Patent ID: 8346489

Claim:
A method for determining output torque capabilities in a transmission having a first node, a second node, and a third node, each of which has a speed and an acceleration, the method comprising: controlling the speed of the first node; calculating a real maximum long-term output torque capability (raw max LT) as a function of at least the acceleration and the speed of the first node and the second node; calculating an inertialess maximum long-term output torque capability (inertialess max LT), wherein the inertialess max LT is identical to the raw max LT except that the inertialess max LT ignores torque capability due to the acceleration of the first node; and comparing the raw max LT to the inertialess max LT, and: if the raw max LT is greater than the inertialess max LT, setting the output torque capabilities of the transmission equal to the inertialess max LT, and if the raw max LT is not greater than the inertialess max LT, setting the output torque capabilities of the transmission equal to the raw max LT.
