The protective measures include measures against overheating or wear. When measuring temperature, allowance is made for the air density in the vehicle environment or altitude as compared to sea level.

Method for controlling an automated clutch or automated transmission or a drive unit in a vehicle

The invention relates to a friction clutch in a motor vehicle, comprising a clutch bell housing (), at least one air inlet duct () arranged on the clutch bell housing for cooling the clutch bell housing, at least one air outlet duct () arranged on the clutch bell housing, and at least one temperature sensor (). The invention further relates to a method for determining a clutch temperature of a friction clutch.

Friction clutch

A process for controlling a drive train with an internal combustion engine, a transmission and an automatically actuated brake system. In the event of a defect of the transmission, retardation is effected by means of the automatically actuated brake system in order to avoid impermissibly high speeds in the drive train.
