Data Analytics: Focus on the essentials

MXeval Desktop

MXeval is designed for a high sophisticated objective evaluation of vehicle attributes. A very fast and easy transfer of measurement or simulation data into Key Performance Indicators enables to manage complex tasks. A high degree of automation and standardization guarantees fast and always comparable results. It also allows easy validation of simulation vs. road test.

Target Management: Always your goals in mind

MXeval Barplot

For each KPI, assessment boundaries can be specified to configure a unique target behavior.

This assessment configurations apply color indicators to all numeric results which gives an instant feedback about the quality of the evaluation results.

Automation: More time for your creativity

MXeval is designed to give you the choice: In addition to a manual file input you can also start the fully automated observer mode. It monitors a specified folder and evaluates new files autonomously.

This way the automation is independent from your simulation, measurement or test environment.

Online Mode: See tomorrow’s results today

Control is good. Early control is much better. MXeval offers different modes depending on the use case. In online mode the GUI is optimized for smaller (touch) screens and in-vehicle use. This makes it even easier to evaluate the results directly after a maneuver, especially for vehicle testing and calibration tasks. The combination of online and observer mode produces fully automated results even before you turn your head to the screen. In-vehicle evaluation prevents unpleasant surprises and therefore additional test days due to incorrect measurements – job is done!

Customizable: This is what engineers dream of

MXeval is highly customizable for all kind of applications, which allows you to integrate it seamlessly into any workflow.

  • Tests: Implement custom test cases to cover the entire validation/evaluation range
  • KPIs: Calculate additional KPIs in each test evaluation
  • Plots: Create additional output plots to analyse specific data more closely
  • Correlation: Create scatter plots to analyze the correlation between different KPIs
  • Channels: Integrate additional channels for a customized evaluation
  • KPI Target Definition: Receive an instant feedback about the result quality
  • KPI Namespace: Rename names & units to fit to your standard
  • Summary Functions: Perform statistical analysis over all evaluation results

Reporting: Let the facts speak and make right decisions

To measure success in the company, results have to be reported, which is usually an inefficient and not standardized process. With the automated reporting in MXeval Generator, the workload is significantly reduced and decisions cab be made based on hard facts.

The html-based report provides an interactive, responsive and cross-platform use.

Compatibility: “Click and go” makes it easy

Since MXeval is developed with MATLAB, there are almost no limitations in terms of the input file format. However, MXeval natively supports 4 widely used file formats that can be used without further pre-processing of the data.
