Abstract (en)
[origin: US7941290B2] In a method for error containment and diagnosis in a fluid power system the fluid volumetric flow in the overall system or at least a part thereof and the fluid pressure (P) is detected as a measurement quantity in each case during a duty cycle and is compared with stored references. 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 component or at which components (10 through 14) of the system an event has occurred influencing fluid consumption in order to recognize same as subject to error. Guide value quantities (Q/P) are derived from the respective volumetric flow values (Q) and the measured pressure (P) and are integrated or summated over the duty cycle to form guide values (KD), a corresponding guide value reference curve (KDref) as a reference being chosen from a stored selection matrix, which has the guide value reference curves (KDref) or time dependent guide values for different operating conditions.
