There is increasing pressure on the automotive industry to create vehicles that take advantage of alternative energy sources. The ever increasing cost of fuel and the more stringent emission standards require that new technologies be developed to meet those needs. At the same time, the automotive industry needs to keep the consumer happy by meeting the performance requirements it has been able to deliver, and wishes to continue to benefit from the infrastructure already in place (gas stations, fuel delivery, etc.). Companies like Toyota, GM, and Ford have expended much effort to bring such systems to market. Developing a system that merges new technologies (advanced electrical power sources and drives) with existing technology (gasoline powered engines) in order to drive a vehicle requires an uninterrupted development process that maximizes the contribution of all engineers participating in the design. Such a system requires that the analysis of the design take place at the system level in order to understand the effects of integrating multi-domain systems. In this paper, we will discuss how Model-Based Design was used to model and develop the electrical system of a hybrid-electric vehicle. Specifically, this paper will address the following points: 1) Designing and testing a Hybrid-Electrical Vehicle (HEV) behaviour with no physical prototype 2) Designing an accurate and comprehensive representation of the system, in order to examine the integration of the electrical and mechanical systems, and to integrate the control strategy early in the development process in order to thoroughly explore control design options. 3) Define testing scenarios reusable on the final system 4) Test power management control unit in real-time This paper will also discuss the results and benefits of designing such a complex, multi-domain system using the Model-Based Design approach.
