Shifting force control of an AMT heavy-duty truck based on manual shift test

Taking a heavy-duty truck as a research platform, the changing characteristics of shifting force, shift time, and slipping work are obtained through theoretical analysis and manual shift test of a real vehicle. Based on the analysis of the test results, a gear-shifting control strategy of the hydraulic automated shift control system is designed and experimentally verified on the bench. By optimizing the control parameters of high-speed switching valves, a control strategy and parameters are obtained, which can meet the requirements of dynamic performance and reliability.
