Abstract: An apparatus and method for detecting a decline of fuel efficiency performance of a vehicle are provided. The method includes setting, by a controller, a fuel efficiency measuring reference mode and measuring average fuel efficiency based on data for each item based on the fuel efficiency measuring reference mode. Whether the fuel efficiency performance is declined is determined based on the average fuel efficiency measured value. A controlling apparatus that causes the decline of fuel efficiency is determined using data of the decline of fuel efficiency performance. In addition, a notification is output that provides the controlling apparatus causing the decline of fuel efficiency performance.

Abstract: A system and a method of acquiring data of an electronic control unit are provided. The method includes receiving, by a telematics server, information regarding a version of the electronic control unit mounted within a vehicle from a telematics terminal and searching for a configuration file that corresponds to the version of the electronic control unit. The telematics server is configured to generate an acquirement event file for acquiring the data of the electronic control unit using the configuration file and transmit the acquirement event file to the telematics terminal. In response to transmitting the acquirement event file, the terminal server is configured to receive the telematics terminal the data of the electronic control unit. In addition, data communication between the telematics terminal and the electronic control unit uses a controller area network (CAN) calibration protocol (CCP).
