4.1. Known deficiencies

• (!) Driveability-rules not ordered as defined in the latest task-force meeting.
• (!) The n_min_drive is not calculated as defined in the latest task-force meeting, along with other recent updates.
• (!) Does not discriminate between Unladen mass and Test mass.
• Clutching-points and therefore engine-speed are very preliminary.
• Results are not yet compared with the new wltp_db sample-vehicles.

4.2. TODOs

• Add cmd-line front-end.
• Add IPython front-end.
• No automatic calculation of masses and road-load coefficients from H & L vehicles.

4.3. Changelog

4.3.1. v0.0.8-alpha, 04-Aug-2014

• Documentation fixes.

4.3.2. v0.0.7-alpha, 31-Jul-2014: 1st public

• Rename project to ‘wltp’.

• Switch license from AGPL –> EUPL (the same license assumed retrospectively for older version)

• Add wltp_db files.

• Unify instances & schemas in model.py.

• Possible to Build as standalone .exe using cx_freeze.

• Preparations for PyPI/github distribution.

  • Rename project to “wltp”.
  • Prepare Sphinx documentation for http://readthedocs.org.
  • Update setup.py
  • Update project-coordinates (authors, etc)

4.3.3. v0.0.6-alpha, 5-Feb-2014

• Make it build as standalone .exe using cx_freeze.
• Possible to transplant base-gears and then apply on them driveability-rules.
• Embed Model –> Experiment to simplify client-code.
• Changes in the data-schema for facilitating conditional runs.
• More reverse-engineered comparisons with heinz’s data.

4.3.4. v0.0.5-alpha, 18-Feb-2014

• Many driveability-improvements found by trial-n-error comparing with Heinz’s.
• Changes in the data-schema for facilitating storing of tabular-data.
• Use Euro6 polynomial full_load_curve from Fontaras.
• Smooth-away INALID-GEARS.
• Make the plottings of comparisons of sample-vehicle with Heinz’results interactively report driveability-rules.
• Also report GEARS_ORIG, RPM_NORM, P_AVAIL, RPM, GEARS_ORIG, RPM_NORM results.

4.3.5. v0.0.4.alpha, 18-Jan-2014

• Starting to compare with Heinz’s data - FOUND DISCREPANCIES IMPLTYING ERROR IN BASE CALCS.
• Test-enhancements and code for comparing with older runs to track algo behavior.
• Calc ‘V_real’.
• Also report RPMS, P_REQ, DIRVEABILITY results.
• Make v_max optionally calculated from max_gear / gear_ratios.
• BUGFIX: in P_AVAIL 100% percents were mixed [0, 1] ratios!
• BUGFIX: make goodVehicle a function to avoid mutation side-effects.
• BUGFIX: add forgotten division on p_required Accel/3.6.
• BUGFIX: velocity-profile mistakenly rounded to integers!
• BUGFIX: v_max calculation based on n_rated (not 1.2 * n_rated).
• FIXME: get default_load_curve floats from Heinz-db.
• FIXME: what to to with INVALID-GEARS?

4.3.6. v0.0.3_alpha, 22-Jan-2014

• -Driveability rules not-implemented:

  • missing some conditions for rule-f.
  • no test-cases.
  • No velocity_real.
  • No preparation calculations (eg. vehicle test-mass).
  • Still unchecked for correctness of results.

• -Pending Experiment tasks:

  • FIXME: Apply rule(e) also for any initial/final gear (not just for i-1).
  • FIXME: move V–0 into own gear.
  • FIXME: move V–0 into own gear.
  • FIXME: NOVATIVE rule: “Clutching gear-2 only when Decelerating.”.
  • FIXME: What to do if no gear foudn for the combination of Power/Revs??
  • NOTE: “interpratation” of specs for Gear-2
  • NOTE: Rule(A) not needed inside x2 loop.
  • NOTE: rule(b2): Applying it only on non-flats may leave gear for less than 3sec!
  • NOTE: Rule(c) should be the last rule to run, outside x2 loop.
  • NOTE: Rule(f): What if extra conditions unsatisfied? Allow shifting for 1 sec only??
  • TODO: Construct a matrix of n_min_drive for all gears, including exceptions for gears 1 & 2.
  • TODO: Prepend row for idle-gear in N_GEARS
  • TODO: Rule(f) implement further constraints.
  • TODO: Simplify V_real calc by avoiding multiply all.

4.3.7. v0.0.2_alpha, 7-Jan-2014

• -Still unchecked for correctness of results.

4.3.8. v0.0.1, 6-Jan-2014: Alpha release

• -Unchecked for correctness.
• Runs OK.
• Project with python-packages and test-cases.
• Tidied code.
• Selects appropriate classes.
• Detects and applies downscale.
• Interpreted and implemented the nonsensical specs concerning n_min engine-revolutions for gear-2 (Annex 2-3.2, p71).
• -Not implemented yet driveability rules.
• -Does not output real_velocity yet - inly gears.

4.3.9. v0.0.0, 11-Dec-2013: Inception stage

• Mostly setup.py work, README and help.
