PROBLEM TO BE SOLVED: To execute fuel consumption calculation while using distance measurement data used for an odometer or a trip meter even while functions of the meters are stopped. SOLUTION: Distance measurement data is acquired at times of detection of fuel consumption calculation start instruction, fuel consumption calculation completion instruction or vehicle stop respectively with using detection of those as triggers, and the acquired distance measurement data is stored. When fuel consumption calculation result output instruction is received, the stored distance measurement data is read out, distance measurement data acquired with using fuel consumption calculation start instruction as the trigger is subtracted from distance measurement data acquired with using fuel consumption calculation completion instruction or the last vehicle stop detection as the trigger to calculate distance of fuel consumption calculation section.
