1. A hybrid system for a vehicle having an engine and a driving motor, the hybrid system comprising:
a plurality of engine power generation modules configured to generate power with an operation of the engine;
a battery configured to store power output from the plurality of engine power generation modules;
a plurality of driving modules configured to drive the driving motor for driving wheels of the vehicle by power input from the plurality of engine power generation modules or the battery; and
a control unit configured to control operations of the plurality of engine power generation modules and the plurality of driving modules according to a required output of the vehicle;
wherein the control unit is further configured to:
derive an overall engine efficiency map from an individual engine efficiency map of each engine provided in each engine power generation module;
determine an operation order of the plurality of engine power generation modules; and
derive the overall engine efficiency map where a portion at which the fuel consumption rate is inflected to increase in the individual engine efficiency map of the engine of a first-operated engine power generation module is connected to an optimal efficiency section of the individual engine efficiency map of the engine of a next-operated engine power generation module.
