Abstract  In order to meet the different controllable requirements of a new type of series-parallel hybrid transmission on the working states of its hydraulic system under different driving modes, a control strategy of hydraulic system working states and valve working states was designed based on the structures of this new type of series-parallel hybrid transmission and its hydraulic system. Through the establishment of Simulink control model in combined with rapid control prototyping technology and vehicle drum test, the correctness and reliability of the control strategy was verified. The test results showed that the control strategy could match various vehicle driving modes well and meet the control requirements of the transmission on its hydraulic system.

Key words： vehicle engineering      hybrid transmission      hydraulic system      control strategy
