Abstract

A method for synchronizing data between computer systems in a multiple vehicle system architecture ensures the correlation of data between the systems. The method utilizes nametag configuration indicators, which are a series of bit values that correspond to the presence or absence of a nametag or other data point or set in a series of internal memory locations. The method comprises the steps of monitoring for synchronization initiation events, transmitting nametag configuration indicators between vehicle systems, comparing nametag configuration indicators, and, if desired, initiating appropriate resultant actions. In a preferred embodiment, the method of the present invention is directed at synchronizing data between a voice control system and a navigation system. In this embodiment, the method according to the present invention ensures that the two systems have identical nametag configuration indicators.

5. The method according to claim 1, wherein the configuration indicator of each computer system stores data related to the presence or absence of a nametag.

6. The method according to claim 1, wherein the configuration indicator of each computer system stores data related to one of a size, a time, a date stamp, and a unique identifier of a file.

7. The method according to claim 1, further comprising the second computer system transmitting the bit values corresponding to the configuration indicator from the second computer system to the first computer system.
