PREEvision
Model-Based E/E Development

PREEvision – This is
Model-Based E/E Engineering

The E/E Engineering Solution

Electrification, autonomous driving, connectivity inside and outside the vehicle: The onboard electronic network has become the brain of today’s cars.

The ever-increasing sharing of data within vehicles and to systems outside of the vehicle raises the complexity and makes the development of electric and electronic systems in vehicles, the so-called E/E development, more and more challenging.

PREEvision is a model-based development environment, that faces these challenges, and supports the entire E/E development – from architecture design all the way through to the final wiring harness.

Advantages

  • Design, management and documentation of complete E/E systems in one tool
  • Integrated traceability
  • Graphical modeling in diagrams
  • Full support of AUTOSAR methodology
  • Design of safety-relevant systems acc. to ISO 26262
  • Variant and product line management
  • Complete development from architecture to wiring harness based on one source

Application Areas

PREEvision Graphic User Interface

Model-Driven E/E System Development

PREEvision is the premier tool for model-based development of distributed, embedded systems in the automotive industry and related fields. This engineering environment supports the entire technical development process in a single integrated application.

It offers comprehensive functions for both classic and service-oriented architecture development and all aspects of an E/E system including requirements engineering, AUTOSAR system, software and communication design as well as wiring harness development. The integrated and model-based approach helps complex tasks to remain straightforward and controllable.

PREEvision supports the tried-and-tested system engineering principles of abstraction, decomposition and reuse and can serve as engineering backbone: it enables parallel work on a common database from multiple locations.

Highlights Version 9.5

New Features and Most Important Changes

  • High-Performance Computers
    Due to the computing demands, high-performance computers (HPCs) complement conventional ECUs in vehicles. PREEvision 9.5 provides a dedicated diagram to model HPCs including microcontrollers, microprocessors, and internal buses.
  • AUTOSAR Adaptive
    PREEvision 9.5 supports AUTOSAR Adaptive version 19-03 and facilitates the modeling of mixed systems of AUTOSAR Classic and Adaptive. A dedicated adapter translates between the software interfaces of both platforms.
  • Platform and Product Line Management
    The platform approach supports E/E development in levels or stages. Starting from a basic architecture for a vehicle platform, you can refine and detail the design downstream for single variants in an efficient way.
  • Server API
    The REST API allows web services and applications.

PREEvision's data model with dedicated abstraction layers

The PREEvision E/E data model is the foundation for a consistent model-based method of working from the requirements engineering to all the implementation steps. All the aspects of an automotive E/E architecture are modeled in an integrated approach. From the requirements and the architecture design all the way through to the final wiring harness.

In adopting this approach, PREEvision follows the three proven systems engineering principles of abstraction, decomposition and reuse and supports the modeling of product lines and product variants with various model layers.

Additionally PREEvision provides an integrated process and team support including test engineering and management, support for functional safety as well as tools to manage changes, defects and releases.
