System functions

PDC incorporates the following functions

1. Acoustic warnings
2. Visual warning with multi-audio system controller and Car Communication Computer
3. Check Control
4. System limits Acoustic warnings The acoustic warnings are emitted by: > E70 Mid-range loudspeaker with CHAMP, M-ASK or CCC If an object is detected by 2 ultrasonic sensors, the loudspeaker closest to the object is actuated. The mid-range loudspeakers can be actuated. (depending on the model concerned, the mid-range loudspeakers in the left/right front doors or left/right rear doors are actuated, for example) If an object is detected by the central ultrasonic sensors, the mid-range loudspeakers on the left and right-hand sides are actuated together. > E87, E90, E91, E92, E93 2 acoustic generators (1 front, 1 rear) with radio without audio system The PDC control unit directly actuates the acoustic generators (front/rear in vehicle interior). Within the acoustic generator, the control signal is transformed to approx. 48 volts. This voltage excites a piezo ceramic element that together with the resonator (housing) generates a warning tone. Up to 09/2006, the tone is in the frequency range of approximately 1 kHz. From 09/2006 the tone is in the frequency range of approximately 1.5 kHz (front) or 1.0 kHz (rear). Mid-range loudspeaker with RAD 2, M-ASK or CCC If an object is detected by 2 ultrasonic sensors, the loudspeaker closest to the object is actuated. The mid-range loudspeakers can be actuated. (e.g. the mid-range loudspeakers in the front doors, left/right, in the rear shelf, left/right, in the rear doors, left/right, in the rear shelf, left/right or in the rear side trim, left/right are actuated, depending on the vehicle model.) If an object is detected by the central ultrasonic sensors, the mid-range loudspeakers on the left and right-hand sides are actuated together. > R56 1 acoustic generator (rear) with Radio Wave The PDC control unit directly actuates the acoustic generators (in rear of vehicle interior). Within the acoustic generator, the control signal is transformed to approx. 48 volts. This voltage excites a piezo ceramic element that together with the resonator (housing) generates a warning tone. The tone is in the frequency range of approximately 1 kHz. Mid-range loudspeakers with Radio Wave CD, Radio Boost CD or CCC If an object is detected by 2 ultrasonic sensors, the loudspeaker closest to the object is actuated. The mid-range loudspeaker on the left/right can be actuated. If an object is detected by the central ultrasonic sensors, the mid-range loudspeakers on the left and right-hand sides are actuated together. The distance to the object determines the tone sequence for the acoustic warning (the smaller the distance, the faster the tone sequence). A distance of less than approx. 25 centimeters is indicated by a continuous tone. The continuous tone is emitted alternately from the front and the rear. If the vehicle moves away from the object, the warning tone will be cancelled when the distance increases by more than 10 centimeters. Effective range for acoustic warnings: approx. 60 centimeters for the ultrasonic sensors at the two corners of the front bumper approx. 70 centimeters for the two middle ultrasonic sensors in the front bumper approx. 60 centimeters for the ultrasonic sensors at the two corners of the rear bumper approx. 150 centimeters for the two middle ultrasonic sensors in the rear bumper

Optical warning with multimedia platform or multi audio system controller or Car Communication Computer

The visual PDC warnings are given in the Central Information Display (CID). This is subject to the PDC display in the CID being active.

The visual warnings are given earlier than the acoustic warnings.

The effective range is approx. 2.5 meters at the front and rear.

The graphic display is shown on the CID. The PDC control unit supplies the distance between the ultrasonic sensor and the object detected via the K-CAN.

The PDC display on the CID is an overhead view of the vehicle with the effective range of the ultrasonic sensors.

The distance to objects detected is shown in the colors of traffic lights

1. Distance between 200 (250) and 101 centimeters: green
2. Distance between 100 an 51 centimeters: yellow
3. Distance less than 50 centimeters: Red

The PDC display appears as soon as the PDC is switched on (manually or automatically). The PDC display overrides other displays in the CID. When the PDC is switched off again, the previous display automatically appears again in the Central Information Display.

Check Control

If a fault should develop in the PDC, the function LED in the PDC button will flash with a frequency of 2 Hz.

In this situation, PDC cannot be switched on.

At the same time, a Check-Control message is displayed in the following form

1. Symbol in the LCD display in the instrument cluster
2. The following text appears in the status line of the Central Information Display: "PDC failure!" In the menu "BMW Service", the following text can be called up in the submenu "Check-Control messages": "Park Distance Control No acoustic warning available for Park Distance Control PDC. Have the problem checked by BMW Service as soon as possible." If a fault memory entry is recorded, the kilometer reading and the outside temperature are recorded along with the type of fault.

System limits

During operation, the following system functions, which require explanation, can occur due to the limits of the functional range (for the driver)

1. Under the following conditions, it could happen that the PDC gives a warning, even though there is no obstacle within the effective range: Ultrasonic sensor incorrectly located in its bracket Heavy rainfall Ultrasonic sensors covered in snow Exhaust gases Echo pulses caused by ground, e.g. extremely coarse road surface or high grass Very smooth walls in large, enclosed, rectangular spaces, e.g. in underground car parks (interference from previously reflected echo pulses) Protective cap for trailer coupling ball head incorrectly seated or objects being transported protruding into the effective range of the ultrasonic sensors.
2. Under the following conditions, the PDC may not recognize an obstacle that is present: Objects close to the ground (no reflection) Objects with corners and sharp edges (no reflection) If you drive alongside a wall for more than 3 seconds, the acoustic warning will be deactivated. Here, the distance must be greater than the effective range for the continuous tone (approx. 25 centimeters). As soon as the distance drops below 25 centimeters, the continuous tone will sound again. If the vehicle approaches an object too fast Starting up and moving away too quickly while PDC is starting

Conditions for switching on and off

PDC is switched on under the following conditions

1. PDC button pressed (PDC switched on manually), option 508 only
2. Reverse gear engaged (PDC switched on automatically)

PDC is switched off under the following conditions

1. Reverse gear disengaged, option 507 only
2. PDC button pressed (PDC switched off manually), option 508 only
3. Ignition switched off (PDC switched off automatically
4. After driving approx. 50 meters
5. After exceeding a speed of 30 km/h

When towing a trailer or driving with a rear carrier rack, the acoustic and visual warnings for the rear bumper are deactivated by the trailer module (AHM).

The trailer or rear carrier rack must be electrically connected.

Japanese national version

So long as reverse gear is engaged, an acoustic signal (reversing gong) is given via the acoustic generator or the mid range loudspeaker.

The reversing gong is deactivated immediately if the PDC detects an object in the effective range and emits its own acoustic warning.

Subject to change.
