Calculation error with ferry routes

Recommended Posts

Description: When a route includes a ferry connection, ABRP uses the distance of the ferry route as part of the range calculation.  This can result in routes not being found for short range vehicles.
Replication Steps:
  1. See the link as shown above.  Note it includes an 8 km land route, a 436 km ferry route then another 8 km land route.  Vehicle used is a Tesla Model S 2012-2018 85D.  The route plans correctly.
  2. Change the vehicle from an 85D to a 75D.  The route does not plan correctly - no routes found. 
This route should be able to be calculated even with (e.g.) a Nissan Leaf 24kWh.
Note that vehicle SOC calculations are correct.  The distance is "cancelled out" with the next step (distance is shown as "-428 km") so the total trip distance is correct.

Update - I notice that the distance is displayed correctly now - 8 km, 436 km, 8 km (rather than 8 km, 436 km, -428 km).  I'm not sure if something was updated, or if I did something different on my end.  Everything else is the same though!

More information that may be helpful - see this route: https://abetterrouteplanner.com/?plan_uuid=83140118-fd1f-4a4f-924d-1820eb020e28

(Launceston, Tas, to Richmond, Vic) - basically the same as before but with another ~100 km of driving first.

Note that the routing engine is happy for the route to be completed with an 85D boarding the ferry with 65% (despite this giving it less remaining range than a 75D at 100%, which fails - in both this example and the previous example).

I'm not sure what this means but it might help to work out what the issue is!

Any updates on this issue from the ABRP team?  It seems to be a general issue that applies to any ferry route.

I just tested it again, from Melbourne to Devonport, in case anything had changed.  Same issue.  A Model 3 MR can do this with 90% remaining.  An SR+ can do it, with 83% remaining.   But change it to an SR and it fails.
