The first hydraulic control section forms an oil passage so as to supply oil to a friction fastening element if the select lever is in the drive range or between the drive range and a non-drive range, and forms an oil passage so as to discharge the oil from the friction fastening element if the select lever is in the non-drive range. After it is determined that there is an abnormality in the signal of a range signal output section, the abnormality determining section cancels the abnormality determination if only a drive range signal is output from the range signal output section, and maintains the abnormality determination if only a non-drive range signal is output. The second hydraulic control section forms an oil passage so as to supply oil to the friction fastening element during the abnormality determination or if only the drive range signal is being output, and forms an oil passage so as to discharge the oil from the friction fastening element before the abnormality determination or if only the non-drive range signal is being output.

Selon l'invention, une première unité de commande hydraulique forme un passage d'huile destiné à alimenter en huile un élément de fixation à friction lorsqu'un levier de sélection se trouve entre une plage de déplacement et une plage de non-déplacement, et forme un passage d'huile destiné à la décharge d'huile provenant de l'élément de fixation à friction lorsque le levier de sélection se trouve dans la plage de non-déplacement. Après détermination du dysfonctionnement d'un signal d'une unité d'émission en sortie de signal de plage, une unité de détermination de dysfonctionnement annule cette détermination en tant que dysfonctionnement lorsqu'est émis en sortie uniquement un signal de plage de déplacement provenant de l'unité d'émission en sortie de signal de plage, et maintient cette détermination en tant que dysfonctionnement lorsqu'est émis en sortie uniquement un signal de plage de non-déplacement. Une seconde unité de commande hydraulique forme un trajet d'huile destiné à alimenter en huile l'élément de fixation à friction lorsqu'il y a détermination de dysfonctionnement, ou lorsqu'est émis en sortie uniquement un signal de plage de déplacement, et forme un trajet d'huile destiné à la décharge d'huile provenant de l'élément de fixation avant détermination de dysfonctionnement, ou lorsqu'est émis en sortie uniquement un signal de plage de non-déplacement.

 第1油圧制御部は、セレクトレバーが走行レンジおよび走行レンジと非走行レンジとの間にある場合には摩擦締結要素に油を供給するように油路を形成し、非走行レンジにある場合には摩擦締結要素から油を排出するように油路を形成し、異常判定部は、レンジ信号出力部の信号が異常であると判定した後に、レンジ信号出力部から走行レンジ信号のみが出力された場合には異常判定を取り消し、非走行レンジ信号のみが出力された場合には異常判定を維持し、第2油圧制御部は、異常判定中、または走行レンジ信号のみが出力されている場合には摩擦締結要素の油を供給するように油路を形成し、異常判定前、または非走行レンジ信号のみが出力されている場合には摩擦締結要素の油を排出するように油路を形成する。
