Infotainment system with head-up display for symbol projection
Embodiments are disclosed for vehicle systems. An example system for a vehicle, includes a head-up display, and a central unit connected to the head-up display, wherein the head-up display is configured to project an image onto a front windshield of the vehicle or onto a separate combiner, wherein the central unit is configured to send image data to the connected head-up display to be displayed, to ascertain a position of the user's eyes, to output a symbol within the image data, to ascertain a first virtual point and a second virtual point in a surrounding of the vehicle based on a recorded image of the surrounding and/or a current position of the vehicle, and to position the symbol such that a starting point of the symbol overlaps the first virtual point and an end point of the symbol overlaps the second virtual point in a view of the user.
1. A system for a vehicle, comprising:
a head-up display,
a central unit connected to the head-up display, the central unit including a user interface,
wherein the head-up display is configured to project an image onto a front windshield of the vehicle or onto a separate combiner,
wherein the central unit is configured to send image data to the connected head-up display to be displayed,
wherein the central unit is configured to ascertain a position of the user's eyes,
wherein the central unit is configured to output a symbol within the image data,
wherein the central unit is configured to a three dimensional space in a surrounding of the vehicle based on map data of the surrounding,
wherein the central unit is configured to recognized an object within the map data of the surrounding, the recognized object having a virtual point in the three dimensional space,
wherein the central unit is configured to align at least one point of the symbol to the virtual point of the recognized object based on a position of the virtual point of the recognized object and the position of the users eyes's, and
wherein the object comprises a limitation of a road which limits a lane a driver of the vehicle is to drive on, and wherein the central unit is configured to align a plurality of points of the symbol to a plurality of viral points of the limitation of the road so that a shape of the symbol is adapted to a course of the limitation.
2. The system according to claim 1 , wherein the symbol is a semi-transparent wall overlapping the limitation of the road.
3. The system according to claim 1 ,
having a camera recording an image of the user,
wherein the central unit is configured to recognize the user's eyes or a user's head, and
wherein the central unit is configured to ascertain the position of the user's eyes based on the recognized eyes or head within the recorded image of the user.
4. The system according to claim 1 ,
wherein the central unit is configured to track the position of the user's eyes or a user's head.
5. The system according to claim 1 ,
wherein the central unit is configured to change a shape and/or a transparency and/or a color of the symbol based on the position of the user's eyes.
6. The system according to claim 1 ,
having adjustment means for adjusting a position of the projected image within a plane of the front windshield,
wherein the central unit is configured to ascertain the position of the user's eyes based on parameters of the adjustment of the projected image.
7. The system according to claim 1 , wherein the central unit is configured to adjust a focus of the symbol in an area outside the vehicle, using geometrical optics, such that the symbol appears virtually in front of the vehicle.
