From parking aid to spacecraft control: Wherever electrical or electronic components are used to team up for the realization of advanced functions, leads, cables or complex wire harnesses are employed. Be it a small vehicle or a truck, a high-tech locomotive, an ocean liner or a space lab: the current must flow, and that safely and in orderly fashion. The planning and manufacturing of wire harnesses always involves a large number of enterprises. Therefore models for the cooperation between the suppliers, with controlled data flow, adjustment of levels of information and comprehensive standardization are essential factors of success.
Whereas in the case of rail cars or commercial vehicles the total number of individual leads is a challenge, the mass production of passenger cars requires special solutions for the extreme variety of equipment varieties because individual vehicle documentation does not make sense in this case. Especially in vehicle manufacturing, an ever increasing number of innovations are realized by means of electrics and electronics, the on-board supply system becoming more and more important for new solutions. At the same time its quality has meanwhile become a decisive factor for the reliability of the vehicle as a whole. For passenger cars alone, due to the increasing importance of on-board electronics the number of cable harnesses has increased fourfold since the nineties.
