Devices Using Electric/Magnetic Means TRIZ Cases
- Rail Carriage Speed Estimation Using Observer-Based Sensor Fusion
Observer-based fusion of wheel speed and acceleration data corrects slip, drift, and GNSS gaps for continuous rail carriage speed estimation.
- Wheel Speed Sensor Layout for Stronger Magnetic Flux Detection
Placing multiple detectors near the rotor center line captures larger magnetic flux changes for more accurate and reliable wheel speed sensing.
