Abstract
Abstract A vehicle tire for a motor vehicle has a carcass, a belt, and tire tread. A device for generating data for determining tire-road adhesion or friction between the footprint of the vehicle tire and the road surface is provided. The device includes at least one magnetic sensor connected to a evaluation device. The at least one magnetic sensor has individual magnetic sensor elements forming cooperating sensor element pairs. The device also includes a magnetic field arranged in the belt and generated during tire manufacture by partial magnetization of the belt. The at least one magnetic sensor is arranged in at least one lug of the tire tread.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A vehicle tire for a motor vehicle comprising: a carcass, a belt, and a tire tread; a device for generating data for determining friction between a foot print of said vehicle tire and a road surface; said device comprising at least one magnetic sensor connected to an evaluation device; said at least one magnetic sensor comprised of individual magnetic sensor elements forming cooperating sensor element pairs; said device further comprising a magnetic field for each one of said magnetic sensors, wherein said magnetic field is arranged in said belt and generated during tire manufacture by partial magnetization of said belt opposite said at least one magnetic sensor in a radial direction of said vehicle tire; said at least one magnetic sensor arranged in at least one lug of said tire tread.
