What does the acronym "ADAS" stand for in automotive safety?

In automotive safety, ADAS stands for Advanced Driver-Assistance Systems.

ADAS is a broad category of electronic technologies that help drivers operate, park, or control a vehicle more safely. These systems use combinations of cameras, radar, lidar, ultrasonic sensors, wheel-speed data, and software to monitor the road and the vehicle’s surroundings. Depending on the feature, ADAS may warn the driver, provide steering or braking assistance, or temporarily control part of the driving task.

Examples include adaptive cruise control, forward-collision warning, automatic emergency braking, lane-departure warning, lane-keeping assistance, blind-spot monitoring, and parking assistance. The plural “systems” matters because ADAS refers to a family of functions rather than one single device. It is often confused with fully autonomous driving, but most ADAS features still expect the human driver to supervise the vehicle.

The roots of modern driver assistance include cruise-control experiments from the mid-20th century and production anti-lock braking systems adopted in the 1970s. Electronic stability control and other sensor-based features later expanded the field. Manufacturers may use different brand names for similar functions, which is why standardized terminology remains important.
