Abstract
Method for restoration of the drive torque during a change of gear, wherein the clutch is closed in order to adjust the angular speed of the drive shaft to match the angular speed of the primary shaft of the gearbox; when the angular speed of the drive shaft is close to the angular speed of the primary shaft of the gearbox, a reference profile is generated for the angular speed of the drive shaft, and the drive torque generated by the engine is controlled in order to make the angular speed of the drive shaft follow the reference profile, which has a final portion which is substantially tangent to the angular speed of the primary shaft of the gearbox.
