HYBRID VEHICLE ENGINE CONTROL METHOD AND HYBRID VEHICLE ENGINE CONTROL DEVICE Russian patent published in 2021 - IPC B60W10/06 B60W10/08 B60W20/14 

FIELD: transport industry.

SUBSTANCE: invention relates to hybrid vehicles. In a method for controlling an engine of a hybrid vehicle, when the electric motor is driven into a regenerative state, a generator is operated to drive the engine into a state in which the supply of fuel to the engine is stopped. Thus, in accordance with the desired deceleration, the electric engine mode is operated to consume the output of the electric engine. When the required deceleration is reduced and the engine actuation by the generator is requested, when the electric engine mode is operated, the engine speed decrease rate is limited to a value less than or equal to a predetermined value from the point in time at which the accelerator pedal depression value is changed.

EFFECT: driving comfort is improved.
