Tag: fault simulation

We are pleased to be equipping the automotive competence center of the Chamber of Crafts Frankfurt (Oder) – Region Ostbrandenburg in Hennickendorf, which is in the course of being set up, with the latest simulation and diagnostic technology for its innovative teaching concept! As one component of the “diagnostic test stations” supplied, the Softing TCS simulation boxes enable the mapping of vehicle networking via Automotive Ethernet (DoIP) as well as classically via CAN-FD. This makes it possible to simulate realistic error scenarios in vehicle communication and experience them in a practical way.

Simulation in test preparation enables the verification of test routines and the entire test setup, which reduces the time required for troubleshooting. ODX-based diagnostic simulation improves test sequences, minimises test effort and ensures accurate fault detection. In our short Solution Spotlight video, Thomas Blocher explains the use case and shows how an ODX-based simulation project can be easily created and customised with Softing TCS.admin.

Functional safety is the focus for Arnold NextG in the development of the unique NX NextMotion central control unit. For this reason, the technology forge Arnold NextG relies on the innovative solutions of Softing Automotive for the development of the control unit for automated driving!

Modern vehicles contain extensive hardware and software functionality that has to be checked, verified and safeguarded from all sides. This task is particularly challenging because it takes a longtime during vehicle engineering before these components are installed in a real vehicle and can thus be tested in a real environment. With individual function and hardware-in-the-loop (HiL) test systems, any conceivable test scenario can be covered and easily simulated in the laboratory without risking real vehicles or endangering the lives of test drivers.

HV insulation fault simulations are used to test and validate safety-relevant system functions, either during the engineering process or also after repairs carried out by after-sales service or the repair shop, or directly on the vehicle.

In daily operation, ECUs in the vehicle are exposed to a wide range of environmental influences, such as vibrations, strongly fluctuating ambient temperatures and high humidity. The components must therefore be able to handle all conceivable faults. For the test, these faults are simulated on the ECU pin and the respective behavior and diagnostic entry documented. Typically, such fault simulations are used for function tests during development, for testing, release and validation of ECUs and components, as well as for integration validation during HiL testing or at the Functional Mock-Up (FMU).

It is a long journey from the start of engineering to the installation of all vehicle components and ECUs in the production vehicle. Comprehensive testing of the electronic components during the entire engineering process is essential. This is the only way to thoroughly safeguard and optimize hardware and software functions. Errors can be detected and remedied quickly – the earlier the better.
