The invention relates to a maintenance mileage calculation method and device of a range extender and a vehicle control unit. The method comprises the following steps: acquiring idling operation data, start-stop times and current driving mileage of the range extender; based on the idling operation data, calculating to obtain an idling equivalent maintenance mileage for the range extender; on the basis of the start-stop times, the start-stop punishment maintenance mileage for the range extender is calculated; and calculating the current equivalent maintenance mileage for the range extender based on the current driving mileage, the idle speed equivalent maintenance mileage and the start-stop punishment maintenance mileage. By adopting the method, the real-time performance and the accuracy of determining the equivalent maintenance mileage of the range extender can be improved, and a user can conveniently know the use condition of the range extender in real time and carry out regular maintenance.
