How to simultaneously use flexible driveshafts and custom models for Powertrain components ?

Question

While integrating customized models for individual powertrain components (like Gearbox, Motor, etc.) as Simulink Plugins, it is not possible to simultaneously use flexible driveshafts.

An error 'Using flexshaft is not allowed' is shown.

Solution

What is the reason for this?

  • Simulating the flexible driveshafts / flexible driveline models in CarMaker requires dynamic oversampling for numerical reasons
  • Simulink plugins do not fulfill this dynamic oversampling requirement


How to overcome this?

  • The custom powertrain components can be integrated as FMU Plugins or as C-code models
  • Both these approaches support dynamic oversampling and therefore allow simultaneously using flexible driveshafts
