Patent ID: 7121138

Claim:
An apparatus for detecting a tire deformation of a vehicle tire, comprising: a tire pressure sensor for sensing a tire pressure; a signal processor configured to provide a signal indicating the tire deformation based on a difference between the tire pressure at a first time and the tire pressure at a second time, wherein the signal processor comprises a unit for determining a tire pressure average value and for providing a value based on the tire pressure average value; a unit for sensing a difference between the value and a further value, wherein the further value is based on the tire pressure at the second time; and a unit for providing the signal indicating tire deformation on the basis of the difference, wherein the tire pressure at the second time is larger than the tire pressure average value at the first time due to a tire deformation, and wherein the unit for providing the signal indicating the tire deformation is configured to provide the signal indicating the tire deformation at the second time, if the difference between the value and the further value exceeds a predetermined value.
