1. A method for controlling a pitch of a vehicle, comprising:
determining, via a control unit of the vehicle, while the vehicle is driving on a route, a slope profile comprising a mathematical function indicating a strength of a concavity or convexity and a change in a slope with respect to a position of an upcoming roadway section of the route which the vehicle is heading towards; and
predictively controlling actuators of a suspension of the vehicle, to set the pitch of the vehicle in dependence on the determined slope profile, wherein the actuators increase a distance between a front axle of the vehicle and a chassis of the vehicle in relation to a distance between a rear axle and the chassis if the slope profile indicates that the slope of the upcoming roadway section which the vehicle is heading towards is increasing and negative.
