Abstract
A method for controlling an automated clutch or an automated transmission or a drive unit in a vehicle is disclosed in which protective measures for the clutch and/or for the transmission and/or for a drive unit is provided by the control system. 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.
Claims9
A method for controlling an automated clutch or automated transmission or drive unit in a motor vehicle, where protective measures are provided by a control system for the clutch and/or for the transmission and/or for a drive unit which are undertaken depending on an obtained temperature of a specified vehicle component of the clutch or of the transmission or of the drive unit, whose cooling occurs by convection, characterized in that an air density in the environment of the vehicle and/or an altitude relative to standard elevation zero (sea level) at which the vehicle is moving and or an air mass flow around the vehicle component contributing to the cooling are taken into account when obtaining the temperature.
A device for controlling an automated clutch or automated transmission or drive unit in a vehicle which has the clutch, the transmission, the drive unit and at least one control device, where the control device is provided to control protective measures for the clutch and/or the transmission and/or for a drive unit, which are undertaken depending on an obtained temperature of a specified vehicle component of the clutch or of the transmission or of the drive unit, whose cooling occurs by convection, wherein an air density in the environment of the vehicle and/or an altitude relative to standard elevation zero (sea level) at which the vehicle is moving and or an air mass flow around the vehicle component contributing to the cooling is taken into account when obtaining the temperature.
