<p>A method (300) and control unit (115) for shifting gears of a transmission (113) in a vehicle (100). The method (300) comprises determining (301) that the rpm level of the vehicle engine (110) lies within an rpm range (210) for engaging a new gear, predicting (302), 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 (303) a threshold rpm (230) at which the vehicle engine (110) will generate a propulsive force corresponding to the running resistance of the vehicle, and preventing (304) a shift to the new gear when the predicted (302) lowest rpm (220) is below the calculated (303) threshold rpm (230).</p> |
