SWITCHING OVER THE MODE OF A CONTROL UNIT BETWEEN A DIAGNOSTIC BUS AND AN EXTERNAL ETHERNET CONNECTION

摘要

The invention relates to the transmission of data in a vehicle. In particular, the invention relates to the transmission of large data quantities to a control unit of the vehicle. A method (300) for transmitting data from an external transmitter (250) to a control unit (221) of a vehicle is described. The control unit (221) is connected to the external transmitter (250) via an ethernet network (110) of the vehicle and via a diagnostic bus (120, 130, 140) of the vehicle. The method (300) comprises configuring (301, 302) the control unit (221) for the exchange of data via the ethernet network (110), and transmitting (303) the data from the external transmitter (250) to the control unit (221) via the ethernet network (110).
