发明名称 METHOD AND SYSTEM FOR DETERMINING OUTPUT TORQUE CAPABILITIES IN HYBRID AND ELECTRIC POWERTRAINS
摘要 A method for determining output torque capabilities in a transmission having a first, second, and third node, each of which has a speed and acceleration. The method includes 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 and second nodes, and calculating an inertialess maximum long-term output torque capability (inertialess max LT), which is identical to the raw max LT except that the inertialess max LT ignores torque capability due to acceleration of the first node. The raw max LT and the inertialess max LT are compared to determine an operating capability for the transmission. The first node may be an input node for the transmission. The method may include determining a new effective minimum long-term output torque capability (new effective min LT) by similar considerations.
