Abstract
Abstract Comfortable navigation is made possible with a small amount of transmitted information by a terminal unit, a central station and a process for the transmission of route information completely defining a route of a vehicle in a traffic network, which route is suggested as a navigation aid, from a central traffic station to a terminal unit in the vehicle. The route information concerns path points located on the suggested route, wherein a path point is defined wherever it is recommended by the central traffic station that the vehicle turn off from a road. Additional information defining the next path point following in the driving direction of the suggested route is transmitted in addition to route information at a path point.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A process for transmitting route information completely defining a route of a vehicle in a public traffic network, which route is suggested as a navigation aid, from a central traffic station to a terminal unit in the vehicle, wherein the route information concerns path points located on the suggested route, the process comprising: defining a first path point wherever instructed by the central traffic station that the vehicle turn off from a road on which the vehicle is located; and transmitting additional information defining a next path point following in a driving direction of the suggested route in addition to route information at a path point to the terminal unit, the additional information defining the next path point after the first path point by indicating turn possibilities between the two path points, the transmitting step including a turning direction required for the route at a path point.
Claim 2
Dependent Claim
147 words
A process for transmitting route information completely defining a route of a vehicle in a public traffic network, which route is suggested as a navigation aid, from a central traffic station to a terminal unit in the vehicle, wherein the route information concerns path points located on the suggested route, the process comprising: defining a first path point wherever instructed by the central traffic station that the vehicle turn off from a road on which the vehicle is located; and transmitting additional information defining a next path point following in a driving direction of the suggested route in addition to route information at a path point to the terminal unit, the additional information defining the next path point after the first path point by indicating turn possibilities between the two path points, the transmitting step including a turning direction required for the route at a path point.
Claim 3
Dependent Claim
26 words
A process according to claim 1 , wherein the additional information defines a length of road between the first path point and the next path point.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
15 words
A process according to claim 1 , wherein a number of right-turn possibilities is indicated.
Claim 6
Dependent Claim
21 words
A process according to claim 1 , including transmitting a name of the road to be taken to the terminal unit.
Claim 7
Dependent Claim
37 words
A process according to claim 1 , wherein the defining step includes defining a path point wherever a road with a determined name is exited in a digital map of the traffic network in the central station.
Claim 8
Dependent Claim
27 words
A process according to claim 1 , including transmitting the information from the central traffic station to the terminal unit in the vehicle in a wireless manner.
