Patent number: 10393256Abstract: Desired is a control device for a vehicle drive apparatus capable of determining an engagement failure in an engagement device when shifting a transmission device to a neutral state and making the rotational speed of a driving force source reduced. In order to shift a transmission device from a state in which an object shift speed is established and the vehicle is traveling to a neutral state in which no shift speed is established in the transmission device (#02), when an object engagement device is disengaged while maintaining engagement of a non-object engagement device and the rotational speed of a driving force source (#04, #06) is made to be reduced, an engagement failure in the object engagement device (#02, #07) is determined based on a change in the rotational speed of an input member.Type: GrantFiled: March 30, 2016Date of Patent: August 27, 2019Assignee: AISIN AW CO., LTD.Inventor: Yuto Yuasa

Patent number: 10393257Abstract: A control apparatus includes a select lever, an inhibitor switch, a manual valve, a first SOL, a second SOL, and a controller. The controller controls the first SOL and the second SOL such that a hydraulic pressure is supplied to a first friction element and a second friction element when the inhibitor switch detects a D range. The controller determines that an operation position is at an intermediate position when operations of the first friction element and the second friction element are not detected. The controller determines that the first SOL has a failure when the operation of the first friction element is not detected.Type: GrantFiled: January 12, 2016Date of Patent: August 27, 2019Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Sadamu Fujiwara, Hideharu Yamamoto
