Abstract
A method for detecting the presence of a driver's hands on the steering wheel of a motor vehicle is described. By means of a mathematical model, at least one part of a steering system of the motor vehicle is modeled. In addition, a rotational angle of a lower end and/or an upper end of a torsion bar of the steering system is determined. A torque acting on the torsion bar is determined by means of a measuring device and a total torque acting on the steering wheel and a rotational angle acceleration of the steering wheel are estimated by means of a Kalman Filter.
