Powertrain, method for controlling powertrain, and device for controlling powertrain

摘要

A powertrain includes: an engine provided with a plurality of cylinders; a first motor generator coupled to an output shaft of the engine; and an ECU for controlling them. When misfire in the engine is detected, the output shaft of the engine is rotated by driving the first motor generator with ignition and supply of fuel to the engine being suspended.

1. A powertrain comprising:
an internal combustion engine provided with a plurality of cylinders; an electric motor coupled to an output shaft of said internal combustion engine; and a control unit that suspends ignition and supply of fuel to said internal combustion engine when misfire in said internal combustion engine is detected while a rotational speed of the output shaft of said internal combustion engine falls within a predetermined region, and rotates the output shaft of said internal combustion engine at a rotational speed falling out of said predetermined region by driving said electric motor until at least air in a cylinder in which the misfire has occurred is replaced, while maintaining the suspension of the ignition and supply of fuel to said internal combustion engine.
