Engine control analysis
Mahle Powertrain's Integrated Data Acquisition and Analysis service uses proprietary software to generate robustness metrics for powertrain controller software and calibrations. High-resolution real-world customer usage data are recorded and post-processed with custom analysis routines, allowing transient and intermittent faults to be captured and related to instantaneous vehicle usage conditions. Trend analysis methods allow product development engineers to understand how systems behave over the operational life of the vehicle. This is particularly useful for onboard diagnostics monitors and adaptive parameters. Customer usage profiling ensures that durability and sign-off testing can be tailored to match conditions seen in the field. Graphical data presentation methods of key data points allow engineers and managers to determine system behavior quickly. The system has provided early detection of potential recall issues for various automotive OEMs.
