<P>PROBLEM TO BE SOLVED: To improve fuel efficiency of an internal combustion engine while suppressing the generation of noise, and to secure running performance satisfactorily in a hybrid vehicle having the internal combustion engine capable of outputting power to one of front and rear wheels, and an electric motor capable of outputting power to the other of the front and rear wheels. <P>SOLUTION: In a case where an operating point of an engine 22, which corresponds to engine request power Pe* on an optimal fuel efficiency operation line, is included in a noise generation area, a target operating point of the engine 22 is set to an operating point (Ne1, Te1) on the optimal fuel efficiency operation line on a lower load side (lower power side) rather than the noise generation area except for a case when output of a motor MG3 should be restricted (Step S270), and a torque command Tm3* of the motor MG3 is set to output the shortfall of a power (value P1) output from the engine 22 to engine requirement power Pe* (step S230). <P>COPYRIGHT: (C)2013,JPO&INPIT |
