Power feeding control apparatus, power feeding control system, and power feeding control method

A power feeding control system comprising:

• a plurality of communication devices that are mounted in a vehicle and connected to a communication bus;
• and
• a power feeding control apparatus configured to control power feeding to the plurality of communication devices,
• wherein the power feeding control apparatus includes:
• a receiving unit electrically connected to the communication bus and configured to receive data transmitted along the communication bus;
• and
• a processing unit configured to execute a process, and
• the processing unit is configured to:
• determine whether an abnormality has occurred for the data received by the receiving unit;
• if it is determined that the abnormality has occurred, select one of the plurality of communication devices;
• instruct to stop power feeding to the selected communication device;
• after instructing to stop the power feeding, determine whether the occurrence of the abnormality has stopped;
• and,
• when it is determined that an abnormality is present, the processor selects another one of the plurality of communication devices and determines if an abnormality is present, and
• when it is determined that the occurrence of the abnormality has stopped, maintain the stopping of the power feeding to the selected communication device.

A power feeding control method for controlling power feeding to a plurality of communication devices that are mounted in a vehicle and connected to a communication bus, the method causing a computer to execute the steps of:

• determining whether an abnormality has occurred for data transmitted via the communication bus;
• if it is determined that the abnormality has occurred, selecting one of the plurality of communication devices;
• instructing to stop power feeding to the selected communication device;
• after instructing to stop the power feeding, determining whether the occurrence of the abnormality has stopped, and
• when it is determined that an abnormality is present, the processor selects another one of the plurality of communication devices and determines if an abnormality is present, and
• wherein when it is determined that the occurrence of the abnormality has stopped, the stopping of the power feeding to the selected communication device is maintained.
