Abstract
A data-refresh apparatus performs a refresh control on a storage device being included in an onboard apparatus and including a NAND-type flash memory. The refresh control detects an error of all data and corrects a detected error. The data-refresh apparatus comprises a first refresh portion; and a second refresh portion that performs the refresh control when the onboard apparatus is installed to a vehicle and the vehicle subsequently becomes a predetermined service state. The storage device is written with data and subsequently soldered to a circuit board in manufacturing of the onboard apparatus. The second refresh portion includes a travel determination portion that determines whether the vehicle remains a travel state. The second refresh portion performs the refresh control while assuming that the vehicle becomes the predetermined service state, when the travel determination portion determines that the vehicle remains the travel state.
