Parallel Hybrid Electric Drive Train with Speed Coupling ( Summing)

[HOP SI XUAN DIEU]

I decide to make a Speed Coupling by connecting an DC electric Motor and a gas engine in a small hybrid car.


W out = W in1/k1 + W in2/k2 (1)
T out = T in1 . k1 = T in2 . k2 (2)

k1,k2: constant, depending on the structure of Planetary unit
W : revolution
T : Torque


The question I want to receive your oppinions is:
When we couple an engine and an electric motor:

1 - Only 1 point ( or 2 points ) on the graph T-w ( Torque- Speed) that we have : Tin1 . k1 = Tin2 . k2
So at other remaining points , how does the Coupling do? I mean : When we do not have : Tin1 . k1 = Tin2 . k2, what is the torque of the out axle of the Coupling T out ?
Which torque ( the stronger or the weaker; the torque of the engine or the Motor) will propell the vehicle ?


2. Can I Couple an electric Motor and an engine that their rating torque ( I mean the rating torque of electric motor and the torque at the revolution-that has the max power of engine) do not follow the above equivalence (Tin1 . k1 = Tin2 . k2 ) ?
I am waiting your oppinions.
Thank you very much.

This is way to advanced for my knowledge.
Maybe someone else can help!

Trying to figure this out. This is in the automotive part of me.
