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.

Abstract
A device and a method for measuring the tread depth of a motor vehicle tire. The device includes at least one sensor element which is configured to acquire data on a change of the deformation characteristics of the motor vehicle tire in the area of the tire contact area and can be fixed in the area of the inner side of the motor vehicle tire opposite the tread; and a control and evaluation unit for evaluating and processing the acquired data. The unit is data-connected to the at least one sensor element.

13. A method of measuring a tread depth of a motor vehicle tire which comprises the following method steps:
-
providing at least one sensor element configured to acquire data relating to a change in a deformation characteristic of a motor vehicle tire in a tire contact region of the vehicle tire; mounting the at least one sensor element in a stable fashion on an inner side of the motor vehicle tire opposite the tread; acquiring data relating to a change in the deformation characteristic of the motor vehicle tire in the region of the tire contact region by way of the at least one sensor element; transmitting the data acquired by the at least one sensor element to a control and evaluation unit provided with a data connection to the at least one sensor element; transmitting, in addition to the data acquired by the at least one sensor element, a tire-specific identifier for associating the data with a given motor vehicle tire; and processing the data acquired by the at least one sensor element with the control and evaluation unit to determine the tread depth of the given motor vehicle tire based on a degree of bending of the tread of the given motor vehicle tire. - View Dependent Claims (14, 15, 16, 17, 18, 19, 21)
