Parking Dynamics PD1 Sensors

How do the PD1 sensors work? In the rear of the car you have the reverse sensor. This sensor has three zones that it will read. As you get closer to an object the PD1 reverse sensor will do a self diagnosis. As you reach zone 1 the first stage you will hear a ‘be-be-be’ sound. It is a slow cautionary sound. As you get into zone 2 the sound will be faster and edges you towards being extremely cautious in backing up. The last zone, 3, is going to be a constant ‘beee’ sound. In other words you need to stop the reverse process and re- position. The reverse sensor of the PD1 is engaged when you place the car in reverse.

The front parking sensor works a little differently. First there are only two zones. The first zone is a warning ‘be- be- be’ that will increase in frequency as you get closer to an object. The second zone will be that low frequency constant ‘beep’ sound. This is of course when you want to stop and re- position the car before you cause an accident. The difference in the front parking sensor is that it takes a button below the steering wheel to engage the parking sensor. This button can be pressed at any time to engage the electromagnetic parking sensors.
