I can think of a few ways. The most simple in principle would be to have a second "pedal" behind your gas pedal, so when it gets past a certain point, you start pressing the electric motor's throttle too.

Another method would be to tie motor throttle to manifold vacuum, so that the less vacuum you have, the more assist you get, and you get regen when vaccum is really high. Or, maybe you can tie it to throttle position sensor.

A really good system would probably take all of these factors and more into account (e.g. vehicle speed), and have some formula to derive how much assist you should get.
