  • Publication number: 20150240938
    Abstract: A transmission controller determines whether a vehicle is going to stop based on a driving condition of the vehicle. When it is determined that the vehicle is going to stop, a lock mechanism is placed in an unlocked state through a supply of an OFF pressure to an OFF pressure piston chamber even if a D mode is selected by a select switch.

  • Publication number: 20150217773
    Abstract: A control unit performs a engaging control, which supplies an ON pressure to a engaging-side oil chamber to set a lock mechanism to a locked state and then decreases the hydraulic pressure of the engaging-side oil chamber, when a running mode is selected, and performs a releasing control, which supplies an OFF pressure to a release-side oil chamber to set the lock mechanism to an unlocked state and then decreases the hydraulic pressure of the release-side oil chamber, when a non-running mode is selected. The control unit supplies the OFF pressure to the release-side oil chamber when the stop of the operation of the driving force source is notified, and allows stopping the operation of the driving force source when the lock mechanism becomes the unlocked state afterward.

  • Publication number: 20150141189
    Abstract: In friction engagement device having forward clutch 5 and clutch operation pack 6 controlling engagement/disengagement operation of the forward clutch 5, the clutch operation pack 6 has hydraulic piston 61, engagement pressure piston chamber 62, snap ring 64, diaphragm spring 65 and ball lock mechanism BL. The diaphragm spring 65 provides biasing engagement force to the forward clutch 5 at a clutch side of the hydraulic piston 61. The ball lock mechanism BL restrains movement, in a disengagement direction, of the hydraulic piston 61 at a position where the forward clutch 5 is in an engagement state by the biasing engagement force by exerting ON pressure on the engagement pressure piston chamber 62, and after restraining the movement of the hydraulic piston 61, maintains the restraint of the disengagement direction movement of the hydraulic piston 61 even when the ON pressure of the engagement pressure piston chamber 62 is drawn.

  • Patent number: 8875863
    Abstract: A multi-disc frictional engagement mechanism includes a plurality of driven plates and drive plates, a hydraulic piston, a spring which comes into contact with a pressure receiving portion of the hydraulic piston, an oil chamber which causes a hydraulic pressure to act on the pressure receiving portion, and a lock mechanism which restricts a movement of the hydraulic piston in a coupling direction toward the driven plates and the drive plates in a state where the hydraulic pressure is supplied to the oil chamber, the spring is compressed by the pressure receiving portion and the driven plates and the drive plates are not coupled.

  • Publication number: 20140287686
    Abstract: Disclosed is a pairing method which pairs electronic devices. Each electronic device includes a communication unit to communicate data and a light receiving unit to detect receiving light amount. The method includes the following. The electronic devices are set to a pairing standby state. Light intensity on the light receiving units is changed under a same light receiving environment. Time series data of receiving light amount detected by the light receiving unit of a second electronic device is transmitted from the second electronic device to a first electronic device. The electronic devices are paired based on time series data of receiving light amount detected by the receiving light units.
