Claim 17:
18. A method for detecting an anomaly in at least one component of a vehicle, the method comprising:
monitoring a current configuration of an anomaly detection unit, wherein the current configuration of the anomaly detection unit changes with a change in state of the vehicle;
selecting a state parameter for monitoring from a plurality of stored state parameters based on the current configuration of the anomaly detection unit;
selecting a predefined value range from a plurality of predefined value ranges based on the current configuration of the anomaly detection unit and associating the selected state parameter with the selected predefined value range to form a first association, wherein the selected predefined value range defines a normal state of at least one component of the vehicle according to the current configuration of the anomaly detection unit;
selecting a counter threshold for a counter based on the current configuration of the anomaly detection unit that corresponds to the selected state parameter,
wherein the counter threshold is configurable and changes with a change in the current configuration of the anomaly detection unit,
wherein the counter is configured to monitor any one of the plurality of stored state parameters, and wherein the counter is configured to count a number of discrete events during which an anomaly associated with the selected state parameter occurs;

associating the selected counter threshold with the counter;
receiving an input value corresponding to the selected state parameter, wherein the input value contains state information for the at least one component of the vehicle;
comparing the input value to the selected predefined value range;
increasing a counter value of the counter for each instance the input value exceeds the selected predefined value range indicating an occurrence of the anomaly associated with the selected state parameter;
comparing the counter value of the counter to the selected counter threshold; and
generating an anomaly error signal when the counter value of the counter is equal to the selected counter threshold.
