Abstract

L'invention propose un procédé de commande du verrouillage en position de stationnement d'une transmission (T) qui comporte une roue dentée de stationnement (22), un doigt (24) de blocage en rotation de la roue de stationnement (22), un actionneur du doigt (24) de blocage entre ses positions active et passive, un moteur électrique (ME) qui est lié à la roue dentée de stationnement (22) pour lui appliquer un couple, caractérisé en ce qu'il comporte une étape de détermination du couple de gravité (Cg) appliqué au véhicule et qui résulte de la masse (M) du véhicule et de la pente (A) du terrain ; et lorsque le couple de gravité (Cg) est supérieure à une valeur de seuil, une étape de commande du moteur électrique (ME) pour appliquer à la roue dentée de stationnement (22) un couple (Ca) d'assistance au déblocage pour réduire les efforts résistant appliqués au doigt (24) de blocage et qui résultent dudit couple de gravité (Cg).The invention proposes a method for controlling the locking in parking position of a transmission (T) which comprises a parking gear (22), a finger (24) for locking the parking wheel (22) in rotation, a finger actuator (24) for locking between its active and passive positions, an electric motor (ME) which is connected to the parking gear (22) to apply a torque to it, characterized in that it comprises a step of determination of the gravity torque (Cg) applied to the vehicle resulting from the mass (M) of the vehicle and the slope (A) of the terrain; and when the gravity torque (Cg) is greater than a threshold value, a step of controlling the electric motor (ME) for applying to the parking gear (22) an unlocking assist torque (Ca) to reduce the resistant forces applied to the locking finger (24) and which result from said gravity torque (Cg).
