PASSIVE INFRA-RED GUIDANCE SYSTEM
A passive infra-red guidance system and method for augmenting operation of an autonomous vehicle on a roadway includes at least one forward-looking infra-red imaging sensor mounted on the vehicle in operative communication with an image processor tied into the vehicle's operational system. The system determines the left and right edges of the roadway using thermal imaging, and then determines the centerline of the travel lane in which the vehicle is travelling based on the determined left and right edges of the roadway. The system then compares the determined centerline of the travel lane with the actual position of the vehicle and identifies any adjustment needed for the vehicle's position based on the comparison. The left and right edge determination may comprise identifying a difference between a thermal signature representative of the roadway and a thermal signature representative of a non-roadway portion that is located proximate to the roadway portion.

PASSIVE INFRA-RED PEDESTRIAN DETECTION AND AVOIDANCE SYSTEM
A passive infra-red pedestrian detection and avoidance system and method for augmenting the operation of a vehicle on a roadway, especially for identifying potential pedestrian/vehicular collision danger for the vehicle in operation and adjusting the position and operation of the vehicle accordingly, includes at least one passive infra-red sensor array mounted on the vehicle in operative communication with an image processor tied into the operational system of the vehicle. The system detects, using thermal imaging and processing, the presence of people that may be in or laterally crossing into the travel lane of the vehicle. The image processor analyzes the detection of a human thermal signature and determines if the detected human thermal signature is moving, in what direction and at what speed, to assess any potential threat to the pedestrian or biker, and further whether any responsive action needs to be triggered in the vehicle's operation to avoid a collision.
Power Management for a Vehicle Smart Mirror System
In one embodiment, a vehicle mirror includes an on-board diagnostics (OBD) transceiver and one or more processors. The processors access OBD data received by the OBD transceiver from an OBD port of a vehicle. The processors further determine, from the OBD data, a vehicle type, a change in voltage of the vehicle's battery, and a secondary vehicle factor. When the vehicle is determined to be a combustion engine vehicle, the processors transition the vehicle mirror from a sleep power state to an awake power state when the change in voltage is greater than a predetermined amount and the secondary factor of the vehicle is greater than a predetermined threshold. When the vehicle is determined to be an electric vehicle, the processors transition the vehicle mirror from the sleep power state to the awake power state when any activity is detected in the OBD data and the secondary factor of the vehicle is greater than the predetermined threshold.
Display device
A display device includes a light source, an optical system, a liquid crystal panel, and a first heat sink. The optical system converts light emitted from the light source into irradiation light that is to be an irradiation area having a predetermined width. The liquid crystal panel receives the irradiation light. The first heat sink includes an opening through which the irradiation light passes, and supports the liquid crystal panel. The first heat sink is in contact with the liquid crystal panel.
Backlight unit and head-up display device
A backlight unit includes a light source; a condensing unit that condenses light emitted from the light source; and a diverging unit that diverges the light entering from the condensing unit and that emits the light toward an image display unit of a light transmission type in a head-up display device. For example, the diverging unit is a lens in which both surfaces of an incident surface into which the light from the condensing unit enters as well as an emission surface from which the light is emitted toward the image display unit, are concave surfaces.
VEHICLE DISPLAY APPARATUS
A vehicle display apparatus includes an HUD that projects a display image formed at a first conjugate position to a projection member so as to place the display image as a virtual image at a second conjugate position. The first conjugate position is conjugate to a viewing region inside a vehicle through the projection member, and the second conjugate position is conjugate with an external sensor through the projection member. An HCU increases display luminance of a selected image selected from the display image to a fail-safe luminance by controlling a virtual image display state of the display image when a fail condition is met. The fail condition is that the current brightness detected by the external sensor exceeds an upper limit of an allowable range.
DISPLAY APPARATUS FOR VEHICLE
A display apparatus for vehicle is disclosed. The display apparatus includes a first display and a second display located in a vehicle, a signal processing device including a processor configured to perform signal processing for the first display and the second display, and a second signal processing device including a second processor configured to perform signal processing for a third display, wherein the processor in the signal processing device is configured to execute first to third virtual machines on a hypervisor in the processor, and, in response to the signal processing device being operated as a master signal processing device, the first virtual machine in the processor is configured to share at least some of data with the second signal processing device for divided processing of data. Consequently, the plurality of signal processing devices for the plurality of displays in the vehicle may divide and process data.
DISPLAY SYSTEM FOR A VEHICLE
A display system for a vehicle to display vehicle information includes a meter panel, a heads-up display system, and a controller. The meter panel has at least one display section and the heads-up display system includes a projector mounted on the meter panel and arranged at a front of the meter panel opposite to the at least one display section. The projector is configured to project a light to display the vehicle information on the front windshield. The heads-up display system also includes a curve mirror arranged spaced apart from the projector and is adapted to reflect and focus the light on the front windshield to display the vehicle information on the front windshield. The controller is configured to control the meter panel and heads-up display system to display the vehicle information on the meter panel and the front windshield.
Information provision device, information provision method, and recording medium storing information provision program for a vehicle display
An information provision device, information provision method, and a non-transitory recording medium storing a program for causing a computer to execute the information provision method. Each of the information provision device and the information provision method includes projecting an image light to a light transmission member to display a for-driver information image indicating for-driver information to be provided to a driver of a mobile object in a prescribed display area, and displaying at a first point where a normal for-driver information image is displayed a priority for-driver information image in place of the normal for-driver information image, where the displaying includes displaying the normal for-driver information image at a second point different from the first point for at least some of a period during which the priority for-driver information image is displayed at the first point.
