Abstract

The invention relates to navigation systems for motor vehicles, in which route planning information is output via a monitor (3). Data records containing map data are stored in a storage element (5). According to the invention, the storage element (5) stores information regarding traffic restrictions which is part of a data record of the map data, and the traffic restrictions relevant to the ascertained vehicle position can additionally be displayed on the monitor (3). Furthermore, in one specific embodiment, time restrictions for traffic restrictions are likewise stored and only the traffic restrictions which are applicable at the present time are displayed.

Claims

1. A navigation system carried on board a motor vehicle, wherein the system comprises

(a) a central processor;

(b) an input and an output unit connected to the central processor;

(c) an information storage element connected to the central processor, which storage element contains;

(i) a data record of map data;

(ii) traffic restriction information applicable to the vehicle only on roadway which is open to travel by the vehicle;

(d) a display unit connected to the central processor and displaying the traffic restricted information in numeric or alpha-numeric characters constantly during the period of restriction applicability; and

(e) a wireless mobile telephone operably connected to the storage element in the navigation system, whereby the information about traffic restrictions is retrievable from a stationary transmission station in a mobile radio network and is upgradeable.

2. The navigation system as defined in claim 1, wherein the information regarding traffic restriction is taken into account when calculating a route.

3. The navigation system as defined in claim 1, wherein the navigation system contains an audio output unit and the traffic restrictions are output audibly.
