The hydraulic control unit assembly of the 7-speed wet dual-clutch transmission (DCT) is one of its core subsystems, mainly responsible for achieving precise control and efficient operation of the transmission through hydraulic principles. Its specific functions include the following key functions:

---

1. Clutch control
- ** Dual-clutch switching ** : The engagement and disengagement of two sets of multi-plate clutches are controlled by hydraulic pressure to achieve seamless switching between odd gears (1, 3, 5, 7) and even gears (2, 4, 6), avoiding power interruption.

- ** Pressure Regulation ** : Dynamically adjust the clutch clamping force according to driving requirements (such as sudden acceleration and coasting) to balance smoothness and response speed.
