Patent ID: 7917325

Claim:
A method for error containment and diagnosis in a fluid power system in which the fluid volumetric flow in the overall system or at least a part thereof or a quantity dependent thereon is detected as a measurement quantity in each case during a duty cycle and is compared with stored references and in each case at the point in time of a deviation or a change in the deviation from the reference it is determined at which a component or components of the system an event has occurred influencing fluid consumption in order to recognize same as subject to error, wherein, in the case of such a deviation or change in the deviation and simultaneous occurrence of several activities influencing the fluid consumption of several components an exclusion process is performed in which during following activities, in which at least one of such components is involved, in respective further examining steps an examination is performed as to whether in turn a deviation or change in the deviation occurs, in each of such further examining step the components involved being respectively excluded as not being subject to error from further examination, if no deviation or change in the deviation take place.
