Abstract: A head-up display system includes a laser adapted to project a holographic image, a spatial light modulator, an exit pupil replicator, a diffuser adapted to be positioned within a x-y plane at a center point of a vehicle eyellipse, the hologram projector adapted to project a dot pattern onto the diffuser, and a controller adapted to characterize an intensity distribution of the dot pattern, store the intensity distribution therein, acquire a location of a driver's eyes, map the location of the driver's eyes to the intensity distribution of the dot pattern, and implement corrective action based on the intensity distribution at the location of the driver's eyes.

Abstract: A method for low visibility driving includes receiving image data from a visible-light camera. The image data includes an image of an area in front of a vehicle. The method includes receiving sensor data from an object-detecting sensor. The object-detecting sensor is configured to detect an object in front of the vehicle. The sensor data includes information about the object in front of the vehicle. The method further includes detecting the object in front of the vehicle using the sensor data received from the object-detecting sensor and determining whether the visible-light camera is unable to detect the object in front of the vehicle that was detected by the object-detecting sensor. The method further includes commanding a display to generate a virtual image using the sensor data to identify the object in front of the vehicle.

Abstract: An augmented reality head-up display system for displaying graphics upon a windscreen of a vehicle includes one or more image-capturing devices that capture image data of an environment surrounding the vehicle, a graphic projection device for generating images upon the windscreen of the vehicle, and a controller in electronic communication with the one or more image-capturing devices and the graphic projection device. The controller executes instructions to receive object detection data indicating a current position of objects located within the environment surrounding the vehicle. The controller executes instructions to compare the current position of the objects within the environment with a visual location of the objects within the environment determined based on the image data to identify a visually occluded object located within the environment. In response to identifying the visually occluded object, the controller determines a contextual graphic that signifies the visually occluded object.

Abstract: A driving guidance system is provided for a motor vehicle having a windshield. The system includes an input device for generating an input signal associated with the movement of the motor vehicle, a road detection module for generating a road signal associated with a road geometry, and an ARHUD for generating a plurality of images upon the windshield. The system further includes a computer having a processor and a non-transitory computer readable medium storing instructions, such that the processor is programmed to receive the input signal and the road signal. The processor is further programmed to determine a predicted trajectory and a recommended trajectory of the motor vehicle along the road geometry based on the input signal and the road signal. The ARHUD is configured to generate the images upon the windshield and overlaid onto the road geometry to notify the driver of the predicted trajectory and the recommended trajectory.

Abstract: A head up display system of a vehicle includes: a communication module configured to receive a period until a traffic signal of an intersection of roads will change from a first state to a second state; a distance module configured to, based on the period and a present speed of the vehicle, determine a distance in front of the vehicle where the vehicle will be when the traffic signal transitions from the first state to the second state; a light source configured to, via a windshield of the vehicle, generate a virtual display that is visible within a passenger cabin of the vehicle; and a display control module configured to, based on the distance, control the light source to include, in the virtual display, a visual indicator of a location in a path of the vehicle where the traffic signal will transition from the first state to the second state.
