Abstract: Due to the wide application of manual mechanical transmission in heavy vehicles, in the control process of the transmission system, human-computer interaction is frequent, and the unreasonable control system will not only affect the performance of the whole vehicle, but also increase the driver's work intensity and affect the driving experience. From the perspective of ergonomics, this paper analyzes and discusses the layout of the clutch pedal, the control and adjustment of the key points of the pedal stroke and the clutch pedal force, aiming to improve the comfort of the clutch control system and provide some improvement schemes for improving the performance of the clutch control system.
