ABSTRACT:
A navigation system is used to assist a user in proceeding from a current location to a desired destination. The navigation system includes an input device for selecting a desired destination from a database of roads. The input device can also be used to specify a vehicle type, such as a truck, car, or bus, for example. The navigation system also includes a processor for determining a route from a current vehicle position to the desired destination in the database, where the route includes a plurality of maneuvers. An output device indicates a maneuver instruction to a driver at an interval before an upcoming maneuver along the route. The interval is determined based upon vehicle type such that the maneuver instruction will be communicated to the driver sooner for a larger vehicle than for a smaller vehicle. This allows the driver to have an adequate amount of time to position the vehicle to perform the upcoming maneuver.
