摘要： A power train for a machine is provided having a transmission including a plurality of gears configured to produce multiple output ratios when selectively engaged. The power train also has at least one sensor configured to sense at least one parameter indicative of a condition requiring a disablement of a gear output ratio during a downshifting event. In addition, the power train has a controller configured to regulate the transmission in either a first or a second mode in response to the at least one parameter. At least one of the gear output ratios is disabled during downshifting events occurring while the controller regulates the transmission in the first mode. Furthermore, all gear output ratios are available during downshifting events occurring while the controller regulates the transmission in the second mode.

摘要： A hydraulic control apparatus of an automatic transmission estimates the possibility of there being a demand for a shift into a gear lower than the current gear during a power-off downshift operation. If there is a possibility that there will be a demand for a shift into the next gear during the shift, the hydraulic control apparatus starts an operation for supplying an apply preparation hydraulic pressure in preparation for the shift into that next gear.

摘要： PROBLEM TO BE SOLVED: To provide a shift controller for an automatic transmission capable of performing prompt shift and avoiding torque fluctuation at an intermediate gear stage, by engaging a first shift engagement element after releasing first and second shift release elements and by forming a low speed stage by engaging a second shift engagement element while performing feedback control of torque capacity of the second shift release element, during a downshift. SOLUTION: A shift control means performs control to form three forward speed stages by engaging a clutch C-3 while preforming feedback control of torque capacity of a clutch C-2, after releasing a brake B-1 and the clutch C-2 and then engaging a clutch C-1. As a result of releasing the brake B-1 and the clutch C-2 prior to engagement of the clutch C-1, time for shifting can be shortened, and torque fluctuation can be reduced to avoid occurrence of an uncomfortable shift shock.

摘要翻译：要解决的问题：提供一种能够进行快速换档的自动变速器的换档控制器，并且在中间档位时避免扭矩波动，通过在释放第一和第二换档释放元件之后接合第一换档接合元件并且通过形成在降挡期间，通过接合第二换档接合元件同时执行第二换挡释放元件的扭矩容量的反馈控制，来实现低速级。解决方案：在释放制动器B-1和离合器C-3之后，通过接合离合器C-3同时预先执行离合器C-2的扭矩能力的反馈控制，变速控制装置进行三个前进档的控制，然后接合离合器C-1。在离合器C-1接合之前释放制动器B-1和离合器C-2的结果可以缩短变速时间，并且可以减小转矩波动，以避免发生不舒服的换档冲击。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce unevenness of torque in shifting a clutch of an automatic MT (manual transmission). SOLUTION: In a torque assist type automatic MT, an assist clutch is controlled to reduce an increased speed of transmitted torque by engagement with time, in releasing an engaged clutch while engaging the assist clutch. In a twin-clutch type automatic MT, one of twin clutches is controlled to reduce the increased speed of the transmitted torque by engagement with time in releasing the engaged clutch before original gear shift, while engaging the clutch corresponding to an input shaft having a role to compensate torque interruption.

摘要： PROBLEM TO BE SOLVED: To perform multiple gear shifts with good response while preventing gear shift shock from occurring by the multiple gear shifts. SOLUTION: A method for shifting to a third shift stage according to the engagement pattern of each frictional engagement element in the steady state of the third shift stage is changed when a request for shifting to the third shift stage occurs during a shifting from a first shift stage to a second shift stage. For example, if a frictional engagement element for continuing the engagement or release of the engagement of the engagement pattern of the third shift stage with the engagement pattern of the second shift stage is present (or if a request for shifting to a third shift stage during 5 to 4 shift operation or a request for shifting to a second shift stage during 4 to 3 shift operation), the engagement or released of the engagement of the frictional engagement element is controllably continued, and a shift stage is transferred from the second shift stage to the third shift stage by starting the engagement or disengagement control for the other frictional engagement element with varying engagement or release state so as to cope with the engagement pattern of the third shift stage.

摘要： PCT No. PCT/EP95/01794 Sec. 371 Date Nov. 15, 1996 Sec. 102(e) Date Nov. 15, 1996 PCT Filed May 12, 1995 PCT Pub. No. WO95/32375 PCT Pub. Date Nov. 30, 1995The proposal is for a process for controlling an automatic transmission in which, on the basis of a speed-change demand, an electronic control device determines a mode of changing (F1, F2, F3), compares an existing operation point with a theoretical operation point in which the theoretical operation point depends upon the mode of changing and selects a first or second change range.
