摘要
Procedure for determining a pressure deviation (pRel) between a theoretical tire pressure (pIdeal) and a current tire pressure (pActual) for a tire (5) of a vehicle (10), the steps of which comprise. determine a wheel load (f) for the tire (5), determine a tire dynamic radius (rdin) of the tire (5), and determine the pressure deviation depending on the wheel load (f) and dynamic radius of the tire (rdin), specifying an unloaded tire radius (r0) of the tire (5) in the unloaded state, where the current tire pressure (pActual) is calculated based on the wheel load (f), the radius of the unloaded tire (r0) and the dynamic radius of the tire (rdin) by means of a tire stiffness function.
