A discussion of gliding and a comparison of methods: pedal control vs. neutral

[bwilson4web]

Excellent report!

With the data recorded, could you report the average speed for each method? It would be great to compare the constant-speed MPG to either P&G method.

A minor variation, I used cruise control to handle P&G from 25-43 MPG.This allowed me to use cruise control "resume" to handle the pulse in a consistent fashion. Minor variation, it was my approach.

Thanks!

Thanks, Bob.

I knew there was something I forgot! Interestingly, average speeds were virtually identical at 26.6 MPH. These include data only from when the vehicle was moving, excluding the red light stops and the force-charge segment.

One other inadvertent oversight in my reporting: ICE RPM. The target RPM for pulses was 1600. For the PC test, average pulse was 1615 RPM, median 1632. For the neutral test, the average and median both were 1632.

These were calculated on data points where RPM was >0 and pedal depression >20%, with one data point excluded from each set -- RPM was shown as 960 from where the ICE had not completely spun up at the beginning of a pulse.
