INFORMATION UPDATING METHOD OF VEHICLE-MOUNTED CONTROL APPARATUS, UPDATE INFORMATION COMMUNICATION SYSTEM, VEHICLE-MOUNTED CONTROL APPARATUS, AND INFORMATION MANAGEMENT BASE STATION APPARATUS

摘要

When an updating event occurs, an information management base station unit inquires all the vehicles under its management about the presence or absence of vehicle-mounted control units to be updated. Based on replies from the individual vehicles, the information management base station unit selects the vehicles to be updated, and then it automatically updates them via wireless communication.
