PROBLEM TO BE SOLVED: To provide a drive force controlling method for a vehicle that can reduce variation in acceleration and deceleration response due to difference in gear ratio, and to provide a drive force controlling device.SOLUTION: When a target drive torque tTc of a vehicle is changed, a drive force controlling method for a vehicle regulates a change rate of target power source torque tTps so that post-regulating target power source torque tTps_lim reaches a value tTps in accordance with the target drive torque tTc in the same reaching time T irrespective of a gear step of AT3, in regulating a change rate of the target power source torque tTps in accordance with the target drive torque tTc.SELECTED DRAWING: Figure 3
【課題】 ギヤ比の違いによる加減速レスポンスのバラツキを低減できる車両の駆動力制御方法および駆動力制御装置を提供する。【解決手段】 車両の目標駆動トルクtTcが変化したとき、目標駆動トルクtTcに応じた目標動力源トルクtTpsの変化率を制限するにあたり、制限後目標動力源トルクtTps_limがAT3のギヤ段に依らず同じ到達時間Tで目標駆動トルクtTcに応じた値tTpsに到達するように目標動力源トルクtTpsの変化率を制限する。【選択図】 図3
