Parking sensors are proximity sensors for road vehicles which can alert the driver to unseen obstacles during parking manoeuvres. The whole system is sometimes referred to as Park Distance Control (PDC).
Parking sensors generally fall into two categories.
1. Electromagnetic parking sensors
These rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once detected the obstacle, if the vehicle momentarily stops on its approach, the sensor continues to give signal of presence of the obstacle. If the vehicle then resumes its manoeuvre the alarm signal becomes more and more impressive as the obstacle approaches. Electromagnetic parking sensors are often sold as not requiring any holes to be drilled offering a unique design that discreetly mounts on the inner side of the bumper preserving the 'new factory look' of your vehicle
2. Ultrasonic parking sensors
The rest of this posting refers to ultrasonic parking sensors only.
The ultrasonic sensors are currently available in several brands of cars, with a variety of brand names such as Parktronic and Parking Aid. Some systems are also available as additional upgrade kits for later installation.

“That’s interesting. Sort of a private preserve for teenagers, huh? I suppose as adults we’re lucky to find a parking space.”
