Problems solved by technology

[0006] However, it has been found that the engine torque is only determined by the torque map at low engine loads at the end of engine taming, and in vehicles with high engine loads at the end of engine taming, the optimum engine torque is not matched and thus engine fuel efficiency may be reduced

Abstract

An engine control method of a hybrid vehicle for controlling the engine depending on an engine load of the hybrid vehicle includes: learning a change amount of an engine load; determining at least one engine torque depending on a magnitude of the engine load; calculating an optimum torque value by using the learned change amount of the engine load and at least one determined engine torque; and controlling the engine by using the calculated optimum torque value.

Description

technical field [0001] The present disclosure relates to an engine control device of a hybrid vehicle and engine control thereof. Background technique [0002] The descriptions in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Hybrid vehicles efficiently combine power from an internal combustion engine and electric motors. [0004] Generally, a hybrid vehicle includes an engine, an electric motor, an engine clutch controlling torque between the engine and the electric motor, a transmission, a differential gear unit, a battery, an integrated starter generator (ISG) that starts the engine or generates electric power according to the output of the engine , and wheels. The integrated starter generator may be referred to as a hybrid starter generator (HSG). [0005] A hybrid vehicle performs torque distribution control of an engine and an electric motor in driving in a hybrid electric vehicle mode...
