Sounds like a complicated system with all the switching of power source. Is that done via mechanical clutches or hydraulic transmission?
“Sounds like a complicated system with all the switching of power source. Is that done via mechanical clutches or hydraulic transmission?”
like all hybrids, switching the motor/generator from one mode to the other is done electronically ... the basic motor/generator regenerative braking system has been in use on all modern rapid-transit subway-type urban trains for decades ...
Honda’s only addition is a single gear that switches the ICE engine directly from the motor/generator to direct connection with the drive axle and that’s done automatically as well
but hybrids are indeed complicated because they have all the components of an ICE engine and all of the components of an EV ...
if you’re really interested in getting down into the weeds regarding how Honda’s hybrid works, though, the following is a fantastic video:
