Quite close - real world urban driving I see between 7 and 8km/kWh. Over the
same ~20km routes, with that configuration, sumo was giving me around 7.6.
Over very short routes (~4km) sumo was giving me ~6km/kWh which is actually
realistic but I don't trust that. I don't see how the model can be simulating
the initial 'warming up' - it may be that the 'constantPowerIntake' value is
doing this - but I need to get realistic values for that base load to
understand what is happening. Certainly the equations in the original paper
don't support this.
What I did was to import my local area from osm then add a couple of routes for
which I know my consumption - as accurately as possible.
Looking at the step outputs along these routes the discharge/regeneration
values looked reasonable throughout. (numerous roundabouts/junctions/lights)
The figures I'm quoting as being representative are ( total consumption - total
regeneration ) - I don't know the real world breakdown over the specific
routes, although the vehicle reported overall averages are comparable.
I am planning to look at some longer routes but it'll take significant pruning
of an osm import to let me create them - because the netedit refresh time is
otherwise painfully slow!
Cheers
