1. A device for determining a side position of wheels of a motor vehicle during cornering, comprising:

  • a plurality of sensor devices each mounted to a corresponding tire of a respective individual wheel for detecting a mechanical deformation of the corresponding tire upon the corresponding tire rolling forward on a road surface, said sensor devices supplying deformation data and converting deformation energy into electrical energy;

    electronic wheel units each connected by signal to a respective one of said sensor devices and at least partially operating on the electrical energy generated by said sensor devices; and

    a central evaluation device connected by signal to said electronic wheel units for receiving the detected deformation data and for determining side positions of the individual wheels during cornering of the vehicle from contact area lengths determined from the deformation data.
