Tyre Pressure Control (Rdc) - BMW Motorrad R 1250 R Rider's Manual

164 ENGINEERING DETAILS
effectiveness of emergency
braking is ensured.
If the throttle is closed
(throttle grip position < 5 %)
while Dynamic Brake Control
is in action, the engine torque
requested by the ABS brake
system is restored.
If emergency braking
ceases and the rider still
has not changed the po-
sition of the throttle grip,
Dynamic Brake Control
steadily ramps engine torque
back to the rider's requested
level.
TYRE PRESSURE CONTROL
(RDC)
with tyre pressure control
(RDC) OE
Function
A sensor integrated into each
tyre measures the air tempera-
ture and the air pressure inside
the tyre and transmits this in-
formation to the control unit.
Each sensor has a centrifu-
gal-force tripswitch that does
not enable transmission of
the measured values until the
motorcycle has exceeded a
defined minimum speed for
the first time.
Minimum speed for
transmission of the RDC
measured values:
min 30 km/h
The display shows
each tyre until the tyre-pressure
signal is received for the first
time. The sensors continue to
transmit the measured-value
signals for some time after the
vehicle comes to a stop.
Time for transmission of
measured values after
vehicle comes to a stop:
min 15 min
An error message is issued if
wheels without sensors are fit-
ted to a vehicle equipped with
an RDC control unit.
Tyre pressure ranges
The RDC control unit differ-
entiates between three tyre-
pressure ranges, all of which
are parameterised for the mo-
torcycle:
Tyre pressure within permit-
ted tolerance.
Tyre pressure close to limit of
permitted tolerance.
Tyre pressure outside permit-
ted tolerance.
