Abstract
A method of the disclosure implements a prefix-based estimator system. The method includes: receiving a plurality of vehicle states at a plurality of time points from at least one sensor coupled to a vehicle, wherein each of the plurality of vehicle states includes at least one parameter information and a discrete state; determining a most recent vehicle state of the plurality of vehicle states has at least one parameter information missing; identifying a prefix comprising a missing data pattern that matches a sequence of discrete states of a subset of time-ordered vehicle states including the most recent vehicle state, wherein the subset of time-ordered vehicle states correspond to the prefix; calculating an estimated updated vehicle state of the vehicle using an optimized prefix-based dynamic estimator based on the prefix and the subset of time ordered vehicle states; and providing the estimated updated vehicle state to a driving control system of the vehicle.
