Abstract

A device for generating a haptic signal in a vehicle is provided, in which a driver's command can be given via a rotary gas handle. A servo unit is formed in such a manner that, as a function of at least one detected operational condition for driving, a theoretical speed of the vehicle can be generated. Based on the theoretical speed of the vehicle, a servo signal for actuation of a servo element of the vehicle is generated, where the servo element is formed such that a restoring force for the rotary gas handle or the torque required for moving the rotary gas handle is adjusted thereby.
