<P>PROBLEM TO BE SOLVED: To improve the protection of an energy accumulation means in switching the control mode of a motor. <P>SOLUTION: In a hybrid automobile 20, when an accelerator is turned off during travel and a control mode other than an over-modulation control mode is set, a torque command for a motor MG2 is set at a torque decrease rate of first change degree, if the voltage of a battery 50 is not within a predetermined lower limit range. Meanwhile, if the voltage of the battery 50 lies within the lower limit range, a torque command Tm2* of the motor MG2 is set, at a torque decrease rate of second change degree which is more gentle than the first change degree, and driving of the motor MG2 is controlled so that the set torque command Tm2* is outputted. Thus, in an over-modulation control mode having low flowability, a torque command changing degree of the motor MG2 is made gentler, to suppress a divergence between a current command, based on the torque command Tm2* of the motor MG2 and an actual current extracted from the battery 50. <P>COPYRIGHT: (C)2010,JPO&INPIT |
