Adaptive Cruise Control (in Audi A4, 2008 model)

[iJunglehazel]

Im getting that!

[123madhavan]

cruise control are for WOMEN!!!!!

[CNFxC]

It's a manual or an automatic transmission ? Or better said, could you equip your car with this adaptive cruise control in combination with a manual transmission, or just with an automatic one? Thanks.

[extremeriga12]

can anyone rell me the difference between accelleration cruise control and decelleration cruise control

please

thanks

[kwalliander]

Airline pilots do far less with their hands and feet at cruising speed, yet no aircraft designer would cancel the autopilot because it risks putting the pilots asleep. It's just a matter of doing your duty as a pilot ... and as a driver

[viperxx13]

its very good but with this application in to the car... you get SLEEP EASY... you are not in action when you drive... so you can easy sleep... this you can you when you are normal and for 10-15 minutes to be relax you foots only this...

[kwalliander]

@viperxx13 Hm, if you need pressing the accelerator to keep awake when driving, then perhaps you shouldn't be driving at all ;)

[McSaggler]

This is awesome. Great vid man.

[ryebread74]

do you know of any kits to upgrade vehicles without? when i was young, early 80's, my family would travel from indiana to florida to visit family for the holidays. i had lots of time to think on that 15 hour trip. i thought about developing this type of system due to the constant on and off again cruise control. cruise control was a high end feature then in our new road cruiser of a cadi. loved that car. i could sleep flat on backseat. anyway, should have done this but glad to see it out now.

[RoadNeki]

Hey guys...I found the best written literature on....... MyCarMyChoice (dot) com..... under tech funda it says how does adaptive cruise control actually work..and trust me it explains with the same conviction....

[erik4727]

Do we really want to grant lazy people the right to not even have to drive. it's not enough that they HAVE car.....

[scoot24925]

@erik4727 shit mate,in a long journey 50 km straight road you get bored to death just to drive straight and only on 120 km/h,just relax and let the CC do its job.

[erik4727]

@scoot24925 cool then

[joshharle]

First, great system, and definitely a stepping stone to much safer, efficient driving. However, I'm a little uncomfortable with the road discipline (or lack) that this system exhibits, and what would happen if everyone was using this.

For example, when the car first goes into the slow (right) lane, it is still going 140kph until it get close enough to the car in front. The camera does not look up as this is happening, but the Audi overtakes the car in the centre lane while this is happening.

[ben11522]

that is amazing!

[rickrossthebosz]

what engine and dtransmission?

[artash007]

thank you



[Charles2337]

I need this in my car.

[ervinski7]

What is the price of this option ?

[B789c]

nice video man very interesting. 3:24 a nice Jaguar XF passed you :D

[UltimatePisman]

Toch knap dat je niet door een politie werd gepakt, toen je 140 KM per uur reed.

Maar toch, wel een hele slimme gadget, en je auto ziet er erg lux uit.

[robrocktberlin]

Hmm, I see one problem: If your on the right or middle lane, you're not allowed to drive faster than a cars to your left!

So if you change lane to the right (eg. to make room for a faster car behind you) and there is a car on it in a big distance, the ACC can make you go faster than the cars to your left. It can even make you overtake a car to your left. It should acquire cars to your left, too. Great technology anyway.

[AlexShares]

I just don't see myself trusting anyone or anything but my own hands, feet, and brain while driving.

[thefoxbox2]

Thank you for this highly informative video! Can you please tell me what happens if traffic is very bad and all traffic comes to a complete stop (not suddenly, but just ends up stopping)? Does the car remain stopped, do you have to put your foot on the brake during the stop at all, or how does that work (at least with Audi)? Thank you!

[vladkpone]

is your car equipped with manual or automatic transmission?

[vVeazel]

What about curves?

[Charles2337]

@vVeazel

You just turn. 

[AMJudkins08]

Hi grate Demonstration, if the car in front slammed its brakes on hard would the adaptive cruise control do the same or would you have to brake hard? thanks.

[joewillgo]

What is the speed limit on that road? Plus, where are you driving where you can go that fast?

[B789c]

@joewillgo autobhan.

[carterson2]

You can connect your cruise to the wikiSPEEDia database using any smartphone.

[TboneCP407]

Excellent demo! Are you able to utilize conventional (non-radar) cruise control? I had an Infiniti that allowed you to use adaptive, or regular CC depending on your preference. The biggest reason for this for me is in case the radar has problems (rain, driving into the sun, or a radar malfunction) or when driving around turns, in which case ACC usually slows you down due to the turn itself (cosine angle effect.) Regardless, looks like a nice system and kudos for a great demo!

[nuuplaik]

very nice, i like it :)

[tmk85]

What if a car drives onto your lane. How intensive would the braking be?

[kwalliander]

@tmk85 it would brake right away, if it judges the distance too short

[ghidfg]

@kwalliander but what if theres a car right behind you?

[MisAnetta]

Does the audi a6 2006 model has it too ?

It's a break, quattro ... IT has a cruise control but i dont know if it has a ACC ?

[xYin]

good job! your vid is great!

[DannyHubbz]

Good demo. Wondering if the sensors are affected by rain and snow. If you have wet snow falling does the car tell you "no" because of the snow. Also does it work with in joint with traction control or ESP or ABS?

[kwalliander]

@DannyHubbz thx. It works perfectly save in snow and ice, as the system is connected to the ESP and ESP. In fact, I recently had an ESP failure, and the cruise control was shut down automatically

[Charles2337]

@DannyHubbz

It works on radar so I don't think snow or rain will affect it. The radar system is calibrated to only detect large objects like cars.

[alankkwong1]

Thank you for the very detailed explaination... Very well done!

[lodp]

nicely done

[TheHappyKamper]

Does the car also have a rear radar, to ensure it doesn't brake too quickly in front of other traffic?

[swunt10]

there is a law (in germany) that the car behind you has to choose a distance that is save in respect to the speed they (two cars) driving. so no. wouldn't make sense to crash into the car in front of you just because the idiot behind you can't drive his car adequate.

[kwalliander]

@TheHappyKamper no

[lekkimsm2500]

@TheHappyKamper You have to remember, fi the car behind you crashes into you because you had to do an emergency brake maneuver, he was to close to you. Braking to slow, in case something happens, is not an option

[ZannaBianca2012]

ACC is very helpful expetially during long distance driving.

[counterclockwise123]

this is a major step in achieving fully autonomous automobiles. the next car i get i will be sure it has adaptive cruise control because it is complete genius

[kwalliander]

@counterclockwise123 it doubles the value of any car

[lvan92]

2.0 TDI ?

[kwalliander]

yeap

[jellyboy123]

cruse control is cool.

dose the car brake if the car in front brakes.

[aznfx]

It does if u have watch till the End dumbass

[jellyboy123]

I'm talking about emergency stop , you're a very hateful person i would comment back but i think i let karma sort you out.

[martin20xx]

is this AUDI A4 better than the acura Tsx or TL??

[Liberaltedjo]

woooow, nice yea,

luxury, if 200kph can lock ?

[kwalliander]

maximum lock speed is 180 kph

[Liberaltedjo]

woooow, good

i want car like this, very relax yea, but steering wheel auto control or manual ?

very good, if medium sedan japanesse car available ACC ??

civic and corrola just can lock, maybe civic in there, in here civic doesn'e have cuirse.....

this audi A4 1.8T ?

[alterbr33d]

Can snow cover the radar detector?

[tonytan1994]

Question: When u start it. Can you start the car without the key in the ignition? Like having the smart key in your pocket and pushing the button in the middle.

[swunt10]

yes if you have paid for the keyless system...

[bangskeetband]

Nothing new...

[jorgekontor]

good way to demonstrate the adaptive cruise control.. very nice.

[MrStupidComment]

Do you have to steer? =P

[geeksquad2]

yep

[jjantao]

We have seen the system working on straight line.

How does the cruise control work in curve when the target gets out of sight? Does it accelerate?

In general how does the cruise control work on curve when the selected speed is higher then the safty one?

[kwalliander]

It also works in (not too narrow) turns. That means that the system must be "looking" sideways when the car makes a turn. It probably gets a hint from the position of the wheels

[swunt10]

mostly you use the adaptive cruis control on european highways or especially the autobahn. so there are no narrow curves, would be extream deadly at speeds up to 250 kph. and if there are narrow curves then there is a speed limit. and if you watched the video you know that the system works with seconds instead of distances. so at low speed the distance is closer than at higher speeds. so the target doesn't get out of sight.

[OpCzar]

Is there a radar behind you, also?

What if there was a car tailgating you and another one drives onto your lane. Would the system brake and possibly cause the rear car to crash into yours?

[kwalliander]

sure, but then again, that's what you would also do if you hadn't got this system, right?

[mercedesbenz4]

is it legal to videotape while driving?... anyway detailed vid

[kwalliander]

hm, interesting question

[kwalliander]

I never wanted to find out what would happen if you let the system take care of situation all by itself. In emergencies I step on the brakes instinctively, but the system always beats me to it. So it works fine.

[mihaisabotnicu]

Do you happen to know by any chance how the sistem reacts in the case of emergency breaking being required? Thanks!

[kwalliander]

it slams the breaks

[04smallmj]

*brakes

[Jebbie92]

Good demonstration :)

[SubmarineSquid]

Thank you so much for the video and narration. It was very professionally done. There is much "wow" factor in this technology.

Makes me want to say, "I want one!" Thanks again.

[kwalliander]

thx

[Barkster2]

What happens if you go up a steep hill - will it lose the radar lock on the car in front of you and therefore accelerate and the car in front which has now encountered this hill may well be slowing down. Zusammen-stoss perhaps ?

[kwalliander]

The radar does not seem to pick-up objects that are stationary (e.g. the through of a down-hill strech). It will just lose the lock. Sounds a bit academic, because in terrain that is that hilly, I wouldn't be using the ACC

[ankhenaten2]

hello,

does the cruise control work if you put your max speed at 20 km ph? i mean can you use the adaptive cruise control in traffic congestion? and is the cruisecontrol capable to bring the car to a complete stop while holding your foot on the gas pedal?

[kwalliander]

No, under 30 kph the cruise control does not work

[Moofie11]

it's crazy and genious BUT I LOVE IT!!!!!!!

[neodigy]

your demonstration is crisp and clear! thank you very much. now i know its system. hehe

[metalfab16]

that was cool

[kovacako]

And what is the minimum distance you can keep wit the system? Can you go below 1 sec? Can you just follow someone right in its tail?

[kwalliander]

Distance can only be selected in 1, 2 and 3

Actually, it nowhere says that these values represent a certain time rather than a certain distance, but is makes sense, as the distance increases with speed, without ACC setting having been changed.

Value 1 (the smallest distance) keeps you at about 1-2 seconds from the car in front., so it's not possible (for safety reasons, no doubt) to "hug its tail" with this system.

[benjeeqds]

What happens if somebody shoots radar at you... it slams the breaks?

[kwalliander]

No, it's is not sensitive to external radar waves.

What's funny though is that from time to time I see fast riders hit the brakes when the pass my car, for no apparent reason. Probably because they have a radar detector installed, and the radar of the ACC plays havoc with it ...

[neodigy]

LMAO

[swraman]

cool! 

i designed a acc controller for a class i took last semester, its cool to see a acc system actually operating on the highway instead of on simulation graphs!

[djalexr007]

I was about to buy an 2009 Audi A4, but i just heard in some videos that Audi cars have a lot of problems and need alot of work and maintnence after the 1 year or so...that things start messing up. like that trany, or the windows, or battery dies and stuff like that.. What do you think? have u had any problems with your Audi? as for me im changing my mind on buying the audi after hearing that story about audis.

[kwalliander]

The car is just over 1 year old now, and not a single problem, defect etc. so far

[hrford]

Nice video, obviously you guys don't have issues with "middle lane hogging" like we do here in England. It slows our motorways down!

[kwalliander]

It might, but people changing lanes all the time surely has a slowing effect as well. If everybody had an ACC, it would be possible for middel lane hogging to happen at much higher speeds, in a perfectly safe manner. Only if ...

[LordPalda]

Have you ever get into situation where like.. you traveled in left lane 140km/h, and someone who drove in richt lane for example 90km/h, ale he quickly cahnged lane, how the ACC reacted?

Otherwise, very rare and excelent video :-)

[kwalliander]

Thx.

I'm afraid that in that situation (sudden change in lane, high speed difference, close in front of your car) human intervention is required. The system works with quite a narrow radar beam looking forward, so it only starts reacting way after a human would, but heck, in such a situation even the best digital and human driver combined may not come out unscratched.

The ACC was never intended as an "hands off" system, but in say 95% of road situations it almost is ...

[radu231249320]

how much it cost?

[kwalliander]

about €1500

[flurry]

Very descriptive. Thank you!

[KPKonliner]

My dad's A4 has cruise control but he never use it !!!!!!!!!!!

[kwalliander]

Well, that sure is a shame

[KPKonliner]

useless technology !

[nistelsoi]

You are a retard. This technology make your journey much more relaxed.

[ototuit]

your father said the same thing about youtube

[kwalliander]

I just drove a 600 km highway stretch, touching my brakes or accelerator less than, say, 10 times. If you still think this technology is useless ...

[KiloByte69]

I was thinking about getting the new 2010 S4, looks like I gotta get this.  :)

[blankis1337]

First, your English is excellent!

Second, you have a fine taste in cars.

Third, that system is incredible.

Fourth, your video was very well done. Informative and interesting stuff!

[kwalliander]

thank you

[jambulaci]

thanks so much to this video, actually i got assignment from my Uni to make such things.. this video really open my mind,

[vhira]

Will the car stop to a hault if the car infront of you stops to a hault with the adaptive cruise control just like the new Mercedes S Class

[kwalliander]

Haven't tested it. Probably will. Anyway, you're warned enough by the preceeding braking

[DODwebdotorg]

From what I know, thats a limit on stickshifts. On the autos(tiptronics) you have 0-200-0km/h range with stop-and-go ability. Thanks for uploading this video, was very informative and well done - and well narrated. Love your car!

[kwalliander]

thanks!

[chesterchan2005]

do u have to controll left and right too?

[kwalliander]

no, ACC does not control steering in any way

[kwalliander]

It reduces throttle, idles and breaks, whenever required. The system is not operational though below 30 kmh. So in stop-and-go traffic jams, it each needs to be reactivated each time. But if the car continuously stays above 30 kmh, it works like a breeze. The car in the video has a handshift gearbox, so the driver has to follow with the gears when the car decides to speed up/down (engaging the clutch does not deactivate the system). I guess the system works even better with an automatic gearbox.

[bg1379]

Does it brake or coast to slow down when in heavy traffic?

[kwalliander]

Mine is a hand-shift box. It only reduces throttle. Putting it into neutral ("coast")obviously needs to be done manually.

[mosquiton001]

that's why i believe that this sistem is really best for the cars with auto gearbox.. put in D.. set the speed and distance.. and with the nav system basically all you have to do is turn the steering wheel... it 's a dream...

BTW nice ride i love the a4..
