Starting strategy for a vehicle with an automated clutch and / or with an automated transmission and clutch control device for performing a starting strategy

摘要

Starting strategy for a vehicle with an automated clutch and / or with an automated transmission, wherein a thermal overload protection for the clutch is realized in which a clutch torque to be transmitted by the clutch is determined during start-up at least in dependence on the clutch temperature, wherein the clutch torque in Depending on the engine speed (n) and the clutch temperature (θ) is determined, wherein as approach characteristic (g) the following function is selected: whereeif (ne): standard starting torque ( θ): clutch temperature-dependent factor, characterized in that in the Anfahrkennfeld (g) with increasing clutch temperature (θ) the standard starting torque (f) is increased in order to shorten the start, wherein the clutch temperature dependent factor (k) is selected such that a monotone increasing course with rising clutch temperature (θ) is achieved, the factor (k) maintaining the value 1 up to a coupling temperature (θ) of 150 ° C, the factor (k) then increasing linearly to the maximum value 2.5 and decreasing this value Clutch temperature (θ) of 300 ° C maintains.
