Claim 0:
1. An electronic anomaly detection unit for use in a vehicle, the electronic anomaly detection unit comprising:
a selection component configured to monitor a current configuration of the electronic anomaly detection unit, wherein the current configuration of the electronic anomaly detection unit changes with a change in state of the vehicle,
wherein the selection component is configured to select a state parameter for monitoring from a plurality of stored state parameters based on the current configuration of the electronic anomaly detection unit;

an association component configured to select a predefined value range from a plurality of predefined value ranges based on the current configuration of the electronic anomaly detection unit and associate 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 electronic anomaly detection unit,
a counter associated with a counter threshold that is configurable, 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,
wherein the association component is configured to configure the counter threshold by selecting a counter threshold value for the counter threshold based on the current configuration of the electronic anomaly detection unit corresponding to the selected state parameter, wherein the counter threshold value changes with a change in the current configuration of the electronic anomaly detection unit;

an input component configured to receive 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; and
a decision component configured to compare the input value to the selected predefined value range, increase 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, compare the counter value of the counter to the selected counter threshold value, and generate an anomaly error signal when the counter value of the counter is equal to the selected counter threshold value,
wherein one or more of the input component, the selection component, the association component, and the decision component are implemented in hardware.
