What's "pulse and glide"? Basically it takes advantage of the slightly quirky efficiency behaviour of piston engines. They're most efficient at higher loads, so you can "pulse" up to high speed and then drop into neutral, kill the engine and glide down again. Then repeat. Hypermilers have done it for years. https://www.economist.com/babbage/2010/ ... -and-glide
So my car can assist you with this automatically. It doesn't call it P & G, but that's what it is doing.
Said car has a ~25kW/200Nm electric motor on the crank which is also the generator and the starter motor. Its the mildest of mild hybrids. The transmission is a conventional slush box auto.
Driving across MK...give it mid level hoof out of the roundabout. Electric motor helps you out so it's doing nlots of the work. At 75mph come off the pedal and the engine switches itself off. The car glides supremely well, easily enough to still be doing 60 at the next roundabout 3/4 mile away.
The really clever bit is what it does next though. It knows there's a roundabout coming up via the navigation system. It waits until you're about 400yds away then drops back into gear, starts the engine and uses the leccy motor as generator. It engine brakes like you've dropped 3 cogs but it's still in 6th doing 1500rpm. You slow down to ~20mph to go around the roundabout, then use all that recovered leccy to blitz back up to 75 again.
Marvelous stuff! Very clever
