ARTICLES Automotive Design with iQBus COMPONENT DESIGN Components can usually be designed in parallel to the topology. Another Jump Start Design (Figure 7), a power window system, was select to illustrate this process. [Figure 7] The Power Window Design contains electrical, electronic and mechanical components as well as the control algorithm either as control function in the s-domain or as software. In the virtual prototype the whole power windows system is modeled. The behavior of the mechanical parts of the window, including effects such as friction and damping, is modeled on the right side in the schematic. In the design progress the best-suited motor and motor driver can be picked and the control software can be optimized - all in the context of the complete system. With the Saber simulator the level of detail of the design can vary from a high-level control system in the s-domain down to the physical implementation with hall sensors monitoring the motor, effectively allowing the user to add as much detail as is available or required. [Figure 8] The DCPM Motor Tool is part of a suite of tools that can be used to parameterize or generate models quickly, based on information from datasheets or measurements, quickly providing required models. Modeling tools such as the DC/PM tool allow quick and easy generation of models with information from measurements or from datasheets. Models can be generated on multiple different levels; from s-domain to physical level including thermal effects.
