Abstract
(EN)
The present invention is configured such that when the rotation of an engine (1) is stopped, the control of an electric oil pump (70B) driven by an electric motor (E) is switched from a flow rate control, in which a discharge flow rate is controlled to be a target flow rate, into a current control, in which a command current value output to the electric motor (E) is controlled to be a target value, and the command current value with which the current control is being performed is set to a current value (command value A) smaller than the value with which a forward clutch (31), at which an engaging capacity is generated according to the supplied amount of working oil, assumes a power transmission state.
(FR)
La présente invention est conçue de telle sorte que, lorsque la rotation d'un moteur (1) est arrêtée, la commande d'une pompe à huile électrique (70B) entraînée par un moteur électrique (E) passe d'une commande de débit, dans laquelle un débit d'évacuation est commandé pour être un débit cible, à une commande de courant, dans laquelle une valeur de courant d'instruction délivrée au moteur électrique (E) est commandée pour être une valeur cible, et la valeur de courant d'instruction avec laquelle la commande de courant est exécutée est réglée à une valeur de courant (valeur d'instruction A) inférieure à la valeur avec laquelle un embrayage vers l'avant (31), auquel une capacité de mise en prise est générée en fonction de la quantité d'huile de travail apportée, adopte un état de transmission de puissance.
(JA)
エンジン(1)の回転が停止しているとき、電動モータ(E)により駆動される電動オイルポンプ(70B)の制御を、吐出流量が目標流量となるように制御する流量制御から電動モータ(E)に出力する指示電流値を目標値に制御する電流制御に切り替えると共に、電流制御の実行中の指示電流値を、作動油の供給量に応じて締結容量が生じる前進クラッチ(31)が動力伝達状態になる値未満の電流値(指示値A)に設定する構成とした。
