Abstract

The invention relates to an engine starting gear used in a mixing motor vehicle power transmitting device. In the engine starting gear, the engine starting gear (94) changes a starting method of an engine (8) when an automatic speed changing part (20) executes speed changing relative to the starting method of the engine (8) when the automatic speed changing part (20) is not variable. Therefore, the starting operation of the engine (8) negatively affects the speed changing of the automatic speed changing part (20). During speed changing period of the automatic speed changing part (20), the starting operation of the engine (8) is started, compared with responsibility realized on an acceleration required by a driver in starting operation after the automatic speed changing part (20) has completed the speed changing, thereby furthermore increasing responsibility.

Description

technical field

[0001] The present invention relates to a control device for a hybrid vehicle power transmission device. More specifically, it relates to a hybrid vehicle power transmission device having an engine and an electric motor and a technique for starting the engine during switching from a motor drive mode to an engine drive mode, the engine consisting of an internal combustion engine as a drive power source to operate vehicle. Background technique

[0002] In the prior art, there is known a hybrid vehicle driving apparatus in which driving torque supplied from a main power source composed of an engine, a first electric motor and a differential mechanism is transferred to drive wheels via an output shaft, and the second The electric motor is connected to the output shaft via the automatic transmission. For this hybrid vehicle driving device, a control device is heretofore known in which a vehicle occupant is prevented from being subjected to an increased shock due...
