Has any more tried this while measuring the RPM and power? From my guess, the engine will not go too high (over 3000 rpm) when the car is still slow (<10 mph) to protect the MG1 from over spinning. Just curious anyone has more info about this? Roge
If I get the equations right, the ICE can never spin over 2800 rpm when the car is stationary. And it's not MG2 that needs protecting, it's MG1: 10,000 rpm on MG1 while MG2 does not run (car is stationary) means 2,778 rpm on the ICE. Then, while accelerating, the ICE rpm will increase in a linear fashion until around 73 mph when it can do 5,200 rpm: 73.27 mph with MG1 at 10,000 rpm makes the ICE rev at 5,200 rpm. I have not tested this with a scangauge and I don't know if the Prius will let the ICE rev at more than 5,200 rpm.
It's simple algebra to find car speed, engine speed, or MG1 speed when any two of those are known. Solve the equation 0= 3.6×engine speed minus 2.6×speed of ring gear minus speed of MG1. The ring gear speed is 3.268 times the speed of the wheels.
No clue except the motor(s) will do as designed to go from 0 to MAX as fast as the software lets them do it.
