WIPO Patent Application WO/2019/208694
Kind Code:

Abstract:
An oil supply device (7) provided with: a first hydraulic pump (31) driven by power transmitted along a power transmission path; a second hydraulic pump (32) driven by a second drive power source (M2) independently of the power transmission path; and a hydraulic circuit (8). In a specific state in which a first forward stage is formed as oil discharged by the second hydraulic pump (32) is supplied to a hydraulic drive unit (70) of a specific engagement device, in the event of a failure such that the discharge pressure of the second hydraulic pump (32) is reduced, the state of the hydraulic circuit (8) is switched from a first supply state in which the oil discharged by the second hydraulic pump (32) is supplied to the hydraulic drive unit (70) to a second supply state in which the oil discharged by the first hydraulic pump (31) is supplied to the hydraulic drive unit (70).
