Abstract
A coordinated torque control (CTC) system is provided that includes an engine capacity module, a multi-pulse enable module, and a catalyst light off torque reserve module. The engine capacity module determines a torque capacity of an engine and generates a maximum engine torque capacity signal. The multi-pulse enable module enables a multi-pulse mode that includes the injection of at least two pulses of fuel into a cylinder of the engine during a combustion cycle. The multi-pulse enable module generates a multi-pulse desired signal to operate in the multi-pulse mode based on the maximum engine torque capacity signal, a catalyst light off signal, and a brake torque request signal. The catalyst light off torque reserve module generates a torque reserve corrected signal based on the multi-pulse desired signal.
