Abstract
A system that has electrically or electro-pneumatically actuated aerodynamic structures. An electric or electro-pneumatic actuator is employed, which receives signals from an existing anti-lock braking system (ABS) controller to determine when actuation occurs. Other systems are also provided that feature electric or electro-pneumatic actuation, including underbody skirts and scoops, as well as inflatable tractor-trailer gap sealing devices, adjustable tractor-trailer gap sealing flaps and inflatable trailer upper streamlining devices. Electronic control units (ECUs) for aerodynamic system control interfacing with alternate sensors for calculating speed are also provided. Satellite navigation, platooning awareness and managed pressure reserve capability can be employed with the aerodynamics ECU.
