The invention discloses an accelerator pedal self-adaptive control method and system based on vehicle speed, and the method comprises the steps: obtaining driving comfort intervals of different accelerator opening degrees based on drivability and pedal feedback force feeling; dividing the vehicle speed into a low-speed section, a medium-speed section and a high-speed section according to the driving comfort section; an offset module for correcting the accelerator opening degree is used for randomly correcting the accelerator opening degree in any interval of low speed, medium speed and high speed; and according to different driving modes, the opening degree of the accelerator is finely adjusted again, and accelerator-torque control curves of low-speed, medium-speed and high-speed driving are obtained by combining the torque output two-dimensional tables of the different driving modes. Based on an existing vehicle control unit, no extra hardware cost needs to be added; the accelerator opening degree in any interval of low speed, medium speed and high speed can be corrected at will, and high flexibility is achieved; calibration is convenient, and only a vehicle road test certificate is needed; the original driving feeling is improved and the driving fatigue is reduced.

    本发明公开了一种基于车速的油门踏板自适应控制方法及系统,基于驾驶性及踏板回馈力感觉,获得不同油门开度的驾驶舒适区间;根据所述驾驶舒适区间把车速分为低速、中速、高速三个区间;利用一个油门开度修正的offset模块任意修正低速、中速、高速任何区间的油门开度;根据不同驾驶模式,再次微调油门开度,结合不同驾驶模式的扭矩输出二维表获得低速、中速、高速行驶的油门‑扭矩控制曲线。本发明基于现有整车控制单元,无需额外增加任何硬件成本;可任意修正低速、中速、高速任何区间的油门开度,具有高度灵活性;标定方便,仅车辆路试验证即可;改善原有驾驶感受,降低驾驶疲劳。
