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.
