1. A method of providing vehicle predictive control, comprising:
determining a driving prediction horizon in front of a vehicle;
dividing the driving prediction horizon into a plurality of steps, at least some of the plurality of steps each corresponding to a sloped section being integrated into one step according to slopes;
applying a driving prediction model, which is based on a relationship between state variable of vehicle speed and input variables of a traction force and a braking force, for each step of the plurality of steps; and
collectively computing the driving prediction model over the prediction horizon to calculate control values for the vehicle.
