Traction Control Test on Jeep Commander QT-II

[Mylovelycars]

Some people just don't understand how 4WD works.. nice vid btw:)

[SiNgLe4everq8]

first attmept 2WD

the secode 4WD

[shomb1989]

@SiNgLe4everq8 incorrect, i believe first attempt was 4x4, and the second was with traction control. ie, center diff was locked, but no lsd or lockers. as the video clearly states

[CompCrasher86]

Very nice, this system looks like it works very well for a scenario like this where you'd basically have a wheel off the ground with no traction. I would personally disable the ESP in the snow or flat terrain though because if you were going into a turn and lost traction it would try and straighten you out which, in a turn, will just make you understeer off the road. I'd rather have a controlled drift then understeer. I have an 01 Grand so we dont get any of this fancy traction stuffs ;)

Lock your dif bro

[ropoly]

99% don't understand how a 4WD works.

IF you have 4wd it doesn't mean that your all wheels will push the car. why? because it has differential and if you want to know what's a differential and how it works search youtube.

ههههههههههههههه شوفو الي كاتب الذكريات اخر المقطع ههههههههه

[wifebeater756]

torque goes to the weel that has less resentice so really its not 4wd its 2 weel drive one weel on each axel get a locker system and even amont torque will go to all 4 weels having TRUE 4x4

[codyxcaution]

GOD DAMN That is one steep climb it just made...

Great demo showing it pushing all the power to the front passenger, then easing on it to keep the grip.

i love the commander

With the Quadra-Drive II system, you don't need the traction control so much :P

Good video, though. Very good to show the effectiveness of traction control when off roading. Some systems don't work this well when at slow speeds like this.

[ROSCOANDBOPPERS]

whats the deal with the abs? i got 06 commander sport.

lacking balls offroad. cant even send dirt flying! should i remove the abs fuse?

[SandCommander]

Its the ESP and Traction Control System that prevents the wheel spinning.

You should turn off the ESP by pressing the ESP button for 5 secs until "ESP OFF" is displayed in the dash.

[jsachse1996]

@SandCommander does that also work on an o6 commander? if so, is it the button with the car with the lines behind it, because i thought that was traction control

[SgtoSousuke]

DONT!!

In Jeeps, ABS is used for multiple tasks, such as: Break alert (worn pads), ESP (when equiped), Standard traction control, Quadra-Drive (when equiped), and some other i cant recall right now. Deactivate as shown in the manual

[yamenad]

traction control is the best things done for off-roading- old days we used to push the car to its limits to do what today cars do easily.

[LovePontiac]

I don't understand why it couldnt get up in the first part. This is 4wd right? Shouldn't the front wheels have been able to pull it up?

[SandCommander]

The front right tire has no traction and all the torque going to the front axle was going to it.

[d21gtr]

@SandCommander Actually, torque was equal between the two tires. Torque was zero. Nothing to push back, so no torque. May sound wrong, but it's right. LSD's and lockers are what unequally divide torque, not an open differential.

[sirtubemaster]

@SandCommander i think you meant to say the left front right? the right front tire was on concrete and had traction. The left front was the one spinning with no traction

[offfiman]

It has open front and rear differentials. So when one rear and one front tire looses traction, it doesnt move. But traction control brakes slipping tires, when the torque goes on those tires which have traction, and car moves. :)

[Airox2009]

I don`t get it. The Quadra Trac II system should have automatic lockers in the front and rear but they don`t seem to work well.

[offfiman]

Quarda Drive 2 has Eaton ELSD's. Which are electronically controlled LSD's, that can move all the power from side to side. It's like traction control, but it's located inside the differential, and it's quicker, doesn't waste brakes. Still not as good as proper manually lockable diff. But anyway very good and easy system.

Quarda Track 2 does not have these diffs. :)

[lightyearmodels]

@offfiman

Acutally that is wrong. The current Quadra Drive II in the 05-10 Jeeps does have the Eaton ELSD's but they lock fully when either axle senses slip for up to 90 seconds or more. They act like lockers but you don't have to engage them. The computer does it for you.

[offfiman]

@lightyearmodels Exactly. But still, manually lockable diff, like in Wrangler Rubicon, is winner. Because, you can engage the locker before you get in trouble. Automatic locker has always a little reaction time and the driver does not have full control over it, like with manual lockers. Automatic lockers are good, but nowhere near as good as manual lockers, like in the rubicon wrangler.

[lightyearmodels]

@offfiman

It's really a matter of opinion. Do a search for Quadra Drive II and watch the video of the guy takin his 05 Cherokee up the waterfall. The computer engages the lockers so fast you never feel any slip.

[lightyearmodels]

@offfiman

Still not totally correct. They engage at the slightest slip...so fast that you the driver will never know they were not on in an off road situation. Meaning you will not loose traction as they engage. Further more they fully lock for up to 90 seconds after sensing slip and can stay fully locked if the conditions need it. The Eaton ELSD's are in fact fully lockable limited slips.

[TheJeepWheeler]

@lightyearmodels

wait so when the Eatons LSD's engage, thay stay enaged? no 2 tire fire back to 1 tire fire?

[lightyearmodels]

@TheJeepWheeler

Yes they stay engaged up to 90 seconds or until the computer can sense that no slippage is taking place. They act like normal lockers.

[TheJeepWheeler]

@lightyearmodels

sooo basically an electronic engagin locker

[killerkowalczyk]

@LovePontiac yes the vehicle is 4wd, look up "how do differentials work" on youtube. there is an old video from the 40's or 50's that explains differentials perfectly. When you understand how differentials work you will understand why this vehicle couldnt climb at the begining. later in the video the dirver activated the traction control, but on older vehicles you could lock the differentials manually so that all 4 wheels moved at the same rate.

[ngkful]

@LovePontiac with an open front differential all of the power was going to the left wheel which had no traction

[bestposted]

@LovePontiac Open Diff. 

[rangerover06sc]

notr bad for a tc system,wonder if the one in are expedition works as well
