摘　　要：机械式自动变速器是对使用手动齿轮变速箱和干式摩擦离合器的传统动力传动系统进行改造,实现操作自动化而形成的一种机电一体化装置。汽车起步过程的离合器控制按照快 -慢 -快 3个阶段进行。离合器滑磨阶段的控制是解决问题的关键。从实际应用角度出发,深入分析了汽车起步过程中离合器接合控制的主要影响因素。以降低起步冲击度和减少离合器滑磨功为原则,提出了一种离合器控制策略。在装用AMT的桑塔纳轿车上进行的坡道起步道路试验结果表明,所提出的离合器控制策略得到了成功应用。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.
