多领域车辆动力学仿真

电池驱动和混合动力驱动将是未来汽车的显著特征。 越来越多的子系统,如转向和制动系统,开始使用电力供应。这带来了新的挑战以及车辆动力学领域的机会。

Modelon为奥迪等制造商提供工具和服务,帮助他们将多体车辆动力学模型与电气和控制系统模型结合起来。

[Translate to Chinese:] Audi e-tron sports car

[Translate to Chinese:] Audi is using Modelon tools and services for testing and simulation of its e-tron sports car.

The chassis and suspension were modeled with the Vehicle Dynamics Library (VDL) and the electric power steering system was modeled using the Modelica Standard Library. The steering system controller unit was modeled in both the Modelica Standard Library and Matlab Simulink.

Dymola and Matlab Simulink have alternatively been used as simulation environments. A special focus was put on different ways to integrate these tools according to standard development processes in the automotive industry.

The representation of the vehicle in VDL enabled Audi to study the interaction between the mechanics and the power electrics in a true multi-domain manner.  Because it took advantage of the Dymola Simulink interface, the complete vehicle model could be exported to Simulink for control design.
