Abstract: The present invention relates to a big data-based vehicle rental service system for enabling a plurality of users to rent and use a vehicle jointly. According to the present invention, the method, which is a service for jointly using a vehicle by linking a plurality of users who have a fixed vehicle use time and non-overlapping use time, utilizes a system capable of measuring a vehicle usage result and the amount of used fuel for each user to solve problems related to joint use. When a person who wishes to jointly use a vehicle in a big data-based main server enters information such as a vehicle desired to be used, the time of use, the location for takeover/handover, and the gender and age of the desired joint user by using an operator's application and website, the system searches for and associates the desired vehicle with other joint users who have conditions matching shared user conditions and non-overlapping use time. When an agreement on the joint use is reached between the corresponding users linked to the big data-based main server, the operator rents the vehicle after signing a car rental contract with the users who wish to use the vehicle jointly. Each user opens a door of the vehicle by using a user identification card at a designated place, uses the vehicle during a designated use period of the user, and returns the vehicle to the original location before the designated use time of other joint users. Accordingly, the users can rent and use the vehicle jointly without purchasing the vehicle, thereby using the vehicle at a low price.
