Vehicle maintenance prompting method and device and vehicle

The invention relates to a vehicle maintenance prompting method and device and a vehicle and relates to the technical field of electronic control, and the method comprises the steps that the maintenance duration and the maintenance distance of the vehicle are acquired, if the maintenance duration meets a first preset condition, the working condition coefficient of the vehicle is determined according to the driving information of the vehicle, and the vehicle is prompted according to the working condition coefficient and the maintenance distance. And determining whether prompt information is sent or not, wherein the prompt information is used for indicating the vehicle to maintain. According to the maintenance duration and the maintenance distance, in combination with the working condition coefficient reflecting the working condition of the vehicle, the vehicle is prompted to be maintained in time, the maintenance prompting accuracy can be improved, and therefore the vehicle is kept in a good driving state, and
