Abstract
A car control device includes a driving force calculating unit that calculates driving force necessary for a train to travel; an operating number calculating unit that determines the number of M cars to be operated on the basis of the driving force; and a driving force command calculating unit that calculates driving force commands to be given to the M cars that operate depending on the number of M cars to be operated, wherein the driving force command calculating unit continuously changes the driving force commands when the number of M cars to be operated changes.
Claims10
A car control device for performing motor car selection control in a train including a plurality of motor cars to reduce the number of motor cars to be operated, the car control device comprising:
- a processor to execute a program;
- a memory to store the program which, when executed by the processor, performs processes of,
- selecting one of a normal mode or a motor car selection mode, wherein, in the normal mode, each motor of the train is operated, and wherein, in the motor car selection mode, at least one motor of the train is operated and at least one other motor of the train is not operated, and wherein selection of the motor car selection mode is made based in part on (a) the train having a speed that is higher than a threshold and (b) a determination that a preset time period has elapsed since a determination that wheel slippage has occurred in at least one motor car of a set of motor cars, of the plurality of motor cars, currently driving the train:
- after selecting the motor car selection mode, calculating driving force commands to be given to the motor cars that operate depending on the number of motor cars to be operated, wherein, in the calculating, the driving force commands are changed using jerk control such that the train is not jerked at switching of operation when the number of motor cars to be operated changes;
- and
- after entering the motor car selection mode, determining that a driving wheel of the train is slipping and switching from the motor car selection mode to the normal mode where each motor of the train is operated.
A car control system comprising:
- a train information management device comprising a first processor for managing train information;
- and a car control device comprising a second processor for the performing motor car selection control in a train including a plurality of motor cars to reduce the number of motor cars to be operated;
- and, wherein
- the train information management device includes:
- the first processor to execute a first program;
- a first memory to store the first program which, when executed by the first processor, performs processes of,
- selecting one of a normal mode or a motor car selection mode, wherein, in the normal mode, each motor of the train is operated, and wherein, in the motor car selection mode, at least one motor of the train is operated and at least one other motor of the train is not operated, and wherein selection of the motor car selection mode is based in part on (a) the train having a speed that is higher than a threshold and (b) a determination that a preset time period has elapsed since a determination that wheel slippage has occurred in at least one motor car of a set of motor cars, of the plurality of motor cars, currently driving the train:
- after selecting the motor car selection mode, calculating driving force necessary for the train to travel;
- determining the number of motor cars to be operated on the basis of the driving force;
- and
- after entering the motor car selection mode, determining that a driving wheel of the train is slipping and switching from the motor car selection mode to the normal mode where each motor of the train is operated,
- the car control device includes:
- the second processor to execute a second program;
- a second memory to store the second program which, when executed by the second processor, performs processes of,
- calculating driving force commands to be given to the motor cars that operate depending on the number of motor cars to be operated, and
- in the calculating, the driving force commands are changed using jerk control such that the train is not jerked at switching of operation when the number of motor cars to be operated changes.
