Cruise Control at Stop Taking Off - Dangerous

[mdecillis]

Why are you hitting the cruise button in a drive thru lane?

If you read the original post you would see that he can easily hit that big button by accident.

But again, why? I have not accidently hit any button on the steering wheel. How big are his hands? I just don’t see how you accidently hit that button while in a drive thru.

Operator error/unresponsible driving habits is what this boils down to.

I do see it’s intended to set the speed to 15 mph if you are at a stop and there is a car in front of you.

As a software engineer, allowing you to do this while you are obviously not on a road with one button press is absolutely bonkers. Its intention is for stop and go traffic. They are already differentiating between parking lots and roads with the smart speed thing. I don’t understand why they would allow that in a high pedestrian area.

I don’t however see how you can disable that one function, the stop and go part.

you cannot yet disable just the stop/go part of the assisted cruse control. If you disable the distance following element, it will default to standard cruse functionality, which means hitting that button will simply cycle the "cruse on/off" it will not then set a speed.
The system is working as intended though, so it's not technically a design flaw. It would be incredibly difficult to differentiate between someone pulling off to the drive through right next to a road or on a side road or parking lot, and being on a road with stop and go traffic.
My advice is if you find yourself hitting the button that often, disable the distance following. or use extra caution before taking your foot off the break if you really need the feature.

I can see it happening. Especially if you're wearing a big bulky jacket, that button is very easy to push and it's bigger than the others closest to where you hold the steering wheel. Accidents happen.

Just kind of an FYI. I did more testing. It’s not actually working correctly. You can even see it in the video.

When you are stopped with your foot on the brake for like 5 seconds, it’s supposed to disable the cruise control. You can see in the video, it recognizes it’s stopped, and then says hit the resume button to activate cruise control. I did not do that and the expedition took off on me.

I mean, the argument that someone has never hit a button on accident is a terrible argument. I mean people handing you things through a window, turning with gloves/coats on, kids screaming behind you. I mean if 50k of these expeditions are on the road for 10 years, just out of sheer numbers that button is going to get hit under those circumstances a lot.

Again what it is supposed to do in those circumstances is set itself, if it detects you are at a stop for X seconds it disables cruise and requires you to hit resume. This is not happening. I don’t know if it has to do with speed recognition or the lack of auto start stop on my expedition. But it’s dangerous.

I tried it on mine this past weekend. I still cannot replicate your specific situation. If it doesn’t detect a speed sign it will default to 15. If it does it defaults to that speed. As soon as I lift off break if it was less than 10 seconds or so. It does start to inch forward. Not a full throttle situation by any means.
If it detects a car or person (assuming person, in my case it wouldn’t drive forward into my forsythia) it will not move.
The truck doesn’t move after it’s stopped for a solid 7-10 seconds (I was at a light). I either have to press the gas or hit resume.
Not arguing with the button being big or ease of hitting it. But it’s just not happening to me and definitely not a situation I’ve run into that causes concern in the past 8 months.

And I was just starting to be productive today... now I need to go play with the truck for 20min

Seriously though, I hit the steering wheel buttons all the time when making big turns causing either a warning in the cluster or changing the display. They are sensitive and I could see someone grazing the cruise on button now and again.

I remember to try to set the cruise in traffic today Pressing the cruise ON sets it to 20kmh when stopped behind a car. When I release the brake it brings up the message "stopped" and then auto holds the brakes (I don't have auto hold turned on). When the car in front starts to move it shows the resume button symbol. It won't start to role on its own.

If your vehicle tries to accelerate while in cruise control with a vehicle in front of it the module is deemed compromised.

The system is working as intended though, so it's not technically a design flaw.

Just because it is operating as intended (I don't think it is) doesn't mean it isn't a design flaw. This just means it feels into the "unintended consequences" category.

I've had several things occur with the adaptive cruise control that I think are flaws. The truck sees a car stopped in another lane but can't determine it isn't in your lane and slams on the brakes. Or when a car safely crosses traffic in front of you but the truck can't determine what is really going on and slams on the brakes. These are working as intended but are poorly designed because the algorithms used can't anticipate or fully understand the whole situation.

What you are describing is not design flaw but consequences of the systems limitations. Design flaws are like the running board extended timer option that does exist and when you click it nothing happens. It’s a design flaw, it was designed to operate a set way but fails to perform its design intention.

The adaptive control not acting the way you prefer is not the same as it not operating as it is designed.
Also in the manual, it again lays out situations just like you said where the system has known limitations.

Just because it operates as designed doesn't mean that it was a good design. I think of a design flaw as something that doesn't work in an appropriate manner regardless of if it was intentionally designed that way and is just a bad design or if it was designed properly but isn't functioning properly.

Do these happen with BlueCruise engaged? I regularly have cars change lanes too closely in front of me on the freeway, @65-75mph traffic flow, and BlueCruise just adjusts for the now-shorter distance from the car in front, but never slams on the brakes or applies them too heavily.

If you look at the video I posted, it shows the stopped no then flashes hit resume but then it starts going without me hitting resume.

I don't have BlueCruise but what you describe happens with mine as well using adaptive cruise on the highway. The slamming of the brake is usually just around town when a car is turning left in front of me or when the car in front of me gets into a turn lane but I'm going straight.

I don’t have the blue cruse but I have the level below. It operates like you said. Never slams the breaks unless the person is so close you would also.
It’s usually pretty good.

@KetMalice looks I need a new phone with better resolution missed that when I watched the video.

This has happened to me 3 times, I was able to reproduce it. Sitting in line at a drive through, and driving in a parking lot. I don’t think I turned cruise control on (I did for the video to reproduce it) but it’s possible I hit the button on accident while wearing a heavy coat. Every time I’ve almost hit a car or a person because I’m at a stop and I let off the gas to move forward and the vehicle just takes off on me. This is extremely dangerous. I’m really getting tired of the issues with this vehicle.

I don’t understand how hitting cruise control at a stop, 0 mph, arbitrarily sets the cruise control speed to 15 and keeps it “active”. That’s dangerous.

I feel better now that I am not alone on this. I can reproduce this issue at will, same thing. Mine is 2022, 42k miles. Now, something that I noticed is that controls on that side are not feeling in the same way as the right side, dont know how to explain it, but they feel different when you push them. Filing a complain now, hoping any Ford representative can see this thread. Did you got any solution?
