The throttle dual signals make a hard-wired solution for regen .. with the brake signal adjusting throttle signal below a certain threshold .. a bit more CHALLENGING shall we say.

The torque signal from the throttle applied to the motor can, IMHO, have a simple ramp rate applied to limit transmission-destroying step-changes of torque. I have not gotten to testing that as yet. I'm still trying to 'test' the hardware over-current ... or get over 450 amps AC through the controller. I expect that checking how fast the torque changes would be a GREAT test .. if I could figure out how to measure the output torque directly.

I'd settle for indirectly as well. The slope of the current on the DC motor maybe?

Ideas anyone?
