Car proximity sensors do very much what they say on the tin – they sense when your vehicle gets close to an object. How they work is less straightforward, with different types of sensors using different methods to help the driver avoid any nasty bumps.
Ultrasonic sensors, for example, use a type of sonar. Using echo-times from sound waves that bounce off nearby objects, the sensors can identify how far away the vehicle is from said object, and alert the driver the closer the vehicle gets. Electromagnetic sensors create an electromagnetic field around the bumper, and offer an alert whenever objects enter it.
Each system has its own method of alerting a driver through an escalating series of beeps, like the radar in Alien, is most common. In recent years, upgrades have been available, with some vehicles including a digital display which shows the part of the vehicle which is closest to the object.
I hope it helps you
