Hybrid driver scores not uploding to MyT app anymore?

The car has its own SIM as part of the emergency call system. I've deliberately left my phone at home and trip details are still logged. It also means you can see where the car has gone if you and your phone are elsewhere! 

That's most interesting, Geoff. According to the Corolla manual - the 668-page PDF you can download from the Toyota website - the SIM card in the car is part of the eCall emergency system. The manual goes into considerable detail between pages 69-85 explaining how this telematics system works including quite a bit of technical detail, diagrams and a flow chart showing how data is processed related to emergency calls. This content only talks about the emergency call system and makes no reference to the MyT app and data points and hybrid scoring. I did check this earlier when I first tried to figure out the issue discussed in this thread.

So it seems clear that the MyT app doesn't use the eCall system - if it did, surely it would be referenced somewhere in the manual. But maybe it does - your experience in getting trip details even when you've not had a phone with you in your car suggests so! One other alternative perhaps is that the MyT app has access to the location data the eCall system sends to a Toyota server, and that data is used to create the hybrid scoring, which you then see in your MyT app when you next use it Just thinking out loud with this.

Maybe the developer should know - I've emailed them to ask.

The phone is a requirement for the car to talk to Toyota as the phone connects to a network that enables the car (the MyT app) to talk to Toyota, as @AndrueC notes. And the network connection needs to be robust and reliable to provide the data Toyota needs, as the developer pointed out in the email I referenced.

I'm going to contradict you there. The car does not need a phone connection to pass tracking details to Toyota. Leave your phone at home and see.

For what it's worth that was what I wasn't suggesting. I'm suggesting that the car has its own built in way of connecting to telephone networks. The thing to realise is that they aren't 'telephone networks'. They are digital radio communication networks. And any device can use them to exchange data if it has a receiver and authorisation.

Telephony just happens to be the primary use of such networks. Ultimately it's all just packets of digital data. Some of the packets represent samples of audio data (for voice calls) others are WWW data for browsers. Some of them contain data for our vehicles. It's all just a collection of 1s and 0s. If you have a bunch of 1s and 0s you want to transmit or receive then all you need is the network provider's permission and off you go.

I don’ t think you should draw any conclusions from the eCall documentation not mentioning the MyT app. The last time I looked at the big manual it didn’t mention tracking or the MyT app anywhere else either!

This is the right answer. Like I wrote earlier, MyT tracking has nothing to do with your phone. The app is just downloading the data that the car has sent to the Toyota servers. The inbuilt eCall system has a GPS and data connection that are used for this.

Thanks for the additional info @Legge, @Geoff W, @AndrueC, @RabButler

So to be clear, the data that the My T app makes use of to produce the metrics for hybrid performance comes via the eCall system that uploads that data to a Toyota server via the eCall cellular connection. It's nothing to do with connectivity from your phone which is not used by Toyota for this purpose.

Okay, have I got it right?

One additional note - it would be great if someone can cite the source of information that explains all of the above. It must be documented somewhere.

As I was writing the above note, an email came in from the My T app developers in answer to my question I asked them on how the data gets from a car to Toyota.

It is through the Ecall system and not the internet connection provided by your phone.

From the horse's mouth. I live and learn... ☺️

This is good discussion to be documented on the forum. Not even my dealer knew that MyT services are available also for cars without a navigation system/external data connection. I got the info from the local Toyota customer service team.
