A selection controller for manual selection of an operating mode and/or operating characteristics of an audio control device is disposed within an interior of a vehicle. The selection controller includes a selector element that is designed to allow a user to make the manual selection. The selecting element can be arranged at least in a first position that is not elevated from a control surface of the audio control device and in a second position that is elevated from the control surface of the audio control device.

Emergency hand crank drive consisting of a load shaft that is to be made to rotate, and a crank arm hingedly connected to said load shaft, and a coupling piece on said load shaft and a catch, which is fixedly connected to said crank arm and which has a shape that is complementary to the shape of said coupling piece and which can be releasably connected to said coupling piece, whereby a rotary sliding piece is mounted on said load shaft in such a way as to be movable in the longitudinal direction of said load shaft and be rotatable around the longitudinal direction thereof and said crank arm is hingedly secured to said rotary sliding piece.

A control knob for controlling the operation of a component of a household appliance is disclosed. The control knob includes a body configured to be attached to a rotatable rod extending from the appliance. A locking element reversibly secures the body in at least one rotational position. The locking element is movable between a first position and a second position. The locking element is configured to engage with a notch to rotatably secure the body in the at least one rotational position when the locking element is in the first position, and to disengage from the notch to permit the body to be rotated when the locking element is in the second position.

An operating panel device includes an operating ring, and a display device which is disposed to face a back surface of the operating ring. The display device includes a first portion, a second portion, and a third portion. The first portion is located inside the operating ring, and the second portion is located outside the operating ring. The third portion connects the first portion and the second portion. A display of the first portion changes in conjunction with a rotational operation applied to the operating ring.

A control knob for an appliance includes a base having an axially-operated switch. An outer control assembly is rotationally and axially operable with respect to the base. An inner display assembly is rotationally fixed with respect to the base and axially fixed with respect to the outer control assembly. The inner display assembly is biased toward an extended state and is axially operable to a selection state that engages the axially operated switch.

A haptic interface, including: a button which can be rotated by a user; an interaction element interacting with a magnetorheological fluid, secured to the button; a mechanism measuring a current position of the button; a brake including a magnetorheological fluid and a generation system to generate a magnetic field in the fluid; a controller configured to generate orders for the system to generate a magnetic fluid to modify a value of the magnetic field; and a mechanism to detect torque exerted by a user on the button to know direction of the torque and whether the torque is greater than a given value for a given direction, the controller controlling generation of a magnetic field based on obtained information about the torque at least when the button indicates zero or low speed.

A driving support apparatus supports driving of the vehicle. The driving support apparatus includes a brake pedal detection unit, a retraction speed calculation unit and a driving operation device setting unit. The brake pedal detection unit detects an operation amount of the brake pedal. The retraction speed calculation unit calculates a retraction speed of the brake pedal, based on the operation amount of the brake pedal detected by the brake pedal detection unit. The driving operation device setting unit sets a reaction force exerted by a driving operation device to a larger value as the retraction speed calculated by the retraction speed calculation unit becomes higher.
