Patent number: 7024306Abstract: A calculation unit (3) determines whether or not an operation which worsens fuel economy has been performed, and if it is determined that an operation which worsens fuel economy has been performed, the calculation unit (3) respectively calculates the actual amount of consumed fuel and an amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed. The calculation unit (3) then calculates an amount of fuel consumed in excess due to the operation which worsens fuel economy by subtracting the amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed from the actual amount of consumed fuel. A display (4) displays the calculated excess fuel consumption amount.Type: GrantFiled: July 24, 2003Date of Patent: April 4, 2006Assignee: Miyama, Inc.Inventors: Katsuaki Minami, Satoshi Kumagai, Takao Hamuro, Hideki Nagahara
