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.
