Abstract

The invention relates to a method for controlling a drive train (10) of a vehicle (1), wherein the drive train (10) comprises at least a clutch (12) and a transmission (13), wherein the clutch (12) is adapted to drive The transmission is connected to the propulsion unit (11). The method comprises the steps of: - estimating ( 105 ) an on-coming clutch temperature based at least on the on-coming travel route, and, if ( 106 ) the estimated on-coming clutch temperature is above a threshold (T), - in a critical heat mode The driveline (10) is controlled (107), wherein in this critical heat mode, the transmission (13) is controlled so that the increase in clutch temperature is lower compared to the normal driveline control mode.

Description

technical field [0001] The present invention relates to a method for controlling a drive train of a vehicle. The invention also relates to a computer program product, a computer readable medium and a control unit for carrying out the method. [0002] The present invention can be applied to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described with reference to a truck, the invention is not limited to this particular vehicle, but may also be used in other vehicles as described above. Background technique [0003] Vehicles, such as trucks, are typically provided with a clutch, which is arranged between the vehicle's propulsion unit and the transmission. When the clutch is actuated during starting and / or stopping of the vehicle and / or during shifting of the vehicle, the clutch slips and generates heat due to friction. Therefore, actuation of the clutch means heating of the clutch. If the clutch overheats, the clutch functi...
