Crash avoidance

[Cherokee]

I fell in behind a motorcyclist this week.
Now stay with me people’s, I’ve been behind all kinds of motor cycles. And what happened has never happened behind any Harley’s, sport bikes etc.
This bike was a little 250 trail bike with a skinny rider. His back pack , the bike, his helmet and clothes were all green.
Olive drab actually.
The overall profile of this bike and rider was a shape just like a pedestrian, his tail light was Not illuminated at all.
He slowed and I eased into the zone where automatic braking and an alarm sounds. Never a problem it just quickly, smoothly backs me off.

My question to you internet wizards is why did the system go to full braking at the antilock threshold?
I mean my Maverick tried to do a hand stand,
I shit you not !

My question, did it, the A. I. think that biker was a pedestrian right in front of me ?

The guy behind me didn’t hit me partially because the first thing I did was foot on the brakes to light up my brake lights.

60 down to 35 mph at the antilock threshold was wild. I bet less than one percent of the Maverick drivers out there take a moment to practice this level of braking. I did and glad of it.

IMHO upgrading the Mavrick with Brembros or some other more power brake is an absolute mistake.

I know all my mini trucks limits but still I’ll likely never turn that feature on again.

Penny for your thoughts ?

I immediately turned the system OFF.

Whu~Tu~Fufu~FaFa factor happened ???

Being both a biker and Maverick driver, I find that a bit unnerving.

All olive drab??? Not the sort of thing I've encountered from the multitude of bikers I've shared the road with (I've made many trips before, during, and after Sturgis.). Seems like a recipe for disaster.

Anti lock doesn't stop as fast as lock-up, just allows more control while breaking. My buddy, who races drove my car this weekend and we'd constantly got the warning as he is always ON one pedal or the other (which is what you're taught racing). I don't think the size of what's in front of you matters to the Mav, but probably does to your perception. Most riders injured or killed by others is due to the other vehicle driver not perceiving the motorcycle. If you go to Asia where small motorcycles outnumber cars, you'll see car/truck drivers much more aware of motorcycles because their brains are trained to take note of them.

All my life I’ve been told by all kinds of sources that the controlled braking of anti lock out stops any vehicle at full lock up under all conditions.
The very few times I’ve used anti lock I felt that I stopped in a much shorter distance wet or dry.

in wet or snow, very likely, regular pavement-not so much

I think you are right - perhaps due to color or small nature of the object it saw - thought it was not moving, for the split second decision it made.

And ya, when it decides to brake for you it's a full stop, unlike the ACC, or Pre-collision assist that AEB is final step of.

WHAT IS AUTOMATIC EMERGENCY BRAKING
Automatic emergency braking may activate if the system determines that a collision is imminent. The system may help to reduce impact damage or completely avoid the crash.


HOW DOES PRE-COLLISION ASSIST WORK
The system warns the driver of potential hazards by providing three levels of assistance.

If your vehicle is rapidly approaching potential hazards, the system provides the following levels of functionality:

1. Alert.

1. Brake Support.

1. Automatic Emergency Braking.

Alert: When active, a flashing visual warning appears and an audible warning tone sounds.
Brake Support: The system is designed to help reduce the impact speed by preparing the brakes for rapid braking. The system does not automatically apply the brakes. If you press the brake pedal, the system could apply additional braking up to maximum braking force, even if you lightly press the brake pedal.
Automatic Emergency Braking: This may activate if the system determines that a collision is imminent.
Note: If you perceive the pre-collision assist alerts as being too frequent or disturbing, then you can reduce the alert sensitivity. Setting the low sensitivity would result in fewer and later warnings of a potential forward collision. The manufacturer recommends using the high sensitivity setting where possible.
Note: Automatic emergency braking performance is not affected by the sensitivity setting.
Each system has various levels of detection capabilities. See Pre-Collision Assist Limitations.

I was also told the biggest problem is the drivers. To correctly use anti lock you push and hold that brake pedal all the way down.
Most drivers lift a little during the process and that disables the anti lock and increases the stopping distance.

...The guy behind me didn’t hit me partially because the first thing I did was foot on the brakes to light up my brake lights....

..could apply additional braking up to maximum braking force, even if you lightly press the brake pedal...


I think these 2 things combined.

You are correct. Anti-lock will stop you quicker (and under control) than full lock up. Once the skidding starts you lose much of your braking ability as the tires skid. Sure was fun all that skidding around though back in the day! ABS also works way better in snow, but the fun is taken away. On ice the situation becomes one of the following though: SNAFU, FUBAR, TARFU!! ABS on ice is till better than not having it, but how much better, I don't know. Taught the kids and grandkids snow/ice driving in parking lots after normal hours. They had a ball.

 

[Cherokee]

Yeah the slip and slide pump the brakes game was the way I learned.
Tons of fun !

I know nothing about the engineering of how the collision avoidance system is programmed so take my thoughts with a grain of salt.

Could it be that the bike in front of you was not the issue but the car in front of the bike? Between the bike and the next vehicle, your Mav interpreted those objects differently than what was actually there. Especially if their speeds were not similar.

Like your truck saw the bike as a post standing still. I dunno.
