ABSTRACT:
An electronic odometer is disclosed, in which, in order to provide higher reliability, integrated traveled distance data to be stored in a nonvolatile memory is divided into three portions, i.e., high order digit data, medium order digit data, and low order digit data. A plurality of memories constituting the nonvolatile memory having the digit representative of the medium order digit data as the address thereof or as a part of the address thereof are selected, and the high order digit data which is required to be the most reliable of the three portions is written into at least three of the selected memories. The low order digit data is written into at least one of the rest of the selected memories. When extracting the integrated traveled distance data from these memories, the high order digit data is determined by applying majority rule to the data read out from the three memories. It is thus achieved to enhance the reliability on the integrated traveled distance data by the application of majority rule.
