Claim 6:
7. The vehicle hydraulic pressure control method of claim 5, wherein the hydraulic state data comprises first oil pressure data of the high-pressure control oil circuit in the hybrid working mode, and
the dynamically adjusting the working state of the vehicle hydraulic control system according to the hydraulic state data and the preset adjustment strategy comprises:
controlling the high-low pressure decoupling valve to be in a coupled state, and collecting second oil pressure data in the coupled state, if the first oil pressure data of the high-pressure control oil circuit does not meet a preset oil pressure data; and
adjusting a rotational speed of the mechanical pump, a rotational speed of the electronic pump or a current of the main pressure regulating pilot solenoid valve, if the second oil pressure data does not meet the preset oil pressure data.
