Abstract
A method for transmitting data from and to a control device, in particular an engine control device for a motor vehicle that has a first communication interface and a second communication interface, the method having the following steps: connecting the first communication interface to a development tool, and connecting the second communication interface to one or more function units during the development phase of the control device, transmitting data from the control device to the development tool via the first communication interface using a first communication protocol, transmitting data from the development tool to the control device via the first communication interface using the first communication protocol, breaking the connection between the first communication interface and the development tool, connecting the first communication interface to one or more additional 20 function units, and transmitting data between the control device and the other function unit or function units via the first communication interface using a second communication protocol.

12. A control unit, comprising:
-
a first communication interface, which is optionally connectable to a development tool or to one or more functional units; a second communication interface, which is connectable to the one or more functional units; a memory for storing data; a first communication unit via which data are transmitted between the memory and the first communication interface using a first communication protocol; a second communication unit via which data are transmitted between the memory and the first communication interface using a second communication protocol; and a switching arrangement, which optionally connects the first communication interface to one of the first communication unit and the second communication unit; wherein the switching arrangement is configured to connect the first communication interface optionally to one of the first communication unit and the second communication unit, and wherein the second communication interface remains permanently connected to the second communication unit. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for providing data transmission from and to a control unit, which has a first communication interface and a second communication interface (110B), the method comprising:
-
connecting the first communication interface to a development tool, and connecting the second communication interface to one or more first functional units during the development phase of the control unit; transmitting data from the control unit via the first communication interface to the development tool using a first communication protocol; transmitting data from the development tool via the first communication interface to the control unit using the first communication protocol; transmitting data between the control unit and the one or more of the first functional units via the second communication interface using a second communication protocol; breaking the connection between the first communication interface and the development tool after the termination of the development phase; connecting the first communication interface to the one ore more of the second functional units; transmitting data between the control unit and the one or more of the second functional units via the first communication interface using one of the first communication protocol and the second communication protocol; and transmitting data between the control unit and the one or more of the first functional units via the second communication interface using the second communication protocol. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
