Using ABRP as in car nav

Recommended Posts

Hello All

As the EV route planning in MEB platform cars is still catastrophic and because it is not possible to run the planning in ABRP over Android Auto and the in car nav at the same time, currently the best solution for a sophisticated planning is to use ABRP also as the real time navigation with Android Auto.

I used that meanwhile for around 2000km navigation around Germany. Here is what I would like to bring up for discussion:

1. The "lookahead heading estimation" (https://abrp.upvoty.com/b/report-a-bug/bugs-bugs-bugs/) is confusing. Especially in inner cities with complex junctions, you loosing orientation to easy. MEB internal nav and also Google Maps are not doing it and are more easy to follow because of this.

2. I would like to see the opportunity to switch through all the modes at every given time, not "The other two modes only show the full overview, if no close by instruction is shown." Especially with the next items I will mention, it's hard to keep the overview on the route planning as it is far more dynamic due to traffic situation, charging planning including availability of chargers, than a "normal" ICE routing.

3. The routing algorithm is sometimes...surprising. I don't know which one you are using, but I think it's not on the level like Google maps or other up to date navigation systems. 

a) Short before a planned charging stop the navigation decides to leave the autobahn one exit before originally planned and showed. 


It could be because of traffic or because the navigation thinks, it's the shorter route. Right after entering the exit ramp, it routes back to the autobahn again, so I turned around again, no traffic, no other reason. Maybe some threshold for saving time is set odd or something like that.

On the exit ramp I wanted also to switch to the overview mode to understand what the nav is doing. See point 2, I cannot do it at that time.

b) I also encountered this behaviour with a planning this morning:

ABRP:                                                                              Google Maps:

Its an +800km route to italy. In Germany today is a public holiday. No traffic issues. Google Maps just continues on the autobahn. No charging stop to be reached on this part of the route, so why?

c) And there are some other opportunities like that, which I could not document. 

There is also an option of "alternative routing calculation" in the navigation settings. With this, the routes I checked are even worse. Also using more a shorter route than the obvious fastest route. That all remembers me a little bit when we started with Navigon Navigator 5 on our IPAQ 2110 PDAs back in the days, where you can influence the routing by changing the speed settings in an *.ini file. This sometimes leads to such a behaviour.

It would be nice, if I can get some reports on this topics from some other users before I request changes.
