Abstract: A system is provided for exchanging data between a vehicle and a mobile terminal. The system includes the vehicle having a vehicle computing device for executing a vehicle browser application. The system also includes a vehicle communication device which has a communication link to an application server in order to download at least one vehicle integration application to be un within the vehicle browser application. The system also includes the mobile terminal with a terminal computing device for running a user application, for example an application for controlling a vehicle function, for selecting a destination address and/or for requesting vehicle parameters. The system also includes a server which has a communication link to the terminal and the vehicle browser application and which is designed to provide indirect data communication between the user application of the mobile terminal and the vehicle integration application.

Abstract: A data bus system of a motor vehicle includes at least one first and one second control device which communicates with each another via at least one data bus. In order to be able to localize errors more easily, the system has at least one identification device which provides an identifier to each of the messages sent by the first and the second control device. The first control device receives a first message, and the identification device causes the first control device to provide the message sent therefrom with a first identifier. The second control device receives the message sent by the first control device with the first identifier, and the identification device causes the second control device to provide the message sent therefrom with a second identifier.
