Shift vibration would appear in gear shifting process of hydraulic-based AMT system, especially in the up-shift process from even-numbered gear or the down-shift process from the odd-numbered gear with X-Y type transmission box. The principle of gear shift in hydraulic system is analyzed as well as the reason of shift vibration is presented in this paper.(More)
A transmission control unit (TCU) based on the SOPC technology was designed, using a large-scale FLASH-based FPGA with analog channels. The functions of TCU are reasonable distributed between hardware and software for both of them being programmable. IP modules including the open-source cores and custom modules are integrated into FPGA in hardware design as(More)
