Automatic Settings and reference consumption

Recommended Posts

I do not feel that I can turn on the automatic setting because the value for my reference consumption is so far from actual. When you change the reference consumption in the app to the actual it switches off the automatic settings which seems to defeat the entire purpose of having a live odbc connection to the vehicle.  I have an AWD ID 4 and my consumption over approximately 4000 miles has been 2.7Mi/Kwh. However ABRP want to use 4.02mi/kwh when automatic settings are turned on.  These values are not even close.  What am I missing?

Thanks.

Hi @Rob Blackburn

The VW ID platform is currently known for having a horrendous power consumption in winter due to permanent battery heating, which is changing for the better, especially with new deliveries.


ABRP assumes significantly lower consumption in the driving model of the ID4 than is the case in practice in winter, since they cannot calculate the power requirement of the battery heater.

The switch "automatic settings" switches off all live data at once. However, afterwards you can still switch on the live data for SOC, traffic and weather individually. Only the reference consumption then remains your manual value.


I hope to have understood your problem correctly and hope that the answer helps you.

ABRP will "learn" from your live data as you drive and the reference consumption will calibrate.  Suggest you connect to live data, enable automatic settings and go for a few drives.  Do some slow driving, some medium speed driving and some high speed driving to get calibrated values for a range of speeds.

Fun fact, if you click/tap the little icon next to the reference value (looks like three little bars), it will tell you how well ABRP is calibrated to your vehicle.

Hope this helps.

You also have to consider, that reference consumption is not your average consumption. It resembles your consumption when driving constantly 110km/h. So this is just a reference point to adjust the whole consumption curve a bit up or down.

Got it.

Just a remark based on my experience : currenty ABRP on my ioniq 28 report a reference consumption of 94 Wh/km

Even if i set max speed to 110km/h, i always drive under, more to 100 km/h real (105 from the car) and do a lot of eco driver pulse and glide.

The consequence is that it looks like 94 is an under estimation (yes, even with the magic of ioniq 28). my SOC at arrival is always a little bit overestimated. ABRP should notice this automatically and recalculate ref consumtion ? Or does my style of driving bugs the automatic calibration ?

Do you have to use the navigation itself to get the ‘ calibration’ going or is it enough to have the app open and OBD connected?

most of my drives I don’t need to navigate but it is always good to be prepared.

Hi,

No, that's abnormally low. I'd recommend to reset your calibrated consumption value to have it re-calibrated. You can do this in:

Settings (advanced) > Car model > [your saved car, click the cogwheel] > settings (scroll down a bit in the menu) > reset consumption

Should you still not get it right, contact support or submit a bug report via the 'support & feedback' section at the bottom of the settings menu.

If you're using the OBD connection, the app needs to be kept active for the connection to stay active. Technically there's no need for active navigation but on most phone models it will be easier to prevent the screen from locking if you're using navigation.

I would like to better understand how the "live" reference consumption is calculated. Is it an average over all of the time the car is driving and ABRP is running? Is it an average over recent driving and how far back does it go? I ask because an "average" on its own is pretty useless in climates like Canada where the winter and summer temperatures are so different!

drbrake my understanding is that the live data is gathering data when the app is in use and logs it in a database some sort that also keeps track of temperature, weather elevation and so on I noticed on my car ( ID4 GTX) if I use the trailer and use the correct car settings ( set up 2 ) the expected consumption changes when I use live data. I assume when ABPR has enough data gathered for the specific car model the calibration bars will disappear.
