Automotive Braking Energy Recovery Mechanism

Apparatus and method to recover breaking energy from a vehicle incorporating a flywheel on either the differential mechanism or a wheel or both with a method to reintroduce the recovered energy back into driving the vehicle.  The recovery of the energy can be accomplished without conversion to an intermediate medium like electricity.

By having an inefficient clutch mechanism on a flywheel, continuous motion will impart some energy into rotating this flywheel.  A connection made to the braking system would cause a complete disengaging of the clutch from the flywheel upon the application of the brake.  The use of a counter hydraulic or similar system with a purge valve would cause the engaging of the flywheel to the motion system on the release of the brake for a preset period of time.  This would cause the stored energy in the flywheel to assist in re-accelerating the vehicle.  On full purge which would be programmed to be within a few seconds, the clutch would revert back to the inefficient (partial application) mode.
