Re: GS450H MG1 and MG2 Torque Ratio and oddity in inverter protocol [SOLVED]
So that means, it would be impossible to use current firmware when planetary carrier is welded? =\ That makes things much harder for me.

Re: GS450H Discussion
Fantastic work on locking ring. How are you progressing on coupling MG1 and MG2 together. Are you planning to come up with something other than welding? Thank you! Helical gears are not so easy to measure, to create some sort of locking brackets. Also carrier case is welded, so to install brackets ...

Re: GS450H Discussion
Just a friendly reminder for those who is about to use standard GS450h HV cables as they is. They tend to wear under interference screen caps. In some period of time a short circuit might occur. 20211106_133614.jpg 20211106_133638.jpg Don't know if this issue was already exposed, so warning just in ...

Re: GS450H Discussion
SWEET! I am certain this is superior to my (alternate) plan of just filling that space with J-B Weld :D I just had an option of milling this part for free. It is less costly to cut those from 2mm stainless steel with laser and replace only metal clutch rings. Atleast now I'm absolutely certain that...

I've fabricated that locking ring for high range, I've shared here before, from solid piece of aluminum.
It fits like a glove.

Re: GS450H Discussion
It looks like if the ring gears are welded in place, MG1 would have a direct coupling to the wheels allowing MG1 to provide reverse. This somehow passed by my head at the first place :idea: Yup, seems like no need for locking ring, but you need to energize on of range solenoids. Clutch discs will o...

Re: GS450H Discussion
If I'm right, the mechanical pump is connected to the ring gear (green) of MG1. If the engine (blue) is locked and MG1 (yellow) turns, then the ring gear will turn and I would say the mechanical pump would also turn. But I think the pro's here can give the correct answer. https://bioage.typepad.com...

Re: Toyota/Lexus transaxle/transmission
A question about the P410, the cars with this transaxle have an EV-mode where the car runs without the ICE. However, the oil pump is driven by the engine shaft. How does this work? It can drive up to 50 km/h as long as there is a battery charge. Probably it has got the same type of oil pump drive a...

Re: GS450H Discussion
Test sample of the ring for permanently locking the high range was cut from PVC plastic.

You nee...

Re: Prius water pump wiring diagram
From what I've heared, those are not really reliable. People replace them with simple 12V pumps from Mercedes or VAG. I've bought two VAG pumps for my invertors and they just work.

Continuing torturing the transmission. :) I disassmbled that two-step planetary thing with hard to pronounce name, and took measurements of clutch discs of high range. I will not place a dxf drawing here yet. First I need to make sure that measurements are taken correctly. Clutch pack thickness is 3...

The VSS is the rear most connector on the left side of the transmission, see pic. It's the black sensor with the bright white connector in this photo: Yes, I've noticed it today. Unfortunately my harness missing that particular connector for some reason. I guess I'll find something to replace it. T...

Re: GS450H Discussion
All of the solenoids should be on PWM outputs, so one can program their own economiser? Or were they not put on PWM capable outputs in the VCU? Unfortunately, I don't know if solenoids need economizers or PWM signal. Anyway my intention now is to get rid of all hydraulics and only left mechanical p...

Re: GS450H Discussion
There is a VSS on the L110 with 15 teeth if that helps your plans. I'm using that signal with a converter box to run my mechanical speedometer/odometer. Do you have an idea of what RPM at which you'll cut the power to the electrical pump? I suppose you could map the PWM signal to alter speed of pum...

Re: GS450H Discussion
What about putting code into the VCU to only run the mechanical pump over a stated RPM? Or would it have to be based on oil pressure to really be effective? How you're going to determine work of mechanical pump? It either spins proportional with MG1 if carrier is welded or it stays still if input s...

Re: GS450H Discussion
I implemented cheap universal PWM signal generator HW-753 to drive electric oil pump. Tested at 1kHz and 50% duty. It works. =)
Good thing is that it can handle from 5 to 30 volts and can be adjusted on the go. Bought it at local market for 3 EURO.

Re: GS450H Discussion
The gearbox is oil cooled, and has an oil-water heat exchanger on the left side. Without the pump, cooling performance will likely suffer. An alternative would be to lock the power-split device, and allow the input shaft to rotate by MG1 - providing the direction is correct (and I don't think it wi...

Re: GS450H Discussion
It might be fine for the clutch to engage only when the shaft starts to spin, as long as you set a long enough throttle ramp-up time. What about the gearbox solenoids, are they designed to be powered without cooling by fluid flow? Just to be sure I'd deactivate them when the car is stationary if th...

Re: GS450H Discussion
Mechanical oil pump will not generate any pressure while vehicle is stationary. That's why the transmission has a secondary electric pump. Without oil pressure the clutch packs will disengage at stop lights. My gearbox equipped with electric pump. But I don't think it is designed to work constantly...

Re: GS450H Discussion
Did anyone welded planetary carrier? Asking becase for me it looks like a good idea, so mechanical oil pump will work and no need for complex and expensive electric oil pump. My only concern is about MG1 and MG2 RPM and direction of rotation.

Re: Toyota Auris and Yaris Inverter Logic board
So... Block IV arrived
And my first question: to make it work with resolver I need to remove R39 and R38? As I remember correct, Damien you said you'll make a jumper for switching between encoder/resolver?
