    摘要: Method for learning the neutral position of a gear shift actuator (1) with sliding gear (2) motorised between two opposed engaging pinions (3, 4), comprising a control element (5) that is position-regulated by the drive motor thereof, which acts on a mechanical movement assembly of the slide gear provided with an assistance system (7) having a spring, capable of firstly accumulating energy when the teeth of the sliding gear come to abut against those of the pinion to be engaged in order to shift the gears and then secondly of restoring this energy by relaxing in order to assist the engagement of the teeth of the sliding gear between those of said pinion, characterised in that the neutral position of the actuator (1) is determined by identifying the positions of the control element (2) at the time when the teeth of the sliding gear (2a) come to abut against those of each of the two pinions (3a, 4a), by observing the resistant torque on the control element (5) during movement of the sliding gear (2) towards the pinions (3, 4).

    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.

    摘要: The invention relates to a method according to which stator current set points are generated on the basis of an estimation of a selectively determined rotor magnetic flux, according to the operating conditions of the machine, depending on the operating temperature of the rotor of the machine and further depending on the measured values of the current (I
    d , I
    q ) and the excitation voltage (V
    q ) of the rotor and the speed of rotation of the rotating magnetic field (ω
    r ) generated by the rotor, the stator current set points being generated on the basis of the estimated magnetic flux.
