I would like to know if any of you would like to discuss and learn with me the nature of controlling the Prius systems using CAN bus mods to allow optimal PHEV driving. ... pause to let shriek of PIS and PICC coders subside ..... OK, I am somewhat familiar with micro controller programming, and just got a 06 Prius and would like to PHEV it. I like doing things right, and so far have not decided on buying a system for 10 grand, or doing my own, or just using a battery charger system like the Enginer and live with it's issues. Anybody want to discuss a more open source, or open pseudo code source project to control CANbus filtering of the packets that control the ICE and the two electric motors MG1 MG2 ? We need to explore how the power split is controlled ( this allows control over how fast we let MG1 spin during high speed driving, for example ) and which messages are altered to keep the ICE off, etc. There is a forum user here , "peef" (sp?) that has apparently decoded most of this in his own PHEV system, but I'm not sure he has the inclination to share his findings here, perhaps for business reasons. Maybe start with a list of questions ? A list of known commands, and what they do ? ( there is a list I saw somewhere ) Explore what does not work, or throws error codes if tried ? I'll bet that the pseudo code to run a CAN bus PHEV is really rather simple, once you know the basic 'lay of the land'.
