FUEL SAVING DRIVING DIAGNOSTIC EQUIPMENT, IN-VEHICLE SYSTEM, DRIVE CONTROL APPARATUS, AND FUEL SAVING DRIVING DIAGNOSTIC PROGRAM

A fuel-saving driving diagnosis apparatus detects that a vehicle stopped, counts the number of stops, and determines whether the vehicle raced after detection that the vehicle stopped. After that, in the case where it is determined that the stopped vehicle raced, the fuel-saving driving diagnosis apparatus calculates the number of times of stop followed by racing done by the vehicle. The fuel-saving driving diagnosis apparatus diagnoses fuel-saving driving of a driver based on the counted number of stops and the counted number of times of stop followed by racing.
