Patent ID: 6999906

Claim:
A reconfiguration method for implementation in a computer system for compensating failures of a sensor system ( 1 ) with at least two observers, each observer being formed by at least one sensor ( 2 , 50 ) for measuring ( 12 , 22 ) system states of an application system ( 11 , 21 ) and by at least one system model ( 4 ) for estimating of system states of the application system, in order to make system states with a predetermined reliability available to an allocated data processing unit ( 14 , 24 ), said method comprising the following steps: (a) ascertaining failure states based on time related deviation values for a first observer by comparing of a number of states measured by said at least one sensor, with a state estimated by said at least one system model, (b) initiating at least one further observer in response to the reaching of a first threshold level of said deviations, said further observer having a number of past time steps for determining a failure status of the further observer, and (c) transmitting the system states ascertained by the further observer to the data processing unit ( 14 , 24 ) for further processing, as soon as the first observer has reached a second threshold value.
