<p><P>PROBLEM TO BE SOLVED: To suppress noise of collision in an engagement portion of a concave and convex portions of a transmission device which is transmitted from a drive force source to tires. <P>SOLUTION: The drive force control device obtains an alternately changing vibration torque while using a request torque transmitted from the drive force source to the tires as a reference, transmits the vibration torque from the drive force source to the tires and controls a friction coefficient between the tires and a road surface, wherein a power transmission device for transmitting torque by a mating force between the determining and convex portions is provided on the torque transmission passage. The drive force control device is provided with: a determining means for determining whether the request torque is in a drive region or a regenerative region, and whether or not the vibration torque moves forward and backward between the drive region and the regenerative region (step S4); and a correcting means for correcting the vibration torque so that the vibration torque can be generated in the same region as that of the request torque when the determining means has determined that the request torque is in either the drive region or the regenerative region and the drive torque moves forward and backward between the drive region and the regenerative region (steps S5, S6). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
