Abstract:
A method for restoration of drive torque during a change of gear, wherein a clutch is closed in order to adjust an angular speed (&ohgr;m) of a drive shaft to match an angular speed (&ohgr;l) of a primary shaft of a gearbox; the method comprising generating a reference profile (&ohgr;mrif) for said angular speed (&ohgr;m) of said drive shaft, and controlling an engine, in order to make said angular speed (&ohgr;m) of said drive shaft follow said reference profile (&ohgr;mrif); andwherein, in a predetermined position (x*), said clutch transmits constant torque (Tcl*) which is substantially equal to a drive torque (T*) supplied by said engine immediately before change of gear.
