light for the new Delta. " This was a very innovative project using more than 40 LEDs," explains Pete Moorhouse, VP, sales and marketing at OPTIS. " Legislation compliances were checked by OLSA ( a Fiat supplier and OPTIS customer located in Turin) using the OPTIS solutions. The added value our consulting department provided to Fiat was the opportunity to see the lit and unlit appearance of this innovative tail- lamp before committing to expensive prototype costs or production." Today, interior lighting detail and ambient lighting is becoming a must- have in the design of new vehicle interiors. " Increasingly we are being contacted by OEMs and Tier 1 suppliers to see how we can help them," reveals Moorhouse. In the past, OEMs demanded functional mechanical systems such as storage bins, cup holders, multi- functional instrument stalks and steering wheel mounted controls. Nowadays they want these items illuminated to create a feeling of ambient quality and luxury, increasing the complexity of the solution and adding the need for the simulation of these components from the perspective of light. " What was once the domain of luxury brands such as Mercedes- Benz and Bentley is increasingly becoming an everyday customer expectation for the average consumer. This development is adding to the already demanding pressures on these system designers. Simulation is one way in which OPTIS can add real benefits in terms of time, cost and perceived consumer quality."
Visual ergonomics As well as looking at how these components perform at the system level, OEMs are increasingly looking at how the complete systems work together in a complete package. Especially of interest is how these new features interact with each other, how they are perceived by the driver, and how they affect the visual ergonomics of the car's interior. More light and more innovative design and materials means more reflections and possible problems with legibility. Many car makers are turning to advanced simulation solutions to identify potential issues and provide alternatives to physical mock- ups through simulation to find solutions for optimizing the driver's vision. Using the Visual ergonomics package from OPTIS, customers are able to create accurate models of the car interior, using interior and exterior light sources, taking into account human vision thanks to OPTIS's unique human eye model. This model allows customers such as Fiat to identify potentially intrusive reflections, glare and legibility issues, in a simulated environment to eradicate these issues at source. Such a setup means that customers can still benefit from these advances in design and innovation without compromising the driving experience. " The fact that our solution is embedded in native CAD systems such as CATIA V5 means that any issues shown as a result of the simulation can be modified in the native CAD format and simulated and verified without leaving the design environment," explains Moorhouse.
