Abstract

A used car subscription integrated management method executed on a used car subscription integrated management server according to the present invention comprises: a step of determining a grade for each used car by performing an evaluation of a used car subject to a subscription service based on a first evaluation criterion and calculating a first evaluation score; a step of processing a subscription by determining a final subscription amount using the grade for each used car and the option grade when a user requests to subscribe; a step of processing a subscription by determining a final subscription amount using the grade for each used car and the option grade when a user requests to subscribe; a step of calculating a second evaluation score by applying used car data before subscription and used car data after subscription based on a second evaluation criterion when the subscribed used car is changed by the user; and a step of determining whether to update the grade of the used car based on the first evaluation score and the second evaluation score.

Description

Method of providing used car subscription service and apparatus performing thereof The present invention relates to a method and apparatus for providing a used car subscription service, and more specifically, to a method and apparatus for providing a used car subscription service that classifies used cars by grade and allows a user to freely exchange and use a desired used car within a corresponding grade by paying a fixed subscription fee. Automobiles have established themselves as an essential means of transportation for modern people, and accordingly, methods of car ownership are also changing in diverse ways. In the past, it was common for individuals to purchase and own cars directly, but recently, various models for using used cars, such as leasing, renting, and car sharing, have emerged. In particular, car subscription services are gaining attention as demand increases for reducing the burden of maintenance and management associated with car ownership and for using used cars more flexibly. Car subscription services are a concept that allows users to freely access a variety of used cars for a fixed fee, offering consumers the advantage of switching vehicles as needed. For instance, flexible usage is possible, such as using a sedan for a specific period and then switching to an SUV for travel. This subscription model can be applied to both new and used cars, and the introduction of used car subscription services can be particularly beneficial in countries with active used car markets. The used car market is chosen by many consumers due to its advantages, such as lower prices compared to new cars and less burden of depreciation. However, purchasing a used car comes with several disadvantages, including concerns about quality and reliability, the burden of initial costs, and maintenance issues after ownership. Additionally, directly purchasing a used car results in being tied to a specific vehicle for an extended period, which limits the ability to experience a variety of used cars. To address these issues, services that provide used cars via a subscription model could be considered. A used car subscription service is a model that allows users to freely switch between various used cars within a predetermined tier during the contract period by paying a fixed subscription fee. Through this, consumers can drive a variety of used vehicles without purchasing a specific car and reduce the burden of maintenance and repairs. Furthermore, service providers can maximize the utilization of used cars, generate sustainable revenue, and establish more effective used car management strategies by analyzing subscriber preferences. Most existing car subscription services have focused on new cars, and there are relatively few subscription services utilizing used cars. While some used car rental and leasing services exist, the freedom to change used cars is limited because these services involve using the same used car for a certain period.
