Functions
Dynamic Stability Control MK60E5
DSC Additional Functions
Compared to the standard DSC features, the
MK60E5 in the E60 M5 has been upgraded
by the following additional functions:
• M Dynamic Mode (MDM)
• Brake readiness
• Dry braking
• Hill ascent assistant.
The following functions are not required on
the M5:
• Performance control (FLR)
• Soft stop
• Fading brake support (FBS)
• Dynamic traction control (DTC).
Operating modes of the MK60E5
In principle, the MK60E5 has 3 different
operating modes:
• DSC ON
• DSC OFF
• M Dynamic mode.
There is no DTC function in connection with
the M5. However, similar to DTC mode,
corresponding control thresholds are raised
by activating the MDM.
M Dynamic Mode can be activated only via the
M-Drive.
M Dynamic Mode (MDM)
MDM gives the performance-oriented driver
the option of driving the car with controlled
float angle and longitudinal slip without DSC
intervening. The control system intervenes
only when the physical limits are exceeded.
The control thresholds are not static but
rather, as the speed increases, they approach
the thresholds of DSC ON mode.
The stability control thresholds are identical as
from a speed of approx. 200 km/h in order not
to overtax the driver in the high speed range.
Brake readiness
The brake response time is shortened during
full brake application by applying the brake
pads to the discs while rapidly restricting the
throttle.
This function ensures that a pressure of
approx. 3 bar is applied for a period of up to
300 ms to the wheel brakes in order to apply
the brake pads already before the expected
application of the brakes. This function
facilitates even more rapid response of the
brakes. The function is active as from a speed
of 30 km/h.
Dry braking
The brake response characteristics are
improved in wet conditions by removing the
water film on the brake discs.
The DSC detects rain and therefore wet brake
discs through the permanent operation of the
windscreen wiper motor.
The dry braking function applies approx. 3 bar
hydraulic pressure to the wheel brakes under
these conditions. This procedure is repeated
every 2-3 km for a period of approx. 3 s when
the accelerator pedal is sufficiently depressed
(> 10 %), the vehicle speed is ≥ 90 km/h and
the brakes were not applied over the last 2-
3km.
