Model-Based E/E Development with PREEvision

From Architecture Design to Series Production

PREEvision offers a comprehensive modeling language to describe all aspects of E/E systems. All engineers involved in the development process find tailored diagrams and editors for their work. And all in one integrated tool. What’s special about PREEvision: Everybody involved works in the same development environment, with the same data, in the same data model. In here, the complete e/e system is designed, managed and documented. For optimum collaboration within globally dispersed teams, PREEvision offers multiple functions.

E/E Development for Future Vehicle Innovations

An integrated, model-based approach from architecture design to series production

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 service-oriented 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.

Universal Management of Requirements in Functional Development

Case Study

MAN Diesel & Turbo SE uses PREEvision as its requirements management tool in the functional development of fourcycle engines. Around 50 engineers work in parallel on current and future generations of controllers.

They define the interfaces between functions and establish parameters for later engine calibration. PREEvision currently manages around 1500 individual requirements for approx. 20 primary engine functions (I/O, parameters, test specifications). In productive application cases, requirements management, the test specification and the software architecture are currently generated by toolkit elements that are later reused.
