<P>PROBLEM TO BE SOLVED: To provide a data storage device for a vehicle for improving the redundancy of backup data while suppressing the increase of costs of an ECU simplex. <P>SOLUTION: A first ECU100 is provided with: a first RAM140 for temporarily storing data; and a first data storage part 150 consisting of a non-volatile memory for storing backup data. A data transmission/reception processing part 120B transmits the backup data in the first ECU100 via a network to a second ECU200, and receives the backup data from the second ECU200 via the network. A data return processing part 220C of the second ECU200 stores the backup data from the data transmission/reception processing part 12B in a second data storage part 250, and returns the backup data of the first ECU100 stored in the second data storage part 250 via the network to the first ECU100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
