Vehicle manufacturers are constantly faced with the challenge of balancing fuel efficiency and safety against the demands for greater performance and lower development costs. Driven by these needs, a wide range of computer-aided modeling tools has emerged, covering all aspects of the dynamic behavior of vehicles. However, these tools tend to be very application-specific and use computationally intensive numerical methods, such as finite difference and finite elements.
/> While these are useful for the off-line stages in the design process, where time-to-result is not too critical, there is an increasing demand for faster simulations to the point where high-fidelity models need to be run in real-time for hardware-in-the-loop (HIL) testing. The demand for better understanding of the dynamics, and the ability to produce high-fidelity physical models of vehicle systems that can be used in HIL systems to test prototype controllers, has reached a critical point for many companies.

This article explores how the use of model-based design and virtual prototyping allows automotive manufacturers to reduce design and prototyping costs significantly while fulfilling the demands of governments and markets.
