A haptic operating device for vehicles. The device has a rotatable operating part, a magnetic field source, and a magnetorheological braking device for braking a rotational movement of the operating part. The magnetorheological braking device has two braking components which can be rotated relative to one another and one of which is coupled to the rotatable operating part. The second brake component, acting as an outer brake component, surrounds the first brake component that acts as an inner brake component. A closed magnetorheological brake chamber is provided with a magnetorheological medium and is formed between the two brake components and has a peripheral braking gap.

A magnetorheological braking device for setting operating states by way of rotational movements has an axle unit and a rotary body rotatable about the axle unit. The rotatability of the rotary body can be decelerated and/or blocked by a magnetorheological braking apparatus. A sensor apparatus has a magnetic ring unit and a magnetic field sensor for sensing a magnetic field of the magnetic ring unit. A shielding apparatus at least partially shields the sensor apparatus from a magnetic field of a coil unit of the braking apparatus. The shielding apparatus includes a shielding body surrounding the magnetic ring unit and a separating unit between the shielding body and the magnetic ring unit, and having a magnetic conductivity multiple times lower than the shielding body. A holding apparatus connects the shielding apparatus to the rotary body in an at least partially rotationally fixed manner.

Magnetorheological braking device, in particular operating apparatus

A magnetorheological braking device with a fixed holder and a first and second braking component. One of the braking components is connected to the holder and does not rotate relative thereto. The two braking components are continuously rotatable relative to one another. The first braking component extends axially, and the second braking component has a hollow shell part extending around the first braking component. A peripheral gap, filled with a magnetorheological medium, is formed between the first and second braking component. The first braking component has an electric coil and a magnetically conductive core extending axially. Magnetic field concentrators, on the core and/or the shell part, protrude into the gap, creating variable gap height. The electric coil is wound around a section of the core. A magnetic field of the electric coil runs through the core, magnetic field concentrators, and the gap into a wall of the shell part.

A device component has a magnetorheological brake device with a static holder and with two brake components. A first brake component is rotationally fixedly to the holder and extends in an axial direction. A second brake component has a hollow, rotary part which is rotatable about the first brake component. An encircling gap between the first and second brake components is filled with a magnetorheological medium. The first brake component has a core of magnetically conductive material which extends in the axial direction. An electrical coil is wound axially around the core and spans a coil plane. A magnetic field of the coil extends transversely through the first brake component. A maximum outer diameter of the electrical coil in a radial direction within the coil plane is greater than a minimum outer diameter of the core in a radial direction transversely to the coil plane.

Device component having a magnetorheological brake device

An operating system with an operating device and an interface device. The operating device has a receiving part and an operating element movably mounted on the receiving part relative to the receiving part for performing an input. A movement resistance for the movability of the operating element is set based on a relative position of the operating element by a controllable braking device and considers a stored assignment between relative positions and movement resistances. The assignment is adjustable via interface device. The interface device displays a coordinate system with default points for a setting range that can be positioned by an input means. The interface device creates a curve, which runs in accordance with the default points, and the interface device displays the curve on the user interface and determines the assignment based on the shape of the curve.

Operating system with at least one operating device and with at least one interface device and method for operating an operating system

A method and an assembly for pivoting a movable component having a drive device with an electric drive motor in order to influence a pivoting of the component between a first setting and a second setting. A position sensor detects a position measure for a setting of the component and a speed parameter for a displacement speed of the component. During a displacement of the component with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. The setpoint voltage is increased if a current intensity flowing through the drive motor is lower than the electrical setpoint current intensity, and the setpoint voltage is reduced if the current intensity flowing through the drive motor is higher than the electrical setpoint current intensity.

Assembly and method

A device component has a magnetorheological braking apparatus with a stationary holder and at least two brake components. One of the two brake components is connected to the holder for conjoint rotation and extends in the axial direction. The two brake components can be rotated relative to each other. The second brake component has a hollow sleeve part and surrounds the first brake component. A closed chamber is formed between the brake components. The second brake component is rotatably accommodated on the first brake component at a first end of the closed chamber. The closed chamber is substantially filled with a magnetorheological medium. A magnetic-field generator forms a magnetic field to influence the medium in the closed chamber. The second brake component is axially slidable on the first brake component to change a volume of the closed chamber to compensate for temperature-related and/or leakage-related volume changes.

A door component for pivoting a movable door of a motor vehicle has a drive with an electric drive motor in order to influence a pivoting of the door between a closed setting and an open setting. A position measure for an angular setting of the door leaf and a speed parameter for an angular speed of the door leaf are detected by a position sensor. During a pivoting of the door leaf with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. Then the current intensity flowing through the drive motor is ascertained. The setpoint voltage is increased if the current intensity is lower than the electrical setpoint current intensity, and the setpoint voltage is decreased if the current intensity is higher than the electrical setpoint current intensity.
