver assistance, up to self-driving vehicles. In manufacturing, it powers visual quality inspection and predictive maintenance. SAE defines six levels of driving automation, from 0 (none) to 5 (full).
In simple words
Maps guess your arrival time from traffic. Factory cameras spot scratches faster than the human eye. Sensors notice that a machine sounds wrong and warn before it breaks.
Why it matters
These are large, practical uses of AI. Self-driving also shows how the last few percent of reliability can be the hardest part of all.
How it works
| SAE level | Who is driving |
|---|---|
| 0 | The person. No automation. |
| 1 | The person, with steering or speed help |
| 2 | The person watches, while the car steers and controls speed |
| 3 | The car, in set conditions, and the person must take over on request |
| 4 | The car, within a limited area, with no person needed |
| 5 | The car, everywhere |
Try it yourself
Handing over the steering wheel
Move up the six levels of driving automation, and watch who is responsible.
Who is driving?
Match each car to its SAE automation level. The table above will help.
- An old car with no driving help at all
- The car only keeps the speed. The person does everything else
- The car steers and controls speed while the person keeps watching
- The car drives in set conditions and may ask the person to take over
- A taxi with no driver that runs only inside one city area
- A car that can drive itself anywhere, with no person needed
Common mistakes
- Trusting driver-assist features as if the car drives itself.
- Assuming models trained abroad handle Indian roads.
Check yourself
Summary
- Routes, traffic, inspection and maintenance are widely used now.
- SAE levels run from 0 to 5.
- Most driver-assist cars still need a watching driver.
