- Steering Wheel Heating Voltage Control for EMC and Cable Flexibility
A controllable DC-DC converter regulates steering wheel heating voltage to improve EMC, reduce cable size, and keep precise temperature control.
- Steering Wheel Common-Conductor Harness for Multi-Device Integration
A common electrical conductor links multiple steering wheel devices through one harness, cutting wiring bulk and integration complexity.
- Steering Wheel HOD Driver Ability Check for Real-Time Driving Safety
A steering wheel HOD captures driver responses in real time, allowing the vehicle to assess fitness to drive and stop unsafe operation.
- Steering Wheel Grip Sensing Under Humidity With Paired Electrodes
Paired capacitive electrodes and moving-average processing improve steering wheel grip detection when humidity or water exposure distorts sensor output.
- PVD Steering Wheel Cover Coating With Reinforced Grounding
A reinforced conductive layer grounds PVD-coated steering wheel covers, preventing charge interference and connection stress damage.
- Steering Wheel Capacitive Divider for Skeleton Ground Fault Detection
A capacitive voltage divider checks steering wheel skeleton grounding, improving hands-off detection reliability when the frame connection is faulty.
- Steering Wheel Pressure Sensing for Quick Vehicle Drive Mode Switching
Pressure sensors in steering wheel grip areas trigger a preset drive mode, cutting menu navigation time and driver distraction.
- Retractable Steering Wheel Concealment With Display-Covered Cabin Space
A movable display covers the retracted steering wheel position, freeing cabin entertainment space while preserving wheel access when needed.
