APP-Based Diagnostics of E/E Systems with ISO Standardized Technology (MVCI, ODX, OTX, and UDS on DoIP)



SAE 2016 World Congress and Exhibition
Authors Abstract
Passenger cars are equipped with an OBD connector according to SAE J1962 / ISO 15031-3. Passenger cars that support ISO UDS on DoIP use the same connector with Ethernet pins according to ISO/DIS 13400-4 (Ethernet diagnostic connector).
If external test equipment is connected to the Ethernet diagnostic connector via a 100BASE-TX cable with the RJ45 connector at the tester, a VCI is not necessary anymore.
With a device that fits the Ethernet diagnostic connector physically and acts as a converter between the Ethernet signals and WLAN, external test equipment that supports wireless communication, can be connected to the vehicle. Examples for such wireless external test equipment include Android/iOS- based smart phones and tablets with purpose-made applications (APPs).
The software components of external test equipment are standardized in ISO 22900 (MVCI). The MVCI D-Server processes data in ODX (ISO 22901) and sequences in OTX (ISO 13209).
For an APP-based wireless communication with a vehicle that supports Ethernet, the MVCI D-Server, the ODX data and the OTX sequences have to be implemented on operating systems like iOS or Android.
The APP-based tester is entirely based on international standards and supplements the functionality of a workshop service tester.
