<P>PROBLEM TO BE SOLVED: To prevent a voltage from increasing abnormally by allowing a motor torque command value to sharply decreases accompanying the speed increase, while a motor torque command value is limited to an outputable upper limit torque. <P>SOLUTION: While a motor torque command value is limited to the outputable upper torque of each speed, when it is decided that a speed VSP is ranging from speed regions VSP1 to VSP 2 where a motor torque command value sharply decreases, and the abnormal increase of a voltage is generated, when it is sharply increased, in step S21; and when it is decided that vehicle acceleration α is an abnormal voltage generation acceleration decision value αs or larger at an S22, a command to decrease an engine Te so that the vehicle acceleration α can be set so as to be the abnormal voltage generation acceleration decision value αs or smaller is issued in step S23. Thus, the decreasing speed of a motor torque command value tTm can be prevented from becoming sharp, according as the abnormal increase of voltage is generated by controlling the decrease in the engine torque. <P>COPYRIGHT: (C)2007,JPO&INPIT |
