How the Hybrid and CVT works

[Prickly Pear]

Here is a shorter video using the actual Maverick drive train.

This video uses a Toyota minivan as the example, but at minute 51 he mentions what many in this group already know. The Ford Maverick uses the Toyota Hybrid technology. Though this video is a bit long I found it very informative, particularly the explanation of the “CVT” and how the AWD works. I recommend watching it at 1.5 speed.

Nobody in this group knows that the Maverick uses Toyota technology, because they do not.

They shared patents on the early versions of the eCVT but Ford brought development in house with the HF35 and NOW Toyota uses a design that mirrors Ford’s technology.

Learned a lot watching this. Also reminded that Ford licensed the hybrid system from Toyota. Thinking out loud, will Toyota dealers work on Mavericks?

No they did not.

Are there any other manufacturers that use this type of hybrid? My wife drives a Volvo XC60 with a hybrid, but it's a totally different design.

Yes they do borrow from Toyota. Toyota's first hybrids were in 1997. The Prius and the Coaster first in Japan and then the Prius was brought to the U.S. in 2000 as the 2001 model year. Please fact check the whole history. I put it in my previous posts. They came to an agreement were Ford could use the tech. The only difference is Fords high voltage electronics. Toyota is the inventor. There never was a lawsuit between Toyota and Ford. PAICE LLC sued Toyota and Ford saying it was their invention in the 2000's and lost.

It's funny you mentioned that. For some reason recently, I have been getting emails from my local Toyota dealer about coupons to do maintenance or work on my Maverick. Both the Toyota and the Ford dealer, I made the purchase at are owned by the same people.
I haven't received anything from Frd although lve been there a lot since this purchase.
Just mentioning this because I find it hilarious, you hit home with me. I still don't understand why I get the Yota emails.

It's possible all of your delership options are actually owned by the same "people" ... AKA giant coorp.



At least they do in my town

So Toyota “stole” from PAICE, Ford “stole” from Toyota. Then Toyota & Ford teamed up to defend against & defeat PAICE?

Someone’s patent attorneys dropped the ball?

No, Toyota did develop the tech and their first Hybrids where made in Japan in 1997. The Prius was released in the USA in 2001. When Ford was developing the tech, they realized to much of it was similar to Toyota's. In order to avoid a lawsuit Toyota agreed to license the Tech to Ford in exchange for Diesel direct Injection emission tech. The hybrid Escape was released in 2004.

You kind of changed the facts in your response. They didn't team up, PAICE initiated the lawsuits years apart against Toyota and Ford. Ford and PAICE settled in 2014 and settled to a licensing agreement.
There sure are a lot of misunderstandings of facts.

They never have appointments available for their Toyota cars...

I suppose there is some truth to what sparked this... at least according Toyota's global site. According to Toyota there was a cross license of some hybrid and emissions tech in 2004! It's not entirely clear which side shared what with whom though.

Edit, I did find court documents related to this with more searching, much to do about nothing from reading it. Clearly over time the story has been twisted, and I learned the wrong things from people who had the same issue.

Ford did not license hybrid technology from Toyota. Both companies developed similar technology, and sued each other over it. After a long court battle, where both sides were found to be violating each others patents, they reached a technology sharing settlement. They shared the tech from 2008-2013, when they went different ways.

No idea why people continue to spread this nonsense.

No, Ford and Toyota did not sue each other directly over hybrid technology. Instead, both automakers were sued separately by Paice LLC, a company holding key hybrid patents, 0.5.1, 0.5.5. Both companies ultimately settled with Paice, and in 2004, Ford and Toyota actually signed a licensing agreement to collaborate on hybrid technology 0.5.3. [1, 2, 3, 4]
Key details:

• Paice vs. Toyota: Paice sued Toyota in 2004, winning a case that forced Toyota to pay royalties for infringing on its hybrid technology 0.5.4. [1]
• Paice vs. Ford: Paice later sued Ford in 2010 for patent infringement, leading to a settlement in which Ford licensed the technology, 0.5.7. [1, 2]
• Ford-Toyota Collaboration: In 2004, Ford and Toyota agreed to share patents to develop hybrid systems for light trucks and SUVs 0.5.3.

The first Toyota hybrid vehicle to use an eCVT (electronic continuously variable transmission) was the 1997 Toyota Prius, launched in Japan. This marked the debut of the original Toyota Hybrid System (later known as Hybrid Synergy Drive), which paired a gasoline engine with electric motor generators, establishing the foundation for all subsequent Toyota hybrid technology. [1, 2, 3]
Key Details Regarding the First eCVT:

• Launch Date: December 1997 in Japan, with worldwide availability following in 2000. [1, 2]
• Initial System: The first-generation system used a 1.5-liter engine paired with a planetary gear set and two electric motor-generators. [1, 2]
• Evolution: The system was officially named the Hybrid Synergy Drive (HSD) in later generations and has been refined through five generations. [1, 2]
• Distinction: Unlike traditional belt-driven CVTs, and explain on the Toyota Forum that the Toyota eCVT is a power-split device designed for high efficiency and reliability. [1, 2, 3, 4, 5]

Note: The 1997 Toyota Prius used in Japan set the stage for all future Toyota hybrid and electric cars.

See my response in the post above yours, I was miss informed.

Are there any other manufacturers that use this type of hybrid? My wife drives a Volvo XC60 with a hybrid, but it's a totally different design.

Chrysler (Pacifica), Mazda, and Subaru utilize planetary eCVTs most comparable.

 

[2024ash]

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.

Please don't cite LLMs they are neither an authority or a source, link the sources they claim say what they have produced a frequently inaccurate digest of. (Paperclip kinda looking widget)

Now funnily Toyota's system copied Fords more since the early 2010s I think, when they moved the second motor from inline (spatially) to parallel with the other motor. Mechanically they go series or parallel as before. So ppl will look at a simple diagram of Ford's unit now and go "That's identical to Toyotas!!!111" but in reality Toyota changed their design to look more like Ford's

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