Electrical Control TRIZ Cases
- Vehicle Control Device Automatic Specification Learning
A control device detects specific signals from vehicle-mounted devices to automatically determine component specifications.
- Electronic Throttle Control Fault Recovery via Sensor Correlation
Throttle actuation module opens valve using pulse-width modulation signals to restore engine vacuum levels and prevent stalling during sensor fault states.
- Air Management Valve Modulates Intake for TRU Engine
An air management valve modulates intake airflow from compartment and atmospheric ducts to cool engine air.
- Engine Fueling Control for Cylinder Deactivation Puddle Dynamics
An engine controller tracks fuel puddle mass in intake ports using distinct time constants and gain values for active and deactivated cylinders.
- Fuel Injector Needle Timing Detection via Piezo Pressure Sensing
A piezo element in the control chamber detects pressure gradients to determine nozzle needle switching times.
