A method and an arrangement for controlling the speed of an engine (10) of a heavy vehicle during gear changing in a mechanical gearbox (12, 13, 14) in cases where a manually operable clutch (11) is incorporated in the driveline between the engine and the gearbox are distinguished by the fact: that running parameter data of the vehicle are observed and recorded, that breaking of the driveline upon disengagement of the clutch (11) is detected and a first signal indicative thereof is generated, that a gear signal indicating the intended gear position is generated, that a desired engine speed intended to prevail upon completion of the gear change is determined, in response to the first signal, on the basis of said running parameter data and the gear signal, and that a control signal is generated which acts upon the engine control system so that the engine speed is adjusted towards said desired speed. |
