Claim 5:
6. The vehicle hydraulic control method of claim 5, wherein the executing a hydraulic control strategy corresponding to a target working mode in the target working mode, to control the vehicle hydraulic control system to work comprises:
adjusting a current of a main pressure regulating pilot solenoid valve on a high-pressure control oil circuit, so that a main oil pressure that meets a pure electric working mode is established in a high-pressure control oil circuit, if the target working mode is the pure electric working mode; and
controlling a high-low pressure decoupling valve to be in a coupled state, so that the electronic pump is communicated with the high-pressure control oil circuit to supply oil to the high-pressure control oil circuit and a low-pressure cooling and lubricating oil circuit.
