| Abstract |
The examination of power trains in vehicles requires special techniques for the modelling of different electrical/electromagnetic components and electronics. System considerations of automobile power trains result in the need for mixed technology, mixed mode simulation at a high abstraction level. At the same time high accuracy is required to gain significant results. To reach these contrary goals, qualified evaluation of components' physics is necessary as well as a suitable generation of behavioural models on system levels. Beside usual electronic systems, electrical drives and actuators, modern cars show highly non-linear and dynamic components such as electrical valve trains, integrated starter generators and electrical machines for hybrid and E-car applications. In addition new energy storage concepts and components as well as main and auxiliary networks have to be considered. Here many types of phisical effects have to be regarded, which are static, stationary or dynamic in nature. Power, energy and torque related parameters have to be evaluated. The way to transfer physical behaviour to simplified component models, well suited for system level simulation is shown. System level simulations gives the opportunity to detect exceptional status of the system and to perform extensive tests within the simulation of complete cars of any type as conventional, hybrid and electrical cars. |
