5 Series E60 M5 (S85) SAL
Important: Responsibility remains with the driver at all times
PDC is unable to take the place of the driver's personal assessment of obstacles.
The ultrasonic sensors have a blind spot. Objects in this blind spot cannot be detected.
The ability to detect objects can stretch the physical limits of ultrasonic measurements (no or poor reflection
of ultrasonic impulses, e.g. trailer tow bars or narrow objects).
Low objects that have already been indicated can "disappear", before a continuous tone sounds (e.g. a
high kerbstone).
The evaluation of obstacles is thus the responsibility of the driver, even with PDC.
Brief description of components
PDC consists of the following components:
-
8 ultrasonic sensors
There are 4 ultrasonic sensors in each of the front and rear bumpers.
The ultrasonic sensors emit ultrasonic impulses. These ultrasonic impulses are reflected by obstacles (echo
impulses).
The ultrasonic sensors receive and amplify these echo impulses. The amplified echo impulses are then
converted into a digital signal. Each ultrasonic sensor has its own microprocessor, its own power supply and its
own data connection to the PDC control unit.

Important: Measuring range of ultrasonic sensors
The measuring range of the ultrasonic sensors is between approx. 25 centimetres and a maximum of
approx. 200 centimetres. If the minimum distance that can be detected rises to an impermissible level, a
fault message is entered in the fault memory.
Dirt contamination, moisture, ice and snow can cause an impermissible rise in the minimum distance that
can be detected.
Note: Cleaning the ultrasonic sensors
To make sure the system remains fully operational, keep the ultrasonic sensors clean and free from ice. Do
not clean by spraying high-pressure washers directly at the ultrasonic sensors. When cleaning, always
maintain a minimum distance of at least 10 centimetres.

PDC button
The PDC button is in the centre console switch cluster. The signal from the PDC button is transferred through
the K-CAN to the PDC control unit.
The PDC button is used to manually switch the Park Distance Control system on and off. When the PDC is
switched on, the function LED in the PDC button lights up.
If a fault develops in the PDC, the function LED in the PDC button flashes.
-
PDC control unit
The PDC control unit controls the ultrasonic sensors for transmitting ultrasonic impulses. The PDC control unit
also receives the digital signals from the individual ultrasonic sensors. By comparing the individual digital
signals, the PDC control unit calculates the minimum distance between the ultrasonic sensor and the object.
When an object is detected, an acoustic warning and a visual warning are given.

The PDC control unit is connected to various other control units via the bus systems:
-
Multi-audio system controller / Car Communication Computer
The multi-audio system controller (M-ASK) or Car Communication Computer (CCC) emits the PDC acoustic
warning through the mid-range loudspeakers.
