Hybrid drive device

A hybrid drive device, comprising:

• an electric motor;
• an automatic transmission that outputs rotation of an input portion to an output portion with a speed of the rotation changed;
• a lubricating oil passage to which a lubricating oil pressure is supplied;
• and
• a first switching valve that is switched between a first state, in which the lubricating oil passage communicates with a first lubricating oil passage that guides lubricating oil in the lubricating oil passage to the automatic transmission, and a second state, in which the lubricating oil passage communicates with a second lubricating oil passage that guides the lubricating oil in the lubricating oil passage to the electric motor, wherein
• the electric motor and an internal combustion engine output shaft are operable in conjunction with the input portion,
• the first switching valve is switched from the first state in which the lubricating oil passage communicates with the first lubricating oil passage to the second state in which the lubricating oil passage communicates with the second lubricating oil passage, in the case where a vehicle is running at a speed of a predetermined value or less including a stationary state of the vehicle,
• the automatic transmission performs shifting by changing a power transfer path using a plurality of friction elements including a predetermined friction element that is engaged to establish a first speed and that is used for slip control,
• a branched lubricating oil passage is branched from the second lubricating oil passage and leads to the predetermined friction element, and a second switching valve is provided in the branched lubricating oil passage to be switched between a blocked state and a communicated state, and
• the second switching valve includes a control oil chamber communicating with a hydraulic servo for the predetermined friction element, and in the case where a predetermined pressure is supplied to the hydraulic servo, the second switching valve is switched from the blocked state to the communicated state so that the lubricating oil from the second lubricating oil passage is directly supplied to the predetermined friction element via the branched lubricating oil passage.
