Abstract

A method for controlling a hydraulic system of a machine having a machine control system is disclosed. The hydraulic system includes at least one hydraulic output having an output element which can be controlled by way of activation variables and whose state can be described by state variables. The method includes registering the at least one hydraulic output, wherein registration data of the at least one hydraulic output is captured, wherein the registration data includes data concerning the activation variables and the state variables, and wherein the state variables include output state variables which describes the state of the output element of the at least one hydraulic output. The method further includes transmitting one or more data concerning the output state variables of the at least one hydraulic output to the machine control system. In addition, the method includes receiving from the machine control system a target preset for at least one of the output state variables of the at least one hydraulic output. The method also includes determining activation values for the activation variables of the at least one hydraulic output based on the target preset and activating the at least one hydraulic output with the activation values.

First claim

What is claimed is:

1. A method for controlling a hydraulic system of a machine having a machine control system, wherein the hydraulic system includes at least one hydraulic output having an output element configured to be controlled by way of activation variables and whose state can be described by state variables, the method comprising:
registering the at least one hydraulic output, wherein registration data of the at least one hydraulic output is captured, wherein the registration data includes data concerning the activation variables and the state variables, and wherein the state variables include output state variables which describes the state of the output element of the at least one hydraulic output;
transmitting one or more data concerning the output state variables of the at least one hydraulic output to the machine control system;
receiving from the machine control system a target preset for at least one of the output state variables of the at least one hydraulic output; and
determining activation values for the activation variables of the at least one hydraulic output based on the target preset and activating the at least one hydraulic output with the activation values,
wherein when determining the activation values, at least one first actual value is captured for the at least one of the output state variables, and
wherein the activation variables are determined by way of an adjustment method, such that the at least one first actual value is adjusted according to the target preset for the at least one of the output state variables.

2. The method according to claim 1 , further comprising:
after the registration, configuring the at least one hydraulic output,
wherein configuration activation values for the activation variables of the at least one hydraulic output are determined based on the registration data, and
wherein the at least one hydraulic output is activated according to the configuration activation values so as to be brought into a configuration state.

3. The method according to claim 1 , wherein upon registration of the at least one hydraulic output:
the registration data is received as registration data sent from the at least one hydraulic output; and/or
an identifier of the at least one hydraulic output sent from the at least one hydraulic output is received, and the registration data is queried from a memory of a hydraulic control system and/or a memory of a remote computing unit.

4. The method according to claim 1 , wherein the target preset comprises at least one target value and/or at least one target trajectory for the at least one of the output state variables.

5. The method according to claim 1 , wherein:
when determining the activation values, at least one second actual value is captured for at least one further state variable, and
in the adjustment method, the at least one second actual value is considered.

6. A hydraulic control system for a hydraulic system configured so as to carry out all steps of the method according to claim 1 .

7. The method according to claim 1 , wherein a computer program comprises instructions that, when the computer program is executed by a computer, prompt the computer to carry out the method.

8. A computer-readable disk on which the computer program according to claim 7 is stored.

9. A method for controlling a hydraulic system of a machine having a machine control system, wherein the hydraulic system includes at least one hydraulic output having an output element configured to be controlled by way of activation variables and whose state can be described by state variables, the method comprising:
registering the at least one hydraulic output, wherein registration data of the at least one hydraulic output is captured, wherein the registration data includes data concerning the activation variables and the state variables, and wherein the state variables include output state variables which describes the state of the output element of the at least one hydraulic output;
transmitting one or more data concerning the output state variables of the at least one hydraulic output to the machine control system;
receiving from the machine control system a target preset for at least one of the output state variables of the at least one hydraulic output; and
determining activation values for the activation variables of the at least one hydraulic output based on the target preset and activating the at least one hydraulic output with the activation values,
wherein the hydraulic system comprises a pressure supply system which is configured to be controlled by way of supply activation variables and whose state can be described by supply state variables, and
wherein the method further comprises determining supply activation values for the supply activation variables based on the target preset and/or the activation values.

10. The method according to claim 9 , further comprising:
registering the pressure supply system, wherein supply registration data of the pressure supply system is captured, and wherein the supply registration data comprises data concerning the supply activation variables and the supply state variables; and
configuring the pressure supply system, wherein supply configuration activation values for the supply activation variables are determined based on the supply registration data, and wherein the pressure supply system is activated according to the supply configuration activation values so as to be brought into a supply configuration state.
