4eat: How does it divide torque between front and rear?
Posted: Thu Oct 27, 2005 2:02 am
As I read it, the tranny computer keeps track of the different
rotational speeds of the wheels and is constantly adjusting the division of
the torque--front to rear-- to eliminate tire scrub against the driving
surface. That's the clear part, the part I'm uncertain about is that I recall
that when the accelerator is depressed quickly at lower speeds the TCU
directs more torque to the rear before the rears can lose traction.
Obviously this is superior to a middle lsd that only tranfers torque after
wheel spin.
The other recollection is that when on a trailing throttle the tcu directs
more torque to the front wheels to assist traction when engine braking under slippery conditions.
Could be of seasonal interest.
