Abstract:
1. A device for measuring a tread depth of a motor vehicle tire, the device comprising: at least one sensor element configured for acquiring data relating to a change in a deformation characteristic of the motor vehicle tire in a region of a tire contact area when said sensor element is permanently mounted to an inner side of the motor vehicle tire opposite the tread; and a control and evaluation unit having a data connection configured for receiving the data acquired by said at least one sensor element and for further processing the acquired data, said control and evaluation unit configured to determine the tread depth of the motor vehicle tire based on a degree of bending of a tread of the motor vehicle tire, wherein the degree of bending of the tread of the motor vehicle tire is indicated by the data acquired by said at least one sensor element; and a wheel electronic system electrically connected to said at least one sensor element and configured for transmitting tire identification data to said control and evaluation unit.
