Method and apparatus for controlling driving force of vehicle

A driving force controlling apparatus for a vehicle, comprising:

• driver's demanding torque setting means for setting a torque that a vehicular driver is demanding;
• slip condition detecting means for detecting a slip condition of vehicular road wheels;
• target engine torque setting means for setting a target engine torque in accordance with the slip condition;
• driving force control execution determining means for determining whether the driving force control should be executed in accordance with the slip condition;
• and
• engine output torque determining means for giving a determination of an output torque developed by an engine of the vehicle on the basis of the driver's demanding torque and the target engine torque, the target engine torque setting means outputting a value of the target engine torque to which the driver's demanding torque is assigned when no driving force control is determined to be executed.
