MPG Cruise Control Algorithm

[bobc455]

I was told a while ago that some motorcycles have a constant-throttle-position cruise control (instead of constant speed), and the reason was that you get your maximum MPG with constant throttle position. So what you propose is a 1/2-way compromise.

The only problem is that if you are on the highway and someone is passing you, then your speed changes and you wind up leapfrogging them a few times, it is poor road manners and can cause the other drivers annoyances.

I don't have cruise control, but when there is a lot of traffic around I will maintain a dead-constant speed. However given an open road, I'll use the speed-up/slow-down routine like your mini-algorithm.
