The development of modern electric/electronic (E/E) architectures is a challenge today more than ever. Numerous development criteria must be taken into account, and classic vehicle domains need to be linked to new functions in the areas of driver assistance and autonomous driving. Completely new functions that are no longer limited to just the vehicle, but are also provided as services in the “IT backend” outside the vehicle, are emerging here. The introduction of serviceoriented architectures and powerful domain computers, Ethernet to on-board communication, connectivity gateways and, last but not least, increasing safety and security requirements represent profound and radical changes for every development organization. To master these complex development tasks successfully as a team, a development platform and E/E database, which can be implemented in different ways, are required.

The eye diagram is an analysis method for evaluating the signal quality of transmission networks with a moderate to high transmission speed. CAN networks can transmit information bit by bit from sender to partly distant receivers. The information transfer can, however, be easily corrupted by the network topology, cable length between the participants, line and terminating resistors as well as external electric influences. Both eye diagram analysis and serial bit mask analysis allow these influences to be identified and corrected early during the configuration phase of the CAN network.

Estimation matters. Many projects and smart business ideas fail for lack of delivering on time and budget. A common need in every field is thus to forecast and estimate. Estimation is an engineering discipline based on experience, data, transparent methods and common-sense. COSMIC, the Common Software Measurement International Consortium was created by an international group to develop a standard, ‘open’ measurement system and project estimation methods applicable to all types of software used in business and the real-time world. Estimation and measurement methods are rarely used properly in industry and the public sector, contributing to the high level of project failures and over-runs To improve both your project performance and productivity, we recommend starting right away with introducing or improving the estimation process with a closed loop of estimation, planning, measuring, and periodically improving your estimates. Read this award-winning paper and learn about best measurement and estimation practices.

„A fool with a tool remains a fool.“ Das wissen wir alle und trotzdem führen viele Unternehmen ein Requirements-Werkzeug ein in der Annahme, dass sich allein damit eine Verbesserung ergibt. Weit gefehlt! In der Regel sind die Mitarbeiter aufgrund der Komplexität des neuen Werkzeugs, aber auch des wahrgenommenem Formalismus frustriert. Klar ist, dass wirksames und effizientes Requirements Engineering (RE) ein passendes Werkzeug braucht. Automativierbare manuelle Tätigkeiten sind ineffizient und werden abgelehnt – egal wie gut die Intentionen dahinter waren. Doch vor dem Werkzeug steht eine umfassende Vorbereitung der Abläufe und Funktionen, damit das Werkzeug in die Umgebung passt. In diesem Beitrag zeige ich Ihnen, wie Sie das für Ihre Umgebung passende Werkzeug auswählen. Wesentliche Werkzeuge werden charakterisiert und bewertet. Sie erkennen, dass Prozesse und Werkzeuge systematisch eingeführt werden müssen. Das erfordert professionelles Veränderungsmanagement. Der Beitrag gibt zudem eine praxisnahe Übersicht zu aktuellen RE-Werkzeugen. Konkrete Praxistipps zur Tool-Auswahl und -Einführung runden ihn ab.

The benefits of lean requirements engineering can be related to several factors. Some such as better delivery accuracy or less rework create directly tangible benefits. Others, such as customer satisfaction, are more opportunistic and become tangible in the form of lasting good customer relationships with further projects. Overall, our experience has shown that a doubling of the effort for Requirements Engineering towards10 per cent of project budget in the areas of methodology, processes, training and tool support will deliver project benefits of more than 20 percent. That's a return on investment of more than 4, even by only considering the directly measurable benefits. Enough reason that you evolve your own requirements engineering towards 'Lean'.

In recent years, a number of independent standards have been created, all of which have affected processes and tools for diagnostic development – in particular ODX and AUTOSAR. At the same time, the systematic capture, management and tracking of requirements took hold, which also had a significant impact on processes, methods and tools. Is it possible to do without one or more standards? Is there a super-standard? Or can the standards and methods be combined with one another effectively and efficiently?

Transmission control units are often developed and calibrated for dozens or hundreds of vehicle variants. Not every possible variant is physically realised during development. Even the simulation of all variants on a HiL becomes infeasible with growing number of variants, since at least the control unit must then be physically realised and integrated into the HiL system. In such variant-rich cases, simulation of the entire system, including the control unit, becomes particularly attractive. Daimer, QTronic and Vector describe how Mercedes-Benz currently uses virtual ECUs to validate transmission control software for about 200 variants of the Sprinter series in a highly automated way on Windows PC.

Robert Bosch introduced the new CAN protocol CAN FD (CAN with Flexible Data rate) in March 2012. Key new features of this protocol are that it extends the useful data length from eight to 64 bytes and offers significantly higher data transmission rates. Based on its performance data, CAN FD is positioned between High Speed CAN (1 Mbit/s) and FlexRay (10 Mbit/s). It is ideal for filling the performance gap between these bus systems at low cost. This article explains, from the perspective of a tool supplier, what needs to be modified and the effects of such changes on CAN FD development and simulation. These modifications are made on various levels: from the hardware level to potential data ­formats and various communication layers.

It is equally as important to have a standardized charging process. This article describes Smart Charging and its standardization in the ISO 15118 standard. With Smart Charging, in addition to a power connection, the vehicle also establishes a communication channel with the charging station. Today,Vector is already providing a first implementation based on its MICROSAR IP communication stack.

The many different bus systems used in the development of electric/hybrid vehicles (EV/HEV) are pushing conventional hardware interfaces to their performance limits. A crucial factor in determining testing depth, analysis quality and simulation options is the degree of real-time performance in data exchange. Communication between vehicle networks and the test and simulation tools is of primary importance here. To satisfy these heightened requirements, Vector has added a modular high-performance interface with integrated real-time computer to its interfaces product line. This interface’s realtime performance leads to short deterministic cycle and response times and enables flexible use in the EV/HEV development field and in numerous new application areas.

Diagnostic functionality is typically implemented very late in the development cycle of an Electronic Control Unit (ECU). Suitably configured diagnostic test systems are usually not available until shortly before production startup. An informal never-ending requirements phase further aggrivates this situation. The solution of Stuttgart-based Vector Informatik GmbH: (1) Formalize Requirements Management and fill in the gaps between the customer specification and the requirements specification with the help of OEM-specific templates; and (2) implement diagnostic requirements in a XML database. With this approach (Frontloading) the total effort required to implement the diagnostic protocol can be reduced by a factor of 6 to 7. This creates in a win-win situation for both suppliers and OEMs.
