摘要： PROBLEM TO BE SOLVED: To acquire a touch point of a clutch without affecting the acceleration/deceleration state of a vehicle during traveling of the vehicle in a power transmission control device for the vehicle using a double clutch transmission.SOLUTION: During vehicle traveling, an unselected system (system where the clutch is disengaged) within the transmission is made in an open state (t1). Then, a clutch stroke St2 of the clutch in the unselected system is gradually increased from zero (after t2). Thus, rotational frequency Ni2 of an input shaft in the unselected system is increased. After a time point (t3) where the increased Ni2 reaches engine speed Ne, the St2 is gradually decreased. This decreases the Ni2. The St2 at a time point (t4) where a change rate of the Ni2 becomes zero is acquired as the touch point of the clutch in the unselected system.
摘要翻译：要解决的问题：在使用双离合器变速器的车辆动力传递控制装置中车辆行驶期间，不影响车辆的加速/减速状态来获取离合器的接触点。解决方案：在车辆行驶期间，变速箱内的未选择系统（离合器分离的系统）处于打开状态（t1）。然后，未选择系统中的离合器的离合器行程St2从零（t2之后）逐渐增加。因此，未选择的系统中的输入轴的转速Ni2增加。在增加的Ni2达到发动机转速Ne的时间点（t3）之后，St2逐渐减小。这会减少Ni2。获取Ni2变化率为零的时间点（t4）的St2作为未选择系统中的离合器的接触点。

摘要： PROBLEM TO BE SOLVED: To provide a control device for an automatic transmission capable of executing a proper pre-shift control in accordance with the condition of a vehicle running. SOLUTION: In case a vehicle is running with one of its clutches put in engagement, an ECU determines whether it is a heavy loaded/towing condition in which the vehicle is running with a heavy load or towing (Steps S14 and S17). If the heavy loaded/towing condition is determined (Yes in both Steps S14 and 17), the ECU moves the down-side pre-shift line to the high-speed side so that shift control to the down-shift side is executed in the condition that the vehicle body speed is higher than that in the case no heavy loaded/towing condition is presumed (Step S26).

摘要： PROBLEM TO BE SOLVED: To enable slip control with rapid response and assuring stability even in a high engine speed, high engine torque state. SOLUTION: An oil pressure command value for carrying out slip-control of a lock-up clutch of a torque converter 4 is calculated from a feedforward oil pressure value calculated by an FF value calculating mean 21 and a feedback oil pressure value calculated by a feedback value calculating means 22. When calculating the feedback oil pressure value, a deviation out-of-range determining means 14 determines whether or not a deviation between an actual rotational speed difference and a target rotational speed difference is outside of a predetermined range, and if the deviation is outside of the predetermined range, a correction value is calculated by a feedback value correcting means 23 to correct the feedback oil pressure value. Therefore, when the deviation is outside of the predetermined range, the actual rotational speed difference is brought into convergence with the target rotational speed difference with rapid response, and when the deviation falls within the predetermined range, normal feedback control is adopted to assure stability without overshooting.

摘要： PROBLEM TO BE SOLVED: To provide a transmission and a method of shift control for the transmission, capable of reducing the unpleasant feeling to a driver by enabling completion of a pre-shift to a suitable change-speed stage when the change-speed is requested. SOLUTION: The transmission 1 includes a change-speed stage anticipating means. A gear mechanism selection means requires a time in shifting a current change-speed stage, as a pre-shifting time for selecting the latter change-speed stage to another change-speed stage. The change-speed stage anticipating means operates the gear-mechanism selecting means while adopting a temporary change-speed stage as a subsequent change-speed stage when the temporary change-speed stage, which is estimated from a state of vehicle after the pre-shift time, the state of vehicle being relevant to each element of an anticipated change-speed stage group that is made up of one or more of a plurality of the change-speed stages that can be selected by the one of the gear-mechanism selecting means being set on one of the input shafts out of first and second input shafts, that is disconnected from a power source, coincides with an anticipated change-gear stage which corresponds to the pre-shift time.
