Hello to all.
I thought I. was being careful in ordering my new 2022 F250 Lariet, but between my lack of knowledge and the sales staff's, ended up without some features including adaptive cruise and lane control. Most importantly the collision avoidance relies on only a front camera and does not have radar. .Has anyone had experience with this more limited form of forward collision warning. I ask because in 500 miles of driving and testing I can't find an indication it is functioning after turning it on. Dealership is a month out on service. Looking for information on at what distance I could expect some warning. Tried placing some large inflatable toys on roadway, but no reaction from system...drove right over them. . Thanks for your thoughts. .

 

I get a flashing COLLISION AVOIDANCE and a lot of attention-noise when I don't slow down for vehicles turning out of my lane when I get too close and hadn't touched the brake pedal. I've only gotten it a couple times, but that is when I drive like the maniac that I am.

 

Are you saying it doesn't use the same radar the adaptive cruise control uses?

 

I have a 2021 escape for work. It does not have adapted cruse. It has a camera behind the rear view mirror for collision mitigation and lane departure.

 

Adaptive cruise uses radar, if you have only standard cruise then you have no radar and the forward collision warning system is dependent on camera alone. Not sure what limitations are on camera system alone and dealership doesn’t seem to know.

 

You have to drive fairly aggressively to get the collision avoidance alarm to go off. Like if somebody is slowing down to turn right and you don't slow down soon enough and are coming at them fast like you are going to rear end them, it will go off. Mine has went off a couple of times when the person turning slows down way more than I anticipated and I have to quickly move into the left lane to avoid them.

 

There is a big difference in the two systems. I had a 17' Platinum with adaptive cruise and the collision warning (audible and red light on windshield) would go off all the time. There is a bend in the road in my development and someone parks on that bend (not the smartest person) and with my 17' it would always go off when I passed that vehicle parked on the bend. Fast forward to my 21' Lariat without adaptive cruise. When I drive past that same vehicle, parked in the same spot, nothing happens. As knaffie mentioned you have to be on the go pedal and closing in somewhat fast on the person in front of you breaking for the audible and warning light on the cluster to go off. I initially took my 21' back to the dealer when I first got it thinking the system wasn't working because of how much my 17' would go off. Strangely enough, after I had the windshield recall done on my 21' it seems to go off a little more now but still nothing like my 17' with adaptive cruise. I wasn't a fan of the adaptive cruise because it seemed to be chewing through my brakes when using it all the time, but had I known they remove the bumper radar for the collision system I would I would have added it to my 21' just for the better forward collision warning protection.

 

Pay attention to what your doing. I don’t like nor agree with all this new age adaptive crap basically puts you in a comfort zone that you don’t need to pay attention your car is for you. Bull**** its a computer and if you put you and your family lives in its hands you got issues. Sorry I might sound like a *** but dam people pay attention to what your supposed to be doing driving and you will ne good.

 

Agree 100%, but we're all human and everyone one of us looks down at the radio, HVAC controls, or something at some point and it's nice to have an "added" level of help if/when needed. I think I used that feature once while I had my 17' and having the system preload (or whatever it does with the brakes) made a world of difference and I was surprised how quickly the truck came to a stop when I hit the brakes. Drives me crazy to hear and see these stories about people getting into accidents when letting auto pilot or some other feature drive for them. I can tell you that I will not let a car drive for me in my lifetime. I like being in control, no one to blame but me for anything that happens.

 

Settle down man. It's a collision avoidance system that applies the brakes before you smash into something, not a full self-driving car. It's a tool to help further protect your family's lives during unforeseen circumstances that may happen even when you are paying attention. The same goes for ABS brakes, air bags, seat belts, and backup cameras. Nobody needs these things, but they could be helpful in avoiding injuries. I can't imagine that anybody would purposely not apply the brakes themselves expecting that the truck is going to brake for them before they rear end somebody because that's not the intent of this system. We can agree there is no replacement for being a good driver, but that doesn't mean all electronics that help the driver are bad.

 

Well said. My thoughts exactly. Computer controlled systems also have a faster reaction time then humans too.

 

Let me take a stab at this...The items that you refer to don't actually take control of the vehicle, most are engaged when the driver initiates them. The fear of a malfunction is in the back of a lot of peoples' minds, hence the hesitancy to adopt

 

i have regular cruise in my 21
the emergency brake collision avoidance in my truck has gone off once and slowed the truck. i was coming up to a bend in the road and the oncoming truck was higher than me but in what the truck perceived as in my lane, as its a weird bend. the truck gave me a loud alert in the IP and slowed down, then went back to normal as soon as it started once the other truck came fully around bend in their lane

i had no idea it was in my truck. caught me off guard

 

So . . the non-adaptive cruise will apply the brakes at some point? I know mine has only gone off once; as a car was making a right turn in front of me. No brakes were applied. And it was so darn close by the time it went off that I don't think I could have stopped in time if the car had not been clearing the lane.

 

This from the '22 Owner's Manual.....

Pre-Collision Assist:
WARNING: In situations where the vehicle camera has limited detection capability, this may reduce system performance. These situations include but are not limited to direct or low sunlight, vehicles at night without tail lights, unconventional vehicle types, pedestrians with complex backgrounds, running pedestrians, partly obscured pedestrians, or pedestrians that the system cannot distinguish from a group. Failure to take care may result in the loss of control of your vehicle, serious personal injury or death.
PRE-COLLISION ASSIST LIMITATIONS
Pre-collision assist depends on the detection ability of its camera and sensors. Any obstructions or damage to these areas can limit detection or prevent the system from functioning.
and then there is this:
Note: Brake support and automatic emergency braking are active at speeds up to 80 mph (130 km/h). If your vehicle has a radar sensor included with adaptive cruise control, then brake support and automatic emergency braking are active up to the maximum speed of the vehicle.So it seems the camera is involved. That probably explains why you can get a failure notice when starting up and a super dirty windshield. There are notes about this all through the section in the owner's manual about pre collision assist.

I wasn't sure the camera was involved. But it seems the camera is the primary sensor with the adaptive cruise radar system as a secondary system. There are explanations, notes, and warnings throughout the section on pre collision assist - including warning after warning about being responsible.
