Motor Vehicle Navigation System
First Claim
1. A motor vehicle navigation system, comprising:
- an acoustic output device for outputting acoustic driving maneuver information; and
a processor operatively configured to determine a route to be traveled, determine driving maneuver information based on the route to be traveled and an actual position, compute at least one alternate route based on an assumption that the determined driving maneuver information is not followed, and determine whether or not to acoustically emit via the acoustic output device the driving maneuver information as a function of a difference between the route to be traveled and the alternate route with respect to at least one of an expected driving time, driving distance, and driving cost.

Abstract
A motor vehicle navigation system and method uses an output device for the acoustic output of driving maneuver information and a processor device which is equipped such that a route to be traveled is determined. Driving maneuver information is determined based on the route to be traveled and on an actual position. An alternate route is computed, assuming that the determined driving maneuver information is not observed. As a function of the difference between the route and the alternate route, particularly with respect to the expected driving time, driving distance and/or driving cost, the driving maneuver information is either acoustically emitted or not.

9. A method of operating a motor vehicle navigation system having an acoustic output device for acoustically outputting driving maneuver information and a processing device operatively configured to determine a route to be traveled along with driving maneuver information based on the route to be traveled and an actual position, the method comprising the acts of:
-
computing at least one alternate route to the route to be traveled based on an assumption that a determined driving maneuver information will not be followed; determining a difference between the route to be traveled and the alternate route with respect to at least one of an expected drive time, drive distance, and drive cost; and determining whether or not to acoustically emit the determined driving maneuver information as a function of the determined difference. - View Dependent Claims (10, 11, 12, 13, 14, 15)
