Transmissions require a good shift feeling and improved fuel efficiency. In state-of-the-art stepped automated transmissions, the number of gear stages increases, and the lock-up area is expanded to improve fuel efficiency. However, this makes it difficult to obtain a good shift feeling and it takes a large number of calibration man-hours. Therefore, to reduce the number of calibration man-hours and improve the shift feeling, we propose a slip control law between the engine and the clutch, which is composed of a proportional-integral-derivative (PID) controller and a disturbance observer. Moreover, PID gain is adjusted online by installing an automatic tuning method, which does not require a controlled object model. The effects of the proposed method are verified via an experiment using an actual vehicle. The experimental results show that the proposed method is effective for automatically adjusting PID gain and improving the shift feeling of the stepped automated transmission.

使用无模型自整定比例积分微分控制的离合器到离合器换档惯性阶段的滑差控制

变速器需要良好的换档感觉和提高燃油效率。在最先进的阶梯式自动变速器中，齿轮级数增加，锁定区域扩大，以提高燃油效率。然而，这使得难以获得良好的换档感觉并且需要大量的校准工时。因此，为了减少校准工时并改善换档感觉，我们提出了发动机和离合器之间的滑移控制律，它由比例积分微分 (PID) 控制器和干扰观测器组成。此外，PID增益是通过安装自动调谐方法在线调整的，不需要受控对象模型。通过使用实际车辆的实验验证了所提出方法的效果。
