Method for controlling the synchronization of a pinion (6) rotating on a primary shaft driven by a traction machine of the vehicle and rotationally connected to a secondary shaft of a parallel shaft gearbox that has no synchromesh mechanism, by sending to the traction machine, before the coupling of the pinion to the primary shaft, a torque command (T1 ref) which is dependent on a torque signal (T1 calc) calculated to minimize the discrepancy (σ) between the primary speed (ω1) and the secondary speed (ω2) multiplied by the reduction ratio (K) between these two shafts, characterized in that the calculated torque (T1 calc) is corrected by the acceleration of the secondary shaft (θ) in order to construct an intermediate signal (T*1) that takes account of the energy supplied by the traction machine in order to minimize the speed discrepancy (σ). |
