1. A method for operating a navigation system in a vehicle, in which navigation data from the navigation system are transmitted to at least one of a plurality of control apparatuses of the vehicle, the method comprising the acts of:
- transmitting the data via at least one data bus to which the control apparatuses are connected;
prioritizing the navigation data, whereinthe transmission of the navigation data via the data bus is controlled on the basis of the prioritization,wherein data relating to a current geographical position and relating to a current speed are given a higher priority than maneuver data and geographical data relating to a route.

14. A method for operating a navigation system in a vehicle, in which navigation data from the navigation system are transmitted to at least one of a plurality of control apparatuses of the vehicle, the method comprising the acts of:
-
transmitting the data via at least one data bus to which the control apparatuses are connected; prioritizing the navigation data, wherein the transmission of the navigation data via the data bus is controlled on the basis of the prioritization, a minimum throughput is reserved on the data bus for transmitting the navigation data, and the minimum throughput is used to transmit the data in a prioritization order. - View Dependent Claims (15, 16, 17, 18)

19. A control system for operating a navigation system in a vehicle, in which navigation data from the navigation system are transmitted to at least one of a plurality of control apparatuses of the vehicle, the control system comprising one or more processors and associated memory configured to execute a program to:
-
transmit the data via at least one data bus to which the control apparatuses are connected; prioritize the navigation data, wherein the transmission of the navigation data via the data bus is controlled on the basis of the prioritization, wherein maneuver data for carrying out a driving maneuver at a maneuvering location are output by the navigation system, and at least one vehicle sensor and position data provided by the navigation system are used to check, even before reaching the maneuvering location, whether the maneuver has been initiated with the vehicle, and a report is output if the maneuver has not been initiated. - View Dependent Claims (20)
