Advanced Driver Assistance Systems, or ADAS, is a high technology system developed to help drivers attain safe driving which consequently creates an overall secured and accident-free traffic movement both for car travelers and pedestrians. An ADAS unit deployed in a car is commonly composed of a processor, input sensors, a Controller Area Network or CAN interface and probably a video display.

Similar to any computer processor, an ADAS processor is tasked to execute commands for a specific system deployed in the car. ADAS is able to ensure safe driving because this technology is designed to make accurate predictions based on certain factors detected by its input sensors such as light, speed and the environment. The CAN interface allows ADAS slave devices to communicate with each other even at the absence of a host. Information is oftentimes relayed to the driver by a display of data in a console.

To significantly reduce the occurrence of car collisions which is the leading cause road injuries and death, and to comply with the requirements for added vehicle safety, most car manufactures employ ADAS in the production of their new car models. Typical examples of ADAS are GPS navigation system, pedestrian protection system, night vision system, lane change warning system and automatic parking system.
