The invention relates to the technical field of automatic driving, and provides an automatic driving accelerator opening degree control method based on a self-adaptive PID (Proportion Integration Differentiation) algorithm, which mainly comprises the following steps of: 1, acquiring accelerator pedal voltage value data, and calculating the actual accelerator pedal opening degree when a pedal acts according to the pedal voltage value data; 2, the actual accelerator pedal opening degree is substituted into a preset speed solving model, the expected accelerator pedal opening degree is obtained, and the vehicle speed is adjusted to the expected vehicle speed according to the expected accelerator pedal opening degree; the vehicle speed is adjusted in real time through the opening degree of the accelerator, the reaction time of the adjusting process is short, jolt is avoided in the adjusting process, and comfortable experience can be brought to a user.

    本发明涉及自动驾驶技术领域,提供了一种基于自适应PID算法的自动驾驶油门开度控制方法,其方法主要包括如下步骤:步骤1:采集油门踏板电压值数据,通过所述踏板电压值数据计算得出踏板动作时的实际油门踏板开度;步骤2:将实际油门踏板开度代入预设的速度求解模型中,得出期望油门踏板开度,根据期望油门踏板开度调节车速至期望车速;通过油门开度对车速进行实时调节,调节过程的反应时间短,且调节过程中不产生颠簸,能够给用户带来舒适的体验感。
