The Electrical Net of a car

The electrical net is the infrastructure for signaland energy transport between all electricalcomponents

The electrical net consists of various wireharnesses. The main harness is normally a combination of

modules that are configured due to the customers choice. Some million valid configurations can bepossible.

Minor harnesses are designed in variants, whereeach configuration has a specified part number.

The Design Process and Design Tools

Nearly every car manufacturer has a different approach to design harnesses that fits to his specific logistic concept.

All core design processes can be split into these phases: Functional Design System Design Installation and DMU Harness Design Documentation / Data Output to Manufacturing

There is no end-to-end design tool available, that offers applicable solutions to all of these phases.

Thats the reason, why VW developed VOBES.

Aspects Of VOBES Until 2003

VOBES 1st generation integrated ECAD and MCAD data achieved a consistent design data flow from system

design to documentation had a lot of outstanding functionality

used proprietary internal interfaces used proprietary internal data formats needed complex userware in CATIA and LCable was expensive to maintain

Evolution Into The 2nd Generation Of VOBES

Key Challenges extract more value from the existing data by extended

use of design data within the design process improvement of performance integration of new generations of CAD editors smooth evolution with parallel use of tools

Key Solution modular toolchain with neutral interfaces integration of the best tools available for each phase

Transition Towards The Modular Toolset

Volkswagen builds the future Electrical System Development Process

on standard data formats and on amodular software architekture

with a file-based exchange ofdesign data.

Conclusion

KBL and its derivates

have a data model to represent harness data,

help us build neutral interfaces between applicationswith different scope and

enable us to modularize the tool chain,

allow us to extend the usage of design data along the product process and

can also be used to forward harness data to our suppliers
