Propulsion Unit Arrangements TRIZ Cases
- Adaptive Vehicle Pedal Resistance for Temporary Torque Control
Real-time pedal resistance changes smooth torque transitions and curb risky maneuvers when road or navigation conditions become challenging.
- Drive Direction Change Control With Reduced Throttle Response
After a drive-reverse switch, reduced throttle response limits unintended acceleration and gives the driver time to correct direction errors.
- Steering Wheel Thumb Wheel Mounting Without Dashboard Obstruction
A steering-wheel-mounted thumb wheel controls acceleration without steering wheel machining while keeping the dashboard fully visible.
- X-By-Wire Accelerator Pedal Conical Bearings for Realistic Friction Feel
Conical bearing surfaces and a preloaded spring raise pedal friction in x-by-wire systems while preserving reliable angle detection.
- Vehicle Main Switch for Grouped Driver Assistance Control
A grouped main switch lets drivers turn lower-intervention assistance functions on or off together, cutting switch count and distraction.
- Accelerator Pedal Vibration Feedback for Precise Low-Force Control
Targeted 10-300 Hz pedal vibration improves throttle input accuracy and feel without raising reaction force or driver fatigue.
- Accelerator Pedal Module With Adjustable Reaction Force Storage
A movable inner housing lets one actuator vary pedal reaction force and compactly store accelerator components during autonomous driving.
- Steering-Wheel Hand Throttle for Constant Off-Road Engine RPM
A rotatable steering-wheel switch replaces mechanical linkages to hold constant engine RPM and reduce off-road operator fatigue.
- Single-Pedal Speed Control With Seamless Acceleration-Braking Transition
A single pedal uses reference-based input and haptic transition feedback to blend engine and brake requests for smoother vehicle speed control.
- Single-Pedal Velocity Control for Seamless Vehicle Braking
A single pedal routes driver input to engine or brake control, removing pedal-switch delays and improving deceleration response.
- Vehicle Torque Control Using Pitch Rate Estimation for Ride Comfort
Pitch rate estimation and perceptual filtering correct vehicle torque during acceleration and deceleration to reduce pitch sensation and improve ride comfort.
- Ride-on Mower Accelerator Pedal Forward Reverse Switching
Switching device redirects accelerator pedal actuation to resolve complexity trade-offs in ride-on mower forward and reverse travel control.
