Video or Simulation of Pulse & Glide - GreenHybrid

mjcmjc · #1 (**permalink**) 04-09-2007, 12:20 PM

Obviously, I hope no one has taken the video while driving, but does anyone know of a video or simulation where someone actually shows / narrates the pulse and glide technique?

I looked on YouTube, but saw nothing.

{edit} PS: Several threads reference a FAQ about best driving techniques, the only FAQ I'm finding on this forum is about posting / managing my account. Where ist he MPG FAQ?

I did one a few weeks ago > http://www.cleanmpg.com/forums/showthread.php?t=3958

In the video, I run the engine a couple of seconds, then glide down the alley to a main road after three turns (sorry the camera is shaky and makes the ride seem....rough). The video ends half-way to the 0.4 mile glide to the first stoplight - got still pictures of the rest of the way.

I generally do this early in the morning when traffic is generally not a problem

Chuck, For some reason your video reminds me of a pinball game--especially when you a going down the alley (chute).

If you watch the video, on the first turn is a house that is for rent. It's been frequented by a Ford F350 at times.

I wish it was on the video posted to give it the "monster with a chain gun" around the corner in Doom II.

I am sure your neighbors see you and think, "Here comes Smilin' Bob with his big gun. We had better get out of his way."

It would be fun to vaporize anyone that impedes our glide path.

I generally make my alley run at 6am. Peak speed is typically 22mph.

That's not really a good example of P&G. That is an example of FAS or "Forced Auto Stop".

Maybe that's all you can do in an Insight, but that's not how most people do it... most people with a hybrid capable of EV that is....

P&G usually does NOT require turning the key off!

gpsman1,

Could you refrain from bait please?

Pulse and glide and Forced Autostop existed decades before hybrids....please refrain from this silly HSD vs IMA hybrids feud and your differences as to how Wayne Gerdes hypermiles. I have not been personal with you in the past and would appreciate if you could return the favor.

That run on the video was running with the gas engine on about 20 or so yards, then coasting with the engine off as much as 0.4 miles - definitely pulse and glide. Emphasis is on the glide, but that's the point.

mjcmjc requested a video, then you proceded to attack it - that's why I hesitated to provide it. Not a very helpful atmosphere when someone attempts to provide info, only to have another member attack it.

It's a fine video. Just label it what it really is please.

John,

{trying to be dispassionate here} Perhaps you might want to define your terms - P&G, FAS, etc. If you want to describe P&G on an HSD, go for it - it would be helpful to the requestor. My definition of Pulse and Glide is not restricted to any type of vehicle, as it's been used since the 1930's or 1940's

Pro’s include maximizing FE in a low speed suburban or city environment (speed limits less then 45 miles per hour). Con’s include lowering your overall average speed (more time to get to point B), a lot of work given the undulations depending on the type of hybrid or non-hybrid you are driving, and both gear reduction starter and pre-mature transmission wear from re-engagements at speed depending on the automobile being analyzed.
