I did this test today and have attached a plot. This was 0 to around 50mph on a fairly flat road with full throttle (once I'd begun moving). Contrary to what I said before, it would continue to accelerate, I just ran out of road. It just accelerates very slowly after the initial nice strong acceleration, any kind of incline limits the top speed massively.
I have also attached the current parameters I'm using. One thing I don't really understand is the throtcur parameter. I found last time that when I increased this to the maximum value of 10 it helped a lot. However, in theory I guess this means that at 100% of throttle it should be demanding 1000A. I'm obviously not getting anywhere near this so what is limiting the current? Is this all back EMF/field weakening related? Just seems that I should be supplying more current (at least during the first section of the plot) with 100% throttle acceleration.
I'm still having some overcurrent errors (even with the fault signal line from the Prius disconnected) when under load at low speeds or when releasing the throttle too quickly. It is also still jerky and very difficult to control at very low speeds. It's almost impossible to start from a standstill on a hill.
Any suggestions or advice much appreciated!
