Retractable aerodynamic structures for cargo bodies and methods of controlling positioning of the same

A system comprising:

• one or more actuators operatively connected to at least one panel of an aerodynamic structure to move the aerodynamic structure from a deployed position to a retracted position or from a retracted position to a deployed position;
• one or more electronic control units that process sensor signals to analyze motion of a vehicle and control the one or more actuators based on the motion of the vehicle and control logic;
• and
• one or more mechanisms that bias the aerodynamic structure into the deployed position or the retracted position when the one or more actuators are not actuated.

A system comprising:

• one or more actuators operatively connected to at least one panel of an aerodynamic structure to control positioning of the aerodynamic structure between one of a deployed position or a retracted position;
• one or more electronic control units that process sensor signals to analyze motion of the vehicle and control the one or more actuators based on motion of the vehicle and control logic;
• and
• one or more mechanisms that bias the aerodynamic structure into the other of the deployed position or the retracted position,
• wherein the aerodynamic structure comprises at least one upper panel and at least two side panels, and
• wherein the one or more actuators are operatively connected between a door of a cargo body of the vehicle and the at least one upper panel or the at least two side panels.
