A method for power saving in a steering system of a motor vehicle including a road wheel actuator acting on a rack to turn steerable road wheels and a controller configured or programmed to generate an operation signal for the road wheel actuator, wherein the controller includes a position controller to generate a motor torque request based on an actual and/or a measured position of the rack and a requested rack position, includes detecting a passive mode of the steering system by a passive mode detector of the controller if the motor vehicle is stopped and no steering input is provided, and if a passive mode is detected by the passive mode detector, setting the motor torque request to zero in order to save power.

Power saving mode for steering systems of a motor vehicle

A method can be utilized to reduce the kinetosis effect in passengers of motor vehicles having an autonomous and/or semi-autonomous driving mode. By means of a display unit, an image generated from image data is displayed to at least one passenger in a display area of the display unit while the motor vehicle is moving. The method may involve estimating a future change in an acceleration of the motor vehicle and modifying the image data based on the estimated future change in acceleration by way of a correction algorithm such that an effect of a relative movement between the displayed image and the passenger is reduced.

Method for reducing the kinetosis effect for passengers of motor vehicles observing an image displayed on a display unit

A method for operating an electromechanical steering system for a motor vehicle with variable chassis height, with a steering rack, which is driven by a servo motor through a recirculating ball screw drive, with a control unit, which receives input signals and generates output signals for driving the servo motor, the output signals being representative of an assist torque to be provided by the steering system, may be characterized in that, in operation, the control unit may receive or generate a chassis height signal that may indicate a current chassis height of the vehicle, and may limit the assist torque, on the basis of the chassis height signal, to an upper limit, wherein the upper limit may be decreased with an increase of the difference between the current chassis height and a mean chassis height.

Steering system with overload protection

An electric power steering system may be controlled by superimposing a driver demand and a driver assistance device demand value to calculate a driver requested support value, in which a virtual driver support value may be calculated based on driver demand and a correction driver support value may be calculated based on a driver assistance device demand value, and the driver requested support value may be calculated as a combination of the virtual correction driver support value and the virtual driver support value.

Control in an electric steering system

The invention refers to a steering device and a method for controlling a steering device with steering power support means for a motor vehicle with at least one steerable road wheel.

Controlling method for a steering system

A method for controlling a steering device with steering power support means for a motor vehicle with at least one steerable road wheel, where the steering device may include a steering shaft with a first end to adopt a steering wheel, a control device controlling said power support means, sensing means detecting steering shaft torque introduced in said steering shaft, and means to determine a hands-off situation in which the driver does not introduce a torque into said steering shaft, wherein the steering power support means support the driver on the basis of a driver demand introduced into the steering shaft, may comprise determining a steering wheel torque on basis of the steering shaft torque; determining a time derivative of the detected steering wheel torque; if the absolute value of the steering wheel torque is lower than a threshold torque limit and if the absolute value of the derivative of steering wheel torque is lower than a threshold derivative torque limit, a counter is increased by one count; if the absolute value of the steering wheel torque is higher or equal than a threshold torque limit, or/and if the absolute value of the derivative of steering wheel torque is higher or equal than a threshold derivative torque limit&#x2212;, said counter is decreased by one count; and if said counter has a value equal to or higher than a threshold count limit the hands-off state is determined.
