Siemens’ Wiring Harness Software Take-Over Points to Greater EV Development

Future connected electric vehicles may be focused on the digital world but they will still need wiring harnesses which explains Siemens’ acquisition of a software specialist in the field.

Siemens has taken over COMSA Computer und Software, a Munich-based company which develops software for electrical systems design and wire harness engineering. Its LDorado suite claims to be the leader in automotive harness design and engineering software in Germany. It will now join the Mentor business, part of Siemens PLM Software, where it will add key harness engineering and design data analytics capabilities to the parent company’s product range.

Automobile wiring harnesses constitute the third heaviest part of a vehicle behind the powertrain and harness so any lightweighting work on this component has major implications on the future possible range for EVs.

Siemens said it plans to extend worldwide the delivery of new technology offerings that address disruption in the automotive harness industry caused by megatrends including autonomous driving and electric vehicles.

“The acquisition of COMSA is part of Siemens’ continued investment in technology for the automotive industry,” said Tony Hemmelgarn, president and CEO of Siemens PLM Software. “The combination of Siemens and COMSA solutions and specialist staff is unrivaled in the industry. Together, we will take electrical systems and harness engineering to the new levels needed to meet the demands of electric and autonomous vehicle development, and provide deeply integrated technical capabilities that will benefit COMSA and Siemens customers worldwide.”

Bishop and Associates estimate that in 2017 the worldwide revenue for the cable assembly market was $155Bn with approximately 30% of the market from automotive.
