Electrical Steering TRIZ Cases
- Motor Housing Water Detection via Phase Voltage
A pull-up resistor monitors phase voltage changes to detect water ingress in electric motor housings.
- Variable Band Stop Filter for MDPS Vibration Control
A variable band stop filter processes motor current signals to remove vibration components from the steering system.
- Electric Track Vehicle Control via Closed-Loop Encoder Feedback
Rotation encoders feed back motor phase data to correct hydraulic flow errors, ensuring straight trajectory at high speeds.
- Torque Steer Mitigation via Learned Pinion Torque Estimation
A learning module estimates pinion torque from transmission torque to generate motor commands that counteract directional changes during acceleration.
- Saturated Steering Detection for Guided Vehicle Hitch Alignment
A sensor-based system calculates a trajectory range to autonomously align a vehicle hitch with a trailer coupler.
- Steering Assist Device Curved Path Torque Control
A steering assist device generates torque using lateral deviation and path curvature data to guide a vehicle along a target travel line.
- Single-Tooth Winding for Synchronous Motor Torque Ripple
A synchronous motor uses a crossing-free single-tooth winding design to reduce torque ripple and cogging torque.
- Vehicle Microprocessor Abnormality Detection via Sensor Request Signals
A vehicle control device uses sensor data request signals to diagnose microprocessor health.
