I am interested in a digital cruise control. I'm not sure I would dare try it on my car, without a lot of track testing. I would like a regular cruise control, but also a special hypermiling pulse acceleration button for pulse and glide engine off coasting.

When the pulse button is depressed, the motor accelerates at a TPS calculated to find sweet spot for efficiency, which changes with rpm and LOD. When released, the motor is shut down.

The pulse acceleration TPS (throttle position) is set using an algorithm with inputs from RPM and LOD and kept in the most efficient range for those values. The user should be able to input an acceleration level (slow, medium, fast) for the pulse. The appropriate TPS would be found either from a calculation or an array that holds rpm values, LOD values and the most efficient TPS for each data pair of rpm and LOD.
