摘　　要：在AMT商用车行驶过程中,离合器的控制决定了整车的舒适性。为了研究离合器在车辆换挡过程中的工作状态,基于LPC1768芯片开发了离合器助力缸的气压以及控制信号PWM采集设备,并且进行了测量系统的实车测试验证。测试结果表明:所开发的测量系统可以准确地采集离合器助力缸的缸内气压变化,并且成功还原了换挡过程中离合器的PWM控制过程。In the driving process of commercial vehicle equipped with AMT, the control of clutch determines the comfort of the vehicle. In order to study the working state of clutch in the process of gear shift, an acquisition device of air pressure of clutch booster cylinder and PWM control signal based on LPC1768 is designed, and it is tested and verified in real car. The test results show that the measurement system can accurately collect the pressure change in the pneumatic clutch booster cylinder, and successfully restore the clutch PWM control process in the shift process.
