Automatic parking of vehicles, from simple parking aids that find objects and help the driver to navigate, differ in the ability of parallel parking in narrow places, almost without help from the driver. Automatic parking systems usually use acoustic and / or radar sensors of the distance that find the presence or absence of other vehicles, walls or people in the immediate vicinity of the car. They can also use images sensors that recognize borders and drawn lines on the asphalt. Most automatic parking systems are able to use these sensors for parallel parking. The automatic parking system is activated by pressing the button on the dashboard. It measures the distance between vehicles using ultrasound sensors and determines whether there is enough space for parking. Then it works, rotating the steering wheel automatically, and can give commands to the driver switch the gears and press the accelerator pedal.
