Functions are strengthened by developing skills areas. Specialists and experts design processes to define, structure and sustain skills in areas of expertise vital to Renault, such as onboard software, electrical engineering, electronic component technology, electro-magnetic compatibility and radio frequency.
 
These function supports are essential to vehicle projects.

Specialists can acquire experience either through solid industrial work achieved previously or through a career at Renault, throughout which they perfect their skills to become function experts and references in their professional field.

Wiring engineering
 

The wiring sector has both a function and project structure. The function coordinates innovations, develops and disseminates knowledge on wiring techniques and components (attachments, relays, connectors, etc.), notably through expertise. Projects are managed by Functional Development Group (GFE) coordinators and Functional Production Group (GFS) coordinators, who develop vehicle wiring worldwide from design through to end of service life, working continuously with projects, DIESE sectors, vehicle design and plants.

Electrical and electronic architecture
 

Working with projects and all sectors of the DIESE that handle electrical parts, electrical and electronic (E/E) architects build pre-project vehicle structural design (physical, electrical, electronic) and monitor its evolution by approving prototypes and integration platforms  through to industrial production. They establish the architecture, coordinate inter-system integration, and are responsible for proposing and gaining approval for the policy of the E/E architecture function.

Electronic application sectors: Bodywork, Chassis and Powertrain
 

Working with the Bodywork, Chassis and Powertrain departments, Electronic Development Coordinators (PDEs) are responsible for developing the numerous ECUs fitted on vehicles by these departments.
Coordinators at the DIESE do not design the electronic products themselves but specify characteristics in terms of hardware, software, functionalities, the environment, etc. for regularly audited suppliers to ensure the products meet required quality levels.

Electrotechnical
  

Electrotechnical designers develop technologies, components and systems linked to the production, storage and management of electrical energy. They coordinate the development of onboard electrical energy supply systems – alternators, starters, batteries, distribution ECUs – and electrical energy management systems, together with innovative management systems. They are also responsible for drawing up and approving technical policies.

Diagnostic
  

Diagnostic designers and architects design vehicle diagnostics for plants and after-sales. They develop technical policies in compliance with international standards and electrical management processes. They also design tools and monitor their implementation in plants and after-sales. They are in constant interaction with the project phase, volume production, other DIESE sectors, and after-sales networks and plants worldwide.

Inter-system
  

Working with other DIESE sectors and the Product Department, inter-system coordinators help construct the electrical, electronic and electrotechnical offering throughout the project, and also build the simplest, most intuitive and cross-functional human-machine interface possible. They contribute to design robustness with a clear and well-detailed description of the features of cross-functional specifications.
