Is THS-like hybrid system now common? For Japanese manufacturers, only Toyota uses THS-like system. AFAIK Germans too. I've researched past for my curiosity, but it seems that parallel-hybrid is more common for worldwide. Chrysler Pacifica also looks like THS-like. I wish manufacturers open how system work.

This article covers well (Japanese but figures are English so not block machine translation). https://anopara.net/2016/03/11/%E5%90%84%E7%A4%BE%E3%81%AE%E...

I found is also somewhat hard to get good info on these systems. It's colored by knowing they are five/six axis machines[1] where you have one or more motors controlling an axis.

A three axis machine is a triangle. Think three linkages pinned. Not very interesting. But a four axis machine is a simple gear train like you have with most battery powered cars. A five axis machine requires two inputs to define the motion of the remaining free axis. Far as I can tell that's what the original Toyota's used. Engine + Motor1 on one input. M2 on the ring gear. Drive shaft is the remaining.

Lot of different ways to skin that cat and they can look mechanically very different.

I thought Honda mostly switched to THS-like sometime mid 200x? I know their early stuff wasn't and you could get a manual transmission Honda Civic Hybrid, but I had rwad that they switched.

Looks like Hyundai/Kia aren't though. And I wasn't able to get a good read on a lot of them. I guess I over generalized from Toyota, Honda, Ford, and Chrysler.

AFAIK there's no THS-like Honda cars. Nissan and Mazda bought THS system from Toyota and sold small amount of cars only once.

I mean, this[1] sounds like THS, mostly. I don't think THS (or Ford) use any clutches though.

It's just early i-MMD (basically series-hybrid, but also can drive directly by engine on highway) system, according to PR, despite they said "eCVT". It's confusing. They called two motor(generator) connected via electricity (but not connected mechanically) as "eCVT". It uses clutch to switch direct drive on highway. https://global.honda/newsroom/news/2013/4130620eng-accord.ht...
