Graphical projection is a protocol by which an image of a three-dimensional object is projected onto a planar surface without the aid of numerical calculation, used in technical drawing.

Sound visualization in a head-up display for a vehicle

PendingUS20260156432A1Signal processingMicrophones signal combinationSound source locationSound visualization
Methods and vehicle with sound visualization are provided. A vehicle includes a graphic projection display; exterior microphones mounted to the vehicle; and a processing device programmed to receive audio signals from the exterior microphones; retrieve map data in a region around the vehicle; identify from the audio signals a sound of interest; identify a location of a source of the sound of interest; determine a stationary status or a moving status of the source; when the source has the moving status, determining a direction and speed of movement of the source; ascertain from the map data and from the location, stationary status, moving status, direction, and / or speed, a preferred driving maneuver; determine a graphic exemplifying the preferred driving maneuver; and display the graphic upon the graphic projection display.

Head-up display for displaying graphics on a vehicle's windshield

Head-up display (10) for displaying graphics on a windshield (12) of a vehicle (14), the head-up display (10) comprising: a graphics projection module (22) for generating one or more graphic images (42) on the windshield (12) of the vehicle (14); a forward-facing camera (24) that collects image data representative of a view of the vehicle's (14's) surroundings (34) visible through the windshield (12); an ambient light sensor (28) that detects a degree of ambient light in the area (34) surrounding the vehicle (14);and one or more controllers (20) in electronic communication with the graphic projection module (22), with the forward-facing camera (24) and with the ambient light sensor (28), wherein the one or more controllers (20) are configured to execute instructions to: monitor the image data from the forward-facing camera (24) until determining, based on the image data, that an object (40) of interest is visible through the windshield (12); in response to determining that the object (40) of interest is visible through the windshield (12), determine one or more graphic images (42) to be displayed on the windshield (12) to draw a user's attention to the object (40) of interest; determine the degree of ambient light in the vicinity (34) of the vehicle (14) based on an ambient light signal received from the ambient light sensor (28);and to adjust the saturation level of one or more colors of the one or more graphic images (42) generated by the graphic projection module (22) on the basis of the ambient light present in the environment (34); wherein adjusting the saturation level of the one or more colors of the one or more graphic images (42) includes increasing the saturation level when the level of ambient light decreases and decreasing the saturation level when the level of ambient light increases.

Projection device for a vehicle and method for projecting optically perceptible elements

PendingCN122449773AProjection opticsLight guide
A projection device (1) for a motor vehicle for projecting optically perceptible patterns onto a surface, having a light source (2) suitable and for emitting a light beam and a pattern-generating element onto which at least a portion of the light beam emitted by the light source impinges, wherein the pattern-generating element has a first light-transmissive region (B1) which at least partially transmits the light beam emitted by the light source (2) and impinging onto the pattern-generating element and a second light-blocking region (B2) which blocks the light beam emitted by the light source and impinging onto the pattern-generating element. According to the invention, the second region is scattering and / or reflective for the light beam emitted from the light source and impinging onto the pattern-generating element (4), and the projection device (1) has a light guide device (6) which is suitable and / or for inputting at least a portion of the light beam reflected and / or scattered and / or transmitted by the pattern-generating element into a further light system.
