Abstract
This Intelligence Set includes the fifth edition of our vehicle electrical
wiring report, along with profiles of Alcoa, Delphi, Lear, Leoni, Valeo and
Yazaki.
It offers excellent value for money and will allow you to discover where the
market is heading, what the latest innovations are, and how your competitors
are performing.
The need to reduce cost, cut emissions, improve fuel economy and safety are
the main forces driving the electrical and electronic distribution systems
(EEDS) market. Manufacturers point out that the increasing use of electronics
hard- and software can significantly help address these concerns.
The popularity of hybrid vehicles is also placing demands on EEDS. For
instance, the additional voltage level for the electric drive must be safely
distributed between the assemblies of equipment. Furthermore, the already
existing demand for weight reduction becomes far more critical when the extra
weight of the electro-motor and hybrid battery is considered. In today' s
hybrid vehicles, the conventional electrical system and the hybrid electrical
system are, for the most part, separate.
For manufacturers, the increase in the content and complexity of electrical
and electronic components also requires a broader overall design perspective.
This shift in design philosophy is, as Lear Corp describes it, "moving from
the wire itself to the wire ends", reflecting a view that design should
include both the wiring and the electromechanical and electronic devices to
which they are connected.
In this fifth edition report, just-auto has added an additional 3,000 words
over the previous edition, reviewing the key market drivers for vehicle
electrical wiring systems, and updating the market analysis. Following our
market overview in Chapter 1, Chapter 2 presents overviews of the latest
suppliers' activities.
Also, we run through what' s been happening in the emerging markets in this
sector and we provide 2008 supplier market share percentages of wiring
harnesses for the major producing regions, plus the world market as a whole.
It' s in chapter 2 where you' ll find our latest historic and forecast data for
wiring harnesses. We provide 2005 to 2016 market values in North America,
Western Europe, Japan and China for vehicle wiring harnesses by application,
e.g. separate data rows for engine harness, roof harness, floor harness, etc.
In total, we split the market into seven sub-categories. Also included is our
actual/estimate, best- and worst-case scenario data.
Plus we have included a detailed interview that just-auto conducted with
Intedis' managing director, Pascal Degardins in June 2009.
Extract: just-auto: When we think about the conventional wiring system
architecture, presumably adding a device means adding a new wire. Or does it?
Are you now seeing more and more inter-connects which are protocol-based? What
are the implications?
Pascal Degardins: New functions imply new wires. Multiplexing can only be used
between electronic units and act as the link between some intelligent sensors.
The majority of sensors and actuators are hard wired. The silicon industry is
making strong progress in integration using cost-effective single chip
solutions. This has led to an increase of smart sensors and actuators. Silicon
manufacturers, however, face a difficult challenge for two reasons. First,
wires are cheap. Second, automotive requirements for electronics are more
demanding than for consumer electronics.
Chapter 3 Technical review
Here we set out a review of recent innovations in this sector, including:
- Wire in composite packaging
- Sensor integration in ECUs
- Ultra-thin cabling
- Hydrolysis-resistant materials
- Non-lead stabiliser compounds
- The latest wiring harness development standards
Also provided is an interview with Gerulf Kinkelin, director of research and
innovation at PSA Peugeot Citroen, about AUTOSAR, the electric/electronic
architecture standards group made up of some of the world' s leading vehicle
manufacturers.
Chapter 4 Manufacturers
This chapter provides profiles of the major manufacturers, namely Alcoa
Electrical and Electronic Solutions, Delphi, Intedis, Lear, Leoni, Sumitomo
Wiring Systems and Yazaki.
