Abstract
A plurality of ECUs (communication devices) are mounted in a vehicle and connected to a communication bus. A relay apparatus (power feeding control apparatus) controls power feeding to the plurality of ECUs. The relay apparatus determines whether an abnormality has occurred for data received via the communication bus. If it is determined that the abnormality has occurred, the relay apparatus selects one of the plurality of ECUs, and stops power feeding to the selected ECU. After stopping the power feeding, the relay apparatus determines whether the occurrence of the abnormality has stopped. If it is determined that the occurrence of the abnormality has stopped, the relay apparatus maintains the stopping of the power feeding to the selected ECU.
