Advanced Driver Assistance Systems are a variety of technologies combines to improve the safety of a vehicle in its environment, as well as its occupants.

Some systems have manual intervention and settings, such as Automatic Cruise Control, while others are automatic and enabled specifically for safety-critical applications – such as Automatic Emergency Braking.

ADAS provides the foundation for technologies which enable autonomous driving because it needs sensors (ultrasonic, RADAR, LiDAR, camera), processing (on board centralised or multiple decentralised processors) and considerable research and development work in algorithm development, safety testing and vehicle control.
