Abstract

A hybrid vehicle including an engine, a drive motor, a first oil pump, and a second oil pump is configured to, during forward travel, supply components to be cooled or lubricated with oil discharged from a discharge port of the first oil pump and a discharge port of the second oil pump via an oil passage, while the hybrid vehicle is configured to, during reverse travel, compensate for a driving force by supplying oil discharged from the discharge port of the second oil pump to the discharge port of the first oil pump via the oil passage to cause the first oil pump to operate as a hydraulic motor.
