String-Stable Aerodynamic Truck Platooning at Sub-5-Meter Spacings
Transmitting instantaneous lead-vehicle engine torque, friction estimates, and brake pedal travel directly to follower vehicles to eliminate string instability.
String Stability Mathematics
Ensuring the acceleration transfer function between consecutive vehicles remains strictly below 1.0 (magnitude < 0 dB) across all perturbation frequencies.
- Fuel consumption savings up to 18% through aerodynamic drag reduction.
- Sub-5-meter vehicle spacing safely maintained at 100 km/h.
- Deterministic emergency braking synchronization across 10-truck strings.
- Automatic platoon disengagement if sidelink packet loss exceeds 2%.
