<p>A method (400) and control unit (115) for shifting gears of a transmission (113) in a vehicle (100). The method (400) comprises determining (401) that the rpm level of the vehicle engine (110) lies within an rpm range (210) for engaging a new gear, predicting (402), by simulating the shift of gears, what the lowest rpm (220) would be after a shift to the new gear were the shift to be performed, calculating (403) a threshold rpm (230) at which the vehicle engine (110) will generate a propulsive force corresponding to the running resistance of the vehicle, and increasing (404) the gear-shifting performance so that the predicted (402) lowest rpm (220) will equal or exceed the threshold rpm (230) so that the shift can be performed if the predicted (402) lowest rpm (220) is below the calculated (403) threshold rpm (230).</p> |
