Gator Posted February 7, 2011 Report Share Posted February 7, 2011 Can someone explain to me how it works? And in 2wd vs 4wd? Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted February 7, 2011 Report Share Posted February 7, 2011 Displaces power being transferred. With traction control whether it is awd or 2wd the wheel that is slipping gets less power/wheel speed transferred to it and more to the wheels getting grip. These newer vehicles alot of them have computers and sensors that help monitor traction and think they work with the differential/differentials.

Shaun_300 Posted February 7, 2011 Report Share Posted February 7, 2011 With newer vehicles it's mainly controlled by the anti lock brakes and the throttle body. Each wheel has a speed sensor that the ABS module reads, when one reads higher it'll apply the brakes to that wheel to stop it from spinning, it'll also close the throttle plate on you to cut the power to the drive wheels. Older vehicles used different methods, like opening the EGR valve wide open to cut engine power when wheel slip was detected. A lot of newer vehicles also have stabilitrak which is a combination of ABS and traction control along with other sensors to detect if the vehicle is in a slide. It'll apply the brakes to a certain wheel(s) and cutting throttle to correct the slide picked up by the yaw rate sensor which is inside the vehicle.
