To be clear it's not looking for just hands on the wheel, it's looking for torque. Either an occasional jiggle or a constant weight, like one hand holding at 9 or 3 pulling it down slightly.
Yeah, but if weight of two hands on the wheel is not enough, I don't know what is?
Well, if you have two hands on the wheel instead of one, are you applying torque? It's not a weight sensor either
I guess the question is how much torque is enough torque.. Or are you saying weight of hands on the wheel adds no "torque" on the wheel? My experience is that one hand on the wheel usually works, two hands on the wheel works more often.. but still I get alerted every once in a while. Am I supposed to set a mental timer to actively pull on one side every few seconds?
if mine gives me the warning, the very slightest jiggle of the steering wheel clears the alert. like super tiny. all it needs is your motion to do something very slightly different than it's doing to know you have control. I suppose if you have two hands on and are touching it so slightly that you don't give it any input, it won't know you are holding the wheel. it's drive assist, so your natural action of holding the wheel while it assists you should give it just the tiny bit of jiggle needed. it'll usually turn the wheel just a little in a way different than you would and so your hand doesn't quite have the exact same steering input and as such, you'll apply a little force on the wheel as it's doing what it does and that should be enough.
I'm saying two hands on the wheel could add less torque than one hand, because your left hand torque is cancelling out your right hand torque. Torque means rotational, not downwards force. Personally, I hardly ever get the warning if I just let either arm dangle from one side of the wheel. I don't know how to quantify the amount of torque in text other than to say it's slightly more than nothing and slightly less than enough to override auto-steer. At least in my car that's a decently wide margin.
It does not.
Both other cars I've had with a variant of lane centering (2017 Acura MDX and 2024 BMW X7) were happy about resting a hand on steering wheel. X7, of course, has hands-free on freeways up to 85mph, but requires hands on the wheel for country roads/highways. Both cars were very reliable about detecting hands on the wheel, even though MDX lane centering wasn't all that great when it came to sharp curves. I would have taken MDX' lane centering over Lucid's until this most recent update, but now it is far better. Wish I didn't have to do this "periodic pull" business, and just rest my hands on the wheel.. oh well.
hopefully it's a transition period to hands-free, especially since it has the eye sensor. we'll see, I'm sure it will be a while.
Not very much. Not that mine should be the example, but I can avoid the constant warning by putting just my left thumb on the bottom of wheel and just applying enough pressure and torque on long straight line drives on freeways.
and they like to hide under the cars and close to the wheels
