1. A light-irradiation control apparatus that controls an irradiation device that is installed in a vehicle and casts light upon a road, the light-irradiation control apparatus comprising:
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs processes of,
controlling an output of the irradiation device configured to cast light upon a road,
acquiring information about a state of a vehicle platoon comprising a plurality of the vehicles traveling closely together,
controlling the irradiation device of the vehicle in accordance with the acquired information,
during no changes in a vehicle configuration of the vehicle platoon to which the vehicle belongs, performing control in such a manner that the irradiation device of the vehicle casts light in a steady-state mode that is common in the vehicle platoon,
in a process where the vehicle alone or the vehicle platoon to which the vehicle belongs, merges with another of the vehicle alone or another of the vehicle platoon, performing irradiation control for mergence in such a manner that the irradiation device of the merging vehicle casts light in a transition mode that is different from the steady-state mode, and
in a process where the vehicle alone belonging to the vehicle platoon or a plurality of the vehicles belonging to the vehicle platoon leaves the vehicle platoon, performing irradiation control for separation in such a manner that the irradiation device of the leaving vehicle casts light in the transition mode.
