    摘要： There is provided an oil pressure control device for a belt-type continuously variable transmission which includes two pulleys and a belt provided between the two pulleys and wound around the two pulleys to transmit motive power, wherein each of the two pulleys has a movable sheave which moves by oil pressure supplied to a hydraulic chamber, wherein the oil pressure control device calculates a request torque according to a running state, wherein when calculating the oil pressure which is supplied to the hydraulic chamber of the movable sheave on the basis of the request torque, the oil pressure control device reduces the request torque if the request torque is greater by a predetermined value or more than an actual input torque which is inputted to the belt-type continuously variable transmission. Accordingly, it is possible to provide an oil pressure control device for a belt-type continuously variable transmission with which undesirable vibration can be avoided by means of stable speed-ratio control.

    摘要： First temporary capacity reduction control that when acceleration ON is judged during coasting lock-up, brings lock-up clutch (20) into slip state by decreasing torque transmission capacity of lock-up clutch and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is executed. Control unit performing second temporary capacity reduction control that when return of accelerator pedal depression is judged during the progress of returning to lock-up state, decreases torque transmission capacity again and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is provided. In second temporary capacity reduction control, torque transmission capacity is decreased with predetermined torque transmission capacity by which lock-up clutch is not fully disengaged being lower limit value. Abrupt engagement of lock-up clutch and engine racing can be therefore avoided when acceleration is changed from ON to OFF during control of lock-up clutch from disengagement or slip state to lock-up state.

    摘要翻译： 在滑行锁定期间判断为加速ON时的第一临时容量降低控制，通过减小锁止离合器的转矩传递能力使锁止离合器（20）进入滑动状态，并随后将锁止离合器返回到锁定状态 通过增加扭矩传递能力来执行。 控制单元执行第二临时容量降低控制，当在返回到锁定状态的过程中判断出加速踏板下压的返回时，再次降低转矩传递能力，随后通过增加转矩传递能力将锁止离合器返回到锁定状态 被提供。 在第二临时容量降低控制中，转矩传递能力随着锁定离合器未完全脱离的预定转矩传递能力而下降，为下限值。 因此，在锁止离合器从脱离或滑动状态到锁定状态的控制期间，当加速度从ON变为OFF时，可以避免锁止离合器和发动机运转的突然接合。

    摘要： When a torque converter (2) is being returned to a full engagement state as a result of an ON operation of an accelerator after temporary disengagement of the full engagement state, during the execution of control that achieves the full engagement state after increasing the rotation of an internal combustion engine (1) by means of slip engagement while expanding the torque transmission capacity of a lockup clutch (20), if it is determined that there has been a gain in the output torque of the internal combustion engine (1) when, within a prescribed period of time after the beginning of the control, the detected input/output differential rotation speed of the lockup clutch (20) is at or below a second prescribed value (”N2) that is smaller than a first prescribed value (”N1) after having increased to or above the first prescribed value, a prescribed capacity is added to the expanding torque transmission capacity of the lockup clutch (20). It is possible to avoid judder vibration caused by the release of an accelerator pedal during a transition to a lockup state.
