• the on-board device includes:
• an update information receiving unit configured to receive the update program or data transmitted by the update information transmission unit;
• an update information writing unit configured, if the update information receiving unit receives the update program or data, to stop the execution of the program or data stored in the first storage region by the processing unit, and to write the update program or data received by the update information receiving unit into the second storage region;
• a restoring unit configured to restore the execution of the program or data stored in the first storage region by the processing unit if the interruption unit interrupts the transmission;
• and
• an updating unit configured, after the writing of the update program or data into the second storage region is completed, to change a program or data to be executed by the processing unit from the program or data stored in the first storage region to the program or data stored in the second storage region, and
• the interruption unit interrupts the transmission of the update program or data depending on the biological information acquired by the biological information acquisition unit.
