<P>PROBLEM TO BE SOLVED: To provide a vehicle that travels by outputting torque necessary for traveling while suppressing LC resonance. <P>SOLUTION: The vehicle is configured in such a manner that when the rotational speed Nm2 of a motor MG2 is within a resonance region (a region from N1 to N2) where LC resonance occurs, a torque command Tm2* of the motor MG2 is corrected to be smaller by predetermined torque ΔT (S160); accompanied with the correction, torque command Tm1* of a motor MG1 is corrected to be smaller by the product of the predetermined torque ΔT and a gear ratio ρ, and target torque Te* of an engine 22 is corrected to be larger by the product of the predetermined torque ΔT and the sum of the gear ratio ρ and 1 (1+ρ) (S170, S180); and the engine 22, motors MG1, MG2, and a boost converter 55 are controlled by using the corrected target torque Te* and corrected torque commands Tm1*, Tm2*. Thereby, the vehicle can travel by outputting required torque Tr* to a drive shaft while suppressing the LC resonance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
