Front, back, left and right – a total of four laser scanners measure the precise distances to other objects and detect size and speed as well as the entire surroundings of the vehicle. The vehicle is then able to form a picture of which areas are accessible and free of obstacles.
The series camera installed in the inside mirror is able to determine the position of other road users and distinguish between a passenger car, lorry, motorcycle or pedestrian. It also recognises the road markings and uses it to supply information on the position of the car within its lane.
The radar installed both in the front and two times in the back uses radar waves to measure the position of other vehicles and detects which direction they are coming from, how far away they are and the speed at which they are moving.
