Method for Controlling Torque of Diesel Hybrid Vehicle

A system for controlling torque of a diesel hybrid vehicle, the system comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for
• calculating energy consumptions of an engine for respective engine torques within an engine torque range;
• calculating energy consumptions of a battery for respective motor torques within a motor torque range;
• calculating a plurality of total energy consumptions based on the energy consumptions of the engine and the energy consumptions of the battery;
• and
• controlling the torque of the diesel hybrid vehicle based on an engine torque and a motor torque that are relevant to the minimum of the plurality of total energy consumptions, wherein the energy consumptions of the engine are calculated based on a lower heating value of fuel, fuel consumption rates, and nitrogen oxide (NOx) emissions.
