VEHICLE-MOUNTED UPDATE DEVICE, UPDATE PROCESSING SYSTEM, UPDATE PROCESSING METHOD, AND COMPUTER PROGRAM

摘要

A vehicle-mounted update device equipped with: a communication unit for carrying out communication with a first vehicle-mounted device, which has a storage unit storing a program in a rewritable manner, and a second vehicle-mounted device, which has a sensor for detecting persons in the periphery of the vehicle, and transmits a detection result indicating the presence/absence of a person in the periphery of the vehicle; and a processing unit for obtaining from the outside an update program for updating the program stored by the storage unit, and using the acquired update program to execute an update process for the program stored by the storage unit. When it is determined on the basis of the detection result received by the communication unit that there is no person in the periphery of the vehicle, the processing unit uses the update program to execute an update process for the program stored by the storage unit.
