Abstract

A method of route calculation in an vehicle navigation device is described, whereby a route from a starting location or a current location to a destination location is calculated, so that in the case of a deficiency in the vehicle or a deficiency impairing the driver of the vehicle, the route to an alternate destination location which has facilities for eliminating the deficiency is calculated instead of the original destination location. In addition, a method of navigation of a driver of a vehicle from a starting location to at least one destination location is also described, a trip route from the starting location or a current location to the at least one destination location being determined, and driving instructions being generated as a function of a current location so that in the case of a deficiency in the vehicle or a deficiency impairing the driver of the vehicle, the trip route to an alternate destination location which has the facilities for eliminating the deficiency is calculated.

Claims

1. A method of route calculation in a vehicle navigation device, comprising:

calculating a route from one of a starting location and a current location to a destination location;

detecting a deficiency impairing a driver of the vehicle; and

if a deficiency is detected, calculating a route to an alternate destination location in place of the original destination location.

5. The method of claim 1, further comprising:

if a deficiency in one of the vehicle and the driver of the vehicle is detected, providing at least one alternate destination location to the driver of the vehicle.

6. The method of claim 5, further comprising:

calculating the route to the selected alternate destination location instead of the destination location only after an alternate destination location has been accepted by the driver of the vehicle.

7. The method of claim 5, further comprising:

calculating the route to the provided alternate destination location in place of the original destination location unless the driver of the vehicle rejects the alternate destination location.

9. The method of claim 1, further comprising:

detecting a deficiency in the vehicle via sensors in the vehicle.

10. The method of claim 9, further comprising:

checking availability of facilities at a potential alternate destination location for eliminating the deficiency in one the vehicle and the deficiency impairing the driver of the vehicle by comparing a current time of day with stored official business hours or by remote inquiry.

2. A method of navigation of a driver of a vehicle from a starting location to at least one destination location comprising:

determining a trip route from one of the starting location and a current location to the at least one destination location;

generating driving instructions as a function of a current location;

detecting a deficiency impairing the driver of the vehicle; and

if a deficiency is detected, calculating the trip route to an alternate destination.

3. A method of route calculation in a vehicle navigation device, comprising:

calculating a route to a destination location from one of a starting location and a current location;

detecting at least one of a deficiency in the vehicle and a deficiency impairing a driver of the vehicle;

if a deficiency is detected, providing an alternate destination location to the driver of the vehicle; and

recalculating a route using the provided alternate destination location in place of the destination location unless the driver of the vehicle rejects the alternate destination location;

wherein the alternate destination location includes facilities for elimination of the deficiency in one of the vehicle and the driver of the vehicle.

4. A method of route calculation in a vehicle navigation device, comprising:

calculating a route to a destination location from one of a starting location and a current location;

detecting at least one of a deficiency in the vehicle and a deficiency impairing a driver of the vehicle;

if a deficiency is detected, providing an alternate destination location to the driver of the vehicle; and

recalculating a route using the provided alternate destination location in place of the destination location unless the driver of the vehicle rejects the alternate destination location;

wherein the alternate destination has preselectable attribute.

8. A method of navigation of a driver of a vehicle from a starting location to at least one destination location, comprising:

determining a trip route from one of the starting location and a current location to the at least one destination location;

generating driving instructions as a function of the current location;

detecting at least one of a deficiency in the vehicle or a deficiency impairing a driver of the vehicle;

if a deficiency is detected, providing an alternate destination location to the driver of the vehicle; and

calculating a route to the alternate destination location instead of the destination location unless the driver of the vehicle rejects the alternate destination location;

wherein detection of a deficiency in one of the vehicle and the driver of the vehicle is performed by the driver of the vehicle.
