GF54.65-P-2006GZJ Parallel Parking, Function
- with CODE (218) Backup camera
- except CODE (849) Spare wheel holder/spare wheel
Parallel parking mode (parallel parking)
In this mode, the driver receives visual and acoustic support when parking parallel to the direction of travel.
Function requirements:
^ Circuit 15 ON
^ Reverse gear engaged (DIRECT SELECT gear selector switch "R")
^ Parallel parking mode selected via COMAND operating, display and controller unit (A40/3)
The "Parallel Parking Mode" procedure consists of two successive steering maneuvers "first steering turn" and "second steering turn". The first involves steering into the parking space and the second involves the subsequent countersteering, to maneuver the vehicle into a straight position in the parking space parallel to the edge of the road.
The driver receives visual and acoustic support during all individual steps. The backup camera system (RFK) reacts dynamically to each reaction of the driver and adapts the information to the respective situation.
The acoustic information and warning messages are generated in the backup camera control unit and output via the front intercom system speaker.
Voice output is only in Japanese. The warning messages in the display of the COMAND operating, display and controller unit can either be displayed in English or Japanese.
Component Identification:
Start position
Before the driver activates the backup camera system (RFK), he/ she must position the vehicle so that it is parallel to the vehicle parked in front at a distance of one meter. In addition, the driver seat of the vehicle parked in front should be at the level of the rear axle of the driver's own vehicle.
The driver starts the backup camera system (RFK) by engaging reverse gear. The display of the COMAND operating, display and controller unit shows the driver a current image of the area to the rear of the vehicle with two vertical extension lines superimposed on it.
These two vertical extension lines represent the rear end of the vehicle parked in front.
If this is not the case then the driver must first reverse the vehicle until one of the extension lines contacts the rear end of the vehicle and an acoustic message sounds.
The vehicle is then stopped and this is again acknowledged by an acoustic signal.
Component Identification:
Determining final parking position
Once the start position for parking is defined, then the desired parking position must be set. To do so, the driver must first turn the steering wheel (with vehicle stationary).
A parking frame is then displayed on the COMAND operating, display and controller unit, which the driver must use to set the target position. This parking frame turns in ratio to the steering angle, i.e. with the aid of the steering wheel the driver can define the position of the parking frame and thus the final parking position. The driver can also use the parking frame to determine whether the parking space is suitable for his/her vehicle.
Once the driver has defined the parking position with the aid of the parking frame, the backup camera control unit (N66/2) then uses the collated data to define the parking position and the required steering angle for the subsequent first individual step (first steering wheel turn).
The color of the parking frame must be green, if the parking space is to be successfully entered with the set steering angle. If the parking frame is colored red, then the steering angle must be continually adapted until the parking frame turns green.
Component Identification:
First steering angle
Once the parking position has been defined, the driver moves the vehicle backwards. During this phase the driver must maintain the previously defined steering angle. During the entire maneuver, the backup camera system (RFK) monitors the actual vehicle movement, the steering angle and the wheel speed in order to be able to react appropriately to the respective situation with information messages or warnings. These information messages or warnings are conveyed to the driver as display texts an acoustically by the backup camera system (RFK).
As soon as the vehicle approaches the edge of the road, a guide line appears in the display.
This guide line can be used by the driver to determine when he/ she should initiate the next individual step. As soon as the guide line virtually contacts the edge of the road and an acoustic message sounds, the driver stops the vehicle, which is also acoustically acknowledged to the driver by the backup camera system (RFK). The driver then turns the steering wheel to the limit stop in the opposite direction.
To avoid a situation whereby the driver relies solely on the display and thus no longer pays attention to the immediate traffic situation, extension lines are not displayed in the parking space during the first individual step..
Second steering angle
As soon as the steering wheel is at the limit stop (acknowledged acoustically), distance extension lines like those from back-in parking mode appear in the display again. These lines can be used by the driver to maneuver the vehicle such that the best parking position is achieved.
For approaching a curb (for example), the driver also has the option of switching to the passenger-side outside mirror backup camera (B84/6) via the menu in the COMAND operating, display and controller unit. The extension lines displayed help the driver to maneuver near enough to the edge.
Fault messages
If there is no signal from the backup camera (B84/3) or from the passenger-side outside mirror backup camera or if other CAN signals are faulty, there is no display in the COMAND operating, display and controller unit.
The fault message is filed in the memory of the backup camera control unit.
