摘要:
The present invention provides a system, a method and a computer usable medium including a program for providing road condition information to a mobile vehicle. This may be done by receiving a plurality of road points, determining a road profile value based on at least a portion of the road points and determining whether the road profile value exceeds a road profile threshold value. It may also be done by computing a suggested vehicle speed, when the road profile value exceeds the road profile threshold value, comparing the suggested vehicle speed to a sensed vehicle speed and sending an excessive speed alert to the vehicle based on the comparison.

This invention provides a method for providing vehicle navigation instructions to a destination from its current location. A database consisting of latitude/longitude coordinates may be searched for the locations of the destination, all street intersections within a proximity region of the destination. A vehicle's location may be determined through the use of a global positioning system or other type of system. The vehicle's distance from the destination and direction toward the destination may be determined. A proximity region surrounding the destination may be determined within which to search the map database for road segments. If at least one road segment intersects the vehicle's planned path of travel between the vehicle's current location and the destination, a maneuver alert road segment closest to the destination may be determined. If at least one maneuver alert road segment is found, maneuver instructions from the maneuver alert road segment may be provided.

A device for implementing a method of remotely routing a voice call forward to a telematic device is disclosed. The device first maintains a call state of the voice call in response to an answering of call forwarding rings by the telematic device. The device then forwards the calls to the next assigned device in response to a failure of a user of the telematic device to answer fake rings from the telematic device. Such a failure can be indicated by a monitoring of a prescribed number of back ring tones or a dropping of call within a prescribed timer window.

The present invention provides a system, a method and a computer usable medium including a program for a vehicle that has traveled off of a planned route. This may be done by providing a plurality of nodes located on road segments, generating a plurality of pre-established checkpoints at intersections and receiving a signal including a location coordinate identifying current vehicle position. It may also be done by comparing the vehicle coordinates to the coordinates of checkpoints, constructing a proximity ellipse in response to the aforementioned comparison and identifying at least one return path cycle within the ellipse with acceptable road segments that allow travel back to a planned route.

The present invention provides a system, a method and a computer usable medium including a program for generating navigation instructions for a vehicle. This may be done by determining a bearing between a destination point and a current location point of the vehicle, determining a proximity perimeter with radius (R) of a destination point and selecting a termination point within the proximity perimeter that is closest to the destination point as the vehicle path end point. It may also be done by determining a current location of a client vehicle on a route, determining a destination point longitude and latitude in a digital map database and by determining if a destination point is located in a digital map database. It may also be done by determining a destination point proximity perimeter with radius (R); if it is determined that a selected destination point is not located in a digital map database and by determining a distance between each termination point and the destination point, if more than one termination point exists within destination point proximity perimeter; It may also be done by determining the termination point within the destination point perimeter, with the shortest distance to the destination point.

The invention provides a method for routing a mobile vehicle around a traffic incident site. A traffic incident location and an intended vehicle route are provided to a route generation algorithm. A polygon based on the traffic incident location and the intended vehicle route is determined. At least one route exit point and at least one route re-entry point are determined. A plurality of intersections within the polygon is determined, and link weights between the intersections are assigned based on at least one condition factor. At least one alternative route between the route exit point and the route re-entry point is determined, based on the assigned link weights. Another aspect of the invention provides an algorithm for re-distributing traffic around a traffic incident site.
