a step of determining whether or not a person is present around or in the vehicle based on the detection result and the inside-of-vehicle detection result that are received;
a step of executing update processing of the program stored in the storage unit using the obtained update program when it is determined that no person is present around and in the vehicle so as to prevent an update from occurring when a person is around or within the vehicle; and
a step of transmitting, in a case where a predetermined time has elapsed without a person being detected around the vehicle, a locking instruction signal for instructing locking of a door of the vehicle so as to prevent a person from entering the vehicle during the update.
9. A computer program for causing a computer to execute update processing of a program stored in a storage unit included in a first on-board apparatus, causing the computer to execute:
a step of performing communication with a second on-board apparatus including a sensor that performs detection of a person present around a vehicle and configured to transmit a detection result indicating presence or absence of a person around the vehicle;
a step of performing communication with a third on-board apparatus including a sensor that performs detection of a person present in the vehicle and configured to transmit an inside-of-vehicle detection result indicating presence or absence of a person in the vehicle;
