Power Train For A Pedal Vehicle

Patent No. EP2841328 (titled "Power Train For A Pedal Vehicle") was filed by E Drives on Apr 26, 2013. The application was issued on Dec 6, 2017.

Patent Summary

A motive power unit for a pedal vehicle comprises a control unit, a first motor, a second motor, and an epicyclic train consisting of a sun gear, a planet holder, and a ring. The ring is connected to a bottom-bracket spindle as the epicyclic train's first input. The first motor connects to the sun gear, while the second motor meshes with the bottom-bracket spindle. The planet holder connects to an output sprocket. Both motors feature sensors measuring angular velocity, connected to the control unit. A measuring element provides a torque signal for the first motor. The control unit generates a rotation speed control signal for the first motor and a torque control signal for the second motor based on measured angular speeds, set values, and the torque signal.
