Embodiment Construction

[0027] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, like parts are denoted by like reference numerals. Similar parts have similar names and similar functions. Therefore, redundant description will be omitted.

[0028] A hybrid vehicle equipped with a control device according to a first embodiment of the present invention will be described in detail with reference to FIG. 1 . In the described embodiment, the hybrid vehicle is a FR (Front Engine Rear Drive) vehicle, but it may be a vehicle other than the FR vehicle. Although a hybrid vehicle is described in this embodiment, a vehicle having only one engine as a drive source may also be implemented.

[0029] The hybrid vehicle includes a hybrid system 100 as a drive source, an automatic transmission 400 , a propeller shaft 500 , a differential gear 600 , rear wheels 700 , and an ECU (Electronic Control Module) ...

Abstract

In a control apparatus for a powertrain that includes an automatic transmission, occurrence of slip in a one-way clutch (450) is determined when one gear is formed if a first rotation member and a second rotation member of the one-way clutch (450) rotate relatively. If slip in the one-way clutch is detected, it is determined whether [the rotational speed difference between the first rotation member (452) and the second rotation member (454) has increased. If the rotational speed difference between the first rotation member (452) and the second rotation member (454) has increased when slip is detected in the one-way clutch (450), a control is executed to engage a predetermined frictional engagement element (B1).

Description

technical field [0001] The present invention relates to a control device and a control method for a power train, and a program for implementing the control method. In particular, the present invention relates to a technique for controlling a power train including an automatic transmission in which one gear is formed by engaging a one-way clutch, and another gear other than the one is formed by engaging a predetermined frictional engagement element. a file. Background technique [0002] In a conventional automatic transmission, gears are automatically formed depending on vehicle speed. An automatic transmission has a plurality of frictional engagement elements, and gears are formed in accordance with combinations of the frictional engagement elements to be engaged. [0003] In such automatic transmissions, gears are appropriately shifted by selectively engaging and releasing frictional engagement elements. When a shifting operation is performed, if the timing of engaging a...
