摘要： The invention is directed to a system, a method and a computer program including program code for carrying out the method, when executed on a processing system, of issuing a tire pressure deviation in a vehicle's tire. The system comprises a calculation unit (20) adapted to calculate temporally successive output signals (WRAx) indicative of a tire pressure condition in the vehicle's tire on the basis of temporally successive vehicle's signals. It further comprises a calibration unit (25) adapted to determine a calibration value (WRAcal/X) on the basis of a number of temporally successive output signals (WRAx) from the calculation unit (20). It further comprises a detection unit (30) configured to detect a tire pressure deviation in the vehicle's tire on the basis of further temporally successive output signals (WRAx) from the calculation unit (20) and the calibration value (WRAcal/X) from the calibration unit (25), after determination of the calibration value (WRAcal,x) by the calibration unit (25). The detection unit (30) is further configured to monitor the temporal developing of the number of temporally successive output signals (WRAx) and to detect a pressure deviation on the basis of the temporal developing before having received the calibration value (WRAcal,x) from the calibration unit (25).
