What is ADAS (Advanced Driver Assistance Systems)?

They use cameras, radar, ultrasonic sensors and sometimes lidar. Most are assistance systems; the driver remains responsible. Many are now required on new cars in the EU. Systems are grouped by levels of driving automation; most current cars offer level 1 or 2, where the driver must monitor the road and keep hands on the wheel. Software updates can change how features behave.

How it works

Control units combine sensor data and act through brakes, steering and engine.

Why it matters for your car

Dirty or misaligned sensors can disable functions. After windscreen, bumper or alignment work, calibration may be needed.
