1 Preamble

Innovations in automotive industry like adaptive cruise control or multi media passenger entertainment systems nowadays define themselves by electric and electronic components. As the electrical wiring system builds the essential infrastructure for automobile electronics, the wire harness becomes increasingly complex. This need for increased complexity comes along with the minimizing of design time and shortening of lead times.

Therefore the collaboration of car manufacturers and harness suppliers is a challenge. The traditional way that a supplier receives harness design data from the car manufacturer has to change. Instead of various drawings and lists in proprietary formats he needs a specification, which describes the wire harness in its entirety so that the manufacturer can plan the manufacturing and build the harness, based on the data he receives. Such a specification should be based on standards to fulfil the requirements for open development partnerships.

Figure 1: Harness Design Process

The objectives of the VDA Working Group “Car Electric” are the harmonization of requirements and the development of recommendations for the exchange of product data in the area of car electrical systems.

This recommendation is a result of the working group and has been developed with the participation of major OEMs and harness suppliers: The “Harness Description List”. This specification is also known under the name “KBL”, which stands for “Kabelbaumliste”, the German translation for “Harness Description List”.

The recommendation defines how harness design data coming from various sources like 3D CAD systems or CAE system can be represented in an aggregated view. It also describes how the international standard ISO 10303-212 “Electrical Design and Installation” [ISO10303] should be used for this purpose.

2 Goals of the recommendation

The goal of this recommendation is to specify the information that an OEM should make available on harness design for suppliers or other down-stream processes like EMC (Electro-magnetic compatibility).

The specification abstracts from OEM specific processes. By that it provides the basis for

- Reference standards for data quality

- Standardized viewing solutions

- Independency of harness data from proprietary software tools

- Simple comparability of development status and variants

- Standardized data exchange processes

It further avoids thereby the repeated development of engineering data.

3 Scope and responsibilities

The typical harness development process starts with the system design where the functionality of the new developed system will be described. The top level view gives the overview of all items needed. With wiring diagrams engineers start to define the parts needed to fulfil the expected functions. Components are selected according to the required specification and are documented in part lists. Connections are defined to combine the components logically. The first harness concept takes place, the position of the components and paths for wires are planned and described in wire lists and harness layouts. The netlist (connection list) can be used to start the harness routing.

This recommendation defines how electrical/logical data coming from CAE systems (usages of components, connections, etc.) and topological data coming from 3D CAD systems (routing of cables and bundles) should be represented in an integrated way:

- Part identification including versioning, references to car projects or supplier information

- Harness, variants and options

- Modules to support modular design

- Harness components like connectors, wires, fixings, grommets or accessories

- Connectivity lists

- Part usage lists

- Topology and routing

- References to drawings or manufacturing documents

8 XML Representation of the Harness Description List

This recommendation specifies a XML schema for the XML based exchange of harness design data. The XML schema has been derived from the objects defined in section 6 and the UML model given in section 7.

The projection onto XML schema has been guided by the rules given in the OMG standard PLM Services ([OMGPLM]). Figure 21 shows the mapping exemplary for the object Part.

A complete listing of the XML Schema is given in Annex A.
