摘　　要：在电控机械式自动变速器AMT中主要包含原MT本体、电控单元、离合器执行机构、选换挡执行机构和传感器。在商用车领域,离合器气动执行机构被广泛应用,气动执行机构具有工作环境适应性好、动作迅速、反应快、负载大,可以适应高力矩输出的应用等优点,但气动执行器的主要缺点是响应较慢、控制精度欠佳,对控制技术提出了较高的要求。本文通过搭建试验台架测试执行机构内部气压的变化与位移变化的关系,采用新的控制算法提高了离合器控制精度。Mainly contains the original in the electronically controlled automated mechanical transmission,clutch actuator,electronic control unit for MT ontology,optional shift actuators and sensors,in the field of commercial vehicle,the clutch actuator is widely used,the actuator has a good adaptability to the work environment,action quick,workload is big,can adapt to the advantages of the application of the high torque output,but the pneumatic actuators are the main disadvantages of slow response and poor control precision,puts forward higher requirements on control technology,this paper build test bench testing displacement change with the change of air pressure inside the actuator,and the clutch control precision is improved based on the new control algorithm.
