Clutch overload protection (KÜS)
The clutch overload protection function (KÜS)
protects the clutch from thermal overload.
The clutch overload protection function
makes use of an arithmetic logic in the SMG
control unit that can calculate the thermal load
of the clutch based on the slip and contact
force.
In the first stage, the clutch overload
protection function reduces the slip at the
clutch. The customer would refer to this as a
"harsh gearshift".
The anti-jolt function is activated as a further
protection measure. As a result, the thermal
input at the clutch discs is reduced and the
driver's attention is drawn to the overload
situation.
If the temperature continues to increase, a
warning is triggered in order to repeatedly
draw the driver's attention to the overload
situation. Start-off in 2nd gear is automatically
inhibited when the gearbox warning is
triggered in order to minimise the clutch slip.
