The invention provides an accelerator pedal pre-control method, system and device under the plain working condition and a medium. The method comprises the steps that the expected vehicle speed of a vehicle is predicted according to the current vehicle speed; judging whether the vehicle enters a plain working condition; if the vehicle enters the plain working condition, the engine demand torque is calculated according to the expected vehicle speed by using a kinetic model; the expected opening degree of an accelerator pedal is determined according to the engine demand torque and the rotating speed; when the actual accelerator opening degree of the vehicle belongs to large-amplitude accelerator stepping, the expected opening degree is adjusted to be the actual accelerator opening degree of the vehicle; when the expected opening degree belongs to a small accelerator, the expected opening degree is adjusted to be 0; when the actual accelerator opening degree of the vehicle ranges from 10 to 90, scaling adjustment is conducted on the expected opening degree, and the strategy accelerator opening degree is generated; and output control over the opening degree of the strategy accelerator is conducted. According to the method, the robustness of the whole vehicle accelerator control strategy can be improved, the adaptability of the whole vehicle to different drivers is improved, and the overall fuel consumption reduction target is achieved.

    本发明提出的一种平原工况下的油门踏板预控制方法、系统、装置及介质,所述方法包括:根据当前车速预测车辆的期望车速;判断车辆是否进入平原工况;如果车辆已进入平原工况,利用动力学模型根据期望车速计算出发动机需求扭矩;根据发动机需求扭矩和转速确定油门踏板的期望开合度;当车辆的实际油门开合度属于大幅度踩踏油门时,将期望开合度调整为车辆的实际油门开合度;当期望开合度属于小油门时,将期望开合度调整为0;当车辆的实际油门开合度在10‑90之间时,对期望开合度进行缩放调整,生成策略油门开合度;进行策略油门开合度的输出控制。本发明能够提高整车油门控制策略鲁棒性,改善整车对不同驾驶员的适应性,实现整体的降油耗目标。
