Publication number: 20200232859Abstract: Method for detecting the presence of a drivers hands on the steering wheel 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. A sum of a torque with which the driver acts on the steering wheel and a counter-torque generated by friction in the upper part of the steering system is estimated by means of a Kalman Filter. In addition, the counter-torque is estimated, and the estimated sum of the torque and the counter-torque are used to determine whether the drivers hands are on the steering wheel.Type: ApplicationFiled: May 15, 2018Publication date: July 23, 2020Applicant: TRW Automotive GmbHInventors: Emad Farshizadeh, Tobias Oesterwind, Amo Luengen, Dirk Zimmermann
