<p>The invention concerns a device for controlling gear shifting in a countershaft transmission (1) of a motor vehicle (5) with a hydraulically operated clutch (2) located in or on the transmission (1) and operated in conjunction with a gear shift device (11). When the clutch (2) is disengaged, the speed (n1) of the engine (4) is controlled by an engine control device (3) in such a way that, just before the clutch is engaged, the primary shaft (22) always has a higher speed than the speed (n2) of the secondary shaft (23), so that, when the engine is coupled in, it is always braked as in traction shifting.</p> |
