HYBRID VEHICLE AND METHOD OF ITS CONTROL Russian patent published in 2021 - IPC B60K6/44 B60W10/06 F01N3/20 F02D17/02 F02D41/30 

FIELD: transport machine building.

SUBSTANCE: invention can be used in hybrid vehicles. Hybrid vehicle (1) comprises multi-cylinder engine (10), device (18) for controlling exhaust gases, electric motor (MG2), electric power storage device (40) and controller (70), (100), (55). Device (18) for controlling exhaust gases includes a catalytic neutraliser configured to remove harmful components of exhaust gases from multi-cylinder engine (10). Electric power storage device (40) is configured to exchange electricity with electric motor (MG2). Controller (70), (100), (55) is made with possibility to control temperature rise of catalytic neutraliser at request of increasing temperature of catalytic converter during operation under load of multi-cylinder engine (10) in hybrid vehicle (1). In hybrid vehicle (1), multi-cylinder engine (10) and / or electric motor (MG2) is configured to output drive power to wheel (W). Controller (70), (100), (55) is configured to control electric motor (MG2) so as to cover the shortage of drive power obtained as a result of controlling temperature increase of catalytic neutraliser. Controlling temperature rise of catalytic neutraliser is control, which includes termination of fuel supply to at least one of cylinders of multi-cylinder engine (10) and enrichment of air-fuel ratio for other cylinders, different from said at least one cylinder. Disclosed is hybrid vehicle control method.

EFFECT: technical result consists in possibility to raise temperature of catalytic neutralizer to control exhaust gases and to supply sufficient volume of oxygen into device for control of exhaust gases, at the same time avoiding deterioration of road qualities of vehicle.
