Patent ID: 7520358

Claim:
A device for generating a haptic signal in a vehicle, in which a driver's command is given via a rotary gas handle, comprising: a restoring device for generating a restoring force acting on the rotary gas handle and a servo force generator for generating a servo force acting on the rotary gas handle in a direction of actuation inducing acceleration or deceleration; means for detecting at least one predefined operational condition for driving, where the predefined operational condition for driving is one that makes a change of the current speed advisable as a function of definite conditions; and a servo unit operatively configured such that, as a function of the at least one detected predefined operational condition for driving, a theoretical speed for the vehicle is generated and, based on the theoretical speed for the vehicle, a servo signal for actuating a servo element is generated, wherein the servo element is operatively configured to adjust, based on the servo signal, at least one of the restoring force for the rotary gas handle and the servo force acting on the rotary gas handle.
