Abstract
A system for determining a tire change status in a vehicle is provided. The system includes at least one processing device and a storage device. The at least one processing device may be arranged to: calculate a value of at least one reference parameter which may be used in indirect tire pressure monitoring; store the calculated value of said at least one reference parameter in the storage device; retrieve a previously stored value of said at least one reference parameter from the storage device; determine a similarity parameter based on a similarity between the calculated value and the previously stored value of said at least one reference parameter; and determine a tire change status, indicating whether or not the tires have been re-filled or replaced, by comparing said similarity parameter with a threshold.
