Cruise Control MPG Sensitive Logic

Here I am at the University of Puerto Rico in Aguadilla, on there Electronics Department Laboratories, performing a test.

This is a Ford Aerostar MAP sensor, this sensor is powered with a 7805 IC, 5 volt DC fixed regulator. This sensor is supposed to create a 90-160 Hz square wave pattern when different levels of vacuum are applied to it. So, I connected a mighty vac hand pump and measured the output signal with and oscilloscope.

I wanted to know how the increments in vacuum changed the output frequency so I could graph it and probably apply it to the MPG sensitive cruise control. It turned out that it is possible to modify a cruise control so it maintains a constant fuel consumption instead of a constant speed. This is called driving with load on the hypermiler community.

If you want to read more about the experiment, go directly to the Ecomedder forum:
