The wiring harness for vehicle power and signal distribution has become a major chokepoint for automotive makers, as the number and complexity of onboard electronics systems proliferates. Siemens is a major player on the design and engineering front and has just beefed up its capabilities by acquiring COMSA Computer und Software, a Munich-based developer of software for the electrical systems design and wire harness engineering. Increasingly sophisticated infotainment systems, EVs (Electronic Vehicles) and autonomous driving systems are the three main factors expanding the size of vehicle wiring harnesses to the extent that they are now easily the third largest component of vehicles after the engine and chassis, both by weight and cost. Comsa’s LDorado suite will now add design and…
