The Toyota HSD runs the engine at one of two pre-determined speeds (not
counting "off") Its the same basic idea he described. The reason that it
can do so is that the road speed is basically the sum of the engine
speed and motor/generator speed, so that road speed can vary without
changing the engine speed over a certain range, by changing the speed of
the M/G. When the road speed gets high enough, the engine kicks up to
its higher speed.
