Abstract

Networked vehicle communications system with front end unit, terminal which can be operated by a user and associated application. A vehicle communications system having a databus and at least one front end unit which is connected thereto and has a user-interface framework unit, having at least one terminal which can be operated by the user and is connected to the databus, and having at least one functionality which is implemented in the system and can be executed with the participation of the front end unit and of the terminal. The implemented functionality is divided into a part which communicates with the user-interface framework unit and has user-interface ends and into a functional component part which communicates with the user-interface end part on the one hand and with an application framework unit on the other. The user-interface end part is located in one front end unit, while the functional component part is also located there or in another front end unit or in a multi-purpose platform unit which is also connected to the databus.

Claims

1. A vehicle communications system comprising:

a databus and at least one front end unit connected to said databus and having a user-interface framework unit,

at least one terminal which is operated by the user and is connected to the databus,

at least one functionality which is implemented in the system and can be executed with the participation of the at least front end unit and of the terminal, wherein

the implemented functionality is divided into a first part which communicates with a user-interface framework unit and has user-interface ends and into a functional component second part which communicates with both the user-interface end part and with an application framework unit, and

wherein the user-interface end part is located in one of the at least one front end unit and the functional component part is also located in said one front end unit or in another one of said at least one front end unit connected to the databus or in a multi-purpose platform unit connected to the databus.

2. The vehicle communications system according to claim 1, wherein the functional component part is assigned a virtual terminal unit via which the functional component part for communicating with the terminal, which can be operated by the user via the databus is connected, and which contains bus-specific implementation information.

3. The vehicle communications system according to claim 1, wherein

the functional component part is located in said another one front end unit or the multi-purpose platform unit, and

the functional component part is assigned a stub component and the user-interface end part is assigned a proxy component for the communication between the functional component part and the user-interface end part.
