Thank you, Tom91. Your information helped me a lot, now I can get help from the electric amplifier

Hello everybody! I got to use the electric power steering mini Cooper p56, for conversion to the evi project. I was able to receive survey messages with the help of kanhacker arduino. But there is no further launch progress, now I need the ID of the launch byte on the can bus so that I can send it t...

I had a similar behavior with the gen2 inverter and the foc5.14 firmware, the easiest thing is to try installing the firmware of earlier versions, for example foc5.11.

In addition, you need to see a screenshot of your web settings panel, perhaps because you do not have the set pinswap 5 command for the Prius

The VCU is performing commands ,and not responding any errors ( inverter ON,Inverter halted and etc ). The 55W bulb +3 X21W bulbs are as well conected according to scheme to 12v car battery 100A. But ,there is no result, any light flashing or motor turning.The stated web link is probably out of dat...

Judging by the error in the spot values, your VCU does not have a connection with the inverter, check thoroughly the wiring of the connection exactly as here https://openinverter.org/wiki/Toyota_Prius_Gen2_Inverter_Controller . Do not forget the first inclusion of 12 volts after changes in the wirin...

To help you here, we need more information from you, screenshots of settings, photos of wiring connection board-inverter-motor

I am using the Toyota Prius GEN2 Inverter controller from Openinverter.org As I know, the Prius Gen2 V2 control board cannot rotate the motor with a resolver, only the encoder. With the Prius 20 inverter, the VCU smd board with charging function is also used. Which engine do you have connected for ...

Tell me what model of control board do you use to control the inverter?

Tell me whether it is necessary to regulate the speed at all? For people who use Lexus gs 450h automatic transmission in their projects and just want to control an electric oil pump and have its speed adjustment from 0 to maximum, I found a simple solution for using a cheap 36-48v 350W bicycle contr...

It's a pity I don't yet have the necessary knowledge to understand the firmware code and can mislead others. Better, someone competent in the field of programming could see the difference.

For example, I also successfully use high-current solid-state DC relays, 60 A for pre-charging without a radiator and 400A with a large radiator for the charging port. And I like such an inexpensive solution bought on Aliexpress. https://www.aliexpress.com/snapshot/0.html?spm=a2g39.orderdetails.orde...

The solution to the reason for the inability to adjust the correct angle of the rotor position turned out to be equally simple and difficult to accept, the reason was the firmware version 5.12-5.14 foc. I installed 5.11 foc and after a couple of minutes the desired result of sincofs was found withou...

Thanks for your reply. To be honest I now don't trust either contactor so will not be using them. This is my first build so everything is new to me so sorry for the newby questions. I'm having trouble finding information on how best to use the VW contactors. They have no econonisers and draw around...

Hi guys, I found some information on the Internet that the normal operating temperature of hybrid automatic transmissions is somewhere 90-95 degrees Celsius. It seems to me that the magnets in the stator do not really like this and will affect their magnetism characteristics, also the varnish of the...

I tried different pinswap, and one of the phase variants/sensors damaged the stm32 chip, I documented this to another topic. The correct option for my inverter turned out to be only the "set pinswap 5" command

alehandro

And so guys, the resistance and voltage on the board were checked, everything turned out to be in good order and everything pointed to a failure of the stm32. Replaced stm32, programmed, now the din_ocur Error no longer appeared.

I can't spot any obvious fault either. How much is the resolver jitter, i.e. when you plot with 1000points/1000burst len what do you see? Hello Johannes, yes, this incomprehensible synchronization behavior for me has become an obsessive goal to find a solution to the problem. The graphs seem quite ...

Hey guys, I've been experimenting a bit on the bench with a prius Gen2 and a VCU, changing the switching modes of the phase current sensors' contacts, in open circuit, and got a few trips of the circuit breaker in the high voltage line. Now when I start vcu in run mode I immediately get din_ocur err...

Since its ac voltage ? Does polarity matter Like the way it does in a vr sensor or is there a polarity. You have 4 combinations for two pairs of sin/cos windings and determining the correct connection. for example: 1-2 _3-4; 1-2 _4-3; 2-1 _3-4; 2-1 _4-3. The connection of the signal windings of the...

I will leave this incomprehensible synchronization behavior here, when I find the reason, it will save someone time starting acquaintance with FOC. Now it's not solved yet and I'm looking for a reason. I will describe the essence of the situation: You can never force the motor not to rotate when sea...

alehandro

Yes manual mode is a bit quirky there. Negative iq results in backwards rotation from standstill and needs dir=Reverse. Negative iq while the motor spins forward results in regen and needs dir=Forward. Johannes, did you mean, in manual mode, that the positive "manualiq" requires the inclu...

I would think that is what happens when you have no load on the motor. Try decreasing throtcur maybe even below 1A to verify this. Also try using idlemode=always and idlespeed=100 to see if you have speed control I continued to adjust the parameters and noticed that under load the engine accelerate...
