A hybrid hydraulic drive system for a vehicle comprises a prime mover, a transmission connecting the prime mover to drive wheels, a fluid energy storage accumulator, and a reversible hydraulic machine in fluid communication with the energy storage accumulator and drivingly coupled to the prime mover upstream of the transmission. The hybrid hydraulic drive system is arranged such that in a retarding mode the reversible hydraulic machine retards the drive wheels of the vehicle by pumping fluid into the accumulator. In a driving mode the reversible hydraulic machine supplies a supplementary power to the drive wheels of the vehicle using the pressurized fluid from the accumulator to assist propulsion of the vehicle. In a neutral mode the reversible hydraulic machine is disconnected from the prime mover to render the reversible hydraulic machine substantially inoperative to exert any significant driving or retarding influence on the drive wheels.

Automatic shifting control device for a bicycle
A bicycle features an automatically shifting transmission. The shifting is controlled by a controller. The controller has a number of ranges that comprise a subset of the available gear steps. The operator of the bicycle can select an appropriate range and the controller shifts gears within the range depending upon a preset map of bicycle speeds and gear steps. The operator can select other ranges as desired by upshifting or downshifting. The controller also has at least one cruising mode that decreases the likelihood of inadvertent shifting during operation of the bicycle at speeds within a preset range of speeds. In addition, the controller has an elapse mode that further reduces the number of available gear steps in a range during resumed operation after slowing below a preset speed or stopping.
