In this vehicle driving force control method, an estimated friction circle is calculated on the basis of a front-rear acceleration and a lateral acceleration, driving force is limited in accordance with the size of the estimated friction circle, and the rate of change in the size of the estimated friction circle while the vehicle is traveling is limited on the basis of a tire-generated force. Furthermore, in the driving force control method, the greater the tire generation force is, the greater the rate of change in the size of the estimated friction circle after limitation is.

    在本发明的车辆的驱动力控制方法中,基于前后加速度和横向加速度计算推定摩擦圆,根据推定摩擦圆的大小限制驱动力,并基于轮胎产生力限制车辆行驶中的推定摩擦圆的大小的变化速度。进而,在该驱动力控制方法中,轮胎产生力越大,限制后的推定摩擦圆的大小的变化速度越大。
