IN-VEHICLE UPDATING SYSTEM AND IN-VEHICLE UPDATING DEVICE

摘要

Provided are an in-vehicle updating system and an in-vehicle updating device capable of preventing a battery from running out in association with update processing of an in-vehicle device. The in-vehicle updating system according to the present embodiment is provided with: an in-vehicle device supplied with power from one or more of a plurality of batteries mounted on a vehicle and operating by executing a program stored in a storage unit; and an in-vehicle updating device performing processing for updating the program stored in the storage unit of the in-vehicle device. The in-vehicle updating system is further provided with: a plurality of switching units for separately switching between the energizaton and the de-energization of power supply paths from the plurality of batteries to the in-vehicle device; a plurality of detection units for detecting the respective amounts of power stored in the plurality of batteries; and a switching control processing unit for, when the in-vehicle updating device performs update processing of the in-vehicle device, controlling the energizaton and the de-energization of the plurality of switching units on the basis of the detection results of the detection units.
