Vehicle information control device with load management function

摘要

In general, a system of activating loads of a plurality of apparatuses based on priorities so as to set the current supplied to the loads of the apparatuses within a rated range is performed in a load management function in a train with a plurality of connected vehicles. Arbitrary selection of devices for limiting the load capacities from various devices with different load capacities is difficult in the system, when the load capacities of all apparatuses cannot be secured due to malfunction in part of the power supply devices mounted on the plurality of vehicles. Furthermore, the priorities or load limits need to be changed by hardware or software when part of the apparatuses with high priorities need to be limited to operate apparatuses with low priorities in the operation of the vehicles. The user cannot immediately set the priorities or load limits. Provided is a vehicle information control device with a load management function of limiting loads of apparatuses according to vehicle apparatus states within capacity ranges with a reduction in capacities of vehicle power supplies mounted on a plurality of vehicles and calculating and distributing surplus power.
