<p>A method is provided to control a drivetrain of a vehicle, especially a utility vehicle, wherein the drivetrain includes an engine with a cooling system. The cooling system includes a fan. The cooling system and the drivetrain are controlled by an electronic control unit (ECU). The ECU has access to a navigation system with topographic data. The method includes determining a topology of an upcoming route of the vehicle, estimating the load of the engine dependent of the topology of the upcoming route, estimating a temperature variation of the cooling system during the upcoming route, and controlling the drivetrain dependent on the estimated temperature variation, such that an actual temperature of the cooling system is kept below a temperature threshold value during the upcoming route of the vehicle. The temperature threshold value is dependent on a temperature at which said fan is activated.</p> |
