  "textContent": "Tow bar arrangement () for interconnection of a pulling vehicle () and a pulled trailer (). The arrangement () comprises a control device () with a force sensor () arranged to sense an instantaneous relative force between vehicle () and trailer (). The control device () is arranged to produce a control signal for an electric motor () arranged to propel the trailer () so that a motor force counter-acts said measured force. The invention is characterised in that the control device () is arranged to a first time series of force measurements, in that the control device () comprises a low-pass filter () producing a second low-pass filtered time series, and in that a regulator () is ar-ranged to regulate said second time series to produce said control signal.",
