Hybrid Assistant is now available

Development on Torque Log Analyzer has been paused since I was working on Hybrid Assistant.
Now Hybrid Assistant has reached Beta and is available to those who wants to test it.
Check the Hybrid Assistant site.

ICE Efficiency

Thanks to slowmark from Hybrid Synergy Forum, I introduced the ICE Efficiency measurement: it's an indication of how much efficiently you are burning your fuel.
Basically it's power divided by consumption (Actual Engine Torque * RPM / FuelFlow), scaled from 0 to 100.

There are 2 Efficiency charts:

  • Percent Efficiency measure efficiency relative to the maximum observed value in the whole trip. It's charted alongside RPMs and SOC for easy analysis.
    It can't be directly compared between different trips or cars
  • Absolute Efficiency reports efficiency value unscaled.
    This may be used to compare different trips from the same car.

Comparing efficiency between different cars may be done with caution:
  • on Toyota HSD cars, "Actual Engine Torque (Nm)" is a custom PID collected by ECU, and thus may be considered an accurate value, as much as RPM and FuelFlow.
  • on generic cars, "Actual engine % torque(%)", a generic Torque PID is used. This value is a percentual value, and it can't be directly compared with values collected from HSD PIDs

So comparing absolute Efficiency values from two different HSD cars makes sense, while comparing to non-hybrid cars does not.

Note as lower RPM may lead to higher efficiency.
