Abstract
An automotive vehicle includes a body. A movable member with first and second positions having distinct aerodynamic profiles is disposed on an exterior portion of the body. An actuator is coupled to the movable member and configured to actuate the movable member between the first and second positions. A sensor is configured to, during a drive cycle, detect a relative road load between the second aerodynamic profile and the first aerodynamic profile. A controller is configured to, during a drive cycle, control the actuator to move the movable member to the first position in response to satisfaction of a first operating condition, to control the actuator to move the movable member to the second position in response to satisfaction of a second operating condition, and to, in response to the relative road load being positive, control the actuator to move the movable member to the first position.
