that reduces aerodynamic drag. The wind deflector on top of a truck's cab also plays a vital role in streaming air up and over the vehicle. For this reason, Jost proposes an adjustable draft deflector that pivots, like the fifth wheel itself, on a horizontal axis. The device is raised or lowered according to the speed of the vehicle, as well as the position of the trailer, through various sensors.
It's not just about reducing wind resistance either, because in the patent file Jost says the system is meant to be as automated as possible with as little driver involvement as possible.
