Is it ? The article mentions "Integrated Starter Generator (ISG), which saves weight by combining the functions of the starter motor and generator"
Also, in the "ECO-HYBRID" you have the both the options of the auto and manual shifting, with EV only mode in low speed.
I just don't understand why the motor and ICE are not connected directly but with two clutches, leaving the rest of the powertrain to the control of the user and having the ECU meddle with the throttle, clutches and power to the motor.
Anyway, thanks for the info !
- 392 3y agoTwo more clutches to wear and be replaced adds weight, space, maintenance, and cost. Motorcycles are an art in throwing away assemblies that aren't necessary.
- _yb2s 3y agoI'm confused now about the ISG also. I suspect it serves as a 12v alternator for lights, etc. and the main battery charging is done through the hybrid motor, but it's hard to tell from the limited info in the article. Further confusing is that the EV only mode is supposed to work up to "gear 4" which suggests perhaps the motor is before the transmission, in a manner similar to what you suggested with two clutches.
