Patent ID: 8494704

Claim:
A system for indirect tire pressure monitoring of tires of a vehicle, comprising: a tire classification database indicating at least one classified tire type being classified with respect to wheel speed spectrum data and/or tire force spectrum data; a vehicle tire type determination unit being adapted to determine a vehicle tire type for the vehicle on the basis of vehicle data in including information on at least one tire currently used with the vehicle, wherein the vehicle tire type determination unit is adapted to perform wheel speed spectrum and/or tire force spectrum analysis to obtain a wheel speed spectrum data and/or tire force spectrum data for the at least one tire; an association determination unit being adapted to determine whether the vehicle tire type can be associated to one of the at least one classified tire type, wherein the association determination unit is adapted to determine whether the tire classification database includes data indicating a tire type having wheel speed spectrum data and/or tire force spectrum data being at least comparable with the wheel speed spectrum data and/or tire force spectrum data; and a tire pressure monitoring unit being adapted to, in the case an association is determined, monitor tire pressure according to the associated classified tire type, wherein, in the case the association determination unit fails to associate the vehicle tire type to one of the at least one classified tire type, the tire pressure monitoring unit is adapted to perform tire pressure monitoring on the basis of at least one of a default parameter setting and a default operation mode.
