Just bought a 24 plate, and there are a few niggles, but the main one for me is the speed sign recognition or lack of, to say it dire is a under statement (I'd like to say something stronger :lol: )

Our previous car was a 10 year old Qashqai , and the speed sign recognition was brilliant compared to the Honda, even when using main roads in town all it shows is '---' , I see the '---' more than a actual speed limit. surely this can't be what everyone else is experiencing? I also thought it was supposed to show road signs, not seen one so far.

TBH I know people will say you still need to know the speed, but with the way the speeds alter so much along a road, it's a bit of a back up for me.

It also only changes when you go past the sign (when it's working) so no chance to alter your speed.

Are there any settings I've missed or is this the poor electronic safety suite that I read reviews of was top notch, does seem to be top notch to me.

I haven't contacted Honda yet, I thought I'd see what other owners thought first.

See attached screenshot.

Would suggest you go back to the dealer and get your sales person to go through all features again as sometimes customers don't take on all the 'toys' when first shown.

Best of luck

HR-V e:HEV only uses the camera to detect signs, it does not use any map data. So you need to pass a sign before it will display a sign on the dash.

Also in built up areas where the limit is 30mph indicated by the road having street light, the traffic sign recognition will correctly show --- as there are no signs for it to display.

How you are describing your operation sounds normal.

I'll have a look in the manual to see if I've missed anything.

I get the car can only display a sign when it sees one, but it looks to me as though the car does a 'reset' after some time, approx 60 seconds, but I've not timed that. Surely to me it should carry on displaying the last speed limit, until a new sign comes along. I just find it depressing that a 10 year old car had a better camera and the display of the speed sign display was miles better.

We obviously think differently on what the car should display, especially as now most of my built up area in Gloucestershire is 20mph, so the built up area limit of 30 would be incorrect, which as it happens was the limit on the main road, I first complained about. Even in the 20 area it can display '---'.

I see that the updated model just announced is supposed to have better software, so perhaps we might get that update as well.

If you are driving along and you see say a 20mph sign the car should display 20. I really suggest you go back to the Honda dealer and get them to check out the camera, it's highly unlikely there's a problem BUT!!

If it see's a sign, it generally reads it correctly, sometimes it reads the wrong one, example where a road turns off and the sign is slightly pointed towards us.

But thats not what I'm complaining about, it's how often the display is '---' , because I think it looks for a sign approximately every 60 seconds, and if there isn't one there then it displays '---'. Where as I believe it should show the previous speed until the next sign is read. I reckon on average I see the '---' up to a third of my journey, which is a built up area.

As per the description in the owners manual, the displayed speed sign will disappear after a predetermined time and distance. So if it does not see another sign it will go to dashes.

Government guidance on speed limit signs is summarised here https://assets.publishing.service.gov.u ... 8-4%3A6387. It's also explained here https://www.lightningpass.com/speed-limits/ .

There are two basic default conditions: (i) single carriageway road without street lights = 60mph and (ii) roads (other than motorways/dual carriageways) with street lights = 30mph (is that now 20mph if in Wales?). If the actual speed limit differs from the basic conditions then there should be repeater signs. If either the distance between the repeater signs or it's slow traffic then the Honda software will reach the "I haven't seen a sign for a while" situation and show "- -". The recommended spacing between repeater signs is only guidance so local authorities that are short of money may tend to increase the intervals.

I look upon Honda's speed limit display as being backup to my own observations because, where there are lots of other signs then it's difficult to monitor everything. It's also necessary to watch out for the Honda system reading the wrong signs. In my experience this is most likely to happen when going round a roundabout and passing a turning to a road with a different speed limit (the vehicle should be clever enough to note the steering position and ignore these) or there's a different speed limit on a parallel and adjacent road.

Thanks for all info, I missed the statement in the manual. :shock:

From my point of view, I still say the software is faulty, especially as the repeater sign is only a guidance, so I think the software should display a sign until another one is read. I'd even accept a option whereby I could have the choice to display speed until new sign has been read.

Why have a display if for large amount of time it won't be displaying a speed limit, also now the software is supposed to warn about speeding then it can't do that either, so will this effect my insurance going forward if the Honda software can't show if you are speeding, i.e be invalidated because the car wasn't operating in 'normal limits' by not warning me I was speeding ? Luckily at the moment the software doesn't deliver a haptic feedback to the throttle or make you press to the floor to override, which is what I thought was what manufacturers were adding to some brands.

I just think its not been implemented correctly. I'd be interested in hearing if anyone with other cars have a similar problem with the speed displaying for a large amount of a journey no speed limit.

I think I will try and find an email address for Honda where I can email and ask if this might be changed in update, having only had the car for a few weeks, I don't know how many updates Honda have done in the past (If any).
