The components of the driverless car technology systems consist of lasers, cameras, Global Positioning System, radar, processors, and complex software systems as stated by Knight (2012). In the below figure, BMW’s robocar with autonomous vehicle technology features have been shown and it includes, Global Positioning System, high definition camera, ultrasonic sensors, laser, radar, and computer.
The autonomous vehicle can be described by the technology in three steps: —
Step1: -As per (IHS Automotive, 2014; Knight, 2012), Global Positioning System allows the vehicle to identify its own position and also perceiving the environment. Obstacles can be identified by using cameras, lasers, and radars.
let’s say other vehicles, pedestrians, bikers,, or constructions site on the road and identify the distances. In the below figure, street objects such as road signs, other vehicles, pedestrians, and cyclists can be recognized by the sensors and camera.
Step2: – The input data have to be accumulated and processed by the software and processors so that the driverless car can make a sense out of it to operate in the real world as per the road signs. (Knight, 2012).
Step3: — The vehicle movement is possible in real-time as per the reaction and adaption of the system. (Knight, 2012). In the below figure, the driverless car can react and alternate its movement.
