Abstract: A motor vehicle includes a head up display projector producing a light field based upon image data such that the light field is reflected off of a windshield of the motor vehicle and is then visible to a driver of the motor vehicle as a virtual image. First means determines locations of physical objects visible to the driver through the windshield. Second means determines locations of eyes of the driver. An electronic processor receives first data indicative of the determined locations of the physical objects, and receives second data indicative of the determined locations of the eyes of the driver. The electronic processor produces the image data dependent upon the first data and the second data such that a symbol in the virtual image appears to be in a predetermined position relative to a selected one of the physical objects.

Abstract: A head up display arrangement for a motor vehicle includes a head up display projector including a lens with a polarizer. The head up display projector emits a linearly polarized light field via the lens. A windshield reflects the light field such that the reflected light field is visible to a human driver of the motor vehicle as a virtual image. The windshield includes an outer plastic layer sandwiched between a half-wave plate and an outer glass layer. An inner plastic layer is sandwiched between the half-wave plate and an inner glass layer.

Abstract: A motor vehicle includes a windshield having a plastic layer sandwiched between two glass layers. The plastic layer has a partially reflective element therein. The partially reflective element passes a first portion of light received from a first direction and reflects a remainder of the light in a second direction. A projection arrangement projects a light field onto the partially reflective element such that a reflected portion of the light field is visible to a driver of the motor vehicle as a virtual image.

Abstract: A motor vehicle includes an A-pillar disposed between a side view window and a windshield. A virtual image projection arrangement presents a virtual image that is visible by a driver of the vehicle in a direction adjacent to the A-pillar and appearing to the driver to be at least two meters away from the driver.

Abstract: A head up display calibration arrangement includes a substrate associated with a windshield. The substrate has a test pattern. A head up display module projects a test display in association with the windshield. The test display at least partially overlaps the test pattern. The test display is projected dependent upon at least one projection parameter value. A camera captures an image of the test display and the test pattern, and transmits an image signal dependent upon the captured image. An electronic processor is communicatively coupled to each of the camera and the head up display module. The processor receives the image signal and determines from the image signal a positional relationship between the test display and the test pattern within the captured image. The processor modifies the projection parameter value dependent upon the determined positional relationship between the test display and the test pattern within the captured image.

Abstract: A motor vehicle includes a head up display projector producing a light field such that the light field is reflected off of a windshield of the motor vehicle and is then visible to a driver of the motor vehicle as a virtual image. A sensor measures an effect of vibration on the motor vehicle and transmits a sensor signal dependent upon the measured effect. An actuator is coupled to the head up display projector and moves a component of the head up display projector such that a position and/or orientation of the virtual image as perceived by the driver is changed. An electronic processor is communicatively coupled to each of the head up display projector, the sensor and the actuator. The electronic processor receives the sensor signal and controls the actuator dependent upon the sensor signal such that the virtual image appears to be unaffected by the vibration.

Abstract: A head up display arrangement for a motor vehicle includes an image source emitting a light field. A first freeform mirror is positioned to provide a first reflection of the light field. A generally concave second freeform mirror is positioned to receive the first reflection and provide a second reflection of the light field. The second reflection is reflected off of a windshield of the vehicle so as to be visible to a driver of the vehicle. An arcuate section of a surface of the generally concave second freeform mirror receives the first reflection and provides the second reflection. An angle between the first freeform mirror and an imaginary line that is tangent to a midpoint of the arcuate section of the surface of the generally concave second freeform mirror is approximately between thirty degrees and sixty degrees.

A first concave mirror is positioned to provide a first reflection of the illuminated image. A second concave mirror is positioned to receive the first reflection and provide a second reflection of the illuminated image. A windshield is positioned to receive the second reflection and provide a third reflection of the illuminated image such that the third reflection is visible to a driver of the vehicle.

Abstract: A head-up display (HUD) uses reduced reflectivity projection optics to reduce the harmful effects of intense solar radiation on HUD components. In a HUD generally having a display, a mirror, and a combiner, an image is projected from the display to the combiner via the mirror. The reflectance of the mirror is reduced to prevent high thermal stress on HUD components. The light source is brighter than a conventional backlight, and thus compensates for the reduction in the reflectance of the mirror. Reduced mirror reflectance translates into a reduced thermal load on the display, lens, case, electronics, or wherever the solar radiation is directed.
