New Workflow Features

Autonomie AI

  • Available as a separate package, this version of Autonomie uses Machine Learning models trained on some of our large scale studies to provide quick Energy results.

Graphical View

  • Vehicle specific functions like Eval, Build, Debug Vehicle…. are now available directly from a toolbar in the Graphical View UI.
  • All images created in the Graphical View can now be saved to a file using a context menu on either the background or a system.

Run a Vehicle – Run Queue

  • Simulations can now be queued and launched all at once instead of running them one at a time.

Data Analysis

  • New charts are available for dataset analysis, including box charts and aggregated values.
  • Can now load dataset from Parquet files.

Autonomie Model Library Updates

  • The fuel cell system model has been updated, incorporating a thermal model. Initially, a time-delay model has been integrated to account for the impact on the electrical response of the proton exchange membrane fuel cell system. Furthermore, a more sophisticated thermal model for the fuel cell has been developed to accurately replicate the thermal dynamics of the entire fuel cell system, replacing the previous first-order differential equation used for temperature calculation. Additionally, the signal of cell voltage has been introduced to enhance fuel cell stress estimation.
  • A new test procedure for Battery Electric Vehicles (BEV), referred to as the Short Multi-Cycle Range and Energy Consumption Test Plus Steady State (SMCT+), has been integrated. This specific BEV procedure, designed for shorter testing cycles, demonstrates increased efficiency compared to the comprehensive multi-cycle testing process. Its implementation has undergone thorough validation against the test data provided by the Advanced Mobility Testing Laboratory (AMTL). The adoption of this procedure has resulted in a 17% reduction in simulation time for BEVs, with minimal deviation in estimated energy consumption (+/- 0.3%).
  • The sizing process has undergone an enhancement, introducing the capability to utilize compiled vehicles as an alternative. This enhancement presents an opportunity to achieve a 25% reduction in the time traditionally expended on adapting vehicle sizes to align with requisite performance criteria.
