Steer-by-wire
Steer-by-wire replaces the mechanical link with electronic control.
What is Steer-by-wire?
Sensors read the steering wheel. Motors steer the wheels. Redundancy ensures safety. It allows variable steering ratios, a smaller steering wheel and more flexible interior layouts. Regulations require backup systems so the car can still be steered if a component fails. A few production cars and commercial vehicles have started to use it, and its use is expected to grow with automated driving functions.
How it works
The control unit translates input to wheel angles.
Why it matters for your car
It is still rare. Systems require backups.
