电控机械式自动变速器(AMT)的换挡过程是动力传动系统联合控制的过程。换挡过程通常分为切断动力、挂挡和恢复动力三个阶段,其中在恢复动力阶段离合器与发动机的协调控制是关键,由于该过程的复杂性和不确定性,使得传统控制方法的使用效果欠佳。为此,本文基于现代智能控制理论,设计了一个三级递阶智能控制器使该阶段离合器与发动机控制智能化,从而提高换挡品质,并在桑塔纳2000AMT样车上进行了试验验证。
The shift process of electronically controlled mechanical automatic transmission (AMT) is the joint control of powertrain system. The shift process is usually divided into three phases: power cut-off, gear-in and power recovery. The coordinated control of the clutch and the engine during the restoration of the power is the key. Due to the complexity and uncertainty of the process, the effect of the traditional control method Poor. Therefore, based on modern intelligent control theory, a three-level hierarchical intelligent controller is designed to intelligently control the clutch and engine at this stage, so as to improve the gear shifting quality. The experiment is validated on the Santana 2000AMT prototype.
