<p>An engine (10, fig 1) of a motor vehicle (5) is connected to a manual gearbox (11) by a manual clutch (18). A Method of controlling the engine during a manual gearshift comprises in step 10 monitoring a state of, for example, an ignition switch (17), in step 20 it is determined by a position of a clutch pedal (25) whether a gear change has been initiated, in step 30 the type of gear change is established by using output from an accelerator pedal (24) in combination with a gear position sensor (12), in step 40 a target engine speed NTGT is determined, in step 50 it is ascertained whether the target engine speed NTGT is greater than an engine speed NDEM demanded by a driver, if yes the method moves to step 60 where the engine speed NDEM is driven towards the target engine speed NTGT and in step 70 with the engine speed NDEM at the target engine speed NTGT where it is held until confirmed that a selected gear is engaged. The method uses an electronic controller to assist the driver with gear changes which may be of different types such as accelerating upshifts/downshifts and/or decelerating upshifts/downshifts.</p> |
