| 摘要 |
The invention relates to a method for operating a navigation system (NSYS) for a motor vehicle (KFZ) in a road network (VN), and to a navigation system. To this end, first a zone (UZ) of the road network (VN) is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle (KFZ) is associated with at least one emissions class (1, 2, 3). First, information about the geographical location of the zone (UZ) and about the emissions class (1, 2, 3) at least required there is stored in the navigation system (NSYS). Then, information about the at least one emissions class (1, 2, 3) of the motor vehicle (KFZ) is entered into the navigation system (NSYS). Thereafter, the information entered is considered in the destination guidance process, wherein destination guidance into or through the zone (UZ) is avoided if the at least one emissions class (1, 2, 3) of the motor vehicle (KFZ) is affected by emissions class-dependent drive-through restrictions in the zone (UZ).
