Embodiment Construction

[0016] Below, refer to Figure 1 to Figure 7 , to describe the embodiment of the present invention. The drive device according to the embodiment of the present invention is applied to a hybrid vehicle including an engine and a motor generator as driving sources for travel. figure 1 It is a diagram schematically showing the overall structure of the drive device 100 for the hybrid vehicle according to the present embodiment.

[0017] Such as figure 1 As shown, a driving device 100 for a hybrid vehicle includes an engine (ENG) 1 , a motor generator (MG) 2 , and an automatic transmission 3 .

[0018] The engine 1 is an internal combustion engine (for example, a gasoline engine) that mixes intake air supplied through a throttle valve and fuel injected from an injector in an appropriate ratio, ignites them with a spark plug, and burns them to generate rotational power. In addition, various engines, such as a diesel engine, can also be used instead of a gasoline engine. A control...

Abstract

A drive device (100) for a hybrid vehicle is provided with a planetary gear mechanism (10) connected to an internal combustion engine (1), an input shaft (3a) of a transmission (3), and a planetary gear mechanism (10) of a motor generator (2). The transmission (3) has an engagement mechanism (TWC) capable of switching between a one-way rotation permitted state in which only one-way rotation of a rotating shaft (33) connected to an input shaft (3a) of the transmission (3) is permitted, and a rotation prohibited state in which two-way rotation is restricted. When a shift command unit (41) instructs that switching of a range in which the engagement mechanism (TWC) needs to be switched from a one-way rotation-permitted state to a rotation-prohibited state is necessary, the shift command unit (41) transmits a shift command to the engagement mechanism (TWC). The control unit (4) controls the motor generator (2) such that the rotational speed of the input shaft (3a) becomes zero, then controls the engagement mechanism (TWC) such that the engagement mechanism is switched from a one-way rotation-permitted state to a rotation-prohibited state, and controls actuators (C1, C2, B1, B2) for driving the transmission such that the indicated gear is established.

Description

technical field [0001] The present invention relates to a driving device for a hybrid vehicle provided with a transmission including an engagement mechanism such as a two-way clutch. Background technique [0002] Conventionally, it is known to provide an automatic transmission of a vehicle with a two-way clutch capable of switching between a one-way rotation permitting state allowing only one-way rotation and a rotation preventing state restricting two-way rotation. This device is described in Patent Document 1, for example. In the device described in Patent Document 1, when the gear position is switched from forward gear to reverse gear, in order to prevent damage to the two-way clutch, the input shaft is activated by the engagement action of a plurality of hydraulic engagement mechanisms operated by hydraulic pressure. After the rotation speed of the engine reaches 0, the two-way clutch is switched to the rotation prevention state, and then the reverse gear is engaged. ...
