**5. Various sensors of ADAS**

It is extremely important to know which sensors are required for autonomous driving from Levels 1 to 5. As already mentioned, there are three main groups of sensor systems camera-, radar-, and LIDAR-based systems. Although, for parking, ultrasonic sensors are available today and are widespread, they are of minor importance for autonomous driving. Camera and radar systems are in the Level 1 and 2 vehicles today and are prerequisite for all further levels of automation.
