Integrated design tools for model-based development of innovative vehicle chassis and powertrain systems

The paper provides a quick overview on system integration methodologies for advanced vehicle chassis and powertrains through an extension of the model-based design concept. Physics modeling and Driver-In-the-Loop (DIL) simulation techniques are described with an eye on the related hardware and software tools. In greater detail, the design workflow pivots around a state-of-the-art device: the Driver-In-the-Loop simulator, where subjective, “human” factors can be taken into account together with objective, engineering factors. A framework of complementary tools with integrated functionalities supports the designer in order to merge traditional chassis engineering with advanced vehicle dynamics skills and modern control system design. An interactive design framework is proposed in order to report the authors’ experience. A self-developed utility for suspension and steering design, specifically conceived for intuitive integration in the design process, is also presented.
