I'm seeking detailed engineering specs on the Camry Hybrid drive train.

Ever since buying my TCH, I've been very interested with the inner workings of the HSD system inside. I'm trying to develop some software that simulates the hybrid power train components (primarily the power split device). I've been doing extensive research on the web and these forums and have acquired a lot of information. Unfortunately, I cannot find a place that provides exact technical specifications and am therefore missing some pieces of information. That is why I am seeking the knowledge of other techies on this site.

Here is what I have so far. This will also give you an idea of the detail I am looking for. Items with a "?" before them are unconfirmed specs. Any extra info regarding this subject will be greatly appreciated! Feel free to ask me any questions if necessary.

I've seen that Prius site and was actually inspired to do all of this research because of that site. Unfortunately, they only have Prius specs.

 

Thanks for putting that up, I had not seen it before! Two years on PriusChat and I missed it somehow. You really do learn something new every day.

 

just a little nit picking as this is a detailed engineering request.

the reverse speed cannot be negative. You cannot have a negative speed.

not that it matters at all just being picky.

 

Good call about the speed being negative. Being a physics enthusiast, I'm surprised I missed that one. I'll fix the posting. (I am notoriously nit-picky about details as well).

 

How do we know you're not an Industrial Spy for Nissan ??

 

I hope he is a spy for nissan, consumers need more choices and business needs more competition to quicken the pace of innovation.

 

andrewbmoore - Have a look at pages AP-2, EG-3, and especially CH-3 of the "New Car Features (Functions?)" Manual posted to this site. The last of these pages gives gear ratios for the planetary gear sets, and the reduction gears that lead to the differential. These are not the same as the Prius' numbers. [By the way, I can't help wondering whether the numbers for the two planetary gear sets have been interchanged on page CH-3, after viewing the transmission diagrams themselves.]
