Abstract The present invention is equipped with: a coasting-stop control unit that stops the drive power source and performs a coasting stop when a first friction element is engaged and a second friction element is disengaged, when a vehicle is travelling; and a friction element control unit that controls the engagement of the first friction element and the engagement of the second friction element. The friction element control unit begins the supply of hydraulic pressure to the second friction element in the interval between the issuing of the command from the coasting-stop control unit to stop the drive power source and the stopping of the rotation of the hydraulic pressure source. L'invention concerne : une unité de commande d'arrêt de marche en roue libre qui arrête la source d'alimentation d'entraînement et effectue un arrêt de marche en roue libre lorsqu'un premier élément de friction est embrayé et un deuxième élément de friction est débrayé, pendant le déplacement d'un véhicule ; ainsi qu'une unité de commande d'éléments de friction qui commande l'embrayage du premier et du deuxième élément de friction. Cette dernière démarre l'alimentation en pression hydraulique du deuxième élément de friction dans l'intervalle entre l'émission de la commande provenant de l'unité de commande d'arrêt de marche en roue libre visant à arrêter la source d'alimentation d'entraînement et l'arrêt de la rotation de la source de pression hydraulique.
