Quick question about ATTS

Does ATTS switch power from one wheel to the other when one wheel loses traction, or does it only kick in when cornering?

atts is traction control...it reduces power to the wheel which is wheel spinning and adds power to the wheels which have most traction..a bit ****ty when u want to wheel spin. but fun in the snow..

Wrong.

ATTS is an electro-hydrolic LSD (NOT traction control).

It will NOT "kick-in" until it meets a series of criteria from various sensors. Wheelspin ALONE will NOT do it. It has to see a 15% difference in each front wheel's speed, AND sense some steering angle ( I forget exactly how much), AND see enough lateral G's from the Yaw sensor in the back of the car.

THEN, it will allow a series of wet clutches (just like in an auto tranny) to lock up, and distribute power to the wheel that needs it (in other words........the inside front wheel) to help pull you out of a corner.




In a straight line, ATTS doesn't do ****.

Go put one wheel on ice some time and try and accelerate..........NOT gonna happen

ATTS - Active Torque Transfer System

As bigbuls stated, is NOT traction control. In essence the bods at Honda have installed sensors in the cabin, and they take into account what the driver's arms are doing and how much he/she is sweating, and send the torque to the appropriate driveing wheel.



Ok, not exactly like that. The sensors are on the steering rack and on the TPS. So when the steering wheel is turned to x degrees and if the throttle is x% open, it sends 15% of the torque to the opposite side. However it is only operational on the Left wheel. (I think it's left, but it might be right)

So turning right, the left wheel rotates up to 15% faster than the right. When turning right, the left wheel rotates up to 15% slower than the right.
