Abstract: An apparatus for performing an over-the-air (OTA) update for a vehicle includes an estimated-time calculating device that calculates estimated time required for the OTA update of one or more controllers included in the vehicle, an update performing device that starts the OTA update based on the calculated estimated time, and a rollback performing device that performs an initial rollback on a failed OTA update once and to calculate a first value indicating whether a rollback is able to be performed on the failed OTA update in a case where the OTA update of at least one of the controllers fails when the OTA update is started.

Abstract: The present disclosure relates to a method and apparatus for controlling mass diagnostic communication in a vehicle capable to prevent a transmission error of a diagnostic message which can occur during mass diagnostic communication. The method of controlling mass diagnostic communication in a controller connected to a vehicle controller area network (CAN) communication network may include calculating a reception time interval between a previously received CAN frame and a currently received CAN frame, calculating a CAN frame processing time in the controller based on a length of data included in the received CAN frame, and determining a separation transmission period of a mass diagnostic message by comparing the calculated reception time interval with the calculated CAN frame processing time.
