N2 - Two-speed automatic transmission is one solution to increase the economic efficiency and dynamic performance of battery electric vehicles (BEV). Hydraulic control unit (HCU) is a key component in automatic transmissions, which determines the quality of shifting directly. Based on the structural scheme and shift logic of a two-speed dedicated electric vehicles transmission (2DET) with two wet clutches, we designs a 2DET hydraulic control unit composed of three subsystems: pressure regulating and flow control system, shift operated and control system and cooling and lubrication system. The results of the experiments, including the valve body bench test, transmission bench test and vehicle test, show that the design of hydraulic control unit meets the requirements.
