MPG Cruise Control Algorithm

[R.I.D.E.]

In the Insight I find that the highest mileage on the local very small hills is obtained when you allow the vehicle's speed to increase downhill, then use that speed to get as far as you can uphill with minimum throttle.

I do it using the instantaneous FE bar graph and try to stay above 75 MPG on the uphill portion and over 100 on the downhill.

When I follow that procedure my speed will vary between 60 and 40 MPH from the bottom to the top of the hill, which is about 40 feet elevation change.

Not sure if that would work in other vehicles, my CD is very low so the higher speeds don't cost me as much energy.
