基于载荷和坡度的商用车AMT换挡规律修正方法

Performance of commercial vehicle AMT based on load and slope shift law correction method

针对导致商用车AMT换挡规律性能下降的动态载荷和坡度问题,通过对行驶负载和动态坡度的动态识别制定换挡规律修正方法,从而使得整车性能在动态路况下得到改善。实车实验显示修正后的换挡规律很好地解决了商用车AMT因不适应动态工况性能差和频繁换挡的问题,改善了驾驶性。

According to the dynamic load and slope problem of commercial vehicle AMT shift law performance decline, by a method of correcting shift schedule of dynamic identification of driving load and dynamic slope, make vehicle performance improved under dynamic road conditions. The real vehicle experiment shows that the modified shift law can solve the problem of poor performance and frequent shift of the corn mercial vehicle AMT driving in dynamic condition.
