How the Hybrid and CVT works

[Darnon]

Yep, exactly! Ford's design is more compact and efficient hence the switch from Toyota.

It's worth pointing out that Ford's hybrids always used the parallel motor layout, even for the first two generations they were being produced by Aisin (Toyota's powertrain subsidiary). So it wasn't like Ford moved away from the relationship to improve the design, and the first two in-house production years were actually plagued with a critical bearing flaw.

I thought the most interesting part was how MG1 and MG2 interact with the planetary gear set and the wheels.

It explains (at least my layman's understanding) why the blue EV bar grows as the vehicle takes off from a stop: the bigger MG2 can't spin until the tires are spinning and is limited until the vehicle speed increases.

Actually - if you start out with a full HVB 70% (even down at 65%) - you'll sometimes start out with a super long EV bar right from the start, compared to the normal view you are talking about.

So that's not why that other effect happens - both can spin up and max torque/amps available.
Generator Motor merely needs to spin matching RPM to the Traction Motor to cancel any engine spin.

During that super long EV bar - you can get it up to 20% Power Meter level so very briefly - hitting the 123A max, or 36 HP.

ETA: better picture.

Great explanation, thank you. You're right I forgot that bit of nuance regarding MG1 and MG2.

I've only driven this truck about 1500 miles over six weeks, but I have NEVER seen the large EV blue bar from a stop. The EV coach bar is always small at a stop and grows as I accelerate. At least as far as I've ever noticed.

Never had it once I've started driving longer - even hitting a red light at max HVB.
Only on startup initial drive.
If I don't pound the Go pedal. And I don't live on a highway, so...

Since starting out - going to treat it like any engine, even if that's not on yet - gentle initially.
Really applies once the ICE does turn on, if you don't pound it, it'll keep using EV mode for power for the 40-55 seconds it takes for the cat to warmup. Engine takes a tad longer depending on use.

Thanks for posting that! I just finished watching it and I learned a lot about how it works and how to optimize my driving.
