Road Transport TRIZ Cases
- Commercial Vehicle Coasting Control Using Brake State Feedback
Brake-state feedback and road-slope sensing let commercial vehicles coast for fuel savings, then return to power mode when braking force is insufficient.
- Clutch Capacity Control for Downhill Coasting and Cruise Stability
Dynamic clutch control switches between coasting and constant-speed downhill travel to cut fuel use while smoothing speed changes.
- Autonomous Vehicle Coasting Control in Multi-Vehicle Traffic
Tracks each leading vehicle separately to calculate coasting viability, improving autonomous coasting decisions in variable traffic.
- Adaptive Pulse-and-Glide Vehicle Control Under Reduced Visibility
Pulse-and-glide parameters are adjusted by visibility and following distance to cut fuel use without unsettling nearby drivers.
- Vehicle Coasting Entry Control for Distance and Speed Tracking
Predicts speed and distance through coasting entry, then decouples the drive motor to save energy without losing target tracking.
- Commercial Vehicle Coasting Control Using Braking State Feedback
Braking-state feedback enables commercial vehicles to enter coasting on suitable slopes and return to power mode when braking force is insufficient.
- Vehicle Transmission Path Switching for Hydraulic Loss Reduction
A communication valve and direct clutch switch hydraulic and mechanical paths to cut heat loss and improve vehicle transmission efficiency.
- Vehicle Powertrain Freewheeling Control for Downhill Speed Management
Topography-based mode switching extends freewheeling, preserves acceleration response, and reduces fuel use, emissions, and brake wear.
- Powertrain and Brake Coordination for Downhill Coasting Speed Control
Coordinated gear-ratio and brake control maintains downhill coasting speed while reducing brake load and limiting shift shock and vibration.
- Vehicle Powertrain Freewheeling Control for Fuel-Saving Acceleration
Topography-based switching between two freewheeling modes preserves acceleration readiness while cutting fuel use, emissions, and engine wear.
- Vehicle Coasting Control Using Predicted Distance and Speed Profiles
Predicted distance and speed profiles let a vehicle enter or exit coasting while preserving target gaps, speed control, comfort, and energy savings.
- Vehicle Driving Assistance Control for Coasting-Braking Switching
An ECU switches between coasting and deceleration assistance based on target detection and driver input to cut energy use without delaying response.
- Rear-Monitoring Cruise Control for Safe Coasting Decisions
Rear sensors let adaptive cruise control limit coasting when a following vehicle is detected, improving fuel use without disrupting traffic.
