## Abstract

An electric rolling stock control apparatus includes: a plurality of propulsion control devices that each control an electric motor for driving a car of a train, the electric motor being installed on the car, the train including a plurality of the cars; and a train information management device that calculates power necessary for the entire train, wherein the propulsion control devices each determine power according to a predetermined condition.

## Claims

### Claim 1

An electric rolling stock control apparatus comprising:
a plurality of propulsion controllers to each control an electric motor for driving a car of a train, the electric motor being installed on the car, the train including a plurality of the cars; and
a train information controller for calculating power necessary for the entire train, wherein
the propulsion controllers each configured to determine presence or absence of operation according to a predetermined condition, each propulsion controller including a storage to store the predetermined condition.

### Claim 2 (depends on 1)

The electric rolling stock control apparatus according to claim 1, wherein
the train information controller is configured to create information based on an operation command, and transmit the information to the plurality of propulsion controllers, the information being necessary for the propulsion controllers to determine the presence or absence of operation.

### Claim 3 (depends on 2)

The electric rolling stock control apparatus according to claim 2, wherein
each of the propulsion controllers is configured to transmit an operation determination result to the train information controller, the operation determination result being a result of determination of the presence or absence of operation.

### Claim 4 (depends on 3)

The electric rolling stock control apparatus according to claim 3, wherein
the train information controller is configured to monitor that the entire train is controlled with the power necessary for the entire train, based on the operation command and the operation determination results.
