Simulation Tool IVIsion

Electric vehicle fleets; automated simulation processes; modular structure; comparison of concepts; calculation of driving performance and energy requirements; optimization of operational strategies; overall vehicle concept (all types)

• automated processing of large amounts of data from long-term measurements for simulations (GPS data, CAN data, passenger load)
  
• applicable for entire public transport networks
  
• algorithms specially adapted to scenarios in public transport

With IVImap, image-based maps can be

• read,
• scaled and
  
• edited.
  

The powertrain maps necessary for simulations are often not available. Therefore, IVImap already contains a large variety of maps of typical components. These maps can be adapted to the exact values of the respective application using IVImap.
