Abstract

A method for accelerated data transmission among electronic control units (ECUs) and/or measuring devices in the context of motor vehicles is provided. In order to enable an accelerated data transmission, in particular fast (low) event cycle times, a low jitter and a high data throughput, the architecture of the data transmission is split up into (i) a control plane implemented in software operating on configuration, calibration and/or diagnostics data (“CD” data), and (ii) a data plane implemented in hardware transporting measurement data (“M” data) and/or prototyping data (“RP” data).

Claims

1. A method for data transmission among at least two of electronic control units and measuring devices associated with at least one motor vehicle, comprising:

providing data transmission using a data transmission architecture which is split into a control plane and a data plane, wherein the control plane is implemented in software operating on CD data defined as including at least one of configuration data, calibration data and diagnostics data, and wherein the data plane is implemented in hardware transporting at least one of M data defined as including measurement data and RP data defined as including prototyping data.

2. The method according to claim 1, wherein the CD data are transported using transactions.

3. The method according to claim 2, wherein at least one of the M data and the RP data are transported in stateless data streams.

4. The method according to claim 3, wherein the data plane switches at least one of (i) commands and responses of transactions and (ii) data streams to and from at least one of the electronic control units and the measuring devices.

5. The method according to claim 4, wherein the method is executed within a distributed measurement, calibration and diagnostics system.

6. The method according to claim 4, wherein the method is for at least one of monitoring and controlling operation of electronic control units within the at least one motor vehicle.

7. The method according to claim 4, wherein the method is for at least one of monitoring and controlling data transmission among electronic control units within the at least one motor vehicle.

8. An interface module, wherein the interface module is configured to control data transmission among at least two of a host electronic control unit, other electronic control units, and measuring devices associated with at least one motor vehicle, the interface module comprising:

means for providing data transmission using a data transmission architecture which is split into a control plane and a data plane, wherein the control plane is implemented in software operating on CD data defined as including at least one of configuration data, calibration data and diagnostics data, and wherein the data plane is implemented in hardware transporting at least one of M data defined as including measurement data and RP data defined as including prototyping data.

9. The interface module according to claim 8, wherein the interface module is part of a measuring device for at least one of monitoring and controlling operation of an electronic control unit of a motor vehicle.

10. The interface module according to claim 8, wherein the interface module is part of the host electronic control unit connected to a measuring device for at least one of monitoring and controlling operation of an electronic control unit of a motor vehicle.
