Abstract (en)

[origin: WO2011058264A1] In order to couple an electrical machine to the driving wheels of a vehicle when the vehicle is at a standstill, the method comprises two stages (54, 55) which are activated in parallel at the instigation of a coupling request: - a stage (54) of translationally bringing two clutch dogs closer together along a common axis of rotation, an upstream dog rotating as one with the electrical machine and a downstream dog rotating as one with the driving wheels; and a stage (55) of slaving the torque of the electrical machine to a set dog-coupling torque which starts at a zero value at the moment of the coupling request and which progressively increases, remaining below an electrical machine start-up value for long enough for the two clutch dogs to be brought translationally closer together into a position which the tops of the teeth of the two clutch dogs are coplanar, and exceeding said start-up value after said sufficient duration has elapsed.
