My guess, if you have any sort of lane departure warning system, you'll get the wheel rumble or other warning if you start to deviate from your lane without signalling.

Re: Im in love with the ACC

What I wondered was when ACC brakes, do the brake lights go on? I've followed cars in very "speed up slow down" traffic patterns before. While I was extremely confident ACC could handle this, I wasn't so sure about the drivers behind me if my brake lights weren't being used by the ACC if that makes sense.

Re: Im in love with the ACC

ACC illuminates the brake lights if braking, but not when simply decelerating. Same as when you're doing it.

The gap for each distance setting is varied by speed. Aside from when towing or when the asphalt is wet, I tend to use the closest setting. I reckon there could be another step closer without freaking anyone out.

Cheers,
Steve

Since you don't have ACC, I can understand you not fully understanding how it works.

1. Vehicles with ACC do not tailgate. They maintain the distance set by the driver. That distance usually isn't shorter then what drivers without ACC maintain. In fact, it is often wider to account for possible electronic mishaps.

2. Drivers using ACC do not have to hit their brakes when traffic slows. Nor does the ACC system always apply the brakes to slow down. It also reduces engine power to slow (just like a human driver does). And while it might not be able to anticipate driving patterns as well as a human being, it does pretty good.

3. Any drivers that react by braking just because they see a vehicle ahead hit their brakes is NOT PAYING ENOUGH ATTENTION to the road & the conditions around them. Seeing a vehicle ahead hit its brakes should be noticed, but you should also notice if it is slowing suddenly (hard braking) or just using their brakes to maintain distance.


Oh... and exactly HOW would you know whether a vehicle has a system similar to ACC, or if the driver is actually using it?!?


Couldn't Agree more! The system is quite good at setting and maintaining safe distances. I don't so much think they are for failure as much as they are appropriate for the conditions. The distance increase with speed as they should and are quite far. Most people drive too close, even though it may not be considered tailgating, if the car in front were to panic stop at 75mph, I bet my ACC will do better than most of the others following way too close. It has actually taught me to leave more space.....way more.

My only gripes about the system are:
1)I hate that it turns off so fast when stopped. It makes no sense. I feel it should flash a warning after about a minute and allow you to hit a button to confirm that it should continue to hold. In stop and go traffic, the current version is annoying. I constantly find myself wishing for another 1 or 2 seconds before it cuts off. Even that would be a big improvement. I am hoping for a flash upgrade to this at some point.
2)When it "sees" the stopped car at the end of the radar field and you are going 55 as you approach a traffic light on a highway, it should begin to slow to a stop. It doesn't. That needs to be revised.

Other than that, the system is awesome. I have used it for 20K miles (2 years) and it works very well otherwise. I have driven for close to 4 hours straight and never touched the gas pedal or brake. Really cool.

I would expect it will be much better. The ACC is really made for highway use not around town. It is fun to use around town, but you have to be pretty careful.

The 2016 will still be missing lane assist which would also make a better overall safety package.

I believe both of these "issues" have been addressed in the 2016+ models.

The ACC w/Hold keeps the vehicle stopped for a longer period of time along with giving the driver the "HOLD" option for even more of an extended stop. And the 2016+ ACC will also now detect fully stopped vehicles in front of you.

Is that something that previous vehicles with ACC can be updated with? It sounds like purely a software thing if the vehicles already have the ACC installed.

Will there be a software update for 2015 models to get these changes, or is there a reason it can't be done?

I'm almost sure there is hardware involved. Right now it's a single radar unit based. I believe the new system adds a camera or more radar sensors. It needs more sensor information to know if something is stationary.

That's not to say there can't be software improvements to the current system. Like the extended hold feature should be purely software.


I believe the system is made by Bosch and it's probably a completely new generation system. New processors, sensors, etc. At least the current system is Bosch.


Chrysler 200 has LRR3 system. Not sure if current Jeep is LRR3 or less.
This is a link about the LRR4 system (not sure if that's what's going into the 2016 Jeep).

Driver assistance systems - Predictive emergency braking system - Multi purpose camera , Mid-range radar sensor , Long-range radar sensor , Stereo video camera , Radar/Video
Not disagreeing with you, but the pre-2016 system uses both the radar (eyeball) unit and the camera between the windshield and rear view mirror, working together.

Re: Im in love with the ACC

My guess is that they COULD update 2015 models to a more advanced ACC setup, but why would they? Its just more incentive for you to upgrade your jeep to the latest and greatest. (i would love to be wrong on this one)
