Abstract
Due to the requirement of cost and development time reduction
all automotive OEMs and suppliers need to increase their
productivity. At the same time the number of electrical systems in
a modern vehicle runs into hundreds, and the design and
optimization of the wire-harness connecting all components together
is becoming a significant design task. Optimizing the cost and the
quality of the harness for satisfactory operation under a wide
range of conditions is important to keep the vehicle cost
competitive. The use of a simulation tool to help in wire sizing
and test, tightly coupled to a dedicated harness design tool is
getting indispensable for this task.
The different components will be integrated together with the
harness on a virtual platform. With this concept it is possible to
perform functional tests or to do FMEA quite early in the design
cycle. The paper will show the development process from the first
functional schematics over the cabling diagram, down to the
manufacturing data in a bundle drawing. Furthermore it will bridge
the gap between 2D CAD and 3D Mechanical CAD. The design of a Power
Window System will serve as a demonstrator for this new development
flow.
