Notification function
In the following situations, the RSA system alerts the driver.
When the vehicle speed exceeds the speed notification threshold applied to
●
the speed limit of the sign displayed on the multi-information display, the sign
color becomes inverted.
If it is detected that your vehicle is overtaking when a no overtaking sign is dis-
●
played on the multi-information display, the sign flashes.
Depending on the situation, traffic environment (traffic direction, speed unit) may
be detected incorrectly and a notification function may not operate properly.
Automatic turn-off of RSA sign display
■
One or more signs automatically turn off in the following situations.
A new sign is not recognized for a certain distance.
●
The road changes due to a left or right turn, etc.
●
Conditions in which the function may not operate or detect correctly
■
In the following situations, RSA does not operate normally and may not recognize signs,
display the incorrect sign, etc. However, this does not indicate a malfunction.
The camera sensor is misaligned due to a strong impact being applied to the sensor,
●
etc.
Dirt, snow, stickers, etc. are on the windshield near the camera sensor.
●
In inclement weather such as heavy rain, fog, snow or sand storms
●
Light from an oncoming vehicle, the sun, etc. enters the camera sensor.
●
The sign is dirty, faded, tilted or bent, and if an electronic sign, the contrast is poor.
●
All or part of the sign is hidden by the leaves of a tree, a pole, etc.
●
The sign is only visible to the camera sensor for a short amount of time.
●
The driving scene (turning, lane change, etc.) is judged incorrectly.
●
Even if it is a sign not appropriate for the currently traveled lane, such a sign exists
●
directly after a freeway branches, or in an adjacent lane just before merging.
Stickers are attached to the rear of the preceding vehicle.
●
A sign resembling a system compatible sign is recognized.
●
The vehicle is driven in a country with a different direction of traffic.
●
Side road speed signs may be detected and displayed (if positioned in sight of the cam-
●
era sensor) while the vehicle is traveling on the main road.
Roundabout exit road speed signs may be detected and displayed (if positioned in sight
●
of the camera sensor) while traveling on a roundabout.
The speed information displayed on the meter and that displayed on the navigation sys-
●
tem may be different due to the navigation system using map data.
