Character And Pattern Recognition TRIZ Cases
- Autonomous Vehicle Road Boundary Filtering for Lateral Positioning
LOS-based road boundary filtering keeps visible boundaries across frames to improve lateral positioning accuracy in autonomous driving.
- Autonomous Vehicle Image Sensor Authentication via Cross-Sensor Validation
Cross-sensor image comparison detects compromised AV sensor outputs and triggers fault notifications before invalid data affects navigation.
- Stacked Image Sensor Inference for Lower Host Data Traffic
Local ANN inference in a stacked image sensor cuts raw pixel traffic to the host while supporting higher frame rates and lower CPU load.
- Mobile Object Speed Control Across Roadway and Sidewalk Transitions
Road-type recognition switches a mobile object between roadway and sidewalk speed states to cut frequent speed changes and reduce passenger burden.
- Vehicle Battery Swap Control Without Pre-Recorded Battery Data
Vehicle and replacement battery information are acquired at swap time, enabling accurate matching without pre-recorded battery data or leakage.
- Brake Pipe Anomaly Detection Using Pressure Differential Signatures
Pressure signatures between lead and end vehicles help detect brake pipe leaks or blockages early, enabling alerts and penalty braking.
- Vehicle Handover Scene Playback for Driver Readiness Assessment
Recent key events are replayed before autonomous-to-driver transition, helping assess reaction readiness and transfer situational context safely.
- Transverse Stabilization Control Using a Safe Setpoint Direction
A safe setpoint direction guides transverse stabilization beyond steering input alone, helping prevent unsafe vehicle motion and road departure.
- Surround View Camera Calibration Using Chart Feature Detection
Automatic chart feature detection generates surround view camera calibration parameters faster while preserving image integration accuracy.
- Drowsiness State Estimation Using Blink and Eye-State Fusion
Combining blink parameters, eye-state networks, and context data improves drowsiness estimation across user and environmental variations.
- Multi-Sensor Camera Exposure Modes for Wide Dynamic Range
Using two image sensors with fixed and variable exposure settings, this case expands scene luminance capture and improves object detection.
- Vehicle Lidar Road Profiling for Predictive Surface Estimation
3D lidar road points and vehicle motion data are combined to estimate upcoming surface height and anomalies with less delay than IMU or map-based methods.
- Vehicle Roof Sensor Cleaning for Clear See-Through Areas
Approaching dirt and insects trigger nozzle jets before impact, keeping the roof sensor see-through area clear and available.
- Driver Assistance Steering for Lane-Splitting Vehicle Avoidance
Camera-based control detects motorcycles or bicycles between lanes and shifts the host vehicle away from the nearby lane line.
- Vehicle Entertainment Interface Using Real-World Object Recognition
Real-time vehicle sensor data is fed into gameplay to align virtual scenes with surroundings and reduce motion sickness for occupants.
- Road Surface Classification for Adaptive Vehicle Behavior Planning
Sensor-based road surface classification lets vehicles predict drivability and adjust speed, path, and hazard response on snow, rain, or ice.
- In-Vehicle Emotion Detection for Adaptive Driver Response
Voice and touch analysis let the vehicle adjust response detail to driver mood, reducing distraction while preserving useful information.
- Vehicle GUI Adaptation Using Occupant and Cabin Sensor Feedback
Real-time cabin and occupant sensor data drives coordinated vehicle and mobile GUI updates to improve comfort and route efficiency.
- Active Optical Sensing with Hybrid Pulse Widths for Noise-Robust Recognition
Classifying reflected signal pulses by distance and assigning one pulse width per pulse cuts noise, preserves sensitivity, and saves point-cloud memory.
