ADAS stands for Advanced Driver Assistance Systems, which are electronic systems in a vehicle that use advanced technologies to assist the driver. ADAS includes many active safety features, and often the terms “ADAS” and “active safety” are used interchangeably. These systems use sensors and cameras to detect nearby obstacles or driver errors and respond accordingly. ADAS can enable various levels of autonomous driving. Some of the components that make up the ADAS system have already been deemed mandatory safety systems in cars, such as speed limit assist, lane keeping technology, and a fatigue detection system. Other features of ADAS include cameras positioned around the car that analyze the surroundings from all sides, active cruise control using radar sensors, lane control system, automatic braking system, overtaking assistance with blind spot control, and HUD on the windshield. ADAS features that provide information will most commonly include “warning” in the name, while features that take action beyond a simple warning will most commonly include “assistance” in the name. The goal of ADAS is to prevent collisions and accidents by offering software that alerts the driver to potential problems or to avoid collisions by implementing safeguards and taking over control of the vehicle.
