機械式自動變速器是對使用手動齒輪變速箱和乾式摩擦離合器的傳統動力傳動系統進行改造，實現操作自動化而形成的一種機電一體化裝置。汽車起步過程的離合器控制按照快－慢－快3個階段進行。離合器滑磨階段的控制是解決問題的關鍵。從實際應用角度出發，深入分析了汽車起步過程中離合器接合控制的主要影響因素。以降低起步衝擊度和減少離合器滑磨功為原則，提出了一種離合器控制策略。在裝用AMT的桑塔納轎車上進行的坡道起步道路試驗結果表明，所提出的離合器控制策略得到了成功應用。

The conventional driveline with manual gearbox and dry clutch can be retro-fitted to manipulate automatically, so that the electo-mechanical components or the Automated Mechanical Transmission has been obtained. The clutch engagement position for automotive start-up process can be controlled by the fast-low-fast speed. How to control the clutch engagement during the slipping stage is the key to clutch control. The mostly influent factors of the clutch engagement during start-up process have been analysed thoroughly from the practical point of view. The strategy of clutch control has been proposed on the principle of lessening the start-up jerk and the friction work. It is successfully applied to Santana model, which can be proved by the road test of the vehicle on the slope.
