E-CVT and HYBRID/ENGINE FACTS

[jsus]

But think of all the internet points you could get if you hunted down every last Maverick Hybrid on a dealer lot and managed to find the elusive non-CHEP unit...

i have seen the stickers on the trucks in person at long lewis ford on three diff occations

Did you happen to pop the hood on any of the Mavericks you saw?

I feel like you are yelling at us.

In 2004 (ish) Ford independently designed their eCVT but it was very similar to Toyota's. By mutual agreements Ford got to keep making the eCVT and they gave Toyota permission to use some of Ford's intellectual property. (Maybe it was traction control technology but don't quote me on that, it was a long time ago).

Interestingly, Toyota is now using a version of the Maverick transmission in the newest Prius (I read).

Hopefully, they are using the version that doesn't have the DAMPER issue!

Facts, eh?

I thought the engine was made in Chihuahua and the eCVT was done somewhere in Michigan. I don't care if that's right or wrong.
I'd just like Ford to build me my Maverick Hybrid!
Back to the original post, I've watched the videos that explain how the eCVT works, how planetary gears work, how the battery gets charged, and so forth.
What I still don't understand is, what physical device controls the input-vs-output of the planetary.
And if Ford would just build my truck, I'd even be OK with not understanding how all of it works!

Only the names and facts have been changed to protect the innocent, and the guilty.

Well, it's right...

What I still don't understand is, what physical device controls the input-vs-output of the planetary.

It's more simple than people expect.

Your transmission has three "gears" all permanently connected:

Gas Engine
Generator Motor
Traction Motor

At any given moment,
All are stopped
Or
All are spinning
Or
Two out of three are spinning

If wheels are moving, Traction motor must be spinning. They are tied together.

If gas engine is off (EV mode) the traction motor and generator motor spin in opposite directions.

If gas engine is on, and wheels are not turning, the generator must be turning.

The traction motor and generator motor can both provide torque in a positive or negative direction.

In general, the generator motor controls the engine RPM by providing positive or negative torque.

The wheels control the Traction motor RPM in a fixed ratio. That ratio is 125 rpm per mph with stock size tires.

As you know if you "floor it" engine RPM can ramp up really fast, but the wheels accelerated rather slowly. So with a fast ramp in engine rpm that also means a fast ramp up in generator rpm.

Think of a differential on your axle.
If one tire has resistance, and the other does not, only the one without resistance will spin.

The eCVT is like this. The generator can add resistance or reduce resistance to one device, which changes the speed of the opposite device.

P.S. this kind of "3-way" power split would not work without the aid of sensors and fast computers.

Engine sticker has already been discussed with pictures in this thread.

I think my brain will corrode after reading through this post. So much mis information.

Oh I forgot we now a term for this type of information that came out about 4-5 years ago. "Alternate Facts" Yep that must be the facts the OP is referring to.

And that other thread has already been brought up in this one, e.g. post #21.

And @baldboy already posted similar false statements over there that were debunked there.

And there it is. Those are the words of a troll. As are the attitude and lack of attempt at spelling.

You are using "facks" against facts... That must be a fancy way of saying "alternative facts"...



And as noted in the thread linked below, the one you also posted in, that is erroneous. The engines are still being built at CHEP in MX, despite the stickers indicating US origin.

Why you will neither read the thread you posted in that explains the confusion and disputes your claims. Why you make claims and expect the people you're trying to convince to prove them for you.

The smaller of the two motor/generators controls the "gear ratio" of the eCVT
This motor/generator also starts the ICE

My experience with CVTs were mixed.
Our 14 C-Max with the 2.0 was a running Bugga. Years before I had a Suzuki Kasashi with a 175 hp 2.0 and a cvt. Sexy looking car that ran like a sick dog. Couldn’t get rid of it fast enough!
C-Max is still going strong with 112,000+ miles, we passed it on to our son to use for his commuter vehicle.
