Abstract:
1. A hybrid vehicle, comprising: an engine and an electric motor each configured to generate vehicle drive force; a power storage portion configured to be charged and discharged; a power converting portion that converts power received from said power storage portion for driving said electric motor; a first cooling mechanism that cools said electric motor via a first cooling medium, the first cooling medium being oil; and a second cooling mechanism that cools said power converting portion via a second cooling medium, the second cooling medium being water, said first cooling mechanism comprising: said second cooling mechanism comprising: said engine stopping intermittently in accordance with a traveling situation, said first and second feeding mechanisms being operable when said engine is stopped, and said control portion being configured to (1) control said path switching portion so that said second cooling medium circulates through a path which includes said power converting portion and said second heat exchanging portion at a first flow velocity, when the temperature of said second cooling medium is at or above a prescribed value, and (2) control said path switching portion and said second feeding mechanism so that said second cooling medium circulates through said bypass path at a second flow velocity that is greater than the first flow velocity, when the temperature of said second cooling medium is below the prescribed value.
