Abstract
Official abstract text for this publication.
A method determines a run-curve of a motion of a vehicle as a function of at least a speed of the vehicle and a position of the vehicle in a continuous space. First, the method determines Markov decision process (MDP) with respect to a set of anchor states selected from the continuous space, such that a control moving the vehicle to a state transitions the MDP to an anchor state with a probability determined as a function of a distance between the anchor state and the state in the continuous space, and solves the MDP subject to constraints to determine an MDP policy optimizing a cost function representing a cost of the motion of the vehicle. Next, the method determines the run-curve based on the MDP policy.
First claim
Opening claim text (preview).
We claim: 1. A method for determining a run-curve of a motion of a vehicle during a trip along a route as a function of at least a velocity of the vehicle and a position of the vehicle in a continuous space of the trip, comprising steps of: determining a Markov decision process (MDP) with respect to a set of anchor states selected from the continuous space, such that a control moving the vehicle to a state transitions the MDP to an anchor state with a probability determined as a f…
