Abstract

The present invention discloses a dual-clutch automatic transmission cooling and lubrication hydraulic control system and a vehicle. The dual-clutch automatic transmission cooling and lubrication hydraulic control system comprises a clutch lubrication control valve whose outlet end is connected with a clutch lubricating oil circuit, a gear lubrication control valve whose outlet end is connected with a gear and bearing lubricating oil circuit, the inlet end of the gear lubrication control valve being connected with the inlet end of the clutch lubrication control valve in parallel at the first common end, further comprises a mechanical pump and an electronic pump whose inlet ends are connected to an oil tank respectively. The outlet end of the mechanical pump and the outlet end of the electronic pump are connected in the second common end in parallel, and a cooler disposed between the first common end and the second common end. The dual-clutch automatic transmission cooling and lubrication hydraulic control system disclosed herein have a variety of working modes, reducing the defects such as large displacement of the mechanical pump when working alone.
