In-vehicle Network (IVN) Stacks
AVB, TSN, DoIP, UDS
Excelfore has implemented Ethernet AVB/TSN and has installed it on a number of different operating systems and ECUs. Our eAVB/TSNTM was the first implementation to be certified by AVnu for both the ‘talker’ and ‘listener’ functions. Our eAVB/TSN is running in cameras, video displays, headunits, even ECUs. It also runs in network gateways so that CAN, LIN, and other busses can be reached by Ethernet. It has been ported to automotive-grade Linux, Android, and Real-time OSs (RTOS) including FreeRTOS.
With Diagnostics over IP, UDS diagnostic services are used over TCP/IP and Ethernet. Diagnostics over IP extends the functionality of UDS to all networks. Excelfore implements DoIP in its eSync Client, so that OEMs have access to this diagnostic technique for the entire vehicle, whether the ECU is Ethernet-based or CAN.
Extending Software Updates
Diagnostics-Over-IP (DoIP) can be used to extend the reach of over-the-air software updates. Use of a DoIP Gateway permits discovery of all components in the vehicle system and establishes an IP-addressable route to each one. It also permits software access to registers within each component, and it provides the method to reflash the component.
In the service bay, troubleshooting and repairs are simplified because all components in the system are accessible from one test port. This can be diagnostics equipment located in the dealership, or it can be tests run remotely from the OEM.
Unified Diagnostic Services (UDS) is a diagnostic communication protocol for ECUs that has been widely implemented in CAN-based systems. There are 26 basic UDS commands, grouped into six categories. They permit data transfers in both directions and allow an external test system to issue various commands to the ECU and receive responses. The ECU can be reset or reflashed as well. Excelfore supports UDS and uses it as part of the eSync Client to communicate with all UDS-compatible devices within the vehicle.
