Shedding pounds in automotive wiring

Intra-vehicle networks describe as the exchange of data within the electronic control units (ECUs) of the vehicle, which are involved in vehicular applications. Increasing vehicle complexity, including all the sensors associated with autonomy, if felt directly in the wiring harness, resulting in the wiring harness becoming the 3rd highest cost and 3rd heaviest component in a car. Corinex's BPL solution can reduce weight and cost in vehicles by using the same wires for power and data, especially for EVs and autonomous driving.

Automotive trends create new challenges for wiring harness

As the complexity of vehicular distributed systems increases rapidly in modern vehicles, several hundreds of devices (sensors, actuators, etc.) are being installed with wiring cables connecting these devices. In addition, with the development of electric vehicles and autonomous driving, extra electrical wiring and a multitude of hardware redundancies are all contributing to the significant weight increase of a modern vehicle. For example, the introduction of the electric powertrain alone adds about 30% more weight compared to an internal combustion engine powertrain. According to Cowen Research, the wiring harness is in fact the third-heaviest component (behind the chassis and engine) in most luxury automobiles. Any technology that reduces this weight directly contributes to fuel economy, which is one of the most important factors in bringing a competitive and successful vehicle to the market.

"The wiring harness is one of [the] three heaviest subsystems in many vehicles - as much as 150 Ibs. Today's cars contain some 1,500-2,000 copper wires, totaling over 1 mile in length."

- Doug Burcicki, Director of Integrated Electrical Systems at Mentor, a Siemens Business

Lighter, cheaper, and simply better

The never-ending development of new technologies and their addition to modern vehicles leads to conflicts between the technology content that vehicle manufacturers try to integrate into their vehicles, and the weight, cost and packaging space required for wiring harnesses. How can today's automotive manufacturers solve these conflicts? One solution could be using ultra-small diameter wiring. Unfortunately, the industry is still struggling to develop a sufficient number of terminal substations for large-scale migration. Therefore, finding alternatives to specialty cables becomes crucial.

Corinex' BPL technology offers a new possibility for car manufacturers to reimage the automotive wiring. As more cameras, displays, and other electronic components are integrated into the modern car, the amount of data will only increase in the future. Corinex' BPL solution enables transmitting data and signals via existing and standardized wiring, and multiplexing these signals onto one shared cable to where multiple devices are connected. With the benefits that Corinex BPL technology provides, engineers can perform tradeoff studies to optimize wiring materials, component placement, and routing for minimal harness weight, cost, and bundle diameter.
