Abstract:
A gearing system for use in a motor assisted vehicle including at least a drive wheel rotatably connected to a frame comprising:a power input device for receiving an input force from a user; a first gear assembly coupling the power input device to the drive wheel and operatively associated with a transducer, the transducer being configured to output at least one signal indicative of the input force received by the power input device; a second gear assembly operatively associated with a motor and coupling the motor to the drive wheel; a sensor configured to output at least one signal indicative of a motion of either of the motor or the drive wheel; and a controller electrically connected to the sensor and to the transducer, the controller being configured to receive the output signal from the sensor and the output signal from the transducer, to compute a control signal based upon one of at least one programmed function, and to output the control signal to the motor.
