As the key driver and enabler of future functions and features, electronics and software is set to represent up to 35% of the production cost of an average vehicle. Considering that 52% automotive recalls are due to electrical system failure, automakers are more focused that ever on improving the vehicle safety systems. This and environmental issues are promoting the use of sensing technologies in modern vehicles. Features like smart safety systems, pedestrian sensors, personalized driving experience and new emissions standards create greater demand for embedded systems.
Dassault Systèmes (DS)' Automotive Electronics & Software Engineering & Manufacturing solution addresses specific challenges associated with automotive electronics and embedded systems development. Mechatronics design toolset is provided by this solution to enable synergetic integration of mechanical and electronics content into an automotive module. This includes integrating circuits (chips), printed circuit boards (PCBs), embedded software, as well as mechanical components, all with varying development lead-times and lifecycles that must be coordinated stringently to avoid any delay. By providing a single virtual product definition for all mechatronics data, engineers have access to accurate, up-to-date information, which enables cross-functional teams to iterate more effectively.
With Dassault Systèmes solution, testing is performed on the electronics system as a unified entity, helping automakers to meet higher product reliability and performance standards. This is crucial as the life span and reliability of automotive electronic systems and their interconnecting components remains a major concern, especially considering that thermal and mechanical loads increase as the electronic module size decreases. Dassault Systèmes' product simulation offering is heavily used by automotive electronics suppliers and the OEMs to supplement and replace physical testing, especially for under-hood electronics.
As automakers are bringing in teams from multiple organizations, there is usually a need to accommodate multiple CAD systems. Multi-CAD support is built into the Automotive Electronics & Software Engineering & Manufacturing solution so that teams can freely review and exchange data while tracking changes and configurations across multiple CAD systems. As mechatronics modules can be developed by or sourced from various suppliers across the globe, this solution also provides multi-site and supplier collaboration functionalities so that product development can be more reliable, faster, and around-the-clock.
The CATIA electrical applications enabled us to define the wiring requirements in the early stages of the design process, making it possible to reduce the weight of the shell and chassis by 3%.
