dispSignalSummary

Display powertrain subsystem energy analysis

Description

example

The dispSignalSummary(SubSystem) method displays the subsystem energy for the autoblks.pwr.PlantInfo object. Use the autoblks.pwr.PlantInfo object to evaluate and report power an energy for component-level blocks and system-level models.

After you use the findChildSys method to retrieve the autoblks.pwr.PlantInfo object for the subsystem that you want to analyze, use the dispSignalSummary(SubSystem) method to display the results.

Analyze the power and energy in the conventional vehicle reference application. To use the dispSignalSummary method to display the engine and drivetrain subsystem results, see step 6 and step 7.

  1. Open the conventional vehicle reference application. By default, the application has a mapped 1.5 L spark-ignition (SI) engine and a dual clutch transmission. Project files open in a writable location.

  2. Set the system name to SiCiPtReferenceApplication.

    Create the autoblks.pwr.PlantInfo object.

    Use the PwrUnits and EnrgyUnits properties to specify the units.

    SysName = 'SiCiPtReferenceApplication';
    VehPwrAnalysis = autoblks.pwr.PlantInfo(SysName);
    VehPwrAnalysis.PwrUnits = 'kW';
    VehPwrAnalysis.EnrgyUnits = 'MJ';
  3. Use the run method to turn on logging, run simulation, and add logged data to the object.

    run(VehPwrAnalysis);
  4. Use the dispSysSummary method to display the results.

    dispSysSummary(VehPwrAnalysis);
  5. Use the xlsSysSummary method to write the results to a spreadsheet.

    xlsSysSummary(VehPwrAnalysis,'EnergySummary.xlsx');
  6. Use the findChildSys method to retrieve the autoblks.pwr.PlantInfo object for the Engine subsystem.

    To display the results, use the dispSignalSummary method.

    Use the histogramEff method to display a histogram of the time spent at each engine plant efficiency.

    EngSysName = 'SiCiPtReferenceApplication/Passenger Car/Engine';
    EngPwrAnalysis = findChildSys(VehPwrAnalysis,EngSysName);
    dispSignalSummary(EngPwrAnalysis);
    histogramEff(EngPwrAnalysis);
  7. Use the findChildSys method to retrieve the autoblks.pwr.PlantInfo object for the Drivetrain subsystem.

    To display the results, use the dispSignalSummary method.

    DrvtrnSysName = 'SiCiPtReferenceApplication/Passenger Car/Drivetrain';
    DrvtrnPwrAnalysis = findChildSys(VehPwrAnalysis,DrvtrnSysName);
    dispSignalSummary(DrvtrnPwrAnalysis);
  8. To plot the results, use the sdiSummary method.

    sdiSummary(VehPwrAnalysis,{EngSysName,DrvtrnSysName})
