A vehicle control system for automated driver-assistance includes a controller that generates a control signal to alter operation of one or more actuators of a vehicle based on a heading of a target. Generating the control signal includes determining a first heading of the target based on sensor data. Further, a probability (pa) of the first heading being accurate is computed based on a number of heading flips encountered in a duration-window of a predetermined length. Further, a map-probability (pm) that the target is traveling according to data from a navigation map is computed. Further, a posterior probability (pf) of the first heading being accurate is computed based on the probability (pa) and the map-probability (pm). Generating the control signal further includes, in response to the posterior probability being less than a predetermined threshold, correcting the first heading, and generating the control signal based on the first heading.
