Abstract
A method is disclosed. The method includes measuring at least one electrical parameter (R, L, C) of at least one wire (10) in a motor vehicle (100) at a certain time instance (ti) to obtain measurement data (M(ti)); comparing the measurement data (M(ti)) with comparative data (C(ti)) held in a data storage (5); and taking a predefined action (63) dependent on the comparing.
Claims18
A method comprising:
- measuring a resistance of a wire in a motor vehicle at a certain time instance to obtain measurement data for the resistance of the wire, wherein the wire is connected in series with an adjustable wire protector configured with a first set of trip data, wherein the wire is coupled to a power source, wherein the adjustable wire protector is further configured to disconnect the wire from the power source when a current through the wire reaches a predefined current threshold, and wherein the predefined current threshold is set to a first current level of the first set of trip data when the adjustable wire protector is configured with the first set of trip data;
- comparing the measurement data for the resistance of the wire with comparative value data held in a data storage;
- determining whether the wire fails an integrity check based on the comparing of the measurement data for the resistance of the wire with the comparative value data;
- determining, in response to a determination that the wire failed the integrity check, a second set of trip data based on the comparing of measurement data for the resistance of the wire;
- and
- setting the adjustable wire protector using the second set of trip data, wherein setting the adjustable wire protector using the second set of trip data comprises reducing the predefined current threshold to a second current level of the second set of trip data and wherein the second current level is less than the first current level.

Adaptable wire protection circuitry comprising:
- an adjustable wire protector connected in series with a wire, wherein the adjustable wire protector is configured with a first set of trip data, wherein the wire is coupled to a power source, wherein the adjustable wire protector is further configured to disconnect the wire from the power source when a current through the wire reaches a predefined current threshold, and wherein the predefined current threshold is set to a first current level of the first set of trip data when the adjustable wire protector is configured with the first set of trip data;
- and
- a measurement and calculation circuit configured to:
- measure a resistance of a wire in a motor vehicle at a certain time instance to obtain measurement data for the resistance of the wire;
- compare the measurement data for the resistance of the wire with the comparative value data held in a data storage;
- determine whether the wire fails an integrity check based on the comparison of the measurement data for the resistance of the wire with the comparative value data;
- determine, in response to a determination that the wire failed the integrity check, a second set of trip data based on the comparing of measurement data for the resistance of the wire;
- and
- set the adjustable wire protector using the second set of trip data, wherein, to set the adjustable wire protector using the second set of trip data, the measurement and calculation circuit is configured to reduce the predefined current threshold to a second current level of the second set of trip data and wherein the second current level is less than the first current level.
