BMW 7 Series: Introduction
The very name "Head-Up" describes the principle benefit of this system. The Head-up Display (HUD) projects a virtual image into the driver's field of vision. Important information such as cruise control details or graphical directions from the navigation system are projected onto the windshield and are thus permanently visible within the driver's field of view.
The driver of a BMW thus has the important data and graphics put up in his field of view, just like a pilot in his jet fighter.
The head-up display in the new BMW 7 Series incorporates various functions aimed at enhancing road safety and driver convenience.
That includes display of:
- Information from the DCC cruise control system
- Information from the navigation system
- Check Control messages
- Road speed
Having the displays in the driver's direct field of view increases safety, as the eyes are always on the traffic.
