A method for providing an autonomous driving service platform for autonomous vehicles by using a competitive computing and information fusion is provided. And the method includes steps of: (a) a service server acquiring individual sensor data and individual driving data through sensors installed on at least part of the autonomous vehicles including a subject vehicle; (b) the service server performing (i) a process of acquiring autonomous driving source information for the subject vehicle by inputting specific sensor data of specific autonomous vehicles among the autonomous vehicles and subject sensor data of the subject vehicle to data processing servers and (ii) a process of acquiring circumstance-specific performance information on the data processing servers from a circumstance-specific performance DB; and (c) the service server transmitting the autonomous driving source information and the circumstance-specific performance information to the subject vehicle, to thereby instruct the subject vehicle to perform the autonomous driving.
