Patent ID: 11731607

Abstract:
A control method for a hybrid vehicle is provided. The hybrid vehicle includes an electric motor (13) that drives the vehicle to travel, a generator (12) that supplies power to the electric motor (13), and an engine (11) that drives the generator (12). The control method includes: when bringing the electric motor (13) into a regenerative state, operating the generator to drive the engine (11) in a state in which fuel supply to the engine (11) is cut, thereby executing, in accordance with required deceleration, the motoring control for consuming the output power of the electric motor (13); and when increasing the rotational speed of the engine (11) due to an increase in the required deceleration upon execution of the motoring control, setting the rotational speed of the engine (11) such that the change rate of the rotational speed of the engine (11) increases as the consumed power by the motoring control increases.
