S650 Mustang -Keep hands on steering wheel message

[Kitulu]

I can see that some of y'all have not read the owner's manual. The system has three settings: Alert, Aid, and Alert+Aid.

Alert: Icon turns red and steering wheel vibrates when you get too close to the lines.

Aid: Steering wheel corrects back towards the center if you get too close to the lines.

Alert+Aid: Icon flashes red, steering wheel vibrates if you get too close to the lines, and steering wheel corrects back towards center if you get way too close to the lines.

I keep the Alert setting on, and turned the Aid setting off. That gives me the "hey, you're a little close to the edge" alert without feeling like I'm fighting the steering wheel. It also takes away that pesky "keep hands on the steering wheel" message.

But the whole point of having “lane keeping” is to have it “aid” you and keep you centered, no?

My wife's Edge has "lane assist". That vibrates the steering wheel if you get too close to a line, or if you try to change lanes without using your blinker.

With "lane keeping", the entire point is to be able to allow the car to help keep you centered in the lane (which it does an amazing job doing) with your hands on the steering wheel.

I can hold the steering wheel with one hand, two hands, five hands... it still gives me the damn alert ALL THE TIME.

It's probably doing such a good job keeping the car centered that it doesn't need much input from us holding the steering wheel, so the system thinks we aren't holding it.

If I give it little nudges here and there every few seconds, it doesn't give the warning message. - but how dumb it that to have to do?

Next time I'm driving with my wife, I'm going to have her take a video.

It depends on the level of assistance that you want, or the amount of nanny-state bullshit that you are willing to put up with. One could also argue that lane-keeping assistance should not be necessary at all because when you are behind the wheel, you have one job: Drive the car.

I read the manual.
But that's not I want, I'm perfectly fine with the car helping me to maintain the lane, and it is what I want: it was working great with the S550, especially on long trips on highways, it actually helps you to drive more comfortably. It was a very useful feature (it's just my opinion). The "keep the hands on the wheel" were there also in the S550 and it worked as expected: it was warning you REALLY when you put your hands off the wheel for a certain amount of time. With the S650 it is "bugged": the warning shows every now and then, even when you're actually driving the car with both the hands firmly on the wheel, so you are "forced" to move your wheel intentionally, even on a straight road (changing your trajectory), or you must turn off the aid, which means negating this feature, if you don't want that annoying message and sound every 15 seconds.
Got it?
IMO the system must be tuned properly (fixed by Ford), it cannot relay on the wheel rotation, it doesn't make sense: if the road is straight and the car is going straight already, why the hell I must go left and right like a drunk driver?

But how will I text and look at my phone??

No, the system (the aid) is there: if it's there, it's supposed to work properly (no matter the personal preferences), if it's "bugged", it must be fixed. Coz the issue here isn't that the aid doesn't work properly (it was already in the S550), but just that the "check of your hands on the wheel" isn't working properly.

This. 100%.

On mine, it's the same; the warning is quite present, so I deactivate it every time I start up.
It's not a pressure-sensitive sensor, but you do have to move the steering wheel 1° every 15 seconds, and on freeways at high speed, it's not very good.
Otherwise, without this warning, it works fine. Too bad.

There is one issue about the 10-2 hold no one talks about. If you have your hands on the steering wheel's 10-2 position, and the airbag explodes, you're going to break your wrists arms or both, or at least wished you did!

Why? Do you not think airbag design takes the driver position into account?

 

[Alan Applegate]

No. Most (driver's airbag) inflate like a donut and are about 32 to 35 inches in diameter. There are no 'cutouts' for your arms. What occurs depends a lot on how good your grip is, when your brain tenses up your muscles due to impending doom as it were. Few drivers actually relax and let things happen. There is a good example of not doing this.

If some idiot runs a red light or perhaps passes on a two lane road either instance impeding your line of travel, the instinct is to steer clear in an effort to avoid a collision. That is true of most drivers (good and bad). As a result they both steer into a collision. If the smarter driver would have continued straight ahead, there wouldn't be a major collision. There's glaring truth in this in a myriad of YouTube videos.

Yes, but you have to hold the steering wheel somewhere. Injuries to the arms are rarely life threatening unlike those to the skull. Collar bone fractures are also a risk from the seatbelt but less so in modern cars with load limiting belts.

Plus the airbag type and deployment matters, they are often bigger in the US than Europe as seatbelt wearing mandated here means a smaller bag is effective. The bag is smaller because it is assumed the driver is wearing a seatbelt. Dual stage bags etc etc.

No need for Youtube videos - just use actual research papers for your answer

Upper extremity injuries related to airbag deployments - PubMed

An under-hand steering wheel grasp produces significant injury risk to the upper extremity during airbag deployment - PubMed

The second paper suggests '10 to 2' is less at risk of fractures than other positions

10 & 2 is ‘old school’, ‘new school’ is 4 & 8

 

[npole]

old.. new.. the only correct position is 3-9.

He's the Ford WorkShop Manual description of the Hands Off Warning ...

Hands-Off Warning
When the lane keeping aid is active, the PSCM continuously monitors the torque sensor in the EPAS system to determine if
a hand is on the steering wheel and sends the data to the IPMA.

If the IPMA detects that the driver's hands are off the wheel
for more than a few seconds, the hands-off warning is generated.

The hands-off warning is generated in 2 levels. The first level is a message center warning only and is triggered after 3
seconds of hands-off driving is detected and a lane keeping aid intervention occurs.

The second level warning consists of a
message center warning and an audio chime and is generated after 6 seconds of hands-off driving.

NOTE: Due to certain road conditions and the driver's individual grip/touch on the steering wheel, the system may
generate a hands-off warning when hand(s) are still on the steering wheel.

WorkShop Manual also sez,

The IPMA is an internal component of the Advanced Driver Assistance Systems (ADAS) module.
Provides the PSCM with the necessary information for lane centering. Such as driver hands off the wheel, lane centering system status,

IPMA camera alignment is required for the lane keeping alert and lane keeping aid to function correctly. The procedure is
initiated using the diagnostic scan tool and requires about 10 minutes of driving above 64 km/h (40 mph) on a flat, straight
road with highly visible lane markings to complete.



I'd perform the IPMA Camera alignment see if that helps.

I agree with alert levels 2 and 3, but the presence of hands is not necessary. You just need to make a small 1° steering movement to deactivate the alert, which will reappear 15 seconds later.
