Free Wheeling Gear

neutral gear with variable resistance
 
(+2, -2)
  [vote for,
against]

Free-wheeling is generally dangerous because of the loss of feeling a driver experiences through ones controls. However if the relief of the road permits, free wheeling is quite a good way to cut down on fuel (i only drive manual vehicles), however because it sometimes effects road handling it isnt always practical.

i propose a mechanism that encourages a driver to free- wheel by maintaining suitable resistance in the final drive, thereby improving feel recieved by the driver.

for inexperienced free-wheelers the most common mistake is the inability to select the correct gear to return to when the engine needs to be engaged. for this i suggest that the manual gear shift be moved into the correct gear by some electro-mechanical device.

Locking Freewheel Locking_20Freewheel
Trying to solve the same problem, but lacking any details of how to implement it. [mitxela, Aug 26 2009]

Or do what most diesels do, and simply cut the fuel to the engine, whilst leaving the drive-train unbroken.

       i was thinking of a flywheel (baked) that intercepts the gearbox and the engine. when applying neutral the flywheel kicks in and by using the break pedal to slow down the wheels, this brake pedal would also control a clutch that engages the gearbox and flywheel.   

       this idea is not about conservation of kinetic energy, in order to reclaim it later, however the flywheel could double as a generator/capacitor of a sort, this is half-baked/baked.   

       this idea employs the 'engine braking' that the engine would otherwise provide, under normal circumstances.

       sp. "brake"   

       Have a display with a number that shows suggested gear that changes based on speed. Also, apply the fully baked assisted-tranny-throttle-blip system that the new 370z's use ...   

       Also, maybe post "Freewheeling encouraged" signs on suitable hills, although that could cause problems, as most roadways are plagued by idiots.

       I think that a locking freewheel would have better results, but it's easier said than done.   

       As for the hills, I think there should be legislation regarding the placement of traffic lights at the bottom of hills. It means you have to waste all your energy on the way down, and use more energy accelerating on the way up (as opposed to hitting the hill at speed).
