考虑油门开度快速变化的自动变速器换挡控制策略（AMT Shift Control Strategy Based on the Fleetness Changing of the Gas Pedal Aperture）
自动变速器 油门开度变化率 换挡
2009/9/25
在机械自动变速器三参数(油门开度、车速、加速度信号)换挡控制中，汽车惯性大会引起汽车车速响应速度相对于油门开度变化的滞后，在油门开度变化率比较大的情况下易出现频繁换挡现象。本文将油门开度变化率作为输入参数，提出了换挡四参数模糊控制方法。同时针对四参数模糊控制输入参数多、模糊规则多的问题，提出了双模糊四参数控制器方法，减少了模糊规则的数量，提高了处理器的运行能力。仿真结果验证了控制策略的正确性。
