Date Aug. 7, 1997A method and an arrangement for controlling cable winding and unwinding in an electrically driven vehicle. In the method, cable winding and unwinding, respectively, are controlled on the basis of the position of driving and/or steering means of the vehicle. The arrangement comprises only one unwinding valve connected in series with a hydraulic motor, by which valve the counterpressure of the hydraulic fluid flowing through the hydraulic motor can be regulated during cable unwinding from the reel, and one unwinding valve respectively, by which the quantity of the hydraulic fluid coming to the hydraulic motor can be regulated during cable winding.
