OTA UPDATE APPARATUS AND METHOD THEREOF

An over-the-air (OTA) update apparatus includes a communication device that receives data for an OTA update of software for vehicle from a server and a processor that calculates an expected update current consumed by a controller loaded into a vehicle in an additional OTA update proceeding subsequently, based on current consumption consumed in an OTA update of the controller, determines an update factor to be proportional to the expected update current, and proceeds with the additional OTA update based on that the update factor is less than or equal to a predetermined threshold.
