<P>PROBLEM TO BE SOLVED: To secure a lubricating flow rate of a second clutch while preventing performance deterioration of an electromotive oil pump at high oil temperature. <P>SOLUTION: A hybrid vehicle includes: a first clutch interposed between an engine and a motor generator; and a second clutch interposed between a motor generator and a driving wheel. The hybrid vehicle includes: a mechanical oil pump; an electromotive oil pump; a start time slip control means which controls the second clutch in the slip fastening condition when vehicle starting in a hybrid travel mode; a motor temperature estimation means (S5) which estimates a temperature of a magnet of an electric motor based on the temperature of hydraulic oil and the operation condition of the electric motor, when controlling the second clutch in the slip fastening condition (S2); and a motor limiting means (S8, S10) to limit and lower the output torque and the lower limit of the rotation speed when the estimated temperature of the magnet exceeds the limit temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
