Advanced driver assistance systems (ADAS) use a variety of sensors installed on the car (millimeter wave radar, lidar, monocular and binocular cameras, and satellite navigation) to sense the surrounding environment at any time during the driving process of the car, collect data, identify, detect and track static and dynamic objects, and combine navigation map data to perform systematic calculations and analysis, so as to allow drivers to be aware of possible dangers in advance, effectively increasing the comfort and safety of car driving.

The initial stage of ADAS technology is generally called driver assistance (DAS), which is generally at the L1~L2 level of autonomous driving. The functions of traditional driver assistance systems (DAS) are generally based on simple vehicle status information for judgment and execution (such as ESC), without the need to perceive the surrounding environment. Advanced driver assistance systems (ADAS) have sensors used to collect and analyze information in the surrounding environment of the car, and can perform complex signal processing as needed to support corresponding driving tasks.
