Abstract
The invention relates to a method for controlling a driveline (10) of a vehicle (1), wherein the driveline (10) at least comprise a clutch (12) and a transmission (13), where the clutch (12) is adapted to connect the transmission to an propulsion unit (11). The method comprises the steps of;—estimating (105) an upcoming clutch temperature at least dependent on an imminent drive route, and if (106) the estimated upcoming clutch temperature is above a threshold value (T);—controlling (107) the driveline (10) in a critical heat mode, wherein in the critical heat mode the transmission (13) is controlled such that a clutch temperature increase is lower in comparison to a normal driveline control mode.
Claims15
A method for controlling a driveline of a vehicle, wherein the driveline at least comprises a clutch and a transmission, where the clutch is adapted to connect and disconnect the transmission to a propulsion unit, wherein
- the method;
- estimating an upcoming clutch temperature at least dependent on an imminent drive route,
- and when the estimated upcoming clutch temperature is above a threshold value;
- controlling the driveline in a critical heat mode, wherein in the critical heat mode the transmission is controlled such that a clutch temperature increase is lower in comparison to a normal driveline control mode.
