Low speed automatic braking

[Black Denali Canada]

Hey Everyone !!

 

I have been searching and searching and found nothing. (I am sure it is my poor skills so I apologize in advance)

 

In my 2017 GMC Denali it lists low speed automatic braking as a feature but really doesn't explain the limitations.

 

At what speed will this system completely avoid running into the vehicle ahead of you? Or is this basically for in a parking lot if you are moving it will stop you from running into another vehicle?

 

If anyone knows more about this it would help me a lot!

Try it out in a parking lot and report back

See around page 306 in your owner's manual........

Got me curious, so I looked it up.

 

From page 295 in the 2017 sierra/denali online manual:

 

Forward Automatic Braking (FAB)

If the vehicle has Forward Collision Alert (FCA), it also has FAB, which includes Intelligent Brake Assist (IBA).

When the system detects a vehicle ahead in your path that is traveling in the same direction that you may be about to crash into, it can provide a boost to braking or automatically brake the vehicle. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation, the vehicle may automatically brake moderately or hard. This forward automatic braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See Forward Collision Alert (FCA)System 0 293.

The system works when driving in a forward gear between 8 km/h (5 mph) and 80 km/h (37 mph).

It can detect vehicles up to approximately 60 m (197 ft).

{Warning

FAB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on FAB to brake the

vehicle. FAB will not brake outside of its operating speed range and only responds to detected vehicles.

FAB may not:

. Detect a vehicle ahead on winding or hilly roads.

. Detect all vehicles, especially vehicles with a trailer, tractors, muddy vehicles, etc.

. Detect a vehicle when weather limits visibility, such as in fog, rain, or snow.

. Detect a vehicle ahead if it is partially blocked by pedestrians or other objects.

Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes.

FAB may slow the vehicle to a complete stop to try to avoid a potential crash. If this happens, FAB may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB or firmly press the accelerator pedal.

{Warning

FAB may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. To override FAB, firmly press the accelerator pedal, if it is safe to do so.

 

Intelligent Brake Assist (IBA)

IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead.

Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released.

{Warning

IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs, take your foot off the brake pedal and then apply the brakes as needed. FAB and IBA can be disabled through vehicle personalization. See the “Auto Collision Preparation” information in “Collision/Detection Systems” under Vehicle Personalization 0 155.

{Warning

Using FAB or IBA while towing a trailer could cause you to lose control of the vehicle and crash.

Turn the system to Alert or Off when towing a trailer.

Mine does it at highway speeds even.... Right after the red light flashes in my eyes it will brake for me (out of cruise control). edit: I feel like I should preemptively caveat this... the car was changing lanes and I had space to pass but my system still thought I was going to hit them apparently. I was probably doing 75-80mph.

 

I am not sure if that feature is what it is referring to or it is more like the crash avoidancde systems in MB that put you into a full out brake when it 1. senses slowed/stopped traffic ahead of you and you 2. touch the brakes at all.
