Speed Limit Info
Principle
Speed Limit Info shows the currently applicable
speed limit in the instrument cluster and the
Head-Up Display, as well as additional signs
where applicable, for example in wet conditions.
General
The camera in the area of the interior rear-view
mirror detects traffic signs at the edge of the
road as well as variable overhead signs.
Road signs with additional instructions, for exam‐
ple restrictions applicable in wet weather, are
taken into account and correlated with informa‐
tion in the vehicle, such as the windscreen wiper
signal. The road sign and corresponding addi‐
tional signs are then displayed in the instrument
cluster and the Head-Up Display, if applicable, or
ignored, depending on the situation. Some addi‐
tional signs are taken into account in the evalua‐
tion of the speed limit, but are not displayed in
the instrument cluster.
The system considers the information saved in
the navigation system as applicable and also dis‐
plays the speed limits present on unmarked sec‐
tions of road.
