Control method for hybrid vehicle and control device for hybrid vehicle

A control method for a hybrid vehicle comprising a generator configured to charge a battery by using power of an engine, an electric motor configured to drive a driving wheel by electric power of the battery, and a particulate filter configured to collect particulate matter contained in exhaust gas from the engine, the control method comprising:

• driving the engine to raise a temperature of the particulate filter when a first temperature rise condition is satisfied in which a first predetermined amount or more of the particulate matter is accumulated in the particulate filter and the temperature of the particulate filter is equal to or lower than a predetermined temperature,
• prohibiting drive of the engine, even if the first temperature rise condition is satisfied, when a predetermined first condition that a driver does not intend to drive the engine is satisfied, and
• driving the engine to raise the temperature of the particulate filter, even if the predetermined first condition is satisfied, when a second temperature rise condition is satisfied in which a second predetermined amount or more of the particulate matter which is greater than the first predetermined amount is accumulated in the particulate filter and the temperature of the particulate filter is equal to or lower than the predetermined temperature.
