Method for hybrid vehicle connected to network (versions)

FIELD: transportation.

SUBSTANCE: in the vehicle operation method, the vehicle is driven by a motor and an electric motor and the engine is started if the energy stored in the power storage device is greater than the upper threshold level when the amount of contaminants in the engine oil is greater than the threshold amount. In another version, the engine in the hybrid vehicle connected to the network is shut down in response to the level of contaminants in the exhaust line of forced crankcase ventilation. At that, the engine starts based on the level of contamination in the engine oil. In another version, at a high engine temperature, it is started in response to the amount of contaminants in the engine oil. At that, the motor is driven for a shorter duration. At a lower engine temperature, the engine is started in response to the amount of contaminants in the engine oil. At that, the motor is driven for a longer duration.

EFFECT: oil deterioration is prevented.
