Abstract

Official abstract text for this publication.

A method and a device generate haptic feedback for a vehicle driver, the haptic feedback being generated by applying an additional torque, which alternates about an average total steering torque, to a steering grip of a vehicle by way of an actuator. When the present haptic feedback is recognized and/or simultaneously when haptic feedback occurs, the actuator is actuated such that the magnitude of the average total steering torque is increased by a compensation torque.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method for generating haptic feedback for a vehicle driver of a vehicle, comprising: generating the haptic feedback by applying an additional torque, which alternates about an average total steering torque, to a steering grip of a vehicle by way of an actuator; and controlling the actuator, when the haptic feedback is present and/or simultaneously when the haptic feedback occurs, such that a magnitude of the average total steering torque is increased by a compensating torque. 2 . The method according to claim 1 , wherein the compensating torque is maintained, at least in part, until the end of the haptic feedback. 3 . The method according to claim 2 , wherein the compensating torque decreases to the value 0 at least by the end of the haptic feedback. 4 . The method according to claim 1 , wherein the compensating torque decreases to the value 0 at least by the end of the haptic feedback. 5 . The method according to claim 1 , wherein the haptic feedback warns the vehicle driver of leaving a driving lane. 6 . A steering system of a vehicle comprising a haptic feedback generator configured to execute: generating haptic feedback by applying an additional torque, which alternates about an average total steering torque, to a steering grip of a vehicle by way of an actuator; and controlling the actuator, when the haptic feedback is present and/or simultaneously when the haptic feedback occurs, such that a magnitude of the average total steering torque is increased by a compensating torque. 7 . The steering system according to claim 5 , wherein the haptic feedback is a vibration on the steering grip. 8 . The steering system according to claim 6 , wherein the actuator is one or both of a support motor and a servo motor.
