Electric vehicle control device, train control system, and ground device

A train control system to perform idling-sliding control to reduce or prevent idling and sliding to which a train formed to include a plurality of motor cars by which propulsion force is applied can be subjected, the train control system comprising:

• a plurality of control devices installed on the respective motor cars to each detect idling or sliding that has occurred on the motor car, and provide idling-sliding control on the motor car;
• and
• a train control device to generate a prediction signal representing an anticipated occurrence of idling or sliding, and output the prediction signal to the control devices, wherein
• when the prediction signal is inputted, each of the control devices performs narrowing of a torque command value regardless of whether or not the idling-sliding control is being performed.

A train control system to perform idling-sliding control to reduce or prevent idling and sliding to which a train formed to include a plurality of motor cars can be subjected, the train control system comprising:

• a plurality of control devices installed on the respective motor cars to each detect idling or sliding that has occurred on the motor car, and provide idling-sliding control of the motor car;
• and
• a train control device to transmit location information of the motor cars in a formation of the train, to the control devices, wherein
• when idling or sliding is detected, a foremost one of the control devices in the formation generates a prediction signal representing an anticipated occurrence of idling or sliding, and transmits the prediction signal to a following one of the control devices, and
• the control device that has received the prediction signal performs narrowing of a torque command value regardless of whether or not the idling-sliding control is being performed.

A ground device to operate in conjunction with a train control system to provide idling-sliding control to reduce or prevent idling and sliding to which a train formed to include a plurality of motor cars can be subjected, the ground device comprising:

• a reception unit to receive, from the train control system, an idling-sliding level and spot information, the idling-sliding level being information about a degree of idling or sliding that has occurred on the train, the spot information being information about a spot where the idling or sliding has occurred;
• a storage unit to store the idling-sliding level and the spot information received, in association with each other;
• a computation unit to determine a control parameter for each set of the spot information in the idling-sliding control, based on information stored in the storage unit;
• and
• a transmission unit to transmit the control parameter associated with the spot information to the train control system.

A ground device to operate in conjunction with a train control system to perform idling-sliding control to reduce or prevent idling and sliding to which a train formed to include a plurality of motor cars can be subjected, the ground device comprising:

• a reception unit to receive a number of idling-sliding occurrences from the train control system, the number of idling-sliding occurrences being information about the number of times of idling and sliding that has occurred on the train;
• a storage unit to store the number of idling-sliding occurrences received;
• a computation unit to determine a time for inspection and repair of a wheel of the motor car, based on information stored in the storage unit;
• and
• an output unit to output idling-sliding history information including information about the time for inspection and repair.
