Drive force control device and drive force control method for vehicle

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.
