About this project

Ebike Speed Controller System

Objective: To design and implement a speed controller system for an electric bicycle (ebike).

Context: With the rise of affordable electric mobility in India, precise speed control and safety are essential for efficient ebike operation and user experience. Custom controllers can improve performance and adaptability for local conditions.

What you'll build: You will program motor control logic in Embedded C, generate PWM signals for a BLDC or DC motor, and interface with a microcontroller such as Arduino or STM32. The project includes integrating Hall sensors for speed feedback, developing a user interface, and embedding safety features before final prototype testing.

Deliverables: A functional ebike speed controller prototype, source code, and a test report documenting performance and safety checks.

Milestones

No submission required for this milestone.

2. Motor selection and control logic design

10 marks 6d

Select a suitable motor for the ebike, specifying model, voltage, and power rating. Design and document the control logic, including a block diagram and a written explanation of how the controller manages speed and direction. Submit your motor choice rationale and annotated control logic diagram; ensure clarity and technical accuracy.

3. Speed sensing and display integration

10 marks 6d

Integrate a speed sensor with your controller and connect it to a digital display. Submit a wiring diagram and code snippet showing how real-time speed data is captured and displayed. Demonstrate the system accurately reflects wheel speed, with annotated screenshots or photos of the working display.

4. User interface development

10 marks 6d

Develop a user interface that allows the rider to set and monitor speed. Submit interface mockups or screenshots and a brief description of controls and feedback provided to the user. Ensure the interface is intuitive and all key functions (e.g., speed adjustment, current speed display) are accessible and clearly labeled.

5. Safety features implementation

10 marks 6d

Implement at least two safety features, such as over-speed protection or emergency cut-off. Submit a description of each feature, supporting circuit diagrams or code, and explain how each function is triggered and tested. Demonstrate that safety mechanisms activate as intended under relevant conditions.

6. Final testing on prototype

10 marks 6d

Test the complete speed controller system on a physical or simulated ebike prototype. Submit a test report with photos or video evidence, documenting test procedures, results, and any issues found. Confirm that all subsystems (motor control, speed sensing, UI, safety features) work together reliably under real-world conditions.
