Abstract
A vehicle has first and second portions, with a front aerodynamic element located in the first portion and a rear aerodynamic element located in the second portion. The front and rear aerodynamic elements are each independently movable to respective deployment positions between respective stowed positions and respective fully-extended positions. A controller is operatively connected to each of the front and rear aerodynamic elements and has a processor and tangible, non-transitory memory. The controller is programmed to obtain a front target position (T) for the front aerodynamic element at a current time step (n) based at least partially on at least one vehicle state parameter at a previous time-step (n−1) and a detected position (D) of the rear aerodynamic element at the previous time-step (n−1).
