摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of a large shock due to engagement of a C4 clutch. SOLUTION: In a state that an elapsed time after permission of fail safe for engaging the C4 clutch by turning off a SL solenoid at neutral failure when a reverse gear stage is not formed is shorter than a threshold value T(0) (YES in S130), an ECU executes a program including a step (S140) for stopping the fail safe when satisfying conditions that an accelerator opening is larger than a threshold value PA(0) and a value obtained by subtraction of synchronous rotation speed from turbine rotation speed is larger than a threshold value ΔN(2) (YES in S134). When satisfying conditions that a throttle opening is smaller than a threshold value THA(0) and engine rotation speed NE is lower than a threshold value NE(0), the fail safe is permitted to start.

摘要： PROBLEM TO BE SOLVED: To provide a method and system for quickly and effectively adjusting an automatic transmission when replacing/repairing components. SOLUTION: First property information showing individual property errors of a friction engaging element 51 of the automatic transmission and a plurality of components 41, 43, 71-78 as parts of its hydraulic control device 40, and a correction value k for correcting a control signal Id supplied to the hydraulic control device 40 depending on the property errors of the plurality of components are stored in a memory 32 in a re-writable manner. When a predetermined component 41 as part of the hydraulic control device 40 is replaced with a replacing component manufactured in an allowable error, the property value for the component stored in the memory 32 is re-written into second property information showing a zero property error, a new correction value k is calculated in accordance with the second property information and the property information stored in the memory 32 for non-replacing components 43, 71-78, and the correction value k in the memory 32 is updated.

摘要：【課題】アイドリングストップ制御の実行時に、特定の摩擦係合要素に直接的に油圧を供給可能とするものに対し、特別な弁機構を新たに付加することなく、他の油圧経路に作動油が流れてしまうことを阻止可能とする自動車の油圧供給制御装置を提供する。
【解決手段】自動変速機の油圧制御回路４に、機械式オイルポンプＭＯＰと電動オイルポンプＥＯＰとを備えさせる。電動オイルポンプＥＯＰの吐出側を短絡油圧供給路４３０を介して第１クラッチＣ１の油圧サーボの直上流側に連通させる。アイドリングストップ時、第１クラッチＣ１上流側のリニアソレノイド４１１を強制閉鎖状態にし、電動オイルポンプＥＯＰからのオイルがマニュアルシフトバルブ４１０側へ流れ出るのを阻止する。

摘要： Since there are provided an inertia phase final period decision unit which decides whether or not the final period of the inertia phase of a speed change is currently occurring, a return control unit which, taking an affirmative result of this decision as a starting condition, performs return control in order to return from the torque down control by gradually decreasing the amount of decrease of output torque, a speed change progression decision unit which, during this return control from the torque down control, decides whether or not the speed change is progressing, and a resumption control unit which resumes the torque down control if the result of this decision is negative, accordingly, during the return control from the torque down control, by resuming the torque down control when there is no progression with the speed change.

摘要： A control apparatus includes: a gear-shift prediction unit (31) that predicts whether a power-on downshift using a clutch-to-clutch shift operation needs to be performed as a next gear-shift; and a standby pressure supply control unit (32) that supplies a pressure for placing a first friction engaging element, which contributes to the next gear-shift, in the standby state, which is achieved immediately before engagement of the first friction engaging element is started, to the first friction engaging element, when the gear shift prediction unit (31) predicts that the power-on downshift using the clutch-to-clutch shift operation needs to be performed as the next gear-shift. When it is determined that a condition for performing the next gear-shift is satisfied based on the accelerator operation and the vehicle drive state, a shift command signal (Ia to Ie) is output to bring the first friction engaging element out of the standby state and engage the first friction engaging element

摘要： A duty ratio for controlling an engagement force of a friction engagement device on the side of upshift engagement is corrected by an amount corresponding to an intermediate correction control value in the course of the shift. In addition, on a prerequisite condition that learning correction of a constant standby pressure control value at the start of the shift is converged, learning correction is performed for the intermediate correction control value according to a gradient of a turbine speed. Thus, a shift shock is prevented from occurring due to abrupt engagement of the friction engagement device and the like at the completion of the shift.
