Basically, if you're on a bike, then you are a vehicle, so this involves two vehicles, not a pedestrian and a vehicle.
If you entered the roadway first to cross (which it sounds like maybe you did since you were punched in the rear), then the other vehicle should have given the right of way to you, but if the SUV started the turn first and then you entered, then you would be at fault as they were legally in the roadway first, even coming from the other direction as when they started their turn, they were legally in the lane that you crossed. It's all a matter of timing, so basically, going on the info you've provided, it depends on who started moving into the roadway first. And as stated above, it would also depend on who was at the stop sign first who had the right of way, but since the bike path is technically not at the intersection (your drawing shows it's off by a little bit) then it would depend who started moving first
