After my recent update to 11/2019.70, I find that when driving with Active-Cruise Control in Assisted Driving mode, the "hands-off" warning (yellow lights on the steering wheel) seems to come up even when I'm firmly holding on to the steering.

Experienced this recently on a longer 5 hour country highway drive last week.

Anyone else experienced this issue, and is there any way to address or reduce the sensitivity of that feature?

Sounds like your HOD sensor could be faulty. That's not normal behaviour unless its flashing/vibrating due to a minor hazard like moving out of lane briefly? It does flash sometimes even when holding the wheel, such as to warn when about to disengage assisted driving, approaching a round-about etc.

If you are driving normally, holding the wheel and it flashes, video it and take it in for a HOD/wheel repair.

Interesting, thanks for that.

I never had this issue when I was on 11/2019.34, wondering if it could be S/W related? ...as it only started after the recent OTA update to 11/2019.70.

The point releases don't normally include functional changes. It's normally bug fixes and fixes for the upgrade process itself.

There will be a coding refresh after a change, and there are some scenarios where it could flash at you genuinely like whenever it disengages assisted driving (approaching a roundabout, junction, etc). Are you sure its not genuine warnings rather than sat on the motorway bang in the middle of the lane, holding the wheel and it then flashes?

I do find that the ACC at times requires me to hold the wheel more strongly than I prefer and/or on a part of the wheel that may not be convenient at any given moment.

I go to work each morning at 5:45 am on a turnpike with light traffic so I test this system at times. I think 25 seconds is as long as one can go before all the alarms are in great distress yet ACC will still properly manage a curve in the road.

After my update to11/2019.70 I noticed similar behavior. Driving with the ACC and the yellow steering wheel pops up. I used to just have to tap the inside of the steering wheel but this time I had to grab the steering wheel several times for it to register. I just chalked it up to a fluke. I'll try and use ACC more to see if it's a reoccurring issue.

[ifr]

Just bear in mind that later I-step uses foresight, so it will warn that assisted driving is disengaging even when you are holding the wheel.

My car doesn't require any hands on the wheel on any road at any speed but still flashes when it's about to disengage the assisted driving.

Just drove 20+ miles and didn't notice the issue pop up again. Behaved as it should.

Could you parse the second sentence if you mean while ACC is engaged which is the point of the thread?

I do find its intermittent too, some days it happens, others it doesn't.

I think there might be a number of variables at play here...

1. Its winter here, so the cold means my hands are fairly dry and cool with little moisture. Maybe the sensors need a little more moisture - possibly a conductivity issue.

2. On long drives, I tend to lower my hands to the bottom of the steering wheel, virtually in my lap, and less inclined to maintain the 10 to 2 position. Maybe the sensitivity is lower down there for the hand sensors.

3. I still think software has got something to do with it. Never had this issue until 11/2019.70. It never happened on the previous versions - 11/2019.34 and 07/2019.49 versions, so I think they still changed something....

1. Very unlikely, like you say you only noticed it after the upgrade, and it should work with 1 or 2 fingers lightly brushing against it in any conditions

2. Same. Shouldn't be an issue unless sensor element inside of the wheel is damaged, or you have a HOD control unit issue

3. Could be, but depends on the scenario when it doesn't work. You didn't answer my previous Q. Does it flash/disengage when driving normally, centre lane, no traffic, nothing happening, or is it when a hazard is detected or assisted driving cannot continue due to xyz reason?

I have had 11/2019 and subsequent i-steps and have noticed that it will disengage/flash even if it thinks there is contact, but there's usually a good reason for it. Sometimes it will warn and then recover without ever having to disengage Assisted Driving, other times you had better have hands on the wheel cos it turns off.

I'm specifically talking about Assisted Driving (ACC+SWA/LCA), and not just ACC which is what the OP stated.

The point I'm making is that my car always has hands on, at least it thinks it does, and it also complains/flashes. It's doing that not because there is a sensor issue, there cant be as its reading constant detection, it warns because it is disengaging due to XYZ reason. I've found it disengages because:
1) it hits a bump
2) coming to a roundabout and cant make it around by itself
3) obstacle detected ahead that its worried about - bollards, cones, etc
4) very steep curve it can't handle
5) wandered over the line and is correcting

That experience has changed with some of the i-step upgrades, as it gets more intelligent with (fore sight) about disengaging 'before' the incident happens and you have to take over. This is the system predicting it cant deal with something and warning, rather than just disengaging as the incident happens. Advancement in self-driving with software upgrades.

That makes a lot of sense, and might explain it.

Some of the country highway driving I was doing had some fairly narrow road sections, steep hills and narrow curves. That could possibly explain it, as I dont get this behaviour in the city/urban based Highway/Freeway driving.

Cool, I'll keep an eye on it and see what happens, many thanks for the responses

I've experienced the same thing after my update from 07/2019.59 to 03/2020.31.

It often flashes yellow and beeps when it's about to disengage. The steering wheel icon is still there in the dash with the two LED light icons on either side of the steering wheel. It's just greyed out. iDrive recovers on it's own unless you hit the brake. It really came to light to me today when I was driving on some windy roads with small round-a-bouts and sharp curves.

Same here..
After the OTA update to 11/2019.70 its all over the place. Used to be very smooth and light touch with couple of fingers was fine but now it’s more demanding.

Another thing I noticed is when I am on the Assitent hands off driving below 40mph, the car would stay at 40mph For few seconds even if the car in front is speeding well above 40

I just went from 2019/11.41 to 2019/11.70 and it does seem more sensitive to hands on the steering wheel, only drove about 45 minutes on a mix or Hwy and smaller roads but when it kept happening and now seeing this thread makes me wonder. Taking it in tomorrow and will mention this annoying change, hoping I'll get updated to 2020/07 version.

[Paladin1]

Couldn't say - my version is still 7/2019.53, and my CD tells me I don't need an update....

Its definitely more sensitive, I mean I hold the wheel quite firmly and was getting that annoying alarm.

Let me know how you go at the dealer, hopefully 07/2020.xx fixes it.

[ifr]

We sorted this.

It's by design.

It's not asking you put your hands on the wheel because it detects them not present. It's warning of a hazard that might need you to regain control.

It won't 'improve' with 07/2020, if anything it's more sensitive.

I look on this as a good thing. YMMV

I noticed he same phenomenon when I was upgraded to 07/2020.25. Maybe this is for our own safety.

It does that on 3/2020.31 as well.

Is there a way you can public or privately share the codes you used for the hands off and all roads Acc ?
