Techniques pertaining to user notification via interior lighting for improved human-machine interface in vehicles are described. A method may involve a notification system of a vehicle receiving one or more signals each indicating a respective level of a plurality of levels of required user involvement required in operation of the vehicle. The method may also involve the notification system providing a visual notification with at least one aspect of the visual notification corresponding to the respective level of required user involvement indicated by each signal of the one or more signals.

A vehicular display device includes a facing member having a hole formed therein, an edge-light light guide that guides lights emitted from LEDs, a diffusion member that diffuses light leaking from the edge-light light guide, and a convex light guide having a main part interposed between the diffusion member and the facing member, and a projecting portion projecting into the hole. The lights emitted from the LEDs are guided to the edge-light light guide. The lights guided to the edge-light light guide are diffused by the diffusion member to enter the convex light guide, and leaves from the projecting portion.

The assembly further includes a rear bar housing having a front segment and a rear segment, the front segment of the rear bar housing coupled to the rear segment of the front bar housing. A top surface of the peripheral bar assembly is coupled to a bottom of a chassis of a display system having a display module. The assembly configured to provide accent lighting through the slot of the front bar housing.

A steering wheel includes an indicator. The indicator includes a light source that emits light and a light guide. The light guide includes an outer surface and an end opposing the light source. The light emitted from the light source enters the end of the light guide, and some of the light is emitted from the outer surface.

A vehicle instrument panel having a three-dimensional illumination effect includes a transparent ring having a three-dimensional circular shape, at least one primary scale formed in a front surface of the transparent ring, the at least one primary scale being spaced apart from an adjacent primary scale by a predetermined distance, a reflecting plate for changing a direction of travel of LED light along the transparent ring, generated below the transparent ring, in clockwise and counterclockwise directions, and a prism unit including at least one prism for reflecting a portion of the LED light traveling along the transparent ring toward the at least one primary scale at a predetermined angle.

An assembly includes a light guide having a proximal end and a distal end. The proximal end has a light-emitting diode package coupled thereto. The assembly may include another light guide, also having a proximal end and a distal end, with a light-emitting diode package coupled to the proximal end. A light housing may be included that defines a cavity therein, wherein at least a portion of the first and second light guides including the distal ends are disposed in the cavity. Further, a dial face may be included that is disposed adjacent to the first and second light guides and the light housing, wherein each of the first and second light guides are configured to illuminate the dial face. In some variations, flexible printed circuit boards are attached to and electrically connected with the light-emitting diode packages.

A lighting unit for a display apparatus for use in a motor vehicle is disclosed herein. The lighting unit includes a light transmitting panel configured to transmit light rays through to a viewing side of a display apparatus; and at least one light source operable to emit light rays across a breadth of the light transmitting panel. the light transmitting panel further comprises a reflector foil sheet applied to at least two sides of the light transmitting panel with no air gaps therebetween. A vehicle display for mounting within an interior of a motor vehicle comprising such a lighting unit, and a method of optimizing light rays for illuminating a display apparatus for use in a motor vehicle is also disclosed.

A means of transport and a device (10) for outputting a request for a driver of a means of transport to take over vehicle guidance are proposed. The device (10) comprising: a line-shaped first LED strip (1) with a first electrical connector (5) comprising a first plurality of LEDs (3), a line-shaped second LED strip (2) with a second electrical connector (6) comprising a second plurality of LEDs (4), a control device (7) comprising an interface (8) configured to receive the first electrical connector (5) and the second electrical connector (6), wherein the first plurality of LEDs (3) is arranged interleaved with respect to the second plurality of LEDs (4) and the control device is configured to output the request as light signals by controlling the first electrical connector (5) and the second electrical connector (6).

A head-up display apparatus includes light emission units, a first reflection unit, a second reflection unit, a first diffusion unit, a second diffusion unit, and a driver unit. The light emission units are disposed along one end surface of an upper or lower end surface of a combiner, and emit light. The first reflection unit is disposed to a part of the light emission units, and reflects the light. The second reflection unit is disposed to a part of the light emission units, and reflects the light. The first diffusion unit is disposed in the first side end surface, and diffuses the light. The second diffusion unit is disposed in the second side end surface, and diffuses the light. The driver unit selectively drives one of the light emission unit, and causes to emit the light. The combiner includes an invisible region.

A motor vehicle includes a distance sensor display for registering the distance of the motor vehicle from the surroundings of the motor vehicle, particularly when parking. The distance sensor display includes an optical display device with one or more light-emitting element and a control unit configured to optically display the distance registered by the distance sensor inside the motor vehicle fundamentally in the form of a notional line.
