Compact, multi-function rotational controllers or switches that allow an operator of a vehicle to simultaneously view the status of a plurality of related functions, and to easily change or toggle the status of each of the functions. A multi-function controller of the present disclosure may include a rotatable central control dial that is at least partially surrounded by a visual indicator panel that indicates a current status for the functions that are controlled by the multi-function controller. The multi-function controller may include a selected function indicator that indicates which of the plurality of related functions is currently selected, control input hardware that receives operator input, and control circuitry that toggles the state of the selected function responsive to such operator input. The multi-function controller may include an “all functions off” function that allows the operator to simultaneously turn all of the related functions off via a single input action.

A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.

A utility vehicle includes an open driver section including a driver’s seat for a driver to sit on; a hermetically sealable space disposed in the driver section and having a door; and a terminal in the hermetically sealable space.

Disclosed is a display device including a display panel including a display area and a non-display area surrounding the display area; a back plate disposed on one face of the display panel and including a first ground path unit; and a heat-dissipation plate disposed on a back face of the back plate and including a second ground path unit, wherein the first ground path unit covers at least each of corners of the back plate, wherein the second ground path unit vertically overlap the first ground path unit.

Provided is an in-vehicle operation button installation structure, including: a surface material in which a button operation unit is formed on a portion; and an operation button assembly attached to a back surface of the surface material and including a button corresponding to the button operation unit.

Embodiments are disclosed for a standardized car interface for cockpit controllers in vehicles. In one example, a system for coupling a vehicle cable for communication with components of an infotainment system, comprises: a housing, a domain controller, and a first connector interface including all connections for the domain controller. In the event that a first domain controller is exchanged for a second domain controller, a collection of user preferences may be transferred between the first domain controller to the second domain controller.

Panel assemblies and button trees for panel assemblies are provided. In one embodiment, a button tree includes a frame, and a plurality of arms extending from the frame. At least one of the plurality of arms includes a plurality of branches. The button tree further includes a button connected to the frame by the plurality of arms, wherein each branch of the plurality of branches contacts the button. In another embodiment, a button tree includes a frame, and a plurality of arms extending from the frame. The button tree further includes a button defining a central axis, the button connected to the frame by the plurality of arms, the button including a face surface and an edge surface. The button tree further includes a locating feature extending on the edge surface generally co-axially with the central axis.

A motor vehicle has a control device which is arranged in a cockpit module and has a cable harness, which includes at least one data and/or power cable, for connecting the control device to an on-board electrical system of the motor vehicle. The control device has at least one connection for making electrical contact with the cable harness. An improved utilization of the available installation space in the cockpit region and a shortening of the requisite length of the cable harness is obtained by the connection of the control device being arranged on a side of the control device which faces an interior of the motor vehicle.

A vehicular display device includes: a display means; a control means for controlling the display of the display means; a non-volatile memory for storing at least an operation program for the control means or image data to be displayed on the display means; and a third connection terminal that can be connected with either a first connection terminal or a second connection terminal having different terminal arrangements. The vehicular display device, housed in an instrument panel of a vehicle, is provided with an external device that communicates with the control means by connecting the first connection terminal or the second connection terminal to the third connection terminal, wherein the control means determines whether over-writing of the non-volatile memory should be allowed in accordance with the type of the connection terminal connected to the third connection terminal.
