Entire Vehicle Simulation in the Product Development: With BMW and Tesis Dynaware Model

摘要

BMW has developed an entire vehicle simulation model in cooperation with Tesis Dynaware to understand and improve energy flows in the vehicle. A model structure has been derived from this objective and implemented in a suitable simulation environment. The modular structure of the vehicle model makes it easy to implement subsystems with different levels of detail. Examples show the possibilities that the model offers in preliminary and series development. During the development of a new vehicle, it is an important issue to understand and optimise the behaviour of the entire vehicle as a system. The interactions in a vehicle are becoming more and more complex, with the result that it is increasingly difficult to analyse them. Under these conditions, development that is based merely on component and vehicle hardware tests would be too time-consuming and expensive. Quality and efficiency can be improved by using virtual methods. An important tool is the simulation of the entire vehicle behaviour.
