<p>Method for synchronizing a gear on a parallel-shafts vehicle gearbox shaft comprising at least one primary shaft connected to a power source, one secondary shaft driven by the primary shaft to transmit the driving torque to the wheels over various transmission ratios, and at least one means of coupling a gear to its shaft in order to engage a transmission ratio without mechanical synchromesh members, characterized in that the power source is made to operate in such a way as to produce the signal commanding the reference torque (T1 ref ), equal to the minimum torque that can be transmitted in order to minimize the discrepancy (omega 2 K -omega 1) between the primary speed (omega 1) and the secondary speed (omega2) multiplied by the reduction ratio (K), when the relevant gear is coupled to its shaft, characterized in that the control signal is given by the sum (K w .K.omega 2 - K s .omega 1 + T 1 in t), where ( Tau 1 int ) is a term derived by integrating the primary speed (omega1).</p> |
