Detection of road signs
Detection of road signs
Introduction
The system displays speed limits on the instrument panel according to road signs detected
on the side of the road.
It mainly uses information provided by the camera 1 attached to the windscreen, behind the rear view mirror. Depending on the country,
the system also uses information from a map to interpret certain signs (town entrance,
etc.).
The sign displayed on the instrument panel changes when a road sign is detected by
the system.
Once the speed limiter or the adaptive cruise control is activated, you can adapt
the limited speed setpoint to the speed displayed on the instrument panel by the system
SPEED LIMITER and STOP AND GO ADAPTIVE CRUISE CONTROL.
If the detected speed limit is exceeded, the road sign displayed on the instrument
panel is modified to inform the driver.
Location of the camera 1
Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).
Special features
For vehicles with a map subscription:
- if the vehicle is travelling in a country where the speed units differ from those of the vehicle, the system displays the speed limit sign in the unit of the country, alongside the speed limit converted to the unit used by the vehicle’s instrument panel;
- for countries where the speed limit is reduced during rainy weather on some types of roads, the system may alter the detected speed limit after a few seconds of the windscreen wipers being activated.
Operation

- 2.
- Speed limit signs and additional speed limit signs (speed on exit ramp with arrow, speed with a caravan, speed limit with length of application, etc.)

If the detected speed limit is exceeded, a circle around the road sign flashes (warning

the detected speed limit.

intended to replace the due care and attention of the driver, who should at all times
be in control of the vehicle.
The driver should always adapt their speed to the traffic conditions, regardless of
