<P>PROBLEM TO BE SOLVED: To provide a vehicle driving force controller for properly implementing a control corresponding to a rollback speed in a rollback state during a backlash reducing control. <P>SOLUTION: An output from an engine 2 is transmitted to left and right front wheels 1L, 1R, and also transmitted to a power generator 7. A voltage generated by the power generator 7 is supplied to a motor 4. Left and right rear wheels 3L, 3R are driven by an output from the motor 4. When a vehicle is in the rollback state during a four-wheel drive waiting state (the backlash reducing control) prior to a change to a four-wheel driving state, a magnetic field current instruction value of the motor is reduced to a normal magnetic field current instruction value during the backlash reducing control or less in response to a rollback speed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
