Thread: Teach me about T/C

Its interesting watching when it cuts in and out even on tarseal. Different tyres make it behave different also (obviously) put cooper discover stt Maxx on my navara and they're meant to be an awesome tyre but they're lethal on tarseal in the rain, have faced back the way I came from once even with traction control and see the light come on heaps when its wet. On the flipside my Territory had some cheap and nasties on it when I got it and I put a full set of Potenzas on it and hardly ever see the light come on now. For a truck that does lots of off road I think you still cant beat a good old truck with lockers and manual everything

On both tarseal and gravel roads the easiest way I find to think about it is that the vehicle will keep trying to go where the front wheels are pointing. In an older vehicle you steer into a slide to correct yourself. In a newer vehicle with esp or tc or whatever you actually need to keep your wheels pointing to where you want to go and let the computer do its magic. Lots of people end up in the ditch with new vehicles as they get into a skid and try to correct it like they used to and so of course that's where the computer thinks you want to go... Once you understand what the vehicle is trying to do I think it's a really good feature.

Once disengaged and some wheelspin allowed it was off again no worries.
It seems to work well when on with some momentum and throttle say climbing a steep gravel driveway, it limits wheel spin and creation of corrugations but slow speed paddock stuff it will just get you stuck.

My work hilux circa 2015 would do the same thing in extreme conditions. Not so much braking form memory but the rpms wouldn't go above an idle no matter how much my foot was mashed to the floor to keep momentum up.
Even had a mine site inspector ask me how the hell it got as far as his v8 cruiser ute.
Very unusual to me

Easiest way to explain it would be that it's like ABS but when accelerating.
With traction control you can floor it on wet grass and the vehicle will sense the tyres spinning it applies the brakes to that wheel to stop it from spinning.

lots of vehicle have traction control for general driving but a few 4x4s/SUVs have traction control systems designed for off road use, they doesn't so much try to stop the wheels from spinning but tries to send power to the wheels with the most traction, it relies on sensing that a or multiple wheels have lost traction so will apply the brakes to those wheels to allow the other ones to drive (assuming no axle diff lock).
In low traction situations it's smart enough to not just lock up all the wheels and stop you from moving but depending on what mode you are in (if it has modes) then it will react different for sand or snow or tarseal.

When the missus and I were in Canada we got caught in a blizzard and the FWD hire car was not doing well in the deep snow.
With the slightest wheel slipage it would cut power until you virtually came to a complete stop, I think I turned it off eventually to allow me to actually drive the dam car.
