<p><P>PROBLEM TO BE SOLVED: To suppress noise of collision from being generated in a transmission path of a torque transmitted from a drive force source to tires when the torque is vibrated. <P>SOLUTION: The drive force control device obtains a request torque transmitted from the drive force source to the tires when a vehicle runs, obtains a vibration torque from the request torque, and transmits the vibration torque from the drive force source to the tires to control a friction coefficient. The drive force control device is provided with: a run determining means for determining whether or not the vehicle runs in cornering (step S1); a request torque setting means for setting the request torque when the vehicle runs in cornering to be higher than the request torque when the vehicle runs forward (step S3); a determining means for determining whether or not the request torque is in a drive region and whether or not the vibration torque alternately moves forward and backward between the drive region and the regenerative region (steps S6, S7, S8); and a correcting means for removing the part equivalent to the regenerative region from the vibration torque when the request torque is in the drive region and the vibration torque alternately moves forward and backward between the drive region and the regenerative region (step S9). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
