Intersection assist
Functional description
Intersection assist is a new driver assist system, which is
oered for the first time in the 2019 Audi A8 in the driver
assistance package. It helps the driver to avoid collisions
with cross trac ahead of the vehicle.
Intersection assist helps the driver in situations in which
cross trac ahead of the vehicle can only be seen late due
to impaired visibility. Impaired visibility situations such as
this can occur at street intersections or when passing
narrow entrances and exits.

Intersection assist also aids the driver in complex trac
situations in which, for instance, a road user crossing ahead
of the vehicle is overlooked because the driver is concen-
trating on other trac.
Intersection assist only responds to cross trac if the
vehicle is traveling at a speed of at least 6.2 mph
(10 km/h). Cross trac can be a normal vehicle, a bus or a
truck, but also a cyclist or motorcyclist. If the cyclist or
motorcyclist is recognized by the system, the system
responds in exactly the same way as to a vehicle.
Intersection assist sensors
To implement intersection assist, the vehicle requires two
additional radar sensors, which are located behind the front
bumper. These radar sensors are identical in design to the
rear radar sensors and are installed for the first time at this
position in the A8. Both radar sensors monitor the area to
the front left and right of the vehicle.
Due to the positioning of the two radar sensors at the
extreme front left and front right of the vehicle, the system
can, in certain situations, detect cross trac even before
the driver sees it. Intersection assist utilizes this lead time
to provide the driver with feedback on critical cross trac
as early as possible so that the driver can respond to this
situation.
