Abstract

The invention relates to the field of vehicle engineering and provides a hydraulic control system and an automobile. The hydraulic control system comprises a first oil pump, a second oil pump, a control device and a system overflow valve, the first oil pump and the second oil pump are connected with a clutch through the control device, and the system overflow valve is connected with the first oilpump. After an opening signal is received, the control device controls the first oil pump and the second oil pump to communicate with the clutch to provide combination required hydraulic force for theclutch; when the opening signal is not received by the control device, the first oil pump is connected with the system overflow valve to realize pressure relief. The second oil pump is used for connection with a cooling system of the clutch. The hydraulic control system is used for providing the combination required hydraulic force for the clutch to enable normality in operation of the clutch, the response speed of the clutch can be increased, operating effects of the clutch are improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a hydraulic control system and an automobile. Background technique [0002] Hybrid power transmission is one of the important development directions at present, and various domestic enterprises have also invested more manpower and material resources in research and development. Electro-hydraulic control system is the main control scheme adopted by hybrid power system at present. Generally speaking, the tasks to be completed by the hydraulic control system mainly include two main parts, namely: lubrication of components, heat dissipation of motors and batteries; control of wet clutches (mainly through the combination and separation of wet clutches to realize the switching of different power sources and combinations). [0003] The above two functional requirements are significantly different for the pressure demand level of the hydraulic system. If the system pressure of the hy...
