Vehicle and control method and control device thereof

The invention discloses a vehicle and a control method and a control device thereof. The method comprises the following steps: determining an accumulated driving mileage of the vehicle; under the condition that the accumulated driving mileage is smaller than a first preset driving mileage, a first rotating speed fluctuation value of the engine is determined; under the condition that the accumulated driving mileage is larger than or equal to a second preset driving mileage, a second rotating speed fluctuation value of the engine and the accumulated use duration of the flywheel are determined, and the second preset driving mileage is larger than the first preset driving mileage; determining a target micro sliding friction rotating speed between the flywheel and the clutch according to the accumulated use duration, the first rotating speed fluctuation value and the second rotating speed fluctuation value; and controlling the clutch according to the target micro sliding friction rotating speed.
