Electric oil pump control algorithm for a 6 speed AT based HEV is developed. To evaluate the performance of the EOP control algorithm, a bench tester of AT based 2-shaft parallel HEV is constructed. Using the bench tester, line pressure response is investigated with/without checkball at AT oil pump for various ATF temperature and EOP speed. In addition, performance of the EOP control algorithm is investigated for various ATF temperature and vehicle acceleration. It is found from the experimental results that the EOP control algorithm shows satisfactory performance except the very high temperature and very low acceleration, which requires the modification of the control gains.
