Guided and automated calibration and validation of powertrain systems
Powertrain system calibration and validation faces multiple challenges. These include complex electronically controlled systems with elaborate embedded software that are used in multiple vehicle variants; demanding requirements regarding pollutant emissions, fuel consumption, and on-board diagnostics; limited numbers of test vehicles; and strict …
Standard goes off-road
The AUTOSAR standard, originally conceived for automobiles, is now finding application in agricultural and construction vehicles. For cost and quality reasons, this makes a lot of sense. However, the manufacturers of these vehicles should plan implementation very carefully and precisely.

Are you secure?
Automotive electronics are undergoing radical change. As developers, we face major challenges with new powertrain concepts, [partially] automated driving, and connection to the Internet of Things (IoT). We are already capable of implementing high-quality electronic systems in large numbers with the highest safety requirements, and this will continue to be important. However, it will no longer suffice …
Methods and tools for the development of vehicle systems: Measurement, simulation, virtualization
Global competition, high safety requirements, and automotive emissions and fuel consumption call for advanced electronically controlled systems. These need to be developed, tested, and calibrated within a prescribed time and on a limited budget. To do this, hundreds of different driving situations and operating conditions …
Recording large volumes of measurement data in the vehicle and on the test bench
Together with interface and drive recorder modules, a newly developed ECU interface allows users to record large volumes of measurement data from ECUs and other sources. ETAS shows how these measurement data volumes can be captured and then used for complex analyses.
Successful security tests using fuzzing and HiL test systems
In automotive development, it is a given that hardware-in-the-loop (HiL) systems undergo systematic testing to ensure functional safety. These tests verify whether the tested system behaves correctly and reliably as per functional requirements, and whether it goes into safe mode in case of a malfunction. Safeguards against unauthorized access require similar …
In order to meet the strict new RDE testing conditions, the behavior of combustion engines must be optimized across the entire speed-load range (“global”). This goal can be achieved with the help of Gaussian processes. These machine learning methods allow the engine behavior at the test bed to be simulated with maximum probability. With the help of the new method, the measurement effort at the engine test stand could be reduced by 75 …
Do I need an AUTOSAR authoring tool when I want to test AUTOSAR software components? In this article, Steffen Roser (Support Engineer Software Engineering at ETAS), answers this questions and provides hints where to find further documentation and tutorials to get you started!
In INTECRIO under menu Experiment there is the feature "Open Experiment". Sometimes it is gray (not active). In this article, Steffen Roser (Support Engineer Software Engineering at ETAS) describes how to activate this feature.
