Problems solved by technology
[0002] The wet clutch switching and control of the automatic transmission is realized through the hydraulic system. The hydraulic control system receives the control signal of the TCU, controls the disengagement and engagement of the clutch by adjusting the oil pressure, and at the same time cools and lubricates the clutch to meet the automatic control requirements of the vehicle. , the existing clutch hydraulic control branch switches the flow direction of the oil circuit through a pressure control valve. However, when the clutch pressure control valve fails, the clutch cannot be disengaged, which poses a safety hazard
