Abstract

See full text

An oil supply device has: a first hydraulic pump driven by power transmitted through a power transmission path; a second hydraulic pump driven by a second driving force source independent from the power transmission path; and a hydraulic circuit. In a specific state in which a first forward speed is formed by oil discharged from the second hydraulic pump being supplied to a hydraulic drive portion, when a failure occurs in which a discharge pressure of the second hydraulic pump is decreased, a state of the hydraulic circuit is switched from a first state in which oil discharged from the second hydraulic pump is supplied to the hydraulic drive portion to a second state in which oil discharged from the first hydraulic pump is supplied to the hydraulic drive portion.
