1. A vehicle control method for a vehicle provided with a gasoline particulate filter that collects particulate matter contained in an exhaust gas from an engine, the vehicle control method comprising:
operating the engine with a lower limit set on an engine revolution speed when an accelerator is set to an off state by a driver while a temperature of the gasoline particulate filter is equal to or lower than a predetermined first temperature;
operating the engine with the lower limit set on the engine revolution speed when the accelerator is set to the off state by the driver while the temperature of the gasoline particulate filter is equal to or higher than a predetermined second temperature, the predetermined second temperature being higher than the predetermined first temperature; and
after the lower limit for the engine revolution speed is set, while the accelerator is set to the off state by the driver, continuing to operate the engine with the lower limit set on the engine revolution speed when the temperature of the gasoline particulate filter increases from a temperature at or below the predetermined first temperature to a temperature above the predetermined first temperature or decreases from a temperature at or above the predetermined second temperature to a temperature below the predetermined second temperature, until the accelerator is set to an on state by the driver.
