What is?
also known as ADAS advanced driver assistance systems. Using the camera mounted on a vehicle, with radar, laser sensors and other equipment on the surrounding environment for analysis, the necessary assistance to people driving vehicles through the computer, and in order to ensure driving safety.

The main configuration
Technical content
the ADAS system including driver assistance, emergency alert and active safety in three areas.
including electronic stability system, adaptive cruise control, a lane deviation warning system, a lane keeping system, a forward collision warning system, the automatic emergency brake system, blind spot detection. Even the traffic sign recognition, night vision system, automatic parking systems. Configure applied vary according to each brand.

principle
· ADAS driver assistance system which works by installing when will collect various types of sensors on the car road information, road conditions were analyzed by image processing and image analysis technology, we found a dangerous situation made by the driver warning, intervention vehicle control.
– which consists of three parts external sensor, ECU, the actuator composition. The main sensor is a vehicle traveling road environment for data collection. Data collected by sensors ECU back part of the analysis process, determining driving conditions, road conditions. The controller judged dangerous situation, it outputs a control signal to the actuator to complete the respective safety action by the actuator.
ADAS-sensor type systems, there are many, there are laser radar, millimeter wave radar, an ultrasonic radar, infrared, and cameras.

From the current point of view autopilot grade ADAS advanced driver assistance systems to achieve level 3, but the development from level 3 to level 4, needs more cars with autopilot technology that requires construction of road infrastructure (camera on the road, clear lane line) perfect. Internet need a car, car phone Internet and so on.
