Abstract
A device and a method for determining a side position of wheels during cornering of a motor vehicle include a plurality of sensor devices each being installed at a tire of a wheel for detecting mechanical deformation of the tire when it rolls forward on a road surface. Electronic wheel units are each connected by signal to an assigned sensor device. A central evaluation device is connected to the electronic wheel units for receiving detected deformation data and determining the side positions of the individual wheels during the cornering of the vehicle, from contact area lengths determined from deformation data.
