Abstract
The present invention is directed to methods and systems for controlling power-assisted pedal electric bicycles. Each system incorporates at least one control map that defines the dynamic response of a reference model representing desired bicycle velocity in response to the measured pedal torque imparted by the rider. The reference model contains parameters defining the desired properties of the bicycle, including desired mass and drag properties. In one embodiment, the system implements a "pedal centric" control method wherein measured rider-actuated pedal torque and the reference model are used to determine a desired pedal velocity. In another embodiment, the system implements a "wheel centric" control method wherein measured rider-actuated pedal torque and the reference model are used to determine the desired velocity of the wheel coupled to the drive motor. A closed loop velocity servo controls the motor to minimize the error between the desired rotational velocity and actual rotational velocity.
