Abstract (en)

[origin: WO2016020590A1] A gearbox for a motor vehicle comprising at least one coupling means (213, 223, 233) for coupling a shaft (1000, 1001) to a pinion mounted about said shaft (1000, 1001), said coupling means (213, 223, 233) being movable in translation, a control cylinder (100) movable in rotation to control the translation of said coupling means (213, 223, 233), a means (610, 910) for monitoring the angular displacement of the cylinder (100), a means (700, 800, 900) for observing if the control cylinder (100) is at a predefined angular position (θ0) predefined to initialise said monitoring means (610, 910), and a means (600, 900) for controlling the rotation of the cylinder (100) until the fact that the cylinder (100) is in said predefined angular position (θ0) is observed, characterised in that the gearbox further comprises means (261, 262, 263, 900) for disengaging the coupling means (213, 223, 233) from the cylinder (100) during the implementation of said means (600, 900) for controlling the rotation of the cylinder (100) until the fact that the cylinder (100) is in said predefined angular position (θ0) is observed, and re-engaging said coupling means (213, 223, 233) in the cylinder (100) in order to engage a gear ratio.
