ABSTRACT:
System and method for guiding a driver of a vehicle (20) from a starting point to a destination point using an assignment of levels of urgency of navigation cues. The system comprises a navigation unit (38), a controller (22) and a user interface (42). The navigation unit (38) is capable of selecting a route between the starting point and the destination point. The navigation unit (38) is further capable of generating a plurality of navigation cues to guide the driver along the selected route. The controller (22) is connected to the navigation unit (38) and receives navigation cues. The controller (22) has an urgency calculator (40) that is capable of assigning a level of urgency to the navigation cues. The controller (22) may also have a workload manager (60) that is capable of classifying an activity state of the driver as well as updating the level of urgency of the navigation cue. The user interface (42) presents the navigation cues based on the level of urgency of the navigation cues.
