M-ASK or CCC and CID: Multi-audio system controller/Car Communication Computer and Central Information
Display
For the instrument cluster, the M-ASK or CCC serves as the interface to the CID. Amongst other things, the CID
displays detailed information about the Check-Control messages. To back up the Check-Control message, the
M-ASK /CCC emit audible warnings through the loudspeakers (depending on national version). The instrument
cluster controls these warnings by means of the K-CAN.
System functions
The system functions of "cruise control with brake function" and "Active Cruise Control" are described below.
Option "Cruise control with brake function"
-
Cruise control
Cruise control has the following subfunctions:
•
Cruise control system
•
Limited lateral acceleration when cornering (up to max. 4.0 m/s
2
)
Depending on the driving situation, the LDM control unit reports to the DME or DDE or the DSC as follows:
•
DME or DDE: Accelerate
•
DSC: Brake
>
E92 from 06/2006 and
E90, E91 from 09/2006 and
E93 from 12/2006
The LDM control unit is no longer fitted on vehicles with option 544 "Cruise control with brake function".
Because of a software modification in the DSC control unit (DSC Mk60E5), the DSC control unit assumes
control of the functions of the LDM control unit.
Option "Active Cruise Control"
-
Monitor object ahead
-
Cruise control
-
Lens heating
-
Low-voltage cutout and high-voltage protection for ACC sensor
-
Self-diagnosis and compensation for minor horizontal adjustments
-
System limits
Monitor object ahead
Objects are all vehicles in the same lane. The vehicles on other lanes are of no interest for Active Cruise
Control.
In the same lane, the vehicle immediately ahead is selected as the object.
With the calculated expected same lane, the lateral deviation of each monitored object to the same lane can be
determined.
The radar waves received cannot distinguish between animals, vehicles and traffic signs. In order to prevent
incorrect reactions, stationary objects and traffic in the other direction are ignored in the distance control.
