Method for Controlling an Electric Drive Motor of an Electrically Drivable Bicycle - A simplified explanation of the abstract
This abstract first appeared for US patent application 18546329 titled 'Method for Controlling an Electric Drive Motor of an Electrically Drivable Bicycle
The patent application describes a method for controlling an electric drive motor of an electrically drivable bicycle based on the cadence and torque of the rider.
- The method involves setting predefined target speeds and torques for the electric drive motor based on the rider's cadence and torque.
- When the rider's cadence exceeds a certain threshold, the motor operates at a lower speed and torque to assist the rider.
- If the rider exerts a torque above a predefined threshold, the motor operates at a higher speed and torque to provide additional assistance.
Potential Applications:
- Electric bicycles
- Fitness equipment
- Personal transportation devices
Problems Solved:
- Efficiently assisting riders based on their cadence and torque levels
- Enhancing the overall riding experience by providing tailored motor assistance
Benefits:
- Improved rider comfort and performance
- Enhanced energy efficiency of the electric drive system
Commercial Applications:
- Electric bike manufacturers
- Fitness equipment companies
- Personal mobility device manufacturers
Questions about the technology: 1. How does the method optimize motor assistance based on the rider's cadence and torque? 2. What are the potential implications of this technology for the electric bike industry?
Frequently Updated Research: Research on optimizing motor control algorithms for electric drive systems in bicycles.
Original Abstract Submitted
A method for controlling an electric drive motor of an electrically drivable bicycle includes determining a cadence of a rider of the bicycle, and operating the electric drive motor under specification of (i) a first predefined target speed for the electric drive motor, which is lower than the cadence of the rider, and (ii) a first predefined torque for the electric drive motor, when the determined cadence of the rider exceeds a predefined cadence threshold value. The method further includes operating the electric drive motor under specification of (i) a second predefined target speed for the electric drive motor, which is higher than the first target speed, and (ii) a second predefined torque for the drive motor, when a rider torque exerted by the rider on a drive train of the bicycle exceeds a first predefined rider torque threshold value.
