John Deere: Forging new pathways in testing ISOBUS task controllers - Simulations replace inflexible and time-intensive test methods

The inter-system and inter-OEM compatibility of ISOBUS-conformant devices lets farmers interconnect tractors and implements from different manufacturers in any desired combinations. As easy as this may seem from the user’s perspective, the level of effort required in the device development side is high, especially in the testing phase. A look at John Deere shows that conventional industry methods for testing electronic components are now often running into their limits. An incomparably faster and more efficient means for attaining the desired goal is automatic test sequences with a simulated implement environment. ...

CAN FD: Fast measurement and reprogramming

CAN with a flexible data rate (CAN FD) is a technological evolution of the CAN bus. The complexity of the technology is equivalent to the standard CAN bus but it offers a significantly increased bandwidth. CAN FD is therefore an alternative for FlexRay or Ethernet Networks. The network specialists at Vector investigated two typical applications, Measurement of ECU internal signals via XCP and ECU reprogramming, using the CAN FD bus system.

Riding on the Razor's Edge – Optimal Parameterization of an Engine Controller for Drag Racing

In calibrating engine controllers for production vehicles, electronic developers typically work with engine test stands and numerous test drives over different route scenarios. However, no such tools are available for special engine controllers used for drag racing. Using Vector’s CANape measurement and calibration tool enables an engine controller to be calibrated for top performance without using a test stand while staying within a tight budget even under the continual risk of destroying the engine after just a few test runs.

Daimler: Analyze large quantities of measurement data rationally and flexibly

On test benches and in durability tests, automotive OEMs collect important information on the behavior of vehicle components under realistic conditions. However, in view of the enormous quantities of data that are generated and their complex interrelationships, it is often a time-consuming process to subsequently identify and analyze the relevant data sets. To accelerate the analysis of measurement data in testing its automatic transmissions, Daimler AG relies on automated data evaluation by the CANape measurement and calibration tool from Vector.

Testing in heterogeneous tool landscapes: What kinds of interfaces are available?

Many automotive software tools provide outstanding services custom-tailored to their specific fields. A common assumption would be that coupling multiple expert tools together would create a valuable development environment for ECUs, but the tools often just end up being isolated applications which can’t interact with one another or only in a limited capacity. The simple fact is that every modern tool integrated into a larger system requires extensive options for interacting with its environment.

Seamless Communication Tests in ECU Development for the Volkswagen Group

In ECU development, the specific test implementations play a special role for suppliers of Volkswagen AG (VAG): they check for network conformity, assure smooth interplay of the numerous ECUs and are a key criterion for final acceptance by the automotive manufacturer. Using VAG-specific test software, developers and suppliers conduct automated tests according to VAG specifications DUM.857.BE.1 and DUM.000.AC.A for High-Speed CAN and Network Management High which ultimately saves a lot of time and expense.

New Communication Paradigms in Automotive Networking - Ethernet and CAN FD Are the New Trailblazers

CAN is the prevailing bus system for communication between electronic control units (ECUs) in today's vehicles. The communication demand has increased dramatically in recent years, and vehicle manufacturers are now reaching the limits of vehicle networking with CAN. Ethernet and CAN FD provide higher bandwidth and are taking over some of the tasks of existing bus systems. The higher bandwidth is one aspect, but also of high relevance is the introduction of new communication paradigms.
