Integrating device and integrating method

摘要

An integrating device includes: a non-volatile memory for storing a value of an integrated running distance of a vehicle; an arithmetic processor for calculating a new integrated running distance by a signal generated at each predetermined running distance and also by the integrated running distance stored in the non-volatile memory; and a display unit for displaying the integrated running distance. The non-volatile memory stores a positive value lower than a predetermined reference value as an initial value of the integrated running distance, and the arithmetic processing means outputs a value obtained when the predetermined reference value is subtracted from the integrated running distance, to the display means as the integrated running distance in the case where a value of the integrated running distance stored in the non-volatile memory is not less than the predetermined reference value.
