  • Patent number: 10144432
    Abstract: Method for controlling the claw coupling of two gearbox elements initially rotating at different speeds when the driver or the box computer requests claw coupling, characterized in that, in a first phase, the difference in rotational speed of the rotary elements is brought by a regulator to a non-zero reference value without any translational movement of the rotary elements toward one another, and in that the movement of the rotary elements until they are claw-coupled occurs in a second phase that begins when the difference in rotational speed reaches its desired value, during which phase the difference perceived by the regulator is modulated by a factor (F) that is a function of the raw difference between the measured value and the reference value.

  • Patent number: 10083620
    Abstract: Methods, apparatuses, and non-transitory computer readable storage media for a smart tutorial that adapts are described. The smart tutorial may assist in the operation of a vehicle including generating a situational profile that includes driver identity data, vehicle state data, or extra-vehicular state data. The situational profile is compared to assistance profiles that include aggregate identity data, aggregate vehicular state data, or aggregate extra-vehicular state data. The assistance profiles correspond to assistance instructions. Based on the comparison, similarity values corresponding to the assistance profiles are generated based on the comparison between the situational profile and the assistance profiles. The greatest similarity value corresponds to the assistance profile that is most similar to the situational profile.
