Autopilot nagging intervals

[lunitiks]

I always thought that they were completely random, but today I found that they occur at exactly 800 metres (≈ 0.5 miles) when driving at 63 km/h (speed limit +3), under these conditions:

• AP1 @ 2017.28 c528869
• Country road
• No lead car

I logged 0,8 km no less than twelve (12) times in a row. I did it by resetting the trip meter every time the nagging occured.

Unfortunately I didn't get a chance to log the intervals at other speeds...

Please contribute to this thread with more data!

BTW @verygreen have you by any chance seen any SW-code on this subject?

Altogether now:

"Country roads, take me home (*please place hands on the wheel*) to the place I belong.
West Virginia, mountain mamma, take me home, (*please place hands on the wheel*) country roads."

AP1 or AP2?

I would never use AP on "country roads". Maybe AP is indicating you should simply take over.

AP1. By "country road" I meant an undivided two-lane road (traffic in each line moving in opposite directions) in rural, open landscape. Good lane markings. Similar to what @DÆrik is driving from 0:45 in this vid:

I went for another drive, this time I clocked the nag intervals.

47 seconds. Every time. No exception, even when going through different speed limits. I did drive above the speed limit shown in the IC all the time (+3 or +5 km/h).

However: In a tunnel with SL 80 km/h, I tried to go 70 km/h (10 below), and the nagging stopped. No nags in like 2 minutes before I had to manuever a roundabout.

Preliminary theory: Nag interval ≈ 47 seconds when driving above speed limit. Longer intervals when going below.
