Abstract
A method for reducing off-tracking by a multi-trailer heavy duty vehicle during a maneuver is disclosed. The method obtains a model of vehicle dynamics describing dynamics of the multi -trailer heavy duty vehicle, determines respective force trajectories for two or more axles of the vehicle as a solution to a NOCP. The NOCP is formulated with an objective to at least minimize trailer off-tracking, and based on the model of vehicle dynamics. The motion of the heavy duty vehicle is controlled during the maneuver based on the determined force trajectories.
