Default Re: Pulse and Glide Questions

When I first found this board I found a link to an article on pulse and glide. It was written with the Prius in mind. It specifically stated gliding was the state where there were no arrows.

You didn't want the arrow from the wheels to the battery because the drag of the motor would slow you down quicker. Aside from which if you start pulse and glide with a high SOC then you don't need the regen.

You didn't want the arrows from the battery to the wheels because although you can go for a while using EV mode this would discharge the batteries and eventually cause the ICE to run to recharge them.

The idea behind pulse and glide is that there is no (or minimal) energy transfer between wheels and battery. The ICE only runs for about 4 seconds to increase your speed from 30 to 42 and then you glide for a while with the ICE off. If you can go 1/3 mile (just a guess) on glide you're only using about 12 seconds worth of gasoline to power the engine for each mile.

WVGasGuy, I appreciate your answers. I also have not been able to get all the arrows to stay off for more than a few seconds at a time. Because of this I have to look at the display so much that I don't think it's very safe. Since the ICE is off regardless of whether or not there is electrical power transfer you can't use your ears to tell whether your gliding. I was just posting this question because I couldn't get the car to do a long sustanined glide and was wondering if anyone else had.
