Actuation method for a hydraulic system with a pump and multiple valves, and hydraulic system

A method of controlling a hydraulic system, the hydraulic system including an electrically driven pump and a plurality of regulator valves feeding corresponding consumers, the method comprising:

• in response to a total flow demand rising above an upper flow threshold, operating in an enhanced mode in which
• the pump is driven with a first current level, and
• the regulator valves are held steady until a system pressure exceeds a first pressure threshold, after which the regulator valves are operated based on pressure demands of the respective consumers;
• and
• in response to the total flow demand falling below a lower threshold, operating in a normal mode in which
• the regulator valves are operated based on the pressure demands of the respective consumers,
• the pump is driven with the first current in response to the system pressure falling below a lower pressure threshold, and
• the pump is turned off in response to the system pressure rising above an upper pressure threshold.

A method for actuating a hydraulic system for an actuation device of a motor vehicle, wherein the hydraulic system has a pump, multiple valves each arranged between a system rail connected to a pump outlet and at least one hydraulic consumer, wherein the pump is switched between a normal operation and an enhanced operation according to an existing total energy demand of the at least one hydraulic consumer, wherein, in normal operation, an existing system pressure in the system rail is determined at regular time intervals and a target pressure of the system rail is calculated, and an upper pressure threshold and a lower pressure threshold are established on the basis of the target pressure, wherein the pump is driven when the system pressure is below the lower pressure threshold and switched off when the system pressure is above the upper pressure threshold, and wherein, in the enhanced operation, the pump is continuously driven and each of the valves is operated according to an individual energy demand of the respective hydraulic consumer after the system pressure achieves a threshold value, wherein the upper pressure threshold is calculated using a first load factor based on the target pressure and the lower pressure threshold is calculated using a second load factor based on the target pressure, wherein the at least one load factor is a fixed constant or a temperature-dependent and/or system pressure-dependent variable.
