Displaying your speed on the windshield can be handy for keeping under
the speed limit, but Continental is taking things to the next level with
its Augmented Reality Head-up Display (AR-HUD) prototype. In addition
to showing your current speed, the system can overlay information on the
road specifically where it is most relevant to the driver, such as the
distance to the car in front, when to make a turn, or even upcoming
driving conditions.
The system draws data from the vehicle's camera and radar and
combines it with the vehicle's dynamics data, digital maps and GPS
positioning, which is used to create a model of the external view of the
car as seen from the driver's perspective. This allows the system to
project the augmented information onto the windscreen at the correct
visual point for the driver.
The system overlays full-color graphics on the real road view in a
130 cm (51 in) wide by 60 cm (23 in) high section of the driver's field
of vision at an optical-equivalent distance of 7.5 m (24 ft). The
Digital Micromirror Device (DMD) technology used in this system is
claimed to be the same as that used for digital cinema devices, such as
the Odin Handy Projector.
As part of this system, navigation symbols – such as turns – are
directly incorporated in the forward field of view, so that the driver
doses not have to look away to a GPS device located elsewhere in the
vehicle. Similarly, when distance controls such as Adaptive Cruise
Control (ACC) are enabled, a crescent-shaped icon displayed by the
AR-HUD denotes which vehicle in the field of view is detected by the
assistance system and the driver is kept alerted to any stray movements
from their own vehicle line by an incorporated lane-monitoring alert.
"In a world that is becoming increasingly complex, the AR-HUD
relieves the burden on the driver with a new quality of information,"
says Helmut Matschi, a member of the Executive Board at Continental. "In
the augmentation, we are connecting what the driver's eyes see with
explanatory information. The AR-HUD is an important step in the
direction of holistic human machine interfaces in cars for a more
comfortable, more economic, and safer driving experience. Drivers
receive all important information before their eyes in an easily
comprehensible way. This is a major step against driver distraction and
sensory overload, both now and in the future."
Developed from previous HUD systems that are currently incorporated
in many European cars, the new system is in an advanced stage of
development and has already been integrated into a demonstration
vehicle. However, unlike other systems that are being developed for
racing vehicles – such as Jaguar's Virtual Windscreen
– which require specific race-track telemetry to provide information on
other vehicles, the Continental AR-HUD collects its data using standard
on-board electronics systems.
Continental is planning to have a production-ready version of its
AR-HUD available in 2017 for purchase by automakers for incorporation in
their production model vehicles.
