  • Patent number: 11428316
    Abstract: The invention provides an engagement method for engaging a first gear element with a second gear element, at least the second gear element being mounted to move between a meshing position and a disengaged position by means of an actuator. The engagement method including a step of driving at least one of the gear elements in rotation so as to establish a non-zero difference in speed of rotation between said gear elements, and a step of controlling the actuator to perform the following in succession: moving at least the second gear element towards the meshing position; on detecting contact between the gear elements, stopping the movement of the second gear element; and on detecting an ideal angular position for engaging said gear elements, moving the second gear element as quickly as possible into the meshing position.

  • Patent number: 11231088
    Abstract: A method for engaging a first gear element with a second gear element is provided. The second gear element is mounted to be mobile between a meshing position and a position of disengagement using an actuator. The method includes driving one or more of the first and second gear elements in rotation to form a non-zero rotation speed difference between the first and second gear elements and controlling the actuator to successively displace the second gear element to the meshing position, and when an intermediate position of the second gear element is detected, stop the displacement of the second gear element, and when an angular position of engagement of the first and second gear elements is detected, displace the second gear element to the meshing position.
