1. A drive force control device for a vehicle, the vehicle comprising a continuously variable transmission that varies an output rotation of a motive force source and transmits a rotation after variation to a drive wheel, the drive force control device comprising:
an accelerator pedal opening sensor that detects an accelerator opening of an accelerator pedal with which the vehicle is provided; and
a programmable controller programmed to:
calculate a target drive force on the basis of the accelerator opening,
calculate a target transmission input rotation speed on the basis of the target drive force,
calculate a target transmission input torque on the basis of the target drive force,
control a speed ratio of the continuously variable transmission to realize the target transmission input rotation speed,
control an output torque of the motive force source to realize the target transmission input torque,
calculate a target transmission input rotation speed basic value on the basis of the target drive force,
calculate the target transmission input rotation speed on the basis of the target transmission input rotation speed basic value and an individually required target transmission input rotation speed,
calculate a target drive force basic value on the basis of the accelerator opening,
calculate a target transmission input rotation speed lower limit basic value on the basis of an individual requirement, and
calculate the target drive force on the basis of the target drive force basic value and the target transmission input rotation speed lower limit basic value.
