Nissan, Siemens digitalise production lines for new e-vehicle Ariya

Siemens as supplier of automation and industrial software is cooperating with Nissan to build production lines for the new all-electric crossover Nissan Ariya at the latter’s manufacturing plant in Tochigi, Japan. 

Nissan had already been using the Siemens Digital Industries software portfolio to optimise design and production. End-to-end digital threads enable Nissan to connect a wide variety of sources of information across product lifecycle management (PLM) platforms.

“The successful launch of the new production lines is a milestone in the collaboration of the two companies,” says Cedrik Neike, member of the managing board of Siemens and Digital Industries CEO.

“Climate change and stringent environmental regulations are powerful drivers for the development of electrified powertrains,” said Neike. “We will bring in all of our cutting-edge technologies to this collaboration to enable a highly flexible, efficient and sustainable automotive production.”

Teiji Hirata, corporate VP at Nissan Motor’s vehicle production engineering and development division.

“At our Nissan Intelligent Factory in Tochigi, we are building the future of mobility,” said Hirata. “It enables us to not only improve the work environment but also to realize a zero-emission production system.”

The system architecture of Nissan’s newly developed electric powertrain aims to standardise the processing and assembly of the powertrain. It includes Siemens’ safety PLC Simatic S7-1500, ET200SP distributed I/ O module as Siemens One Single Solution. 

Profinet creates end-to-end communication from the field to the management level, and the engineering framework TIA Portal has also fully integrated all automation devices. 

This enables complete access to the entire digitalised automation process, from digital planning to integrated engineering and transparent operation. More intelligent automobiles require more and high-performing Electronic Control Units (ECUs) in the vehicle — as is the case in the new Nissan Ariya. 

The Siemens diagnostic commissioning system Sidis Pro, which has already been deployed in many automobile companies around the world, is implemented at Nissan’s new production line for data writing into ECU and verifying automotive electric components. 

The same software can be used for different applications, enabling system standardisation and ensuring that fewer resources perform for more tasks even at other production sites.
