Abstract: A rear spoiler system for a vehicle includes a fluid supply system, an elastic bladder, and a frame. The bladder receives and confines a fluid delivered thereto by the fluid supply system. The bladder dilates upon an increase in a pressure inside the bladder resulting from an increase in the amount of the fluid confined therein, and contracts upon a decrease in the pressure inside the bladder resulting from a decrease in the amount of the fluid confined therein. A surface of the bladder defines an outer, exposed, and visible surface of the vehicle. The frame is arranged inside the bladder, defines a shape of the bladder, and moves with the bladder when the bladder dilates and contracts. When dilated, the upper surface of the bladder stands proud of an adjacent outer surface of the boot so as to act as a rear spoiler for the vehicle.

Abstract: A method of producing a desired driving performance for a vehicle includes regulating a pressure inside a bladder, which defines an outer surface of the vehicle. A change in the bladder pressure changes the shape of the bladder, and thereby changes a shape of the outer surface of the vehicle, thus affecting the aerodynamics of the vehicle. The bladder pressure is regulated to be at a target bladder pressure based on the driving condition of the vehicle, which target bladder pressure can be derived from real-time machine learning or based on previous testing of a prototype of the vehicle, and thus affects aerodynamics of the vehicle so as to produce the desired driving performance for the vehicle in the driving condition.
