Abstract EN
An electric oil pump (EOP) was integrated into the hydraulic system and an automatic transmission (AT) mechanical oil pump (MOP) was downsized.
These processes were performed to combine a start-stop function with the AT and further improve the transmission efficiency.
Furthermore, this study established a dynamics model of power loss and leakage of an 8-speed AT; a flow-based control algorithm of the EOP was then developed to realize the start-stop function and support the MOP to meet the flow requirement of the system.
Based on a driving simulation method, sizes of the MOP and EOP that ensured optimal fuel economy were selected.
A control strategy for the starting clutch was also developed to minimize the starting delay of the test vehicle.
A test environment on a rig and prototype vehicle was established to verify the feasibility of the proposed control strategies.
The test results indicated that the transmission functioned favorably with the novel two-pump system presented, and a quick and smooth starting performance was achieved when the engine was restarted.
The findings in this study are extremely valuable for forward designs of an AT for realizing start-stop function and improving efficiency.
