<P>PROBLEM TO BE SOLVED: To enable a motor to output torque necessary for turning off a clutch even when the rotation speed of a generator is low. <P>SOLUTION: A driving force control device for a vehicle includes: a first control part 60 for calculating a DC voltage command value with respect to an actual DC voltage value of a generator based on a motor torque command value, and for controlling the motor 4 based on the calculated DC voltage command value; a second control part 80 for calculating a d-axial and q-axial current command values to be supplied to the motor 4 based on the motor torque command value, and for controlling the motor 4 based on the calculated d-axial and q-axial current command values; and a control switching part 51 for, when motor torque is larger than a first threshold value, controlling the motor 4 by the first control part 60, and for, when the motor torque is less than the first threshold, controlling the motor 4 by the second control part 80. <P>COPYRIGHT: (C)2010,JPO&INPIT |
