  • Patent number: 8958950
    Abstract: A method for variation of steering sensation in a steering arrangement of a vehicle, e.g. a truck, which steering arrangement comprises a steering column (115) via which rotary motion is transmitted between an operating device (100), e.g. a steering wheel (100), and a servo device (9120) of the steering arrangement. The method includes the steps of—varying the rotational resistance of the steering column (115) as regards the rotary motion and/or—varying the moment of inertia of the steering column (115) as regards the rotary motion and—activating the variation manually via an operator, e.g., the driver of the vehicle, and/or automatically. The invention relates also to a device for variation of steering sensation, a computer program for that purpose, a computer and a vehicle with this program.
