Method and apparatus for controlling vehicle tractive effort

A method of controlling a vehicle having an active aerodynamic feature including a moveable front spoiler assembly disposed on a front end of the vehicle and a moveable rear spoiler assembly disposed on a rear end of the vehicle, the method comprising;

• determining a current longitudinal acceleration of the vehicle;
• determining an operator desired acceleration of the vehicle;
• sensing a current speed of the vehicle;
• defining a target aerodynamic force based upon the current speed of the vehicle, the current longitudinal acceleration of the vehicle, and the operator desired acceleration of the vehicle;
• and
• sending a first control signal to the moveable front spoiler assembly to adjust a position of the moveable front spoiler assembly and sending a second control signal to the moveable rear spoiler assembly to adjust a position of the moveable rear spoiler assembly to achieve the target aerodynamic force.
