Classification: G01F

Abstract:
A cruising distance calculation device provided witha fuel measurement means which measures stored fuel in a fuel tank when fuel is supplied to said fuel tank, a fuel injection measurement means which measures a fuel injection amount supplied to an engine, a running distance measurement means which measures a running distance of a vehicle, a remaining fuel calculation means which calculates remaining fuel by subtracting a fuel injection amount measured by said fuel injection measurement means from a stored fuel measured by said fuel measurement means, a fuel economy calculation means which calculates a fuel economy by dividing a running distance measured by said running distance measurement means by a fuel injection amount measured by said fuel injection measuring means, a cruising distance calculation means which calculates a cruising distance by multiplying a remaining fuel calculated by said remaining fuel calculation means by a fuel economy calculated by said fuel economy calculation means, and a refueling detection means which measures stored fuel in said fuel tank and calculates the difference between the stored fuel and the remaining fuel calculated by said remaining fuel calculation means, and when said difference is larger than a standard value, said cruising distance calculation means communicates to said fuel measurement means the fact that fuel is supplied into said fuel tank.
