How big is the initial display?
There is a range of sizes that can be used for Image Generation. Our TFT HUDs use displays from 1.3" to 1.6" in size.
What is the magnification of the convex mirror?
There is no convex mirror in our system.
Can someone from outside see what is being projected on the windshield?
No, not as a projected image. If someone looked through the windshield and down at the dashboard, they may be able to see the display image, but it would be very small.
The head-up display reduces driver distraction and increases driver safety.
To read an instrument cluster, for at least a brief moment you have to take your eyes off the road. Your eyes need to adjust to the shorter distance (known as accommodation) before the information flow can begin.
This process takes time and tires the eyes if it happens frequently. Reading a display, including accommodation of the eye occurring twice, requires at least half a second with a conventional instrument cluster.
This means that when drivers avert their gaze at a speed of 120 km/h they will be driving blind for about 33 meters.
Drivers get all the important information such as speed, warning signals and indicator arrows for navigation without looking down to the instrument cluster or the secondary display.
In the case of a windscreen head-up display drivers see a virtual image, but not as a flat, static picture on the windshield, but rather, as “floating” over the hood at a distance of about two meters. In the case of an augmented-reality head-up display the information of the windshield-HUD is enriched with a layer of information right on the street in front of the car.
For Continental the HUD represents a key technology for its holistic approach for the human-machine-interface which will lead to a dialogue without word between the driver and his vehicle.
Always in control, always informed
Our head-up displays also make driving more comfortable. You will feel better protected, because you have all the information directly in their line of sight and therefore can recognize and catch critical situations even faster.
With improved feedback regarding the driving situation and the status of your car, it will become harder to miss important information. Speed limits for example, can be displayed in the HUD and you will be warned if you drive above the speed limit.
Information from the adaptive cruise control assures you that you are driving the correct distance from the car in front of you and gives you an early warning if you are not.
Our lane departure warning system gives immediate feedback if you are going to leave the lane. The usability of navigation systems also improves with a better visual feedback regarding the road ahead, especially with our augmented reality head-up display, where navigation information is seamlessly integrated in to the environment in front of your car.
Continental head-up displays can be easily adjusted to the needs and preferences of drivers.
This allows to customize the positioning of the virtual image on the windshield, according to the own preferences. It is also possible to adjust the contrast and the brightness.
Last but not least, you can configure what information is displayed on the HUD by turning off single information like speed limit or navigation.
How does heads-up-display (HUD) work? on Driving the Nation
Continental is working on a HUD that is separate from the windshield, about six inches wide that would sit in front of the windshield. Continental's Thorsten Alexander Kern explains how a Heads-up-display (HUD) works, technically. A HUD allows a person to see all the important information in a screen, while keeping their eyes on the road. It's a safety issue. But how does it work?
