Abstract

A program is executed which includes a step (S1OO) of calculating a base required driving force, a step (S200) of calculating a reference driving force, a step (S400) of calculating a final required driving force on which a vibration suppression filtering process has been performed when the base required driving force is greater than a reference driving force, and a step (S500) of calculating a final required driving force on which the vibration suppression filtering process has not been performed when the base required driving force is equal to or less than the reference driving force.

Description

technical field [0001] The present invention relates to a vehicle driving force control apparatus and a vehicle driving force control method of a vehicle having a power train formed of a drive source and a transmission. More particularly, the present invention relates to an apparatus and method for controlling driving force of a vehicle to suppress torsional vibration in a power train. Background technique [0002] In vehicles, the power train tends to produce unpleasant vibrations during acceleration with increased engine load. These unpleasant vibrations are mainly caused by torsional vibrations of the drive shaft in the power train and are generated when the engine torque, which has increased with increasing engine load, includes a resonant frequency component of the power train . This torsional vibration becomes more prominent when the demand driving force (i.e., the target driving force) is greater. [0003] Japanese Patent Application Publication No. JP-A-2003-41987...
