Abstract
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.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
74 words
A vehicle navigation system comprising a database of roads to be traveled by a vehicle; a system for determining a position of the vehicle relative to the database; a system for determining a route to a destination in said database of roads; an output device for indicating a maneuver instruction to a driver at an interval before an upcoming maneuver along the route; and a system for determining said interval based upon vehicle type.
Claim 2
Dependent Claim
74 words
A vehicle navigation system comprising a database of roads to be traveled by a vehicle; a system for determining a position of the vehicle relative to the database; a system for determining a route to a destination in said database of roads; an output device for indicating a maneuver instruction to a driver at an interval before an upcoming maneuver along the route; and a system for determining said interval based upon vehicle type.
Claim 3
Dependent Claim
35 words
A vehicle navigation system of claim 1 including a database of vehicle types wherein said system determines a first interval for a first vehicle type and determines a second interval for a second vehicle type.
Claim 4
Dependent Claim
29 words
A vehicle navigation system of claim 2 wherein said first interval is different than said second interval when said first vehicle type is different than said second vehicle type.
Claim 5
Dependent Claim
16 words
A vehicle navigation system of claim 2 including a system for selecting a specific vehicle type.
Claim 6
Dependent Claim
26 words
A vehicle navigation system of claim 1 including a database of vehicle types, said database associating each of a plurality of vehicle types with different intervals.
Claim 7
Dependent Claim
17 words
A vehicle navigation system of claim 1 wherein said interval is further determined based upon vehicle speed.
Claim 8
Dependent Claim
26 words
A vehicle navigation system of claim 1 wherein said interval is further determined based upon a distance from a current vehicle position to said upcoming maneuver.
Claim 9
Dependent Claim
30 words
A vehicle navigation system of claim 1 wherein said interval is further determined based upon a time for the vehicle to travel from a current position to said upcoming maneuver.
Claim 10
Independent Claim
83 words
A method for indicating a maneuver instruction to a driver at an interval before a maneuver including the steps of: (a) determining a position relative to a database of roads; (b) selecting a destination in the database; (c) determining a route to the destination in the database where the route includes a plurality of maneuvers; (d) indicating a maneuver instruction to a driver at an interval before each of the maneuvers along the route; and (e) determining the interval based upon vehicle type.
Claim 11
Independent Claim
83 words
A method for indicating a maneuver instruction to a driver at an interval before a maneuver including the steps of: (a) determining a position relative to a database of roads; (b) selecting a destination in the database; (c) determining a route to the destination in the database where the route includes a plurality of maneuvers; (d) indicating a maneuver instruction to a driver at an interval before each of the maneuvers along the route; and (e) determining the interval based upon vehicle type.
Claim 12
Dependent Claim
26 words
The method of claim 9 further including the step of (f) selecting a first vehicle type from a database of vehicle types prior to step (d).
Claim 13
Dependent Claim
32 words
The method of claim 10 further including the step of (g) determining a first interval for the first vehicle type based on data in the database of vehicle types during step (e).
Claim 14
Dependent Claim
64 words
The method of claim 11 further including the steps of (h) selecting a second vehicle type from the database of vehicle types; and (i) determining a second interval for the second vehicle type based on data in the database of vehicle types where the second interval is different from the first interval when the first vehicle type is different than the second vehicle type.
Claim 15
Dependent Claim
31 words
The method of claim 9 further including the steps of (f) measuring vehicle speed prior to step (e); and (g) further determining the interval based on vehicle speed during step (e).
Claim 16
Dependent Claim
35 words
The method of claim 9 further including the step of (f) further determining the interval based upon a distance between a current position relative to the database of roads and the maneuver during step (e).
Claim 17
Dependent Claim
74 words
A vehicle navigation system comprising: an input device for selecting a desired destination from a database of roads; a processor for determining a route from a current vehicle position to the desired destination in the database, said route including a plurality of maneuvers; and an output device for indicating a maneuver instruction to a driver at an interval before an upcoming maneuver along the route wherein said interval is determined based upon vehicle type.
Claim 18
Dependent Claim
74 words
A vehicle navigation system comprising: an input device for selecting a desired destination from a database of roads; a processor for determining a route from a current vehicle position to the desired destination in the database, said route including a plurality of maneuvers; and an output device for indicating a maneuver instruction to a driver at an interval before an upcoming maneuver along the route wherein said interval is determined based upon vehicle type.
