<P>PROBLEM TO BE SOLVED: To more properly manage a charge storage ratio that is a ratio of a power amount that is dischargeable from an electric storage device, such as, a secondary battery in a hybrid vehicle having an engine and two motors, and to further improve the energy efficiency of the vehicle. <P>SOLUTION: Request power Ped which is requested of the engine is set, based on request torque Tr* requested of a driving axle (S110); target power Pe* is set by multiplying the request power Ped by a correction coefficient kp, based on atmospheric pressure Pa, when the charge storage ratio SOC of the electric storage device is less than a lower limit threshold SL (S140, S160); the target power Pe* is set by multiplying the request power Ped by a correction coefficient kp set to a value of 1.0, regardless of the atmospheric pressure Pa, when the charge storage ratio SOC is the lower limit threshold value SL or above (S150, S160); and the engine and the two motors are controlled (S170-S220), such that the set target power Pe* is outputted from the engine, the request torque Tr* is outputted to the driving axle, and traveling is performed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
