1. A center device, comprising:
a distribution control unit that is configured to:
control distribution of data to a first vehicle via a public communication network, the first vehicle including an electronic control unit which is a target for a program update and a vehicle master device configured to distribute, to the electronic control unit, data for the program update, the electronic control unit being capable of performing functions or performances based on the distributed data at the first vehicle; and
distribute, to the vehicle master device, a first command for controlling the vehicle master device to enable at least one function or one performance of the functions or performances of the distributed data;
a normal operation determination unit that is configured to determine whether the electronic control unit normally performed the at least one function or one performance of the functions or performances of the distributed data based on information received from the first vehicle; and
a distribution target expansion unit that, in response to determining that the electronic control unit normally performed the at least one function or one performance of the functions or performances of the distributed data, is configured to distribute, to the vehicle master device, a second command for controlling the vehicle master device to enable remaining functions or performances of the functions or performances of the distributed data, wherein
the distribution target expansion unit is further configured to:
not distribute the second command to the vehicle master device in response to the normal operation determination unit determining that the electronic control unit did not normally perform the at least one function or one performance of the functions or performances of the distributed data.
