Method to control a drivetrain (1) of a vehicle, wherein said drivetrain (1) at least comprises a combustion engine (E), a conventional transmission (T), a main clutch (C), a hydraulic transmission system (hT), a first axle (2) with a first wheel pair (3) and a second axle (4) with a second wheel pair (5), wherein said hydraulic transmission system (hT) at least comprises a pump, and said first wheel pair (3) is driven by said combustion engine (E) over said conventional transmission (T), and said second wheel pair (5) is driven by said combustion engine (E) over said hydraulic transmission system (hT), wherein said pump of the hydraulic transmission system (hT) is driven directly by said combustion engine (T), said method is performed during driving of said vehicle, wherein : - a gear change is initialised in said conventional transmission (T), whereby - said pump is controlled, such that load torque (LTh) from said pump on the combustion engine (E) is increased, wherein said load torque (LTh) increase on the combustion engine (E) caused by the pump at least partially replaces a load torque (LTt) decrease caused by said gear change. |
