Hi. I have a problem with TSRS. The speed value on trip computer and on the columbus screen are different. That is to say, when the value on the trip computer can be “120” but on the columbus navigation screen can be “140” or “120” or “110”. The values are sometimes the identical.

 

I am using latest map and software. What can be the problem and how can i solve the issue?

The TSRS displays the last sign it sees?

 

The satnav is reliant on it's latest update?

 

I would rely on the signs I see.

 

 

 

Depending on the road, the TSR can be confused by speed limits for lorries.

E.g.: I know a road where speed limit for cars is 110km/h and 90km/h for lorries. But my TSR displays 90km/h though I do get 110km/h on my Columbus.

It changes and gets consistent again at the next speed limit sign.

I would call that a feature rather than a bug.

Surely if there is conflicting info it's better to use the safest/most conservative option.


BTW certainly in the UK there are different speed limits for different vehicles although I can't think of any I've seen where it's actually displayed on a sign post. Generally its a thing you need to know from the Highway Code

Sometimes value on the navigation screen do not change for a while, so sometimes it does not work well. But, value on the trip computer is more dynamic, so nearly all the time it shows true value.

 

Both the map and software are up to date.

 

Is this normal the different speed values for trip computer and columbus navigation screen?

Hi again. Because i did not want to start new topic, i continue to write here.

 

I have 2 images which i will add, again trip computer and columbus shows different values. As you will see trip computer shows "140" kms/ph and columbus shows "130" kms/ph. 

 

How are they get these inormations which are contradictory and from what they get these speed values.

 

I guess trip computer get the info from traffic sign recognition system and nothing else. But i think the columbus get the info from another sourse.

 

Is there any way to see these values always the same values? Of course these shows the same value for sometimes. And i want to learn about the system which manage the system if there is anybody who can explainç

 

These are the images when the car is on same position and speed info should be "140"; the information coming from trip computer and the speed info is wrong on the columbus.

 

The traffic sign recognition sees the actual road signs in place at the time of passing them.

 

For the Sat nav you are correct, it gets it's information from another source. The data for that source must not be "live", it will be updated as and when the information is downloaded to the system.

 

My understanding from Skoda's website is that map data is updated twice a year so there is plenty of opportunity for it to be incorrect, have you not had the experience of driving on a road that doesn't exist according to the Map yet?

 

It happens in my car, it probably happens in many others.

 

I doubt there is an easy solution.

 

So it is best to use the information seen by the recognition system and yourself as you drive to maintain the correct limit.
