<P>PROBLEM TO BE SOLVED: To prevent the occurrence of boxy sound resulting from the operation of an internal combustion engine and to improve the energy efficiency. <P>SOLUTION: In a hybrid vehicle which runs by converting power from the engine to torque by means of a planetary gear and two motors MG1, MG2 so as to output the power to a drive shaft, an action line of the engine 22 for avoiding the occurrence of the boxy sound is set based on an amount of generated electricity Pchg of the motor MG1 (S140), and the engine and the motors MG1, MG2 are controlled based on the set action line (S150 to S200). It is thus possible to prevent the occurrence of the boxy sound resulting from the operation of the engine and to operate the engine efficiently as much as possible. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
