3 Series E92 335xi (N54) COUPE
> E90, E91, E92
As required by law, the brake lights are activated in the event of automatic braking when the Electronically
Controlled Deceleration function (ECD) is triggered by the ACC.
To do this, a signal must be sent from the DSC to the footwell module via the PT-CAN.
-
KOMBI: Instrument cluster
The DSC control unit actuates the indicator and warning lights for the individual DSC functions via the
instrument cluster (signal via CAN bus).
> E83
The instrument cluster is the data interface (= gateway) between:
•
PT-CAN
•
K-bus
-
EGS: Electronic gearbox control (vehicles with automatic transmission)
The transmission control (EGS) receives the wheel-speed signals via the PT-CAN.
The gearbox controller responds by adapting the gearshift characteristics for cornering and ascents. In addition,
the gearshift characteristics are adapted to winter conditions (high wheel slip).
Moreover, gearshifts are suppressed during DSC control.
-
CID and CON: Central Information Display and controller
The detailed texts for the Check-Control messages are shown in the Central Information Display (CID).
CID and controller are also used to initialise the Run Flat Indicator (RPA).
With xDrive an additional function can be activated to reduce speed when driving downhill: Hill descent control
(HDC)
-
TCU or ULF: Telephone control unit with GPS antenna
If the car is not fitted with a navigation system, the telephone control unit receives the converted wheel speed
signals from the front left and right wheels.
The telephone control unit uses these signals to pinpoint the car's position by dead reckoning.
-
GM: General module
> E83
The general module supplies input signals with respect to terminal control.
System functions
The dynamic stability control system (DSC) controls longitudinal and transverse dynamics by means of engine and
brake system intervention.
DSC 8Plus includes the following new functions.
-
Brake Standby through pre-tensioning of the brakes in an emergency
-
Brake disc drying on wet roads
-
Fading compensation
-
Soft stop when braking to standstill (not on BMW 3-Series all-wheel drive or E83)
-
Start-off assistant
DSC 8Plus includes the following familiar functions.
-
ABS: Anti-lock braking system
-
EBV: Electronic brake force distribution
-
CBC: Cornering brake control
