“…With the development of hydraulic technology and control theory, fluid transmission and control technology is presenting new, vigorous development in the field of vehicles [1][2][3]. During the shifting of the vehicle, the friction elements in the shifting clutch undergo a slipping process during separation and engagement, which is inevitably accompanied by a torque disturbance, generating a corresponding shifting impact and affecting the stability of the shifting.…”

The clutch is currently developing towards high power, high stability, and intelligent operation. The traditional hydraulic buffering valve mostly uses a passive hydraulic buffer valve or a high speed on-off valve and a proportion valve. It has a single buffering characteristic and poor adaptability. It is difficult to meet the requirements. Therefore, a new theory and a new method are proposed. In the field of clutch oil pressure control, the 2D digital buffer valve is designed using 2D digital technology. The structure of the 2D digital buffering valve is described. Based on the working principle of the valve, a mathematical model is set up. MATLAB/Simulink is used to solve the model. The results are analyzed in this paper. Finally, a valve test platform is built and an experimental study carried out. The research indicates that the 2D digital buffering valve has a good static characteristic. The linearity is 9.25%, and the hysteresis is 0.106. The response time of the 2D digital buffer valve is about 55 ms, and the valve overshoot is only 18.62%. During shifting, the maximum deviation is 0.165 MPa, and the steady-state error is 0.056 MPa. Different buffer control signals as the input and the output of the valve can follow the input change. The experimental and simulation results are consistent. The rationality of the mathematical model has been verified.

“…A dynamometer is one of the important devices for performance and equipment testing in motor manufacturing and product R&D. It can be used to simulate and control the load of the tested motor so as to measure the torque, speed, current, voltage, power, efficiency, and other parameters of the motor, as well as for other special dynamic test items, such as safety test, dynamic balance test, NVH test (vibration/noise/life), etc. [1][2][3][4][5][6]. With the development of modern technology, in addition to conventional items such as motor speed, torque, voltage, and current, the requirements for the motor transient performance test are also increased [7][8][9][10].…”

In view of the problem that the traditional motor test system cannot directly test the transient parameters of the motor and the dynamic arbitrary load loading requirements during motor loading, as well as the high cost of implementation, this research uses STM32+FPGA as the core to form the main control of the motor test system unit, combining the superior control performance of the ARM processor and the high-speed data processing advantages of FPGA. FPGA and STM32 are controlled by the FSMC bus communication and data ping-pong algorithm. Using this method, a small-size control core board in the motor test system is manufactured. It can be embedded in the existing traditional dynamometer system to improve the dynamometer transient parameter test and the dynamic motor loading performance. The experimental results show that the system can basically meet the requirements of the motor transient test and dynamic loading, and can achieve the fastest data refresh rate of 1 ms when measuring the motor’s speed and torque, as well as arbitrary waveform loading within a 100 M sampling frequency, with a loading error of 0.8%. It satisfies the motor transient test and dynamic loading requirements.
