Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION AND HYDRAULIC PRESSURE CONTROL METHOD THEREFOR
(FR) TRANSMISSION À VARIATION CONTINUE ET PROCÉDÉ DE COMMANDE DE PRESSION HYDRAULIQUE POUR CELLE-CI
(JA) 無段変速機及びその油圧制御方法
Abstract: front page image
(EN)In the present invention, a transmission controller performs the following: detection of the rotation speed of an input shaft; calculation, on the basis of the rate of change of the detected rotation speed, the inertia torque input to a continuously variable transmission; determination of positive inertia torque by extracting the positive portion from the calculated inertia torque; and correction of pulley pressure on the basis of the extracted positive inertia torque.
(FR)La présente invention porte sur une unité de commande de transmission qui exécute ce qui suit : la détection de la vitesse de rotation d'un arbre d'entrée ; le calcul, sur la base du taux de variation de la vitesse de rotation détectée, du couple d'inertie appliqué à une transmission à variation continue ; la détermination d'un couple d'inertie positif par extraction de la partie positive du couple d'inertie calculé ; et la correction de la pression sur la poulie, sur la base du couple d'inertie positive extrait.
(JA) 変速機コントローラは、入力軸の回転速度を検出し、検出された回転速度の変化率に基づき無段変速機に入力されるイナーシャトルクを演算し、演算されたイナーシャトルクから正の部分を抽出して正イナーシャトルクを求め、抽出された正イナーシャトルクに基づいてプーリ圧を補正する。
