Advanced Driver Assistance Systems (ADAS) are a variety of technologies combined 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 that enable autonomous driving because it needs sensors (ultrasonic, RADAR, LiDAR, camera), processing (onboard centralised or multiple decentralised processors) and considerable research and development work in algorithm development, safety testing and vehicle control.
