Abstract

A vehicle system of a vehicle includes a viewing tracking system configured to monitor a driver viewing direction of a vehicle driver and generate driver viewing direction information that indicates the driver viewing direction of the vehicle driver; and an image projection system configured to receive the driver viewing direction information and project an image into the driver viewing direction of the vehicle driver based on the driver viewing direction information. An image projection direction of the image projection system at which the image is projected varies based on a change in the driver viewing direction of the vehicle driver.

First claim

What is claimed is:

1 . A vehicle system of a vehicle, comprising:
a viewing tracking system configured to monitor a driver viewing direction of a vehicle driver and generate driver viewing direction information that indicates the driver viewing direction of the vehicle driver; and an image projection system configured to receive the driver viewing direction information and project an image into the driver viewing direction of the vehicle driver based on the driver viewing direction information, wherein an image projection direction of the image projection system at which the image is projected varies based on a change in the driver viewing direction of the vehicle driver, wherein the image projection system includes a first vehicle headlight and a second vehicle headlight that are configured to project the image onto an image display area of an environment located outside of the vehicle, wherein the image display area of the environment corresponds to the driver viewing direction of the vehicle driver, wherein the image display area of the environment varies based on the change in the driver viewing direction of the vehicle driver, wherein the image projection system is configured to determine, based on the driver viewing direction information, whether the driver viewing direction of the vehicle driver corresponds to a first angular region of the environment, a second angular region of the environment, or a third angular region of the environment, wherein the second angular region of the environment is arranged between the first angular region and the third angular region of the environment, wherein the first vehicle headlight is configured to project the image, if the driver viewing direction of the vehicle driver corresponds to the first angular region, wherein the second vehicle headlight is configured to project the image, if the driver viewing direction of the vehicle driver corresponds to the third angular region, and wherein the first vehicle headlight is configured to project a first portion of the image and the second vehicle headlight is configured to project a second portion of the image, if the driver viewing direction of the vehicle driver corresponds to the second angular region.

2 . The vehicle system of claim 1 , wherein the image projection system includes a head-up display that is configured to project a further image onto an image display area of a windshield or side window of the vehicle,
wherein the image display area of the windshield or the side window corresponds to the driver viewing direction of the vehicle driver, and wherein the image display area of the windshield or the side window varies based on the change in the driver viewing direction of the vehicle driver.

3 . The vehicle system of claim 1 , wherein the first vehicle headlight and the second vehicle headlight are matrix headlights.

4 . The vehicle system of claim 1 , further comprising:
an object detection system configured to detect an object in the environment and detect a safety hazard based on a position of the object relative to the vehicle, wherein the image is an alarm pattern in response to the safety hazard being detected.

5 . The vehicle system of claim 4 , wherein the image projection system is configured to project the image of the alarm pattern onto a road surface in front of the vehicle.

6 . The vehicle system of claim 4 , wherein the image projection system is configured to project the image of the alarm pattern onto the object.

7 . The vehicle system of claim 4 , wherein the object detection system includes at least one of a radar sensor, a lidar sensor, or a camera sensor.

8 . The vehicle system of claim 4 , further comprising:
an audio system comprising a plurality of speakers including at least one first speaker located on a driver side of the vehicle and at least one second speaker located on a passenger side of the vehicle, wherein the audio system is configured to output an alarm sound in response to the safety hazard being detected.

9 . The vehicle system of claim 8 , wherein the audio system is configured to activate the plurality of speakers in response to the safety hazard being detected.

10 . The vehicle system of claim 8 , wherein the object detection system is configured to generate position information corresponding to the position of the object relative to the vehicle,
wherein the audio system is configured to receive the position information and activate the at least one first speaker or activate the at least one second speaker based on the position information, wherein the audio system is configured to activate the at least one first speaker if the position information indicates that the position of the object corresponds to the driver side of the vehicle, and wherein the audio system is configured to activate the at least one second speaker if the position information indicates that the position of the object corresponds to the passenger side of the vehicle.

11 . The vehicle system of claim 1 , wherein the viewing tracking system includes a camera that tracks at least one of a head position of the vehicle driver or an eye position of the vehicle driver for generating the driver viewing direction information.

12 . The vehicle system of claim 1 , wherein the viewing tracking system is configured to monitor a passenger viewing direction of a vehicle passenger and generate passenger viewing direction information that indicates the passenger viewing direction of the vehicle passenger,
wherein the image projection system is configured to receive the passenger viewing direction information and project a further image into the passenger viewing direction of the vehicle passenger based on the passenger viewing direction information, wherein a passenger image projection direction of the image projection system at which the further image is projected varies based on a change in the passenger viewing direction of the vehicle passenger, and wherein the image projection system is configured to align the passenger image projection direction of the image projection system at which the further image is projected with the passenger viewing direction such that the further image is projected directly into a line-of-sight of the vehicle passenger.

13 . The vehicle system of claim 12 , wherein the image projection system includes a head-up display that is configured to project the further image onto an image display area of a windshield or side window of the vehicle,
wherein the image display area of the windshield or the side window corresponds to the passenger viewing direction of the vehicle passenger, and wherein the image display area of the windshield or the side window varies based on the change in the passenger viewing direction of the vehicle passenger.

14 . The vehicle system of claim 13 , further comprising:
an object detection system configured to detect an object located outside of the vehicle and detect a safety hazard based on a position of the object relative to the vehicle, wherein the further image is an alarm pattern in response to the safety hazard being detected.

15 . A method of displaying information during operation of a vehicle, the method comprising:
monitoring a driver viewing direction of a vehicle driver; generating driver viewing direction information that indicates the driver viewing direction of the vehicle driver; and projecting an image into the driver viewing direction of the vehicle driver based on the driver viewing direction information, wherein an image projection direction at which the image is projected varies based on
