Problems solved by technology

However, the disadvantage when using a mobile communication connection is that its transmission capacity depends on the momentary load of the communication cell and is therefore unreliable
Therefore, it is risky to integrate this transmission technology into the manufacture and / or maintenance of motor vehicles

Embodiment Construction

[0030] The drawing shows a motor vehicle 10 in a device 12 . Motor vehicle 10 may in particular be a motor vehicle, for example a passenger car. Plant 12 can be, for example, a production plant in which motor vehicle 10 is produced, or a workshop in which motor vehicle 10 is to be maintained and / or repaired.

[0031] The motor vehicle 10 can have a mobile communication module 14 , which can be, for example, a GSM module, a UMTS module or an LTE module or a module combining these radio technologies. In the motor vehicle 10 it can be provided that digital device data are exchanged between the mobile communication module 14 and one or more control units 18 , 20 via a communication bus 16 , for example a CAN bus. The mobile communication module 14 may have an eUICC 22 as a SIM card for one or more access profiles to a public mobile communication network, eg providing mobile telephony and / or Internet access. A configuration device 24 may be provided in the mobile communication mo...

Abstract

In a method for wireless exchange of device data between a control unit of a motor vehicle and a vehicle-external computing device, a mobile radio connection is established between a mobile radio module of the motor vehicle and a mobile radio cell of a radio station coupled with the computing device. The device data are transmitted via the mobile radio connection. The radio station provides a private mobile radio cell which is different from all mobile radio cells of public mobile radio networks able to reach the motor vehicle. To establish the mobile radio connection in the motor vehicle, the mobile radio module is reconfigured for registering with the private mobile radio cell by using a SIM card.

Description

technical field [0001] The invention relates to a method for the wireless exchange of device data between a control device of a motor vehicle and a fixed computing device outside the vehicle, the wireless exchange of device data being carried out in such a way that a mobile communication module and a mobile communication module of the motor vehicle and A mobile communication connection is established between base stations of the mobile communication cell coupled to the computing device and device data is transmitted via the mobile communication connection. This method is also obtained according to DE 10 2010 009 257 A1. Background technique [0002] The possibility of being able to flexibly configure systems in a motor vehicle together with the ever-decreasing cost of semiconductor memories has led to a change in the development tasks for motor vehicle production in the following way: initially different control device variants were developed for different use cases, so mode...
