I have AP 1 on my December 2014 P85DL. In verison 8.0(2.52.22), a curve that previously had been handled well with Autosteer now is not handled nearly as well as before.
There are two curves that I take frequently that I have been using to evaluate Autosteer. One is the curve from Route 81 North to Route 481 North, and the other is the curve from 481 South to 81 South. Below is a picture of this interchange.
Autosteer's behavior on these two curves seems to change practically with every update.
I have always attempted to take these curves at 70 MPH, allowing the car to slow as necessary.
A couple of updates ago I stopped being able to use autosteer on the 81 North to 481 North curve, which is a bit downhill, as Autosteer would under steer, and if I did not take over I would have been off the road, to the left--the outside of the curve.
Yesterday, attempting to handle the 481 S to 81 S curve, which is a bit uphill, the car moved so far inside the curve that it got into the rumble strip. I took over, though it was possible I did not have to. Before my most recent update, the car handled that curve just fine.
The one big plus in this update is that I did not have the car slow down for random cars on the shoulder. In fact I passed a car stopped on the inside shoulder, while I was in the left lane doing 70 MPH, and though I was alert and expecting the car to possibly slow down, it did not. So I'd say that is an improvement.
Anyone else with AP1 seeing some regression on curves like the ones pictured above?
