Today’s vehicles feature a wide range of ECUs. These control and monitor various electronic areas; errors which have occurred are saved permanently. For their evaluation there are all kinds of different requirements in the various phases of the vehicle life cycle. This is why the market needs a flexible vehicle interface to cover these use cases as comprehensively as possible. The new VIN|ING 2000 from Softing Automotive supports both wired and wireless access and, what is more, is already prepared for future remote use.
In the automotive industry, diagnostics for ECUs and vehicle functions is constantly gaining in significance, after all, trends such as (semi-)autonomous driving demand increased predictability of the state of all components involved. An important basis for this is the programming language OTX (Open Test sequence eXchange) which, in the form of standard ISO 13209, describes diagnostic sequences for vehicles. One particular advantage is its suitability for a multitude of different use cases.
Vehicles are increasingly connecting themselves with their environment: with other vehicles, parts of the infrastructure, the cloud. And this is in fact the key to new functions such as autonomous driving. Together with the increasing electrification of vehicles, this is placing even more demands on diagnostics - but at the same time is also presenting completely new opportunities.
Vehicle diagnostics has been working the same for years: Plug in an adapter and use an expert system to localize the problem. The fault will then be rectified on the basis of the data gained. Updating ECU functions takes place in exactly the same way. In comparison to this procedure, considerable time and cost savings will be able to be made in the future for both functionalities with the extension of the vehicle into the cloud. And this will also lead to a considerable improvement in diagnostic quality.
The increasing complexity of ECU software is seeing a parallel rise in the scope of the diagnostic functionality it has to cover – all the more so since testing is no longer limited to valid diagnostic services and parameters. Rather it is also necessary for the response to invalid service and parameter queries to be included in diagnostics. Testing the temporal communication behavior also has to be covered. These additional requirements play a significant role particularly in access scenarios of remote diagnostics.
VCIs (Vehicle Communication Interfaces) in a number of variations are used throughout the entire vehicle lifecycle so a test system can communicate with the vehicle. The newly developed VCIs of the VIN|ING product family from Softing take the specific requirements of engineering, manufacturing and after-sales service into account. Highly integrated and powerful hardware and software components make it possible to integrate the entire diagnostic system on the VCI. This means the VCIs are perfectly equipped for the various scenarios of remotely accessing a vehicle.
