Abstract

A terminal, a vehicle, and a method for controlling the same are disclosed, which can perform a remote service mode upon receiving a Firmware Over The Air (FOTA) update notification message during a standby mode, and at the same time can download only the update file needed for the update function, such that power consumption can be reduced in the standby mode. When the standby mode is switched to a normal mode, the embodiments can update the corresponding software using the downloaded file, such that the number of update non-execution times caused by non-reception of the update notification message can be minimized. The embodiments can automatically access the server at a predetermined time during a normal mode so as to confirm the presence or absence of software to be updated, and can update the confirmed software, such that the embodiments can also normally update another software package.
