    摘要: Method for controlling the declutching of a sliding gear (1) of the gearbox of a vehicle with dog clutches (1a), rotatably attached to a shaft of said gearbox on which it can move axially under the control of a powered transition actuator between a neutral declutched position and at least one position of engagement on a hybrid gear where it is engaged on a pinion rendered rigidly connected to the shaft in order to transmit to the wheels of the vehicle, in a cumulative or non-cumulative manner, the torque received from at least two distinct power sources, characterised in that it comprises the following steps: - application of a zero torque request on all the power sources of the vehicle, - application of a declutching instruction on the sliding gear, - in the absence of rapid declutching, estimating the resistance torque (C
    r ) on the dog clutches (1a) of the sliding gear, - calculating the residual torque (C
    res ) on the dog clutches as a function of the calculated resistance torque and the anti-disengagement angle of same, - cancelling the residual torque (C
    res ) by application of an opposite torque (C1, C2) on the sliding gear, - declutching.
